If the system is low-power in architecture and has a single rail PSU, 300 watts should suffice, apart from the components specified. The device you linked to may suffice for you, as most people do not update their devices so drastically that the power requirements rise dramatically.

A Nvidia 1070 GTX can use up to 150 watts of power. The i7-7700 is estimated to consume 65 watts of power. So, you can now build a computer powered by the i7-7700K that can run at 300 watts. Most computers of this type are rated at 250-280 watts.

There are different types of power supplies. You can connect everything up to the maximum size of the power supply if it has a single +12v rail. It is possible to find power supplies that have two (or more) +12v rails. A 150 watt power supply and a 100 watt power supply can be placed together in the same chassis. A demonstration demonstrating you need more power than 300watts is much better.

As a marketer, I would guess that fewer than 1% of computers and perhaps 5% of gaming computers need a single-rail PSU larger than 400 watts. Gamers have been sold power supplies that are 1200 watts and even 1500 watts as though they were beneficial. Therefore, it has been recommended that every gaming rig have a minimum of 750 or 850 watts. Unfortunately, this is relatively rare and totally incorrect.

Quick Shopping Tips for the Best Graphics Card for 300 Watt Power Supply

You shouldn’t have a problem finding the perfect GPU if you know what to look for. AMD and Nvidia graphics cards currently come in a variety of flavors, so it is important to learn what to look for before jumping into one. Before buying a graphics card, you should take into account certain factors such as the display you are currently using, as well as the type of graphics you need.

A graphics card that gets equipped with 1440p or 2160p would be counterproductive if you opt for a full HD monitor. A powerful graphics card is required in order to play games on a 4K TV or gaming monitor.


You should always confirm if your graphics card will fit your computer before purchasing. You should make sure that when you are building your PC from scratch you are looking for the smallest graphics card that will fit.


Third-party graphics cards are often factory overclocked, which means that the graphics card has had its clock speed exceeded beyond its rating. In general, the higher the number, the faster the card will perform. Almost every card, including the entry-level ones, comes overclocked from the factory. You can usually overclock your own computer with the right software even without a factory overclock.


The best graphics card deals can be found by bargaining. To save money on any of the newest graphics cards, you should purchase them while they are on sale. Discounts of hundreds of dollars often accompany PCs from notable brands. CPUs are no exception.


Check whether the graphics card is able to connect to enough 6- or 8-pin connectors on your power supply. By purchasing an 80 Plus Bronze power supply, you can ensure this


Video RAM can range from 2 to 12 gigabytes on most graphics cards. Getting the most out of computers requires a significant amount of computing power. Some people say it doesn’t matter much, but others say it’s crucial.

Memory on video cards is usually used to store anti-aliasing operations and textures, as well as elements that help to make images more vibrant. These are very important factors. You can then use this number to decide how much memory your graphics card needs by dividing your system memory by two.


While some may debate the importance of GPU memory, bandwidth is critical to all. At any given time, the GPU can access a certain amount of memory. The data is fed into the shredder cores more rapidly if the GPU has a wider bandwidth. In consequence, video and game graphics work properly.

  6. Gigabyte GeForce GT 1030


The GeForce GTX 1650 was dropped from the product roadmap because none of the other Turing GPUs would be able to compete with the better graphics cards. On 12nm, this is undoubtedly the last version of the Turing architecture. There is now a Geforce RTX 2080 Ti that is powerful enough for ray tracing enthusiasts, as well as a GeForce RTX 2060 that is more affordable. Due to their lower prices, the GTX 1660 Ti and GTX 1660 lose the Tensor and RT cores.

The GTX 1650, like all Turing-based GPUs, will perform concurrent FP32 and INT calculations, increasing gaming performance by 15 to 35 percent over the preceding Pascal architecture (depending on the game).

Several improvements have led to improved results. A 1650 has more ram bandwidth and CUDA cores than an equivalent 1050/1050 Ti. The second difference is its speed. Thirdly, Turing GPUs support concurrent FP32 and INT calculations, which adds an additional 10% to 30% to performance. The performance of Best Graphics Card for 300 Watt Power Supply will depend on games and settings.

In the GTX 1650, NVIDIA introduced the TU117 GPU, which is designed to be a more affordable and smaller version of the GTX 1660 and GTX 1660 Ti GPUs. In the case of the 1660 rows and the 2520 rows, the most significant differences are the memory configuration and the number of SMs (Streaming Multiprocessors), which determine the number of CUDA cores, texture units, and row operations.

The GTX 1660 and the older GTX 1060 cards feature the same amount of GDDR5 memory. It has 128GB/s bandwidth, a tad more than the GTX 1050 Ti, thanks to its four active memory controllers and 128-bit bus. There are also 32 ROPs (Render Output Ports) on the card.

CUDA cores and 56 texture units are found in the GTX 1650, TU117, and GTX 1650 GPU cores. The GTX 1650 supports DirectX 11.

With a boost clock of 1665MHz, the stock GTX 1650 can theoretically achieve 2984 GFLOPS. In my case, I am using the MSI GTX 1650 Gaming X 4G, an overclocked card with a 6-pin PEG connection, but the GTX 1650 isn’t designed to have a 6-pin PEG connection by default.

Additionally, the GTX 970 is marginally slower than the GTX 1650 (1-3%) due to design changes in the last two generations. Newer games are more likely to use the GTX 1650.

Overall, the GTX 1650 is a good card, though less than optimal. My tests indicate it performed 55 percent better at medium resolution and 73 percent better at super resolution than the GTX 1050. In fact, the GTX 1050 Ti is about 30% faster than the 1050, due to the 1050’s small VRAM.


CUDA cores: 896 | Base clock: 1,485MHz | Boost clock: 1,665MHz | Memory: 4GB of GDDR5

  • Good performance per watt
  • Excellent performance per watt
  • The GTX 1050 is over 50% faster
  • Expensive relative to Radeon RX 570
  • Some versions do require auxiliary power
  • Struggles in more demanding games

2. EVGA GeForce GTX 980EVGA GeForce GTX 980

In light of its efficiency and (comparatively) low power consumption, the GeForce GTX 980 is an excellent choice for gamers who are looking to create a new system or to upgrade an older one in order to maintain steady connection speeds with displays above 1080p.

The GTX 980 enhances VXGI performance in a way that allows game designers to calculate global illumination in-game. This allows vibrant colors to communicate with each other in real-time rather than being reflected onto static surfaces.

A GeForce GTX 680 has double the render output units (ROPs) as a GTX 780. The increase in memory speed together with the increased clock speed (the stock GTX 980 runs at 1,126MHz to 1,216MHz) should enable performance improvements at high resolutions and with high anti-aliasing settings.

A power-connector specification suggests the AMD card will draw between 270 and 300 watts when it is loaded.

A new anti-aliasing method, dynamic lighting effects, and Dynamic Super Resolution are all included in the GeForce GTX 980. By rendering at a higher resolution and downsampling the results, it attempts to provide better image quality on low-resolution displays.

Nvidia claims that the GeForce GTX 980 features a leadup engine that cuts memory bandwidth requirements with 4GB of GDDR5 RAM.

The GeForce GTX 980 is the latest graphics card from Nvidia. There are a couple of new in-game features, a new architecture that emphasises efficiency, and, of course, DirectX 12 support.

For a few of our test games we played on a Dell 1080p computer, Dynamic Super Resolution was briefly tested. In the game’s configuration dialogues, higher “virtual resolutions” appear when I enable the Nvidia Control Panel option.

Three DisplayPort ports characterize the GTX 980 model card, which is a significant improvement over previous-generation Nvidia cards. You may also love to read: Best Graphics Cards for Fallout in 2024

The GeForce GTX 980 video card can support up to three of these monitors). Also, this device supports 4K resolution at 60Hz through its HDMI 2.0 port.

Compared with comparable AMD cards, this one runs cooler and consumes less power.

Several GeForce GTX 980 cards can be located near the reversible hatch. This increases cooling and ventilation. As a result of removing this portion of the backplate, Nvidia claims that the adjacent card’s intake fan will receive additional airflow.

With its Maxwell-based graphics card, Nvidia’s high-end graphics card is the most power-efficient gaming card to date. AMD’s Radeon R9 290X is a more powerful GPU with a similar price.


Base Clock: 1266 MHZ | Boost Clock: 1367 MHz | CUDA Cores: 2048 | Memory Detail: 4096MB GDDR5

  • Consumes very little power
  • PWM 14 phases large
  • Voltage regulation to a great extent
  • Test leads not included

3. Asus GeForce GTX 1050 Ti
Asus Geforce Gtx 1050

Six new GPU models are introduced by NVIDIA with the GTX 1050, the latest addition to the 10-series GPU line. If you can get past the limitation of 2GB VRAM, the GTX 1050 is one of the best budget graphics cards. The cheapest GPU on our list is the GTX 1050. Almost all machines sold in the last five years should be compatible with it, and it should be fine for gaming and light esports.

Samsung’s 14nm FinFET node is used on both cards based on the same GP107 GPU. In addition, the 1050 includes 2GB of GDDR5 memory (depending on what games and settings you select).

It goes much deeper than that. This is the simplest Pascal chip, offering only 640 CUDA cores. A 1.45GHz boost clock speed compensates for the lack of cores in this model.

The end result of Pascal’s quality is phenomenal. A GTX 1050 is considerably more powerful than a GTX 950. Those who say, “Yes, that’s just what I need,” will love the GTX 1050.

A 1050 will give you a substantial performance boost over integrated graphics with an x16 PCIe slot and an x8 PCIe link. The card is also a good option for HTPCs since it can decode HEVC just like more expensive Pascal cards, which are more expensive.

AMD graphics cards in the base PlayStation 4 and Xbox One versions perform worse than these cards. Most gamers, however, would need a card with a minimum of 3GB of VRAM, owing to their cards’ local video memory.

An EVGA plastic shroud houses the processor and a single fan, maintaining a cool temperature. The power consumption is the real surprise. With a TDP of 75W, the GTX 1050 draws its entire power from your motherboard. The top-of-the-line, overclocked PC on our Hitman test burned only 150 Watts, 61 Watts less than the RX 460.

Pascal’s power is best demonstrated by the GTX 1050, which is Nvidia’s best example yet. It does not achieve stellar benchmark performance, but as a replacement part for an outdated or disabled GPU, it is excellent, and it doesn’t require an upgrade to the power supply. It’s the Best Graphics Card for 300 Watt Power Supply available at an affordable price.


CUDA Cores: 768 | Graphics Clock: 1290 (MHz) | Processor Clock: (MHz) 1392 | Graphics Performance: High-6747

  • Extremely efficient
  • Excellent price
  • HDMI 2.0b, DisplayPort 1.4
  • Full HD support for all games
  • There is no support for SLI
  • It is necessary to drop some games to Medium settings

4. EVGA GeForce GTX 750Ti

EVGA GeForce GTX 750Ti

Green Team’s new 750 Ti video card provides gamers with a low-cost 1080p gaming solution. With its raw results, the 750 Ti has consistently outperformed the AMD cards. The 260X is nothing more than a rebadged HD7790, while the 750 Ti is built using Maxwell, Nvidia’s newest GPU architecture. 

Based on both metrics, the Nvidia 750 Ti performs 22 percent better than its 600 series counterpart. A feature of the 750 Ti is G-Sync, which allows games to run smoothly without stuttering or screen tearing.

What is even more impressive is that the 750 Ti does not require any extra power connections. The Dual-Link DVI port allows you to connect three screens. Two Mini-HDMI ports are available on the 750 Ti. Low-power video cards such as the 750 Ti consume only 60 watts.

R7 260X – AMD’s high-end graphics card – consumes nearly twice as much power compared to the R7 260. As for power consumption, it comes in at just 300W, so you don’t need to power it with a monster 500W or 750W. It’s a simple improvement for a wide variety of systems, because of this, and because of its limited scale.

There are 512 CUDA cores on the card and a 1020MHz base clock. In addition, it is equipped with 2GB of GDDR5 video RAM at a frequency of 5400MHz. The 2GB Ti version is a better choice if you intend to use different monitors, since you will have more video RAM available to you.

The 750 Ti was overclocked as high as 1169MHz using EVGA’s Precision X overclocking tool. All titles experienced no reliability problems, and their overall performance improved by about 5%, except Batman: Arkham Origins, which improved by just 3%. 

Just one slot is found on the card, which measures 5.7″ (14.5cm) long. I did not experience any significant changes in noise or cooling, and it was quite as quiet as it was with stock clocks. I think that’s a smart design decision, especially with the Steam Box revolution right around the corner.

Compared to both the R7 260X and the HD 7790, the 750 Ti uses less fuel and energy and outperforms them by 11%.


Cores: 640 CUDA | Base Clock: 1020 MHz | Boost Clock: 1085 MHz | Memory Clock: 5.4 Gbps

  • Excellent power consumption
  • Cool and very quiet
  • No SLI support

5. Sapphire Radeon NITRO Rx 460

Sapphire Radeon NITRO Rx 460

The approach is based on AMD’s fourth-generation GCN architecture, but the balancing has been changed for applications that require more power. As a competitor, it has a performance of up to 2.2 teraflops.

A base clock speed of 1090 MHz is shared by the processor and the boost clock speed is 1200 MHz. Overclocked to 1175 MHz base and 1250 MHz boost, Sapphire’s Nitro Radeon RX 460 OC received a positive review at our U.S. lab. Four 1GB GDDR5 memory ICs surround the GPU, totaling 4GB. Micron doesn’t mention them on their parts list, so all we know is that they have an 8Gb density and run at 1750 MHz.

In the meantime, the GPU is using the same power phases as the Asus Strix RX 470. Two M3056 MOSFETs handle the low side, and a M3054 MOSFET handles the high side. Both are manufactured by UBIQ.

A ITE 8915FN is used in the Strix RX 460 to monitor and regulate the current. The board is an orderly, simple, and well-arranged arrangement even if it should have been much shorter. At this price point, the materials are as you’d expect, but there are no noticeable flaws. You may also love to read: Best CPUs for RTX 3070 in 2024

The switch to a 14nm FinFET process means Polaris 11 is a new GPU, even though it shares some characteristics with its predecessors. Radeon RX 460 processors have 3 billion transistors on a 123 mm2 die, while Polaris 10 processors have 5.7 billion transistors on a 232 mm2 die. 

It also comes with a 360-degree-rotated six-pin power adapter. Also making a triumphant return is the four-pin connector that controls PWM-driven fans via card heat.

The Strix RX 470 uses a dual-link DVI port, but Asus shows three display outputs over the rear bracket. Only one DVI-D dual-link output, one HDMI 2.0b, and one DisplayPort 1.3 (ready for HDR3/1.4) are available on the Strix RX 460. A resolution of 4K at 120Hz or 5K at 60Hz is satisfactory.

With the exception of the two 75 mm fans, the cover is attached with four screws. When stress tests are run, the PWM-controlled fans do not exceed 4W combined, according to our measurements. There are two of them.

It’s the hottest edition in the GPU list because it competes with the previous 600 series. At this price point, one would not expect any flaws in the materials.


TDP: 75 W | Memory Clock: 1750 MHz | Memory Speed: 7 Gbps effective | Boost Frequency: Up to 1200 MHz

  • In many games, 1080p is fast enough
  • Budget-friendly
  • Power-efficient
  • Even in 1080p, performance has limits
  • Performance on par with the year-old GTX 950

6. Gigabyte GeForce GT 1030Gigabyte GeForce GT 1030

For the competitive games it is designed for, Nvidia’s GeForce GT 1030 performs admirably. Furthermore, due to the card’s low cost, power-efficient architecture, and attractive design, it can be purchased by almost anyone with a PCIe slot. Gigabyte has sent an updated GeForce GT 1030 Low Profile 2G to reflect Nvidia’s new entry.

In addition to the GP108, the GT 1030 is equipped with 1.8 billion transistors, a brand new graphics chip. This is a very small device, measuring just 70mm2 and it uses the same 14nm FinFET process as the GP107. However, the GK208 chip in the GeForce GT 730 is equipped with 1,02 billion transistors on an 84mm2 die.

Each SM and SMM in Pascal and Maxwell has 128 CUDA cores, so the GT 1030 has 384 cores. There are also eight texture units per SM on the GeForce GT 1030, for a total of 24 texture units. The GPU has two ROP partitions, which are capable of handling up to 16 32-bit integer pixels each clock cycle.

As for the GP108 and GM107, those partitions are aligned with 256KB and 1MB L2 cache slices, respectively. So, the Maxwell 512KB L2 limit is imposed on the GeForce GT 1030. A 64-bit interface is achieved by using two 32-bit memory controllers on the GT 1030.

Nvidia compensates for the GT 1030’s shortcomings in a big way with higher clock speeds. GPU Boost is rated at 1468 MHz. Our sample runs at 1227 MHz at base frequency. A 14 nm version of the GP108 graphics processor supports DirectX 12 in the GP108-300-A1. The GeForce GT 1030 will be able to run both modern games due to this.

Shader units in the game are 384, texture mapping units are 24 and ROPs are 16. There are 2,048 MB of GDDR5 memory and a 64-bit NVIDIA memory controller on the GeForce GT 1030.

In addition to the full-height frame, the card also comes with a thinner half-height bracket for enclosures with slim profiles. The same clock speeds are available in Gigabyte’s passive cooling model in addition to the active model. The passive model is passively cooled and low-profile.

Most of the device is connected to the GeForce GT 1030 through a PCI-Express 3.0 x4 interface. In addition to its single-slot cooling solution, the card measures 145mm by 69mm by 18mm.

The chip is awesome! Because it performs nearly as well as the 750Ti, it has a performance to power ratio that is approximately twice as high. Furthermore, it is ideal for a silent PC; the one that is passively cooled.


GPU Variant: GP108-300-A1 | TDP: 30 W | GPU Name: GP108 | Memory Clock: 1502 MHz

  • Starts at $70
  • Remarkably low 30W TDP
  • Vulkan Based games
