The 7900 XTX is a top-of-the-notch GPU and there are some people pairing it with some of the strongest processors, namely a Threadripper or Intel’s HEDT. In such cases, you will need a PSU capable of providing a lot of power and security to maintain your PC for a long time. After all, a PC is as durable as the PSU allows it to be.
The SS-1200XP3 boasts a powerful +12V rail, a fully-modular cabling design, and a user-selectable semi-passive operation. Which significantly reduces the noise output of the cooling fan when the load is low. Unlike many of its competitors that use 140mm fans for optimal airflow and minimal noise, Seasonic chose to use a smaller 120mm fan.
The unit also features exclusive use of Japanese electrolytic capacitors, which are known for their durability and longevity. And offers ten PCIe and two EPS connectors that are all available simultaneously, making it a versatile option for various high-performance builds. This power supply is also attractive for miners, as it has a large number of connectors. As the trend of crypto mining has decreased, some companies may lose interest in the high-capacity category. But, others may continue to release flagship models to showcase their technical expertise.
The PSU is able to deliver its maximum power consistently even at high temperatures up to 50°C. 80 Plus Platinum certified for high energy efficiency. As expected from a premium PSU, it is compatible with Haswell processors and features a fully modular cabling design for easy installation and cable management. Additionally, it is equipped with all the necessary safety features. It also has a semi-passive operation mode that can be deactivated via a switch for reduced noise output.
- Full power at 47 degrees Celsius
- High overall performance
- Quiet operation
- Low inrush currents
- Magnetic levitation fan
- Fully modular
- 10-year warranty
- In-cable capacitors
- Small distance between peripheral connectors
The Corsair RM850x is a great option for those looking for a versatile and efficient PSU. With dimensions of 86 x 150 x 160 mm, 80 PLUS Gold certification, and an ATX 3.0 form factor, this power supply has a wattage of 850W and uses a magnetic levitation fan for cooling. It also features fully modular cabling for easy installation and cable management.
One unique feature of this PSU is its hybrid mode, which keeps the fan off until it’s needed, resulting in almost silent operation. However, it lacks some premium features found in other high-end PSUs like the EVGA SuperNOVA. One potential drawback is that it doesn’t include the new 12VHPWR connector, so you may need an octopus connector that comes with most ATX 3.0 power supplies.
- Fully modular
- Great performance
- Full power at 47 degrees
- Cool and silent
- Highly efficient
- Not so tight load regulation
- Power Factor readings could be higher
The Cooler Master V850 V2 Gold is a powerful and efficient PSU. It can handle the power requirements of a high-end GPU such as the RX 7900 XTX. Its platform is designed to deliver high performance and save you money on electricity bills. While it may not be at the top of its class, it is still a solid choice that is worthy of consideration.
Its major competitors in the 850W category include the Seasonic Focus Plus Gold 850, Corsair RM850x and RM850, XPG Core Reactor 850, and the Super Flower Leadex III and V models. With the recent release of demanding high-end graphics cards from Nvidia and AMD, the 850W category has become increasingly popular. Since these cards require a strong power supply to function properly.
This PSU offers ample connectivity options with two EPS and six PCIe connectors. It’s noteworthy that it comes with three PCIe cables, which can be utilized in high-end VGAs with three PCIe sockets. It is worth noting that it is recommended to not use both PCIe connectors of the same cable with high-wattage graphics cards such as Nvidia’s. But, the 7900 XTX should not pose a problem. The number of peripheral connectors is sufficient, however, it could be improved by having more space between them. On the downside, it does not have in-cable capacitors.
Features and considerations
The first thing to bear in mind is the recommended PSU capacity for the 7900 XTX. According to AMD, a 750W PSU will suffice to feed the GPU and the rig.
However, we consider that amount a bit on the edge. It won’t leave you any space for overclocking or even upgrading other components of your PC to be more power-hungry. So the first thing to consider will be that the PSU has a wattage of at least 850W.
The second thing to consider is the efficiency rating of the PSU. A high-efficiency PSU will use less power to run, which can save you money on your electric bill and help keep your PC running cooler.
Look for a PSU with an 80 Plus rating of at least Bronze, which means it’s at least 82% efficient.
Another important factor to consider is the number of connectors and the type of connectors available on the PSU. The 7900 XTX requires one 8-pin and one 6-pin power connector.
So make sure the PSU you choose has those connectors available. Additionally, it’s a good idea to choose a PSU with plenty of additional connectors for other components in your PC, such as extra hard drives or fans.
Our Verdict
In conclusion, when searching for a PSU to power the 7900 XTX, it is important to consider the wattage and efficiency of the PSU, as well as its number of connectors and its noise level. The Thermaltake Toughpower GF3 ATX 3.0, Seasonic SS-1200XP3, Corsair RM850x, and Cooler Master V850 V2 Gold are all great options for powering a high-end GPU like the 7900 XTX. Ultimately, the choice will depend on your specific needs and preferences, but any of these PSUs will provide the power and stability required to run the 7900 XTX smoothly and efficiently.
