Right now, the most powerful graphics card for gamers is the Nvidia RTX 5090. If you own one of these latest GPUs, you already know that the entire RTX 5000 series is incredibly powerful. That also means you need a high quality power supply that can deliver stable power without limitations.
A power supply designed to handle only 600W is simply not enough because the RTX 5090 has a typical power draw of around 590W on its own. On top of that, the rest of your PC also needs power to operate, especially the processor, even though it consumes much less power than a flagship graphics card.
For that reason, one of our top recommendations is the Seasonic Focus GX power supply. It is designed to provide reliable, high quality power for demanding gaming PCs. Below are its main features.
Seasonic Focus GX Power Supply Features
The Seasonic Focus GX delivers excellent performance with continuous power output of up to 1000W. It is built for high end gaming PCs equipped with demanding graphics cards like the RTX 5090. This is one of the main reasons why it is considered one of the best rated power supplies of 2026.
It is fully compatible with the latest ATX 3.1 and PCIe 5.1 standards, making it ready for modern hardware. It also carries both Cybenetics Gold and 80 PLUS Gold certifications. To put that into perspective, Cybenetics certification requires much stricter testing and quality standards than 80 PLUS certification alone, making the Seasonic Focus GX a true high end power supply.
Like most modern power supplies, it includes all the necessary cables for installation, so you won't need to purchase any additional cables.
Does it include a warranty?
Yes. Seasonic backs the Focus GX with a 10 year warranty, which is well above the 5 year warranty commonly offered by many other brands.
