    • Awesome Power Supply
Size: 1000W Color: Black
It really like that this power supply came with braided cables which made it easier for cable management. One of the small gripes I had with my old Seasonic Focus is that the cables were stiff but I really like that these are flexible. You can't go wrong with Seasonic, my old Seasonic is still working awesome with no issues, I had to replace it because I bought a new graphics card so I wanted to future proof my pc and not worry about meeting the minimum power requirements in the future. I have my old Seasonic for about 6 years and never had issues with it, I like that they are reliable and don't have to worry about them giving out on me while I game. The power supply was easy to install and it is really quiet, even under load. It came with all the cables I needed plus more. I definitely recommend if you are looking for a really good power supply, they are built really well and will last you a long time. ... show more

    • The Perfect Finishing Touch for White Builds
Size: 1000W Color: White
This power supply is the missing piece to complete my white build. The finish is premium and, unlike others, the cables are also completely white and of excellent quality, which makes cable management much easier and visually enhances the interior. Besides being aesthetically flawless, it is extremely quiet even under load. It is the perfect combination of style and reliable power. ... show more

    • Super quiet
Size: 1000W Color: Black
Power supply is fully modular with very high quality wires and wire coatings, cables are very flexible, extremely easy to manage and run on the backside. I didn't realize how loud my old power supply was until using this one, whisper quiet!!

    • Solid and great value
Size: 1000W Color: Black
Solid power supply, very quiet, and a great value for the money given how prices lately have gone crazy. I normally prefer to run even higher-end power supplies (Platinum or Titanium efficiency) but was stuck in a situation where an easy, fast PSU swap for the money mattered more than ultimate effiicency, and the Seasonic Focus GX ATX 3.1 units are still very, very good. ... show more

    • Great psu with plenty of power......good choice.
Size: 1000W Color: Black
Nice look, heavy so you know it's got good components, great looking/flexible wires to make your rig look good and route easier and the modular attachments are just what you need to use only what's necessary. Have had a seasonic psu for years without a hickup, wanted another one for my upgrade. Extremely happy with this purchase. ... show more

The cable management is excellent thanks to its modular design, allowing me to use only the necessary cables. It has been very reliable with no failures, runs cool, and is a great choice for future upgrades, especially when I upgrade my graphics card.

    • Amazing power supply
Size: 1000W Color: Black
Installed this in an NZXT dual chamber case and it was perfect. The cables were easy to manage, the installation was a breeze, and the hybrid mode makes it nice and quiet unless it has to turn on the fan. The 12VHPWR connector also seated snug into the 5070 I used, so I have no doubt it won't have melting issues. ... show more
