    • Shockingly Nice
Style: 850W Gold|2 in 1 Color Size: 850W
Built a new computer 18 months ago and it has been running ever since. The computer is used for heavy graphics development and photography. It was very easy to install and works as expected. Extremely quiet when under heavy use ~~ any noise is overshadowed by the multiple fans. The included cables gave me considerable options on my build. And I would purchase again. ... show more

Style: 850W Gold|2 in 1 Color Size: 850W
Ive been using my pc for a year now. So now comes the reviews for parts. Power supply is great. Still going strong. Cables were easy to manage. Easier to manage this one then the other one I got that was DOA that was not a module ( def do not recommend non-module power supplys ) it works just how its should work. Theres no weird smells that some power supply can give off. ... show more

I bought this PSU when I upgraded to a 4070Ti Super GPU because I didnt want to use an adapter. It has ran flawlessly with my PC: Ryzen 5900X Asus X570 Pro 4070Ti Super 64GB GSkill Neos 2x NVME 360mm AIO 7x Thermaltake RGB case fans Asus ARGB LED controller USB devices Flawless. I run it through a CyberPower 1325 UPS with simulated sine wave. Power usage for my PC is between 210W and 580W according to the UPS. Pretty sure this PSU is white/black depending on how you install it in a standard PC case, and its fully modular, so there are no extra cables, but it has all of the cables I need. Cable adapters will always add resistance, latency, and increased power cost. ... show more

Picked this up for my build and I’m really happy with it so far. The clean design looks great, and I like that it gives you some flexibility with the theme ,it fits in easily with different setups. Setup was simple, and it’s been running perfectly. The fan is super quiet, barely noticeable even under load. Overall, it’s a reliable PSU with a nice look and solid performance. Definitely glad I went with this one. ... show more

Style: 850W Gold|2 in 1 Color Size: 850W
Perfect, I got a built that I ended up rebuilding mostly and sadly was dreading replacing the psu. Im glad I did, was a cheap psu and not nearly enough power for the 5070ti I swapped. ended up being far easier than I assumed and this is a much better psu and it being fully modular was great. All the Prime series from asus has been a great value. ... show more
