  • Quiet Good Working Inexpensive Quality PSU
Style: Semi-Modular Size: 650 Watts
I bought this for a setup case, and decided on this unit after much research for a quality inexpensive PSU that wont kill a new $200+ motherboard, and $300+ CPU... and a cheap PSU with 2X 8-Pin CPU cables that attach to the motherboard. I went with an 80 Plus Bronze unit from Corsair (good brand) because it will be used to setup a Gigabyte Z790 MB, Intel i9 12900K CPU, and NVIDIA RTX 4070 Super for short term only before I take it overseas. Soon after setting up my new stuff it'll power an i9 9900K + RTX 3060 permanently... which will still be used everyday when I'm in the USA as my main PC for gaming, light productivity, and web browsing... because an older i9 9900k & RTX 3060 are very very capable game players in 2024/25 if you don't listen to marketing hype about numbers... FPS...unnecessary 4K gaming... etc... So basically I decided on this budget PSU based on user/professional reviews, Corsair's reputation, and the fact I did not need a high-end PSU such as in my Corsair RM750X new computer... and something dependable & stable. ... show more

  • Corsair PS are reliable
Style: Non Modular Size: 650 Watts
Corsair PS have always been reliable for me This one has only 3 Hd connectors which is disappointing and the drive cables were short. I had to stretch and work the three into 3 SSD and it barely fit. Another disappointment. I never had a PS with these issues. Now I have to order some cable splitters for my other HD. I thought they usually came with 5 hd connections. ... show more
