    Been using Corsair PSUs for a long time. Always reliable and dependable. I will never cheap out on a PSU and even with the X models of Corsair costing way more, I’ll pay the extra. The X models of these PSUs have Japanese Capacitors instead of the 1000e using korean/taiwan capacitors.

    Pretty much overkill if you don't have a really demanding PC. Even for my build, it's almost 200 Watts higher than necessary.

    Shake your PSU a bit before putting into case…

    Purchased this as my first Corsair PSU…was going to go with the HX1200 but there wasn’t any stock when purchased. When I opened the box and took the PSU out, there was a rattling noise…turns out there was a free screw floating about in there! Got the screw out and it’s been working fine. Will probably still end up with the HX1200 once I upgrade my GPU to a 4090 though. Hopefully they work out the QC issues with these because after some research, I’m not the only one that’s had issues with this particular PSU.

      Posted .

      Hello,

      Sorry to hear you ran into this problem, definitely not something that's normal nor does it happen often but I've unfortunately heard of this and it's indeed an assembly QC issue. Do reach out to our team online directly on our site for any assistance you may ever need.

    It's a power supply from Corsair. It works. It doesn't explode, like other brands. What more could you want?
