Nice PSU, not as premium as my previous EVGA model but good value for money and a step up in power.Bought as a deal with CPU so the price was great.

Very good, never makes sound due to its 0 RPM fan mode. Got this to replace my 600W PSU but it was actually an unnecessary upgrade that I slightly regret, so be sure to double check whether you need such power. Anyway, quality and price for the power is one of the best, plus it's a very recent product refresh.

best value modular power supply you can get in my opinion, comfortably powering my 12700k and 3080ti, corsair even offer a dedicated 12pin psu cable (extra on website) which cleans up the build and of course plugs straight in. psu is pretty much silent and stays cool, always ran corsair psus and glad I chose this one.
