Garth Clark says:

Here’s your PSU spec’s:
80 PLUS Platinum certified, delivering up to 92% energy efficiency under real-world load conditions. Key word here is “up to” but not at full load, at 50% load or 380W.

Marcello says:

I have a 450 w psu and it runs perfectly i have i5 4690k and gtx 1050ti and 12 gb ram
