Speaking of psu, I searched up my psu on youtube, and the only reviews I see are from 4-7 years ago... I'm kind of skeptical. 620w is good and can handle a lot, but why does it seem so outdated? Kind of worried.
As long as it works it should be ok because it is a HX series which are good PSUs, If you want a new PSU the CX series are cheap and reliable or you can see some seasonic or XFX.
