It was $40 and it's (supposedly) 80+ gold certified. I'm trying to be cheap while at the same time trying to achieve reasonable efficiency. Other than it being 50watts shy of being future-proof, why should I replace it entirely?
I checked out your PSU tier list and many of the problems with the PSUs listed are extremely vague. The matching list of recommended PSUs is insanely limited. The list says this particular PSU has bad caps, thin wires, and no protection. I looked all this up and the caps are decent (Teapo brand is ok, the few CapXon caps are solid, not electrolytic, so those are fine), the wires are fine (no article even mentions the wires, pics reveal nothing unusual), and there most certainly is protection (some articles insist there is too much protection). Many articles even compliment the design and manufacturing of this PSU.
So I ask, WHY replace this PSU? Some actual reasons would be great. None of this "X brand makes me feel Y" rubbish. Is it normal for the -12v rail to be sitting at -5.67v?
