[QUOTE="mpinho, post: 1741007, member: 385782"] Hello, Since I had the PSU out of the chassis, I decided to measure all the rails. Conclusion: Only one 5V rail is outputting a wrong value, all the others seem to be just fine. The "bad rail" is the one found on the PSU's J4 Molex under PS_on. [ATTACH=FULL]25483[/ATTACH] [/QUOTE]
