So I decided to open up my computer’s PSU and flip the large 120mm fan around so that it becomes an output fan rather than an intake fan (it is positioned right over my CPU heatsink and case exhaust fan). It has always had the problem where it “revvs” (turns on for a split second, then off, then on again) before POSTing, but it usually works eventually. Now it doesn’t seem to even get to the POST part, the system just hangs at boot.
I have checked and rechecked the connections, cleared the CMOS, etc.
This was not an cheap PSU…im using an Xtreme Vigor 500W which has scored 10/10 in multiple reviews, but I believe it is failing due to inadequate current.
If anyone has experience/insight into this it would be greatly appreciated, I don’t want to buy a new PSU for nothing
