So I got a mini ITX case but the included 150w PSU doesn't turn on. I hooked up a PSU tester and it shows an active 5VSB but it doesn't turn on even with the paper clip method. I opened the PSU as I suspected that maybe the green (PWROK?) cable was unsoldered or something but it's soldered fine. The issue is that the store doesn't have it in stock anymore so it can't replace it and the PSU is custom, almost like a FTFX PSU but shorter (FTFX is 65x85x14 this one is 65x65x14). I already contacted the manufacturer to see if I could get the PSU replaced and I could return the case and get a refund but I wanted to check with you guys first. Any ideas? Googled a lot of things but didn't find anything useful.
