nice job Kenneth, if you are able to you really should get rid of that fan as removing it will cure a few potential problems - vibration, odd magnetic fields and noise on the power line. When I did it, it wasn't a night and day change but well worth it. I replaced it with a large heatsink but I did have one of the lower power-rated CPUs.

analog-sa

What did you do for the -12V? Did you simply leave it unconnected?

I'm sure analog-sa will be along in a minute but maybe this will help. -12v is pretty much legacy for the ATX spec and many motherboards will boot up comfortably without it. However, it's pretty much test yours and if it does you're in luck. If not, then you'll need -12v.

Precisely. My MB does not require -12v.

Thx. I have an ASRock Z87E-ITX mobo and am building a linear PSU. I'm hoping I can simply leave the -12V disconnected. I guess I could test with an extension between the ATX socket and the existing picoPSU, simply cutting the -12V supply and seeing if it will boot...
