Just put together a new HTPC. It doesn't post when PSU switch is turned on. No fans spin, nothing. I tested the PSU disconnected from the mobo with a paper clip and just a fan connected and it powers on. Tried clearing CMOS, reseating ram, etc, running with minimal components, etc. I haven't touched the cpu yet, but I don't see what I could've done wrong.. Both ATX and ATX 12v were plugged into the mobo. Could there be something wrong with the PSU? The fan spins pretty slowly when it does run, I've had it for a month or two before I picked up the rest of the parts.. Could it not be giving enough power to the motherboard? Like I said it does power at least 2 fans when paperclipped'.

I had originally put it in an older case for the time being while my HTPC case is in the mail, which has enough mounts for the left side and half way down the board. The tray ends before the right side, so I could not mount that end. I did put the ram in and what not first which is on the right side so I didn't bend the board when installing. Could I have killed the board by not mounting it at every possible spot?

Also, the board is out of the case and on my desk on the box at the moment, and still does not power on. So it's not like the case is shorting it. Unless it already fried before...



Specs are:

Gigabyte GA-MA785GM-US2H
AM3 Athlon II 245 Regor
Corsair HX520W
WD 640GB Blue
WD 1TB Green
4GB G.Skill 1066


I'm not sure if the mobo was DOA or not. That's what I'm leaning towards.


Help/suggestions? Can I rule out the PSU being bad? It powers on paperclipped, but does not when connected to the motherboard.


This isn't my first build, about my 4th or 5th so..

Thanks in advance.

It's on my desk, not in a case anymore. I mean it doesn't power on when the switch is flipped on the PSU.

So you're now jumpering the power pins on the mobo right?
 
I'm such such such an idiot. My god.

I'm ashamed of myself. :p


Thanks Danny, I wasn't even thinking about the mobo power on. Now that I hooked up a power switch, all works fine.
