accidentally plugged fan connectors into mobo backwards.

[Roshio]

I finally got my first build up and running except for the fans. I have a haf 932 advanced and a couple of the fans plugged into the psu wouldnt work, but the other 2 would. So I decided to plug the 4 fans into my mobo's 4 fan headers. Unfortunately, cooler master makes these case fans' wires +red, -black, and ground some other colors. I assumed black was ground and I think I plugged them in bcakwards because when I went to start up the computer again everything started for a split second then shut down until I removed the power. I unplugged all the case fans and tried again but the computer still only starts for a split second and dies, although when it's plugged in the mobo's individual power button light still comes on.

Did I fry some part of my mobo or psu? please help

I have a silverstone 80+ gold 850W psu and a gigabyte z77x-ud3h motherboard with a coolermaster haf 932 adv. case

I'd guess some or all the +12V circuits on the mobo are toast.

Putting those connectors on wrong must have needed some force? Usually the pins and plugs are mated so they can't be put in the wrong way.

The headers on the motherboard only have a small tab but it seems like the connectors are set up backwards, either way I double checked the manual and turns out i shorted my power supply. luckily the psu is a beast and i had to just flip it from off to on a bunch of times with the power connected and it fixed itself.
