Solved custom build, no power!

Specs: Windows 7
Hi,
I've just upgraded parts in my PC. was a few years old, built it myself then too. Got new motherboard, ram and processor. Connected everything and power lasted literally 1 second, then died and i cannot turn it back on again. So i assumed it was the motherboard at fault, and got it replaced. New motherboard arrives and i have the exact same problem! If i connect my old parts, my 850w power supply has no problem driving all incl an ati 6950 gpu. Now seems to not have power with new parts even without gpu
new parts:
processor :i5-3570K
motherboard: gigabyte z77-ds3h
ram: 8gb (2x4) crosair vengence 1600mhz

psu: Cute AP-850AS (Not cheap in its day)
cannot power this fella on with/without ram, with/without gpu.. please help

"Cute AP-850AS (Not cheap in its day)"

It's iCute, not Cute. And just because you paid a lot for it doesn't mean it's good. Multiple +12v rails & modular design?

Did you benchtest the board before installing it in the case? If not, pull it apart & do it right.

✔ Best Answer
Chances are that you left in the old or an extra stand off in your case and you are shorting out the motherboard from the bottom. Stand offs must be only under the specific spot that a screw is supposed to be. Not more, not less.
Do as riider says and pull it down and test just the basics outside of the case. A cardboard box (the motherboard's box is fine) is best for a test working surface and many use the non-static bag that the motherboard was packed in over the box as well. Use only the minimum for the initial test. Read the link he gave you above for details.

You have to be a little bit crazy to keep you from going insane.

Price can be a pretty good indicator sometimes, and who cares about the 'i'. Also ive built many PCs over the years, lose the "Do it Right' attitude, its not needed and frankly it just makes you come across as being pompous

@Fingers - your bang on, a screw plug was shorting it. Works fine now, thanks for your input

Glad to hear you solved it.
riider was right though, if you had bench tested it before you installed it you would have known it was working and you would have looked for possible shorts or other things that were changed from before it was in the case.
