Fans spin, then they go off, no power

[squasher]

I have just put together a new build
2400+
9600 powercolor
400w fsp n/p psu
NF7
512 stick of ch5

I hit the switch at the back of the psu and I get the red "ready" light from the mobo. Then I hit the powers switch. The cpu fan and the psu fan(I don't have any others in right now open case) spin for a second, but then they stop. The ready light remains on.
I have tried other ram and looked for shorts and I am at a loss of what to do. Any suggestions?

I tried to short my psu to see if it would go on, when I did the psu fan spun about once then stopped. Is this an RMA?
Its a 400w fortron N/P

Did you use the correct risers? Make sure the back of the mobo is not touching the case.

[edit]Try just powering without hds/cdroms etc [/edit]

You need to adjust the ovp protection inside the psu That will of course void your warranty. It's the 2 in the middle if I remember correctly. Turn them counter clockwise so it would a lot of voltage for it to trip

The problem is, if it is broken I really want to rma it, I saw a powersuply tester at circuit city, would that help?

How old was this fortron anyways? Yeah your idea is much better, Just rma that pos and grab a stronger fortron.

Edit: Dont bother with psu tester. Those are also a pos equipment for testing a defective psu

they usually are just a thing to short pin 14 to ground and have an LED on like the 3.3v rail to show that its on.

try unplugging everytihng and jumping pin 14 to ground.

Yeah, thats what I did, no go.
So its an RMA I guess, that ruins my weekend.
Ahhh the joys of yelling at computer parts

It's alright MrSuasher , At least your getting a new one in return from this P.O.S that's giving you a lot of hassles from using your rig

My friend had this same problem, what we did was unplug everything unnecessary and it booted up fine. His final solution, until he gets a new one, is to hit the power button and plug his x800pro in very quickly. While I would not have recomended this, it works for him.

i had the same problem for 6 or 7 ECS boards. it wasnt the PS for me, once i put in a gigabyte, it booted up no problem.

but mine would turn on, i just had to sit there turning on and off the PS and hitting the power button about 20 times and it would start.

the store had a bad batch of ECS boards i guess. or maybe all ECS boards are bad
