Problem with newly built Pc!

[SaMB]

Hey,

I recently bought a:

Foxconn Socket 775 Intel 64-bit Motherboard,
Intel Pentium D 925 Dual Core Socket 775 Processor,
2 x 1GB DDR2 667 Memory,
ATX 12V 450 watts power supply,

I connected these wires together and put on the CPU fan and heatsink, i then found out there was a 8pin power connector on the motherboard when the PSU only gives a 4pin, i read on other forums that this doesnt matter and it should still work plugged into the 8pin.

So i plugged in the 4pin into the the 8pin connector, and thought i was ready to start it up to test the fans etc, as soon as i turned the power on without pushing the power button on the case, a small red light appeared on the motherboard, just next to the 24pin connector.

I then tried pushing the case power button, nothing happened, the red light just stayed lit, not even the cpu fan turned on!

Any idea on whats wrong? any help would be greatly appreciated

What brand power supply are you using?

Is it a ATX 2.0 or higher power supply?

Is the motherboard in the case or do you have it out of the case on a non-conductive surface?

I have put the motherboard inside of the case, the brand is win power i think, and its model 450.

How do i check if its a ATX 2.0 or higher power supply?

Does it have a 24 pin motherboard power connector and at least one square 4 pin 12v power connector?

If it's a Win power supply you should consider changing it for something better...Win power supplies are rubbish. Check out this thread.

Yes it has a 24pin, and a 4pin power connector, but the motherboard has a 8pin connector, does this make a difference? or where i plug in the 4pin?

And thanks for the advice il test it with another PSU, is there a possibility any thing else is corrupt like the motherboard, or is it most likely the PSU?

Looking at your parts list the thing that sticks out is the power supply...it's a cheap low quality unit and the most likely thing to be DOA or defective.

If the computer does boot up okay with another power supply then you've found the problem, but if computer doesn't boot up then something else may be DOA or defective.
