Has my PSU had it??

Hi just lately my computer will not turn on!

When I press the power button the computer will turn on for one second and then shut itself down.

All the case fans spin, the PSU fan spins, the lights on the front of the case light up but then the computer shuts down.

Is this a case of a new PSU?

I would just like to confirm before I spend the money on a new one.
 
Yeah it sounds like it, have you checked to see if everything is connected and have you tried a different PSU?
 
I have checked and everything is still connected but I do not have another power supply available. Is there any other way to confirm that the PSU is at fault?
 
this happened to me also... my fix was because my cpu fan was not on tight... its def not overheating?
 
Well I cannot check if it is overheating because after 1 second of turning it on the computer shuts itself down.

All cables and connections seem to be in place
 
Not yet, Im going to order a power supply but still unsure as to which one. It has to be a budget one (around £20) and be enough to power the system. It is not the one in my signature, here are the specs:

Gigabyte GA M57SLI-S4 SKT AM2 Nvidia MCP55P PCI-E 8Channel audio ATX
AMD Athlon 64 X2 4800+ (2.5GHz) Socket AM2 Energy Efficient L2 1MB (2x512KB)
Crucial 1GB 240-PIN DIMM UNBUFF DDR2 PC5300
Western Digital WD2500KS 250GB 7200RPM SATAII/300 16MB Cache Hard Drive - OEM
BFG 7600GT 256mb GDDR3 Dual DVI PCI-E
NEC AD-5170A-0B 18xDVD±RW DL Black - Bare Drive

The old PSU was just one that came with the case so no wonder its no good. (500W)

This is the PSU I am looking at:

I know it's cheap and very standard but It's 500W and should do the same job as the previous one. The only thing that has got me thinking is that it is a 20+4 pin and not a 4 and 20+4 pin. Is this enough do you think or should I invest further?

I am now quite sure that it is the PSU at fault because I have removed all leads and plugged them back in and still the same problem occurs, nothing is shorting the board and I am sure nothing is overheaing.

If it turns itself off there's an obvious problem with the power so maybe it is the PSU.

I'm thinking of getting the same PSU from ebuyer. Seems to be popular. 500W. Where can you go wrong?
 
It was infact the PSU at fault, I replaced it with a standard 500W PSU and it works a dream. Very quiet also.

Thanks for the support again.

Had same thing happen on one of my other computers. Worked in other computers fine. Disconnected the 12V 4pin, worked like a charm. :cool:
