Power Supply dead? How to test?

[EtheAv8r]

I have a problem with my daughter’s PC – last time it was used OK at the end of the session it would not shut-down, a shut-down command always resulted it a re-start. So I forced it to power-off by pressing in and holding the power-on button on the case.

Next day it would not power on – the led on the motherboard briefly lit and went out. So I probably have a PSU fault or a motherboard fault.

Is there a simple way to force the PSU to power on if not connected to the motherboard so I can test it / check if there is any life with a voltmeter?

Yes.

The green pin (about the 4th one in and the only green one) and any of the blacks next to it, get a paperclip and put it in both of the pins, you can then use the switch on the back of the psu as a start stop switch. It is best to connect at least one thing that uses power, like a fan controller and some fans etc.

Thanks Clunk - I had a private bet with myself that you would be in there with a solution!

How is the sad tale of the Commando going?

[Clunk]

Dunno about the commando, scan got it back last thursday and it's still showing as not received, I rang up and they said they have a huge backlog of rma's, so I got them to put that as a refund instead of replacement and I ordered another, but it says no delivery until friday

As a positive, the second replacement psu is coming tomorrow from enermax

Is your psu buggered then?

[EtheAv8r]

I will test her PSU tomorrow - she has gone to bed - as must I - up at 06:00 for work....

Touch wood - my Commando is good.... back to stock at moment as I only have it and an old Shuttle alive in the house at present....

[Clunk]

Careful with it then, good luck

The 'dead' PSU is an Antec TruePower 380SP that came with an Antec Sonata case about 3.5 years ago.... it is not a new one and has given a lot of service. I think it died gently, and just passed away in it's sleep.....

[Clunk]

As long as it didnt suffer, thats the "mains" thing.

An Antec 430 TruePower I bought about 4 years ago gave up with a bang. Other parts were ok (thank God).
