PSU Failed

MachTwo · 24 Apr 2012 at 07:57

Hi all -

My PSU has died this morning, an Enermax 620W. The computer won't turn on - though the motherboard power/reset lights are illuminated.

I've had no errors with the system, no crashes or hardware failure reports. My guess is that the PSU has failed...

Does anyone have any recommendations for a good PSU? I'm a software developer and use my desktop extensively. XFX ProSeries 850W?

Many thanks.

XFX Pro 450W '80 Plus Bronze' is a brilliant one, it's also available in 550W and up to 850W but I think you'll only need 450, maybe 550.

Hi there

May I suggest before you jump into buying a new PSU that you try this troubleshooting thread. Particularly “How to check if your PSU is working” as if you have lights on the motherboard that implies there is power getting to the system.

Do the fans spin up when you try to turn it on?

Thanks for the replies -

No fans spin up at all. I do agree it's odd that the mobo has power, but I assumed this was 12v DC comming off the PSU.

I'll pick up the XFX in my way home tonight but test my existing PSU first using the link above. I'm hoping it's a fault with the PSU and not the mobo.

Same goes for your MOBO, is it still under warranty, it'll be needed in a worst case scenario.

I replaced the PSU, but the same thing is happening. Power trips as soon as I press the power button. Reset CMOS, took everything out apart from the CPU. So I think it's a fault with the mobo.

I've ordered a new Z68 board and i7 2600

I'd take everything out of your case, reset the CMOS and try booting with just the basics, put the motherboard on top of your motherboard cardboard box and test it on that.

Could be shorting out in the case somewhere.

I would also have tested the PSU first by taking it out and doing the paperclip test

Enjoy your new board though!
