I've just bought a brand new PC over the internet & I think the supplier is going out of business as he won't return my calls or emails.
I'm having problems with it as it keeps rebooting & tells me it is shutting down to protect itself due to voltage overload issues.
Boot message is:
Power supply surges detected during the previous power on. ASUS anti surge was triggered to protect system from unstable power supply unit.
I've attached a Speccy doc giving details of the voltages involved. Some look a bit low & others look high (12v when it should be 5v?) so perhaps this is the problem. It's just plugged into the mains with no anti spike/surge or UPS.
Can anyone tell me if I need a new power supply?
Many thanks
Paul

Did you make any changes to BIOS settings/overclocking? Sounds like a faulty power supply which could be best swapping it out with a greater or equal wattage.

It was overclocked by 10% at the time it started going wrong. As this was a standard BIOS option I didn't think it could do any harm.
Perhaps my supplier underspecced the PSU to save more money.
Did the Speccy voltage figures look wrong to you?
Actually, aren't the -5v & -12v figures the wrong way round? Could it be wired wrongly?
Thanks.

its a faulty power supply.

CPU CORE 1.008 V
MEMORY CONTROLLER 1.644 V
+3.3V 1.872 V
+5V 3.427 V
+12V 7.968 V
-12V -3.120 V
-5V -12.000 V
+5V HIGH THRESHOLD 5.000 V
Yes I would check the Power supply manually here because your status on psu is very unhappy.

http://pcsupport.about.com/od/insidethepc/a/power-supply-voltage-tolerance.htm


We cannot rely on the software very much because its not very correct

To test the PSU you need a multi-netter amd a load. (with the power on) test each pair (http://pcsupport.about.com/od/toolsofthetrade/ht/power-supply-test-multimeter.htm) and compared it to the sticker.

or easy way is replace it with CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply -89.99

Thanks very much for confirming what I expected.
I'm threatening my supplier with legal action unless he refunds me, so hopefully it will become his problem.
If I end up keeping the PC, at least I know what's wrong with it.

Your welcome

all you have to do is simply replace the PSU because you computer shutdown as a fail-safe measure you can OC on that psu I link above.

If you are located in the US does the little red switch on the back of the PSU say 115v or 220v?

US it needs to be at 115v
EU it needs to be at 220v

There's no switch to change & it worked for a week until failing so I don't think that's it.
Thanks for the suggestion though.

It may well be that your power supply is just not working anymore.
