Faulty CPU please confirm?

[Beedy555]

Hi,

When i remove the ATX12V1 cables for CPU1 & CPU2 my computer boots fine

When these cables are attached the computer will only power on for a second then switch off

i wanted to be sure that the problem is related to my CPU specifically, and that this is the cause?

Thankyou

Let me try and understand this. When no power is attached to the CPU, the computer boots fine?

i'm assuming 24pin only is ok.

Hi, thanks for the reply, yes that is correct when the power cables from the PSU named "CPU1" and "CPU2" are not attached into the ATX12V1 port the PC boots fine, i have been trying to toubleshoot this for a while now, and i wanted to know if this is related to the PSU or the CPU? thanks again

or perhaps the PSU is not producing enough power to POST with the cables attached? and therefore faulty

Sounds like a PSU issue. CPUs almost never go bad.

Do you have another known good PSU to try out with? If not, go with a Corsair HX series (Modular) PSU; 650 or 750 watts. I have the HX-850 and am very satisfied; running for about 2 years now. 12 hours a day on the average.

Hey, thanks for your reply. I'm quite confident this is a PSU issue now, although i did test the current PSU on another PC and it powered on, but that was a lower spec machine, another thing to mention is that the power surges when the PSU is running as if it varies from time to time.

thanks for links, i'm in the UK so i normally use http://www.overclockers.co.uk

If the PSU power surges under use, definitely the PSU is bad. Replace right away.

Use the Newegg links as a reference. I like Corsair's Modular series PSUs.
