power supply making squeaky/scratchy noises

[naimcohen]

Hello all

I have an intel i7 920 processor and when the multiplier is at 21 there is a squeaky/scratchy noise coming from the psu.

The psu is a corsair TX650w

the rest of the system is:

Gigabyte ex58-ud3r
Ocz gold 6gb ram pcs-12800mhz
Asus en9500gt

before i bought the corsair psu i had it running on an antec neo 500 watt power supply and it would also make the noises so i was advised to get the power supply i have now.

Could it just be this psu is faulty? when the multiplier is at 12 or 15 there are no noises but at 21 there is a noise. I am using cpuz to see what the current multiplier is.

any help will be appreciated

Thanks

Are you sure its from the PSU and not the motherboard or GPU? It may even be the CPU cooling fan.

1000% sure its the psu

after much searching i found the problem and other people did have it. I just had to disable a setting in the bios: C1E and EIST (Enhanced Intel Speedstep Technology) to disable in the MB BIOS.

and the problem went away

its a shame it took so long and many of the computer retailers just kept telling me to buy a new power supply
