Spec me a new PSU

[mogwai]

Currently I have a Corsair HX750w but this seems to be having issues. These being when the pc is just sitting there and switched off I can hear a high pitched buzzing sound coming from the PSU. It make a loud click sound during post and twice more when the starting Windows 7 animation is on screen.

I don't really want to be without it over christmas so what would you guys recommend as replacement? I will then look at RMA'ing my current to corsair in the new year and keep it as a spare.

• Intel Core i7 2600k
• Asus P8P67 Deluxe
• 6 Gb Corsair 1600 Mhz RAM
• Asus GTX570 Direct CU II
• Intel 510 250 Gb SSD
• Western Digital Blue 1Tb
• LG BLuray reader dvd burner
• Asus Xonar DX PCi-e

XFX Pro 850W Core Edition '80 Plus Bronze' Power Supply £79.98 on the new This Week Only deals.

Plenty for SLI in the future if needed.

You can spend less if you only need something for your current setup.

Edit

See below.

It's not on the new This Week Only.

do you have 6gb or 8gb ram(not that it has any bearing on the psu)?

a decent 500w psu will suffice, how much are you looking to spend?

tho may get away with http://www.overclockers.co.uk/showproduct.php?prodid=CA-007-XF&groupid=701&catid=123&subcat=

I currently have 2 sticks of DD3 1600 mhz giving me 8 gb. My only requirements are that it is modular and as quiet as possible. Also hopefully doesn't also suffer with the issues that this current Corsair one seems to have.

I won't be looking to SLi or anythings as the cooler on my current 570 is a triple height one.

I currently have 3 sticks of DD3 1600 mhz giving me 6 gb.

Just as an aside then you should be using 2 or 4 sticks for proper dual channel operation.

I assumed your sig. was correct and that what you typed in the first post was a mistake.

I have just checked again and it is 2 sticks. I got mixed up with the other rig I have which is a triple channel setup.

Fair enough.

PSU's then:

Antec TruePower New Modular 550W '80 Plus Bronze' Power Supply £69.98

OCZ ZT 550W '80 Plus Bronze' Modular Power Supply £69.98

Something a little better so there's less strain on the PSU:

Antec TruePower New Modular 650W '80 Plus Bronze' Power Supply £72.98

If you are after a psu that is the same wattage as your current one then I would suggest this

I am happy to drop down from 750 w. But would like it to have sufficient headroom so that it is still quiet.

A New HX750 would cost around £125.

At around the same price £122 you coud get a BeQuiet Dark Power Pro P9 650W '80 Plus Gold' Modular Power Supply. Now you know you are getting a quiet power supply.

I did some testing last night and it seems to be the PSU at fault with what I assume is coil whine. As I unplugged the power from the motherboard and GPU and while it lessend the noise it was still present (this while the pc is powered off).

I think I have narrowed it down to 2 and I am not sure which one to go for.

The OCZ ZT 750w

XFX 750 XXX Black

Where available I may get the 650w version if available.

Ive used two of the cheaper corsair PSU's in builds this month. Both of them emitted a high pitch noise. I have super sensitive hearing it was bairly audiable to others. Corsair should look into it because its defiently there though. Frustrating because i like their psu's.

I think the fact you have super sensitive hearing is the problem not Corsair PSU's.
