Colorsit 550W failing or just plain rubbish?

[chiller]

Hi All,

have the above powersupply in a system with an overclocked Q6600 AT 3.3ghz. It works fine but after 15 minutes or so of stress testing the power supply starts a low pitched whistle, is this something to be concerned about ... is it failing or struggling to cope with the load? The whistling stops the moment i stop PRIME95. It has a single 12v rail with 30a capacity and is roughly 4-5 years old.

Any advice is greatly appreciated

Thanks

I would hazard that your PSU is on it's way out. Replace it before it pops more than just itself!

Meh, could just be the fan bearings or somesuch. Defo coming from the PSU? I would say that (esp for a brand ive never heard of!) its doing well to last 5 years running an OC'd modern proc so i'd be tempted to replace it anyway.

I would tend to agree.
Your PSU could very well be in the process of failing and you should consider replacing it before it damages anything else.

Its probably both
Rubbish and now its also failing...
They generally go hand in hand

Take a look at my sig for some psu reviews.

Thanks for the responses guys,

thought as much - will buy a new power supply before I kill my pc. I am thinking of getting a Corsair 650TX ... and afte reading Silverion77 link to the 850TX review it should be good. Will a better power supply improve my Vdroop or is this exclusively a motherboard issue?

vdrop and droop are usually related to the motherboard.

I mean more stable volts on the PSU end helps, but i too with my Signature (or other high end PSUs) still get it
