PSU that helps with coil whine

Chrisoldinho · 27 Jul 2012 at 16:24

Not sure how much difference this makes but I understand the Silverstone Gold series PSU's have capacitors that help reduce the effects of coil whine.

Has anyone had experience with this PSU or similar offerings, and do they make a notable difference?

Thanks,
Chris.

I had a Be Quiet Dark Power Pro P8 PSU which generated coil whine under low load situations which is the worst imo as you can hear it quite well as the PC is relatively quiet. I put up with this for a year or so and RMA it back to Be quiet in Germany. They have replaced it with a new 1000W P8 PSU within a week. I wouldn't think that coil whine is a typical and common problem for PSU's, but I'm not sure on this.

I didn't really explain myself properly in my OP. Basically, my GPU emits a buzzing noise, I hear certain PSU's have capacitors either on the PCI-E cables or internally in the PSU to assist with reducing coil whine and wondered if anyone had any experience of the effects, or if it just a marketing gimmick.

it can be just down to luck,high end psu's cause/dont cause the noise just as much as a cheapo,can also be motherboard or graphic card thats the cause or a combination

it might help having suppressors built into the pci/e plugs

you are right i misunderstood what you after...i never heard about special PSU features which could help to mitigate GPU coil whine, wouldn't really understand how that is supposed to work.

Things like:-

2200uF 16V electrolytic capacitor connected between +12V and ground on the PCI-E cable to assist reducing the noise associated with coil whine.

Just wondered if anyone had any experience of using such PSU's, and the effects, positive or useless
