Default Problem with my thermaltake TPG-750

My PSU, TPG-750 is making a light whining sound, and it gets louder when I put stress on it. But even weirder is that if I scroll up and down a webpage or a pdf document, the whine is completely in sync with each movement of my mousewheel. Has anyone ever experienced this before with a PSU? I am 100% sure its coming from the PSU and not the video card or case fans.

The noise can only be heard in a silent room, but at night is very noticeable. Is it possible to lube PSU fan with sewing machine oil or similar?

Thanks for the help

Default Solved

I switched the 2 PCI-E GPU power connectors into the other 2 PCI-E GPU modular power sockets that the PSU has, and now it is completely silent. Problem solved.......unless I go with SLI down the road

This seems like a weird problem, and one a PSU shouldn't have, but the PSU is completely silent now so it saved me an rma. Why a power socket should whine and not the fan is beyond my pay grade. but i had a feeling it was something to do with the video because it got louder the more video stress was put on the PSU

What you have there is a finickey set of Coils on one of the rails.
Since its a multi Rail design you literally swapped over and put the load on a whole different power set inside of the PSU. A set that obviously doesn't have the small flaw that created the noise in the first place.

Coil while which is what it usually is, is a common occurance.

Thanks, at least now I know whats up. It's not worth the rma since I dont have plans for SLI, and I dont want to be w/o the use of PC for an extended period. Disappointing though, the PSU wasn't cheap....

Toughpower Grand features 105℃/221℉ Japanese made electrolytic capacitors & solid State capacitors with low ESR, which greatly improves the durability and offers the highest stability and reliability."

The fan is pretty silent though, and it does look good inside the case, w/ led's

Thermaltake was great, they are sending a replacement before I have return the one I have. They also said its rare but does occur in the capacitor, and should replace because it will get worse over time.

Thanks for the help.

Default Update

Thermaltake has done me so right, I thought I would post it.

They offered to send me a brand new TPG-850M to replace my 750M since they do not have any new stock on hand. I don't even have to return my PSU until I get the new one. This is going above and beyond, especially since my PSU is working fine under my current configuration, and I never even asked for a replacement or an rma. Thermaltake has also responded to all of my emails within hours not days.

I would never have dreamed this level of customer service from just an inquiry I made about a whine, that I no longer can hear, and they deserve all the kudos possible. The TPG-850M gets great reviews and retails for about $50 more than the 750M did.

Newegg.com - Thermaltake Toughpower Grand TPG-850M 850W ATX 12V v2.3 & SSI EPS 12V v2.92 SLI Certified CrossFire Certified 80 PLUS GOLD Certified Active PFC Power Supply

If in the market for a PSU, I would consider a Thermaltake based on their customer service alone, but also a 7 year warranty with their PSU's. My 750 is near silent, looks great and built like a brick!! I would buy it again.

Score!, love customer service, hell I'll pay more for a product just because of an experience like this one, and then there is Gigabyte... you don't even want to know.
