Corsair 650W power supply whining

it's recently come to my attention that my corsair power supply is whining/buzzing in an ungodly, super high frequency way... the kind of high frequency that i won't be able to hear in 10 years if i'm so lucky. i confirmed this with my ear ringing after being next to the power supply unit, but not ringing while next to everything else in my case that can be considered a "unit."

my system only has three set of fans (power supply fan, CPU fans, graphics card fans). i've set the ones i control with software to zero and stopped the PSU fan with my finger, and the buzzing persists. also, when i switch from "high performance" to "balanced", the buzzing goes from solid to intermittent as the processor clocks up or devices consume power (e.g. mouse moving) thumb.gif
i've cycled the power supply, moved the computer off the UPS, tried different outlets, and unplugged my only remaining non-SSD drive, all with the same results. unfortunately, the buzzing is so fiesty that it's propagating through my PCI sound card and into my speakers, which repeat the terribly high frequency noise. still audible when using a USB sound card; not audible when signal cable is unplugged from computer.

i guess i have three four questions for this topic.
1) what makes the actual noise, in super technical speak?
2) why has this underutilized seasonic unit failed me after 1.5 short years?
3) how do i avoid this noisy menace in the future?
4) why do i continue to pour money into computer components that don't respect me

In answer to your questions:

1) not quite sure if I'm honest although the corsair hx series has a 7 year warranty (or minimum 5) so I'd strongly suggest RMAing it. Maybe contact their forums p, they've got pretty good customer service.

2) unfortunately that's the way with components, not all have the lifespan of a cat/dog so one is bound to go here or there. Also depends on how intense you use your rig. Tephen again you may have been unlucky and got a dodgy batch.

3) it's not to etching you can avoid. If your PSU is faulty then you either RMA (if still under warranty) or buy a new one.

4) haha, you're not the only one. wink.gif I bought a 700w Mushkin joule psu, brand new and it was making the same noise you're describing. Although when I requested RMA it was refused because it had been opened- which was REALLY ANNOYING - but these things just happen.

Hope this helps you out dude smile.gif

bah, i never used over maybe 575 watts of it i bet.

it's funny you should bring up voiding the warranty by opening it up, because that's definitely the first thing i did.

the scam PSU makers have going really is ingenious: give a multi-year warranty (void upon removal of a certain screw) but put a 200 decibel small aircraft engine that's "thermally controlled" on the inside. in this phrasing, "thermally controlled" for the fan means "40 CFM greater than it needs to be at all times," in my experience.

que sera, sera, i guess. time to order a new one. thanks for the help... glad to hear you've had power supply woes as well. misery loves company wink.gif
