psu squealing! silverstone strider 850w gold

post #1 of 12
Thread Starter 
Hi there,

In my previous case, corsair 600t se, my psu (silverstone strider 850w gold) was silent in normal operation. since i installed it into my new case last night, silverstone ft02, the psu has a constant squeak/squeal while idling. i haven't tried loading it yet, but is there anything i can do to make the sound go away. i tipped the case over so the psu sits horizontally and the squeal goes away. only when it's 90 degrees rotated does it make the sound.

help please!

Would the orientation of the PSU make the difference between silence and squealing, though, if it were coil whine? I would have to guess that it's the fan bearing, it may not like a sideways orientation or may be wearing prematurely, but I'm not sure if it would make the noise the OP is describing.

I'd be getting it replaced. It should not be doing that. The last thing you want is your PSU blowing up, potentially frying the rest of the system in the process. $200 now or $2000 later.

yea it's definitely the psu fan. i disconnected every fan to isolate the sound and it's the psu. i think it may be the bearing like broken projector implied. do you guys think it would be easy to buy another fan and swap it out? or would this be a case of rma?

"Squeeling" sound's like coil whine, which you should RMA.

If it's the fan, sure, but you probably void your 3 year warranty. That's kind of a small warranty considering most PSU's are 5-7 years.

Is there a high pitched beep along side the fan noise? hard to describe..

RMA. Better to play it safe in my opinion.

I took apart the psu and applied some silicone lube to the bearing. the bugger still sounds like it's going to die any minute now... Ended up just ordering a corsair ax750. Seeing as how the fan doesn't even turn on until it's needed it should really help with keeping my system quiet. My question is, will the 750 be enough? I'm planning to add a water cooling loop to the rig later on as well as upgrade the card once keplar is out.

Current specs:
i5 2500K @ 4.5ghz
gtx 570
1 ssd + 1 hdd
1 optical drive
4 fans
fan controller

Coils or *****ty caps. Either one, send it off. Not exceptable on a power supply and i definitely wouldn't risk it. Especially if it is a capacitor.

Btw, what power supply is it? Name and shame oops, re-read the op

yeah the ax750 is easily enough

on a side note, the fan that comes with the STx50+ psus (young lin tech i believe) is supposedly really quiet, being rated at 22db at max speed. any owners confirm or deny this?
