silverstone SFX PSU and rebuild help

post #1 of 4
Thread Starter 
I've been noticing some real high pitch chirping when the PC was under loads and initially thought it was my gpu and cooler (560 TI/h60 corsair) however after exchanging the cpu cooler to my stock intel cooler, the chirping was not gone which only leaves the PSU.


I just decided I would buy myself another case and had my eye open for the itx cases that uses standard atx PSU's. The problem with this is that I don't own a modular so am worried that might be an issue in managing the space.

I was looking at the LIAN LI PC-Q25B and the LIAN LI PC-Q08B.

Which one of these can accommodate both nonmodular psu and the H60? thanks


EDIT

crap I think I have spoken too soon. it might be my 560 ti. I just took off the card and tried to run the same load just using the intergrated gpu and did not hear any beeps.


How can I further test this? I do have another GPU 4850 but it doesnt push the same watt as the 560 so it can be inconclusive.


EDIT2


Holy thats so annoying. it was the 560ti after all.


I first tested 4860 and decide to try the system with 560 only tthis time, change the psu.


does all 560 ti make this kinda noise?

would still like to change the case because sg05 feels very flimsy for its price

Known issue. It's not the GPU it's something to do with how the motherboard routes some of the current. If your ST45SF is chirping, and it has a white label marked "V1.1", then you can get a replacement "V2.0" from Silverstone to fix this problem.

See this thread on [H] for more details.

Well, it could be the GPU or the PSU, because both are known to make noises. You should run your stuff outside the case to narrow down the noise by stretching the PSU cables so it sits as far away as possible from the graphics card. That should make it easier to distinguish between the two, noise-wise.

I see... I wouldve thought theyd put the revisioned psu by now, that post seems to be a few months old.

I did not do an accurate test, however I did change the psu to a gamexstream ocz atx psu and still made the ringing noise so I just assumed it was my psu.

I have my 4850 in right now and it isnt making any annoying noise when under load however the power consumption on this is far less than that of a 560 ti so it can be the psu.

to prevent this, think i should get a 6950 instead? i heard it does draw less than the ti



I have also ran prime95 with furmark and does not produce the noise. I think it is safe to say it was my gpu this time around
