Buggered PSU?

Wiry · 10 May 2011 at 20:38

Ok, I have this problem where sometimes, I can hear a high pitched noise from my computer and also I can sometimes hear an annoying noise and I am lead to believe that the PSU and FAN has gone! I am prepared to buy a new one, but not for the sake of it! Has anyone heard this problem before?

Does the sound go away when you force Vsync ON in the graphics card driver settings?

You think the PSU fan is dead? There's a simple and effective test. Put your hand near it.

Have you confirmed that the PSU is where the noise comes from?

I am not sure what you mean buy this, but the high pitched noise only appears when I do the odd things

All I know is that it is coming from around the PSU/Graphics area, at the bottom left of my HAF X

Newish Nvidia cards for example are notorious for making screaming sounds called coil whine, force vsync on seems to have an effect on it.

Why dont you spend 20 seconds turning Vsync on in the display driver even if its a ATI card?

ok, how do I try it! I'm a novice to this sort of tech

You will find the setting within the Catalyst control center somewhere, there maybe three options,

Force Vsync OFF
Force Vsync ON
Application controlled.

Ok, Cheers for the reply, but I was another website, and I have found out the problem! lol, Its because the framerate is too high apparently, I was starting "Minecraft" and the framerate was on 400, so I enabled "limit framerate", Cheers for the help anyway! Also, what do you guys reckon to this

Compared to a Corsair Modular AX1200 power supply for example! As I am thinking of getting a new PSU as mine is pretty much dead, and it's not a very good brand, "Generic" if you'd like to call it! So I thought I'd have a look on here at PSU's and saw the OCZ ZX

Vsync limits the frame rate to the monitors refresh rate, so it will be locked at 60fps for example.

Just move the slider all the way to the right, and then click apply.

Wiry, 'limit framerate' is technically known as 'vSync' which is exactly what Stulid asked you to check.

Ummm, you trying to power the whole street?

if you can list some specs of the pc, maybe you/we will discover a PSU thats a little easier on the purse strings?

Wiry · 10 May 2011 at 21:31

oh lol, here is my specs mate;

Intel i5 750
p55 4 pin mobo
3 sata 2 drives
2 dvd/blu ray reader drives
watercooling with 120mm rad
and about 4 200mm fans that are red led and one 120mm for rad
2 sticks of ddr3 sdram
5850, soon to be crossfired

I want the PSU to be future proof and I have my PC on about 12 hours per day

stulid · 10 May 2011 at 21:34

750w is more than enough, including crossfire.

Am I right in saying that I have heard problems with those supplies..

"There's a lot of complaints about the annoying buzzing noise the modular XFX PSU's make... so if you don't like noise I would avoid them."

I don't want to buy one of these and my pc isn't quiet and is making unusual noises! Also, the higher the efficiency, the better!
