Power Supply Advice Needed

post #1 of 5
Thread Starter 
Hey,
I posted a few days ago, when i thought i'd damaged my XFX 450w PSU from overclocking too highly on the system in my sig. It was making a sound which didn't sound right and Shilka and a couple of others recommended me to get a higher powered one and RMA the old one. Now i thought when a PSU was dead/dying it would power off the system, but that never happened it just made an electrical buzzing/sizzling sound which i thought was the power supply (put my ear next to it) and after i removed it i saw it had been pulling a load of dust into the filters which makes me think it was getting hot and ramping the fan up.

So i got a new PSU delivered yesterday (XFX 650w for future upgrades) and although the sizzling sound is gone there is still a motherboard buzz, which i assume is from stressing a mobo out on Prime95 on heavy OC. What i wanted to know, if it would be worth me either quit overclocking or ramp it down and use the 450w before it gets RMA'ed or just send the thing back. The reason i ask is because the retailer will charge if they don't find anything wrong with it.

Any thoughts?
Geoff

Wow...the rig in your sig on a 450watt was asking quite a lot out of your hardware...AMD FX are not exactly energy efficient on load...in any case, the buzzing is most likely electrical buzz from your motherboards VRM. Low end boards do this. It shouldn't be something to worry about. Although you shouldn't have used a 450watt PSU anyway, I'd keep the 650, return the 450, and if the noise bothers you, relax the overclock.

It was probably coil whine you experienced, the PSU is probably fine if not being stressed. I did not see such thread so IDK.

I usually get a bit of flamage for telling people not to overclock, it's a little too Vin-Diesel.

Take me for example, had an AMD 4170, rather then spend money cooling, dealing with bluescreens, screeching PSUs, keeping algae out and maintaining leaks, RMA fraud for perfectly fine in-spec parts in some lame search for a better in-spec part etc - I just bought a better computer, lol. loafs along @30 on air, dead quiet, nothing is stressed and no degradation to the CPU.

In my opinion performance computers are judged on stability first.

Yeah they are massive power hogs, and that does make sense its not a high end board by any stretch. Thats good i was worried that the motherboard was damaged or something but there definatly was a buzzing from the PSU too. I think i will stick with the 650w and possibly upgrade the motherboard in a few months time thumb.gif

I agree, it would be nicer to get higher performing gear out of the box with the stability and power consumption that makes it bang for buck, but as far as my OC goes i think i have the hang of it. I'm not sure if i've won the silicon lottery on this CPU but its not BSOD for weeks and the heat tops out on high 30's on 4.1GHz. As for the degredation im not one who keeps hardware for years anyhow, so it's not a big deal but i'll learn if one goes bang wink.gif

Thanks for the help guys, was only a small thing but a load off my mind thumb.gif
