My PSU is making weird popping noise.

post #1 of 7
Thread Starter 
My XFX 450W PSU is making weird popping noise. The noise increases when I'm playing games or doing 3D rendering. What could be causing this? Is it safe to use the PC?


My PC rig
Intel 3770K 3.5Ghz
16GB XMS 3 Corsair Ram
Sapphire AMD HD 7950 3GB
ASUS P8Z77-V motherboard
Samsung SSD 128GB
2TB Seagate HDD
Samsung Blu Ray drive.


I recorded on my Microsoft Surface and uploaded on YouTube.

hmm well with ur PC setup i would say you should run at least a 600W for peace of mind, also that noise almost sounds like a zip tie or piece of debris got caught into the fan. so like i said i would upgrade to be safe, or pop it open and see whats going on that's always the fun thing to do. thumb.gif

yea if you leave it plugged in.... i would hope most people have the common sense of pulling the plug before opening a PSU

I think your PSU may not be enough for your system or something may be wrong with it. 450W does seem cutting it a little close to me.

Plugged in or not the capacitors easily hold enough of a charge to kill you if you touch them. Unless you're going to drain your caps first, you shouldn't be poking around the inside of a PSU.

Primary caps on small PSUs (other words : at least have some sort of PFC) are pretty small that they discharge rather quickly after you turn the power off

Secondary caps don't even matter at all though

Hmm ... Popping noise, anyone thought of popping caps?
