Antec HCG-750 noise problems?

I've just assembled my rig yesterday and everything seemed fine until my (sensitive apparently) ears started hearing something coming out of the rig. It's no superloud coil whine or anything, but it's audible. I found out it seems to be coming from the PSU. It's a faint electrical sound and I noticed it increasing when I pushed on the top of the psu (fan faced down). I pulled it out and placed my ear onto it and it was quite annoying

Is this normal? I also noticed some kind of static noise/buzzing coming from the I/O panel, or atleast that section of the computer.

I checked the PSU and I found the noise is a combination of a faint electrical sound coming out of the components and the fan making a slight sound. Like it's hitting something, but that's impossible since I took it out of the PSU.

That's an odd problem that you have there. Please create a ticket on our website, please go to

From that buzzing sound, it sounds like more of a electrical issue, it could be an early sign that the charging capacitors might be going bad but just to be safe, let's RMA your power supply.

Thanks

I think that's impossible now. Made a slight error. To get the fan out, I had to unscrew the panel. The last screw felt a little weird and only after did I find out it was a sticker. Pretty sure it was the warranty sticker then frown.gif
