tewky Posted October 1, 2007 Share Posted October 1, 2007 When I turn on the PC (from the power button on the case) I get a strange noise coming from my HX450. It only lasts for one (1) second but it sounds like a squealing/grinding noise. I am worried about this because just recently I had a 160GB Maxtor suddenly cease to work on me. I was getting a BIOS alarm followed by a nasty grinding noise...never had any problems before this PSU so I am a little suspicious of it. If there is something wrong with this PSU and it wrecks my new Seagate 250gb there will be hell to pay. Any ideas on why I am getting this grinding/squealing noise on startup (the exact second I push the power button)? It is definitely coming from the PSU, I checked and double checked.

Corsair Employees RAM GUY Posted October 1, 2007 Corsair Employees Share Posted October 1, 2007 Do you have the PSU plugged into a backup UPS or a surge protector? If so, I would see if it does the same thing when plugged directly into a wall outlet. Link to comment Share on other sites More sharing options...
tewky Posted October 2, 2007 Author Share Posted October 2, 2007 Never mind. I took apart my case and disabled every fan one by one to see what was up, because I suspected it could be a fan. Turned out to be a little 60mm case fan I have venting from the top of my PC above and a little to the side of the power supply. I guess my ears aren't good enough to detect sounds in that small of a distance. Link to comment Share on other sites More sharing options...
