ryan251 Posted October 20, 2008 Share Posted October 20, 2008 I built my new PC with a CMPSU-450VX power supply. It is silent, except for disk activity - when reading or writing large files, a very loud whine comes from power supply, I can only describe it as a high pitch whine / squeal "noise". It only happens during disk activity, and I am sure the sound is coming from the power supply (and not the disks, or motherboard, etc). I bought this power supply because it won awards for being quiet... I can't RMA it with newegg, because I already sent in the UPC for rebate. Questions: 1 - Can I return this power supply to Corsair for a replacement? 2 - Will I be sent a new one unit, or a refurbished (recertifed) one? 3 - Do I have to pay to ship it to Corsair?
