Hi,
I bought a Corsair HX620W back in May 2008. Around July my 3.3V rail began to drop, causing instability and forcing me to RMA the PSU. I received a new PSU a few weeks later, installed it with no problems, and have until recently been perfectly happy with it.
In the last couple of weeks I've purchased a second-hand 7600GS, which at first ran with no problems at all. It was a nice step up from my old GeForce2.
However, a few days ago I began to get stability problems, with random BSODs and occasional restarting. At first I thought it was the new card, and updated DirectX and the gfx drivers (to 94.24, recommended as the best for the 7600GS on the NVidia forums), but it didn't help. The crashes became more frequent, and now included the monitor turning off by itself - I could only turn it back on by restarting the computer.
Still thinking the problem was the card, I reinstalled my old GF2, which has been ultra-reliable for years. No joy - still the crashes, restarting, and monitor shutting off. And in addition the computer would occasionally lock up, requiring another restart. On a whim I checked Asus Probe (I know it's inaccurate, but it gives a rough idea) and my 3.3V voltages were once more being reported as hovering around the 2.6V mark! So it's probably not my new gfx card causing the crashes - it's my PSU. Now the rail's dropping so low the computer won't even start up, or if it does it just locks up, even in safe mode.
I'm going to RMA the PSU again - however, I'd be very grateful if anyone can suggest any ideas as to why only the 3.3V rail has dropped. The other rails are all within spec. Could anything cause the PSU to degrade like that? Or is this a common issue with Corsair PSUs/the HX620s?
For your information, I'm running a P4 2.6Ghz, Asus P4P-800 Deluxe mobo, 2 Gb RAM, 2 IDE hard drives, DVD drive and CD writer (both IDE). It's not like I'm heavily stressing the PSU!
Thanks.
