I have recently upgraded my PC (Intel 2500K, Gigabyte Z68P DS3 mobo and 2GBX2 Corsair Vengeance RAM, Maxtor 2TB Black HDD with OEM Windows 7 Pro 64bit) and have been experiencing rather frequent abrupt shutdowns/power loss. These shutdowns happen randomly, regardless whether I'm playing a heavy game or simply leaving the PC idle for several minutes. Sometimes power loss occurs just minutes after booting up and sometimes after I left the PC on for a couple of days.
My prime suspect as the cause is the Gigabyte Odin Pro 800W PSU. I bought it in 2007. My old PC (refer to the spec under my name to the left -haven't updated it yet with the current config) had experienced somewhat a similar power loss like my current one. The only difference is that it failed when I pushed the power button. It rarely loss power during gaming or work/idle.
Both PCs do share one thing in common : after the initial power loss, the PSU wouldn't start again. The PSU would whirred to life for a couple of seconds and then stopped. No matter how many times I pushed the power button, it would failed again and again.
My solution to start it again is to pull out both the 24 pin and/or the 4 pin +12V connectors and reconnect them again. Usually this bring back the psu back to life after one try, occasionally more or I need to remove and replace the power connectors for Ati HD 5850 card too. This reminds me : The PSU seems to hate the modular graphic card power cables and the modular molex connectors so I have stopped using them years ago. Using them only make the start failure even more frequent in the older PC.
That's my lengthy explanation of a problem and here are the questions :
1. I know I've been using a potentially defective PSU for years but I am curious to know what had failed. So, what went wrong?
2. Can I keep using this PSU? I'm planning to buy a new one next week but I did planned to rebuild the older component as a second PC. Maybe I could reuse this one for that unless the problems are a precursor to a fatal failure in the future.
3. What's the recommended optimum wattage that I need for the next PSU? I'm not a hardcore overclocker (CPU or GPU). I'm not interested in SLI or Crossfire. I have always felt the 800W I'm currently using is way too much for my style. Then again, I'm planning to upgrade my graphic card (maybe a GTX 560 Ti/570 or anything similar) so do I still need to buy another 800W PSU?
P.S : I'm trying to avoid Gigabyte for my next PSU or graphic card. I don't know why.
