Hi everyone, new here to ask for some advice.
My current specs...
Striker II Extreme motherboard
Intel C2D e6750 2.66GHz running @ 3.10GHz
2 x 2GB DDR3 Corsair RAM
2 x nVidia 8600GT XXX XFX graphics in SLi
2 x Seagate Barracuda 7200.10 500GB HDD
OCZ GameXstream 600W PSU
For power purposes I also have:
Thermaltake Flower CPU fan
DVDRW optical drive
Floppy drive
Linksys Wireless G PCI card
Total of 5 x 80mm fans with LED and 1 x 200mm fan without LED
Everything is around 2 years old, apart from the motherboard and RAM, which are about 1.
Recently, I got 2 used eVga 8800GTX KO ACS3 nVidia cards from eBay. I know, sounds dodgy but bear with me. So my aim was to swap out the 8600s for the 8800s.
Did it and fine, not a problem - system was grand. But, last night I was playing some Supreme Commander, maxed settings, and after about 2 hours the PC just powered off. Not a restart or a blue screen, just off. Now, I had SpeedFan logging (I often build PCs and temperatures, especially on these big 8800GTXs, is something I watch) and the temperatures seem fine, the processor is around 35 idle 42 under load, and the GPUs are 60/50 idle, 70/60 under load (primary card / secondary card).
I can replicate the power down with FurMark, where the power down occurs in about 2 seconds. Using a measuring power plug, I read about 320W idle. Unfortunately the refresh rate on the power plug isn't great and all I can see when I run FurMark is a spike to about 480W before the PC shuts down.
I'm going to try with only one card in later but for now I wanted your opinions - power issue right? A shut down (rather than a blue screen or reboot) would only be caused by either heat or power, am I correct? So, if confidence is high that heat is not an issue, then that only leaves power.
The OCZ 600W PSU has been solid but it is 2+ years old... capacitor aging maybe putting me just under at peak usage?
Just curious because if the GPUs are damaged then I need to return them, but otherwise I'll just buy a bigger PSU.
Really appreciate the help, thanks.
