I had a similar problem with my ASUS 570 where all games froze after some seconds.

What I did to fix it was to download a program called ASUS GPU Tweak, and there I put up the Core Voltage from 988 to 1050 mV and lowered the Core clock (MHz) a little bit. After that sc2 and all other games have worked perfectly. I think it would be enough to just adjust the Core Voltage

So you can test to do something similar with your Nividia card. Hope it helps.

It wasn't so much about the power required by the GTX 570, though that doesn't help. The OCZ StealhXStream line (older FSP Epsilon) just had a relatively high failure rate. Sometimes you just get unlucky even if most units (even the same model) would work fine. And another unit with the same listed specs but a different build and design, may be much less likely to fail running the same load.

To the individual who said it's best to use the manufacturers software. It doesn't matter, they are all compatible. I'd always recommend using MSI afterburner beta for any nvidia reference card. It's just a better program.

I have not had these problems with my GTX 570's (Nor with a single one). I do not feel this is a driver problem. I've kept mine updated as I check every week (even got the oct 24th update on the 24th upgrading from the bf3 beta drivers) and i've played many SC2 games recently. Personally, when my GTX 570's heat up to around 80+ degrees I start to see artifacts with my tested OC. The card is hybrid water cooled and normally should NOT be reaching these temperatures under load. If your card is going near these temperatures playing SC2 you should manually set the fan speed to an appropriate level. And perhaps run some compressed air through the heatsink and give it a good clean (with the PC off of course, compressed air is flammable). This might even FIX all of your problems.

OP, you could always try downclocking the card slightly in MSI afterburner and/or manually setting the fan speed to 50/60% (if you think for a moment it's a temperature problem) . See if this fixes your problems. But if it's not cooling related then your powersupply is most likely the problem, and downclocking the card will probably help until you can find a suitable replacement.

38A minimum? But it only uses 2x 6pin and PCIe slot, which totals 225w, which would be less than half of 38A so what am I missing?

GTX 570 can draw over 225W without being overclocked, though not by too much. Listed TDP is 219W. The 75W for the slot and per 6-pin (150W per 8-pin) is just a recommendation for adhering to a certain spec. Some graphics cards, particularly some specialty dual-GPU designs but maybe most notably the GTX 570, violate this a bit.

As mentioned earlier, something with specs of StealthXStream 500W is enough, and most actual StealthXStream 500W units would be fine for a few years at least. It's just somebody's particular power supply that developed issues.

It's a figure that assumes a probable worst case for the rest of your system, for use by people who don't know better. If you know what the rest of your system draws, just use the card wattage specs instead.
