All the video card cares about is whether or not there is enough power coming into the two PCI-e power plugs. Apparently, with the first two PSU's, there wasn't.

First, you can read about changes to atx specifications here:

http://www.formfactors.org/developer%5Cspecs%5Catx2_2.p...

Just scroll down to the revision history. There is no compatibility issue between the atx versions and your video card.

That Silverstone power supply is a 5 year old model. The maximum wattage and the current (amps) on the +12 volt rail is low. According to the Silverstone web site the current (amps) is listed as just 42 amps. That's what I would expect for a 500 to 550 watt power supply.

I checked the official system requirements for a system with one 260 GTX Black Edition video card . The recommendation is a 650 watt or greater power supply. The 260 GTX Black edition is a power hungry video card.

It is time to get a new power supply.

Corsair and Seasonic are two of the brands that have a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty. Lately we've been seeing a few other brands offering some high quality units.

Here are links to competent technical reviews of the brand new Seasonics X-650 gold certified power supply:

delluser1 - The darn power consumption charts get kind of crazy sometimes.

bit-tech is showing 186 watts at idle, 317 watts at load, and 326 at peak for the entire system for the standard GTX 260. The load and peak were measured while playing Crysis. 600 to 650 watts is high but it is about right for 2008/early 2009 when power supplies operated at peak efficiency somewhere around 50% to 60% of load.

http://www.bit-tech.net/hardware/graphics/2009/01/08/nv...

techPowerUp.com measured video card power consumption only. The reference GTX 260 maxed out at 186 watts all by itself.

Lately we've been having an awful lot of questions about power supplies and pc's freezing or shutting down right in the middle of a game. Wonder if there is a really high spike in power consumption during an intense scene.

I've got my overclocked 65nm Core 192 GTX260 running with an oc'd I7-860 on a 41 amp 550 watt psu , no problem.
I've run it on an Antec EA430 with an overclocked E6850, no problem.
The XFX "XXX" is nothing more than an overclocked 260, it require's no more power than any other highly overclocked 260, those come with 500 watt / 36 amp reccomendations from EVGA ( and are clocked higher than the "XXX" )
