On another note I just ordered a cheap dabsvalue case which comes with a

Do you think I might still have been able to power the GFX with the ATX
1.3 PSU seeing as its not an SLI setup (the GFX has a single 6pin > 2
molex connector) or do you think it was wise to get the newer PSU with
24 pin connector.
An 8800GTS should max out at about 9-10A on the 12V line, so you could
get away with an 18A PSU if you had a C2D and a couple of HDs. Any more
than that is pushing it, and it's generally not a good idea to run a PSU
too close to its specs.
Either way both PSU's probably aren't much cop seeing as Q-TEC have a bad name and the one in the dabsvalue case is bound to be cheap...
Yeah, that's pretty accurate :-)
