Your Colorsit 480W only has 17A on 12v rail, thats almost suicidal for a 6800
+5V 45A
+3.3V 30A
+12V 17A
Not quite true, my X-Pro 400w was rated at about 16-17A for the 12V rail and it has powered my 6800GT (and the rest of my system) for the past 3 odd years without a single issue. Admittedly they did subsequently revise the label to read 20A without changing the internals but people do have a habit of overestimating the requirements.
BAMBI said:Remember PSUs are not about wattage, the Amps are important especially on the 12v rail.
True, the amps are more important than the simple rating of 500w or whatever.
BAMBI said:The 4x AGP slot would be a large bottle neck too, unfortunately that doesn’t matter anymore.
Disagree here though, the difference between 4x AGP and 8x AGP is usually around a max of 5-10% as most of the graphics cards available on AGP barely saturate the bandwidth available and even the ones that do will only touch on the full capacity fairly rarely.
BAMBI said:Edit: i think the 4x AGP slot used 1.5v while the 8X 3v.
AGP 1x used 3.3v, AGP 2x used either 3.3v or (more commonly) 1.5v, AGP 4x uses 1.5v and AGP 8x uses .8v (i.e. the AGP 3.0 standard which might be where the confusion stems from) but is compatible with motherboards supplying 1.5v.
spawner there is no way that the graphics card cannot be backwards compatible, it is an inherant part of the AGP specification. If it somehow caused your AGP slot to blow you were (very) unlucky but that is all it is.
