PSU questions

[fozzy]

I recently upgraded my rig to a q6600, an asus P5Q Pro, 4 gig of ocz platinum ram and a 260GTX 216 sc. I'm not in to overclocking, I just run everything at stock. I also went down the Vista 64 route and kept the old power supply. The psu is a Thermaltake Purepower 680w.

I load up for a bit of FO3 everything wacked up at 1680x1050 (native res) The performance whilst it looked nice, didn't seem that much better than my old 8800gts 320mb. To say I was disappointed would be an understatement. Anyhow, I fired up COD5 and again, it looked great but the game play is very choppy and I get lot's of slow downs and pauses. It also locked up a couple of times for 10 seconds or so.

I'm using the 180.4's I think? (latest from Nvidia) I remember when unpacking the GFX card that the minimum spec for the +12v Rail is 36amp, now I've just had the side off the case and the voltages are as follows...+12v1 14A +12v2 23A +12v3 15A. Does this mean I have a total of 52A on the +12v Rail?

Or is this just a case of me getting a bit giddy thinking I can run everything on high at the stated res? Thanks in advance for any replys.

...and the voltages are as follows...+12v1 14A +12v2 23A +12v3 15A. Does this mean I have a total of 52A on the +12v Rail?

They're never summed together because there's nothing independent in them. (except own "circuit breakers" for tripping whole PSU)
But those values also mean you have modern revision 2 instead of sh*tty original version:

Even if die shrinked GTX260 draws same as original that means ~135W which isn't more than 11A.
(then 80W for CPU and 50W for rest and you'll have rough total peak draw of PC)

Those symptoms would fit also to OS/software problem.

So in short, It definitely won't be my psu? At least I can start trying to find other solutions then, thanks for that.
