Think my PSU can handle it?

All right, well I managed to get a 7800GT for dirt cheap (thanks PV for the cooler ) Specs are in my sig. Only thing that will be added is the 7800gt and possibly another 160gb SATA HDD. I did a rough check on the PSU calc and got 409W for my system, but you can't know for sure. Think my TruePowerII 430W can continue to do the job or should I try to get another one? Worst comes to worst I use the extra 500W SmartPower I have laying around.

Specs say 17A per rail (2 rails) but obviously can't have that at the same time. I would guess it has a combined amp of 25A or so.

spec sheet if you're interested

WC I`m wondering about how you figure 409w, out of interest.

It`s too bad the JourneySystem`s one is so out of date, but I figure:

CPU 90w+ ???

DVD Drives 25 each, 50w ?

Alledgedly 25w per HD, 3 or 4 (not sure if 160 in sig is the one added), 75 / 100w

It only shows a 6800 ultra @ 7xw, so u may figure 80w+ ??

8 fans @ ~2w each, 16w

memory ~30w+, no idea

Something like 341+ to 366+ pretty rough.

Just curious how you thought it out I guess m8y.
