Default running a TT 480W with DFI NF4 Ultra-D

Hiya,

Does anyone forsee any power shortage problems with me running a Thermaltake purepower 480W PSU with a DFI NF4 Ultra-d mobo, AMD x2 3800+ and an Ati x1800xt. I am upgrading my mainboard, CPU and graphics card but keeping my PSU for now.

I wanna be sure my PC aint gonna fall over on me because i dont have enough juice......

Ok heres a photo of the side of the psu, not great quality but it is readable.

12V says 18A, and back to the left it goes 30A then 40A. I have feeling that may not be enough??

I fear that 18A will probably not be enough for that powerful video card. I would say 25A is the bare minimum, however it is likely that PSU has 2 12v rails which would mean it's enough.

26A is the minimum for 12V for DFI N4 mobos with 7800gtx or atix1800xt I just found that out last night, looks like an upgrade for me, coz i dont think my TT PSU only has one 12v rail.

I was thinking this would be an adequate replacement

Can i get some feedback on that
