You think my PSU can handle the load?

[josh_1413]

I have a thermaltake 420 watt PSU with 18A on the 12Volt. (this one here: http://www.newegg.com/Product/Product.asp?Item=N82E16817153006 ) I am considering getting this: http://www.newegg.com/Product/Product.asp?Item=N82E16814130275
Right now i have an Athlon XP 3000+, 6600GT, 1 80GB HD, 2 optical drives, and a SB Audigy 2 ZS. You think my PSU will be alright with a 7800GS in there?

Thanks for all of your help.

While your psu may be rated at 18A, it can do 20A on the 12v rail. So, yes you should be fine with that psu given your listed config. Mostlikely your total draw under full load will be well below the capacity of your psu.
