System upgrade power output

[boden08]

hi all i am running a 8800gts 640mb oc, amd 64 x2 5000+ and a low end motherboard x8 pci-e.

the problem is i want to upgrade some components in my pc to

ASUS m4a79xtd-evo running 16x pci-e
Phenom 955 3.2ghz quad
ddr3 1600mhz

i am running my original system with a gigabyte 460w power supply and runs it fine, but i wanted to know if this power supply would run the new components, the psu is just over a year old but had no problems with it as yet or would you get a new psu to run the new components.

going on to a psu calculator my original system is using 296w and the new system will be using 344w, dont know how accurate the psu calculators are.

any opinions will be great.

thanks

It may run fine if you don't try overclocking. For insurance, I recommend a corsair 550-650 with single large 12v rail, usually 40-60 amps.

i have been looking at the corsiar tx650 and i am getting the corsair dominator 1600mhz ddr3 and like my components to be matched as close as possible. but i wont be overclocking straight away but will be in the future.
