Ok another noob question but, I've got a spare PSU and I've finally have decided on a build I want and will a 520W PSU be enough to power the following

Gigabyte-EP45-UD3R

Intel Pentium Wolfdale E5200 2.5GHZ

Radeon 4830

2GB G skill ram

Seagate barracuda 640GB HDD

Some random IDE optical drive I have

Yes, by a HUGE margin.

This is pretty good for working out what PSU you'll need.

Yes. Good part choices, by the way.

thanks everybody. and does anyone if newegg will ever get XFX's 4830 on sale, b/c I really like the double lifetime warranty on it.

@shaq: They probably will... just give it a little time!

ok one more question. I was also thinking about getting a artic cooling freezer pro 7 HSF, but that has a 4 pin power connector and the EP45 UD3R mobo has a 6 pin slot for the HSF. Would I still plug the HSF in the same spot or do I have to use an adapter or w/e?

The UD3R has a 4 pin fan connector. It's on the Upper left edge of the motherboard, if you use the top-down pic on newegg as reference. It is marked "CPU_FAN".
