I was thinking about buying one of those new Ultra X-Connect PS and they are pretty expensive, but the 400W one coast the least.
What I wanted to know is 400W going to be enough for my new system:

-------------------------------------------------------------------

Gigabyte K8NSNXP-939 nForce3 Ultra
AMD 64 3500+/Winchester
Corsair XMS, Xtra-Low Latency 1GB(512x2) PC-3200/2-2-2-5
Deciding between Seagate 200GB 7,200RPM SATA HD and Western Digital Raptor 74GB 10,000 RPM SATA
Lite-On 52x32x52 EIDE CD-RW
NEC 16X Double Layer DVD-RW
BFG 6800 GT OC

Is 400W enough for this and possibly more upgrades or should I pay extra $20 and get at 500W.

Pay the extra and get the best .

You are spending a lot of money on fantastic new kit and it would be a total waste if you ruined it with t a psu on the edge . Thats what that psu would be ,on the very edge of enough .

Definetly worth an extra $20

I agree, get the 500. Don't forget you have USB ports, fans, etc. and if you want to add a hard disk or memory later or want to try out overclocking, you will be happy to have the extra juice.

You don't need that much at all. You'd probably be fine with a 300w but i'd get 350 just to be safe. People overesitmate ps wattage needs by a lot.

A quality 350W PSU will do just fine, so if you get 400W there's more room to grow. I have blown 450W rated PSU in two weeks where I was running a 300W PSU for over a year. Cheapo PSUs are usually very light, quality PSU are usually quite heavy (dirty trick http://forums.ubi.com/groupee_common/emoticons/icon_smile.gif ).

Of course if you plan to add several more disks, USB powered devices, a power hungry video card, you will be safer with 500W.
