Techdude I REALLY don't recommend that motherboard for what specs you have...they're super-good and you're spoiling them by getting such a low-end motherboard. And I recommend you go Western Digital for the hard drive. It's much more reliable. WD1002FAEX is 1TB. Now to calculate power:
CPU: 95W
Motherboard: add 25-50W
HDD: add 12-15W
Opt. Drive : 15-20W
RAM: 10W per stick - 20W per 2 sticks (I REALLY hope you're not just buying 1 stick of RAM, are you? Get 2 x 2GB of RAM and call it a day. Why skimp? Go for quality RAM if you can afford it! They are not too expensive, the 4GB set, ask ROG store for that if you can, or at least replace them by something else.)
Nvidia GTX 560: 150W (also here I recommend you go for the 560Ti. You definitely will not regret it! And considering you pay almost the same for a GTX560Ti with stock cooling, and a DirectCUII 560Ti which is much better cooled @ ROG store, you can't go wrong with a 560Ti. He may even be able to provide you with the 560, with a warranty and personal support. Keep that in mind.)
Fans: 10W (probably using up to 4 fans)
Also, this case. I recommend you get something better for the same price.
Total: 95 + 50 + 15 + 20 + 20 + 150 + 10 = 360W
Divide that by 0.7 to make sure that max load will reach 70% of PSU sustained load capacity, and you get 514W. So a 500W XFX power supply is enough. If there's anything you shouldn't buy cheaply, its the PSU! If you would like to upgrade later, go for a bit higher. It will give you a nice margin. Now from the previous thread I know you would not like to OC, though I would kill for it, but it's your call. Factor in an additional 20-30% into power requirements for (enough for safe OCing with slight or no overvolting), if you would like to OC eventually. When you've got proper cooling, an OC shouldn't hurt. You'd upgrade long before it does, if it did. What's the difference between 10 and 12 years, for example? It may be even longer, I don't know depends on the components. Good luck!
