On the PSU, most PSUs have a "peak performance" zone - you want to buy a PSU that will be in that zone for most of the time you use the computer. So it should be a bit overpowered but not too overpowered, else you will be in a less optimal zone on PSU usage.
I didn't spend a lot of time digging through details and reviews and calculations, though.
I've just recently redone my husband's PC with that very board (Sept) - he's an AMD-predisposed guy but I went intel as well, and with that very motherboard. Great board.
One of the things I pay attention to is the power usage idle and in use. This is because I like my systems as quiet as can be.
If you read up, the power performance (from an energy use and therefore cooling/quietness point of view) of the Intel processors is better at the moment. Seems AMD didn't care about that aspect much. Lower idle consumption, lower full load consumption, it adds up to less energy bills but also less heat and therefore less noisy cooling needed.
On the other hand I went AMD for the graphics because at the time the power usage for the performance you get is better, especially in idle mode or when the screen is asleep but not the machine.
For info - happy to give details on the hardware or check things.
He's on Windows 8 on this machine and only the AMD graphics drivers give any kind of occasional trouble.
case: Antec Solo << all the noise/vibration features of the expensive Antec cases, at a more reasonable point, and looking, well, normal!
Graphics 1GB Gigabyte GV-R777OC-1GD rev2.0 H << AMD radeon, sweet price point
Gigabyte GA-Z77-D3H, Intel Z77 << great chipset, fab board, was already win8 ready when i bought it in September
Intel Core i3 3220, S 1155, Ivy Bridge << was at the time great price, overclockable quite a bit (which i don't do, it goes back to "quiet".
Scythe Shuriken Rev.B Quiet Low Pro << great cooler
8GB (2x4GB) Corsair DDR3 Vengeance << i pay zero attention to memory details and performance, so this is just what looked good, no research.
Only went for 8Gb, although if he starts coding/compiling again I'll up the memory and CPU (not holding my breath). But RAM prices had gone up and it is easy to upgrade later, so I made my compromise. Even in games, not noticing that RAM is a limit at the moment
For comparison, here's my spec - whereas husband's is all new, mine is a mix of stuff I'd bought a year before or earlier this year
Antec Solo Case << had already
Gigabyte G1.Sniper M3, Intel Z77,
750W Be Quiet Dark Power Pro 10
Plextor PX-891SA 24x DVD±R, 12x DVD
Intel Core i5 2500k << had already
8GB Ram (don't even remember)
Intel 320 80GB ssd drive SATA II (filled to about 45-50, boot drive only)
WD Caviar Black 2Tb SATA III (files, games, apps)
Scythe shuriken low profile
HIS HD 6870 IceQ X Turbo << had already
