These are my specs:

Motherboard: ASUS M5A99X PRO 2.0
CPU: AMD FX+8350 Black Edition
RAM G.SKILL 4gb 2 x (8gb) 1866 hz DDR3
HDD: don't remember the name.
Cooler: Cooler Master 212+
 
It's more than enough power has a nice single +12V@62 amp rail.

Review below , it's decent.

The Thermaltake SMART 750W SP-750P power supply unit operates very quietly or even silently depending on the load applied to it. When testing the unit out of the box the fan didn't even bother spinning until I had enough components installed – with the stock 4770K test system sans optical and storage drives idling in BIOS the fan was barely spinning; I could count the RPMs by eye!

The overall design seems pretty solid; the only part that was off-putting was finding the CapXon capacitors inside opposing the Nippon, although they have come a long way from the days when they would burst regularly. Plus Thermaltake offers a five-year warranty to help negate this attribute. Some sacrifices were made to make this unit available at a lower price point. The cables are long, which is both good and bad (good for big cases where you would have to stretch to reach connections, bad for small where it's hard to hide excess). The ribbon cables help to keep the wires managed whereas individual wires would easily become a mess. The all-black insulation also helps with the looks. The Bronze 80 PLUS rating seems like a fair compromise between efficiency and price point.

In the end this power supply unit may lack some of the bells and whistles that high end units may offer, but it provides a fairly substantial power output while remaining efficient in consumption, noise production, and price point. This design is something that the majority of consumers could benefit from.
