I'm looking for a relatively good power supply for my build:
Cpu: I5-3570k
Cpu cooler: CM Hyper EVO 212
Gpu: PNY Gtx 760
Mobo: Gigabyte-B75M-D3H
RAM: (Stock) 8gb
HDD: 1TB
Chassis: Thermaltake Commander MS-I Edition
Fans: I have 5 fans...if that matters

I was also thinking maybe this one:

I kinda want to stay away from corsair. Basically just trying out different PSUs and i hear seasonic was pretty good thats why.

yea Seasonic is the best for PSU's and XFX would probably be next and then generally youd have your Antecs and Corsairs. But as far as the G series Seasonic goes and the TX Corsair, they sit in the same tier of quality ranking. They are both Tier 2 (class A) Units.

yeah 550W is plenty, but when you want to upgrade the GPU to a 770 or 780 the 650W would suit you better. for the 760 as it is, 550 seasonic watts will do you plenty of justice, and a bit of headroom. Do you plan on overclocking the CPU or GPU?

its not all about watts, its about how many pcie connectors there are and how many amps are on the 12volt rail. in this case, all of the above psu meet your needs.

yes they all "meet your needs" but he should understand what factors are most important in a power supply unit. While more watts might not be "needed" they are recommended so that you can run the unit under a lighter load. That is, a 200W unit has to work twice as hard as a 400W unit to power the same 100W PC. this generally equates to LONGEVITY=LIFESPAN. When comparing two units made by the same OEM and sit in the same tier ranking, the 650W in the same system as the 550W will be under less stress.

idea usage is 50%, not higher or lower, cuz the efficiency peaks at 50%. so cuz those are all tier 2A, i would go with the 650 watt cuz it will be used about 50% while under load.
