Which Seasonic X-series for this build?

[Stephen]

I'm collecting parts for a new build, and am looking for advice regarding which Seasonic X-series PSU I should get. NOTE: Please do NOT give me suggestions on other brands of PSUs.

I'm looking at the following parts:

- Mobo - yet to be determined
- Intel Core I7-2600K Sandy Bridge 3.4GHz
- HSF - yet to be determined
- Corsair Performance Pro Series CSSD-P256GBP-BK SSD
- Two - 2 TB Western Digital hard drive
- Plextor PX-LB950SA burner
- HT Omega Claro Halo sound card
- Gigabyte GV-R7970C-3GD Radeon 7970 graphics card
- AFT Pro-57U card reader
- Seasonic X-series PSU - specific one yet to be determined
- Cyberpower UPS - specific one yet to be determined
- 16-32 GB of memory (haven't decided how much yet)
- Corsair 550D case
- 3 Noctua NF-P12 case fans

Given the above, which Seasonic X-series would people recommend?

[m1st]

I would recommend the X-560. You might be able to get away with the fully passive X-460, but the 560 would be a safer bet.

I just built a build for a coworker, Ivy Bridge 3570k @ 4.2GHZ, 16GB memory, Radeon 7950 @ 975/1250, SSD, HDD, etc. It takes 50w idle, ~250w gaming load. Full tilt (Furmark + Prime95) is around 350w I think.

Thanks! How about if I do some overclocking?

With overclocking, I'd still recommend the X-560. You'll have plenty of overhead.
