How many Watts for PSU

[ribpeal]

Any help would be appreciated! These are the specs:


SAPPHIRE Vapor-X R9 270X (GPU)

ASUS A88X-PLUS (Mobo)

AMD A8-7600 - 3.1GHz, Quad Core (CPU)

Corsair Vengeance 2x8GB DDR3 (RAM)

WD Mainstream 1TB 7200RPM (HDD)

ASUS DRW-24F1SR (DVD-RW Optical Drive)

500w would suffice, however better to invest in a bigger PSU so you'll be able to reuse it when you upgrade your video card (or going Crossfire/SLI), so I'd say at least a 650-750w PSU, make sure you get one that is 80+ Bronze Certified with 40A+@12V rail from a known brand like Seasonic, Antec, Superflower, EVGA, OCZ or Corsair (avoid it's CX series).

Why would I avoid the CX series?

 

[RaDiKaL_]

While the CX series rank fairly well in reviews, it's been reported that it's components deteriorate way faster than expected, reducing the PSU lifetime by a considerable time (years).

By how many?

Depends on the usage but many people end up having issues with it around the 3rd year, others even the first year though those are really few cases.

Agreed on staying away from the CX series.

Jonnyguru is the authority on PSU testing. He grades the CX lineup as a tier 6 of 9 tiers. There are many better PSUs for just a few dollars more. Really worth it.

Something like this would be great in your system:
XFX TS 550W - $52.99

It's made by Seasonic, one of the best OEM makers in the industry. Very high quality PSU.
