Hello,

in 4 weeks I'm planning to put together a custom build and I'm quite sure about everything, except I'm not 100% sure about the power supply.
Here is my setup:

CPU: AMD FX-6300
MOBO: ASUS M5A97 R2.0
GPU: Sapphire R9 270 factory overclocked
CASE: Zalman Z11 HF1 Plus
PSU: Enermax 500W (83% efficiency)
RAM: Kingston HyperX Fury Red 2x4 GB
HDD: Seagate Barracuda 1TB 7200 RPM
OPTICAL DRIVE: Samsung SH-224DB
WIFI ADAPTER: TP-Link TL-WN851ND

I have been told that 500W with 83% efficiency will be enough to power all of this, but just now I realised that I was talking about R9 270s in general, not the factory OCd version from Sapphire. So I ask: will my PSU handle all of this (and could I possibly also do some future overclocking with it)?
Here's the link to the specs of the PSU:

Any help will be grealy appreciated :)
