Is This Build Fine?

[Squonix]

Hello,
I have decided to make a new gaming PC and after months of researching, I have come to this conclusion:

GPU: R9 280X (Dual-X with 3GB V-Ram)
CPU: FX 6300 (Stock clocks)
PSU: Cooler Master - 500w (I know this brand is not good and 500w is not good either, but I had no choice due to some problems)
RAM: Kingston Hyper-X - 8GB (2x4 configuration)
Motherboard: Gigabyte's GA78LMT-USB3 (in combination with my FX 6300)
Cabinet: I don't know yet, but I will buy the one which will be obviously compatible with all of my components.
OS: Windows 8.1 64-Bit
GPU Drivers: Probably the one which is the latest version and has Mantle in it.

I have already bought the components, except the GPU, I will be able to use this PC in April, so by that time, new GPUs may hit the market.
So, please tell me if this build will work fine for 2-3 years with a monitor (1920x1080 resolution).
And if you think the 500w PSU is not enough, please recommend me one, I am planning to slightly overclock the system.

500w is a minimum mark for such GPU. Better to have a little headroom with the wattage somewhere around 600W since you are planning on overclocking. Also That coolermaster Power supplies are not reliable. Try something else.

It should be OK. But if you buy stuff you know isn't good don't expect it to last 2 or 3 years.

Thanks, I am thinking about the CX 600 entry-level PSU, will it be enough?
The Seasonic is a good brand, but kind of expensive (http://www.snapdeal.com/product/seasonic-520w-power-supply/1379226).

Yes. That PSU will serve you well.

You should say if you aren't in the US in your Opening Post.

Thanks again, I have found the same PSU for a cheaper price:

Since you are an expert, I will go with whatever you say.
