Buying new Video Card, need help with power supply recommendations

Recently i've decided to buy a new video card and have chosen the Sapphire 280x seen

The problem is that the video card needs 750w and I currently only have 500w forcing me to buy a new power supply. I have no experience at all with power supplies and could use some help ensuring the power supply will do the job I need it to do.

Currently my specs are:

CPU: AMD FX-8120 Eight-Core Processor (8 CPUs), ~3.1ghz

Motherboard: Gigabyte GA-970A-D3

Video Card: AMD Radeon HD 7700 Series

Case: Cooler Master CM 690 II Advanced (USB 3)

Operating System: Windows 8 64-bit

I plan to run my current video card as a second card allowing for dual monitors which is another thing I have to take into account when buying the power supply.

I'm trying to find the cheapest power supply that will do the job without sacrificing a huge ammount of quality, currently i'm looking at this one I just need to know that it will work before purchasing.

Thank you in advance for the help :)

  1. A single R9 280X doesn't need a 750W PSU. A good 550-600W is more than enough.

    Addtionally, it will handle up to 4 displays on it's own, there is no reason to use another card.

    A good cheap PSU would be the Corsair 600M -

    XFX Core 550 -
    Antec HCG620M -
  2. Why dont you just run dual monitors from the 280x?

    In regards to a quality PSU, something like the below would suit a dual card requirement. But mostly important is why not just run two monitors off the 280x.

    Edit: Goddamit Rammy, stop typing so fast, beating me to it every time :p
  3. Good point, i'll use the 280x for both monitors, didn't really think of that. Thanks for the help guys i'll probably get the Corsair cx600m :)
