Hi there, I'm currently using this power supply http://www.coolermaster.com/product.php?product_id=6641 to run a single MSI R7850 power edition. I know this card uses very low power consumption but I'm planning on getting another one to run it in crossfire. Will my current PSU be able to power 2x 7850s power edition without any problems or do I need to upgrade my PSU?

I might as well put this in if it helps, this is my rig; I do alot of gaming but that's all.

PROCESSOR - Intel® Core™ i5-3450 Processor
MOBO - ASUS P8H77-V
RAM - Corsair Vengeance 8GB Dual Channel DDR3
HDD - Seagate Barracuda 1TB/7200RPM
GFX - MSI R7850 2GB DDR5 Power edition, Overclocked edition
PSU - CoolerMaster GX-550W
Case - Coolermaster Elite 311 Plus

Thanks!

Here is Guru3D's power supply recommendation:

Radeon HD 7850 - On your average system the card requires you to have a 500 Watt power supply unit and 650 Watt if you go with two cards in Crossfire mode.


If you are going to overclock the GPU or processor, then we do recommend you purchase something with some more stamina. http://www.guru3d.com/articles_pages/amd_radeon_hd_7850...

I'm not planning to overclock or anything so a 600-700watts PSU is good enough?

Depends on which one not all are trust worthy or reliable but if it's a reliable one then yes 650W will do
