Hello I have been running into some strange issues with my PC and I assume its a issue with my power supply, I just recently bought a second 7950 and my computer cannot run with both of them in crossfire. I have a Antec 850w that is around 5 years old now. It is missing most of its modular cables so I had to use 2 Molex to 6 pin adapters to get both of the GPUs plugged in and when I tried to run them in crossfire the computer freezes often and will just shut itself off wile under load. When I try to turn Xfire on or off via the CCC It displays a black screen with a blinking white "-" in the top left corner and Im not sure what that is about. I recently upgraded my motherboard and CPU and those have been working wonderfully I just assume my PSU is getting old and unreliable. So I need a new PSU that will run all my stuff wile they are overclocked my system is as follows
MoBo: Asus Crosshair V Formula-Z
RAM: G.SKILL Ripjaws Series 8GB (2 x 4GB) 1600
CPU: AMD FX-8350 Vishera 5.0GHz Eight-Core (H100i)
GPU: 2x Sapphire Radeon HD 7950 3GB Crossfire
I have 3 Sata HDDS for storage and 2 SSDs running striped for my OS and important programs drive. I have been looking at the Corsair 850w but they have so many different ones Im not sure what one to get.
