800W isnt enough for a setup like that, there are a few poor picks in there too.


Im rather curious why you think you need a 6990 and a 6970 for a single 1920x1080 screen, thats a lot of GPU power a single 6970 would do pretty well, but more importantly a lot of heat and on a Sandy Bridge system at 8x/8x at best they arent going to do very well, the 6990 will be bottlenecked pretty good. I would cut that back to a single 6970, in which case a good 750W unit would be plenty(my good list is Seasonic, XFX, Corsair, or Antec)

I do a LOT of video editing, and when i do its heavy. In addition, I have 3x 46" Vizio HDTVs to setup in Eyefinity.

Would an 1100 watt Cyberpower PC PSU be enough?

Based on your requirements, I suggest the following:

(1) Get yourself a full tower case for great cooling. I chose the CM Haf-X for my Eyefinity setup.

(2) Consider the option of going with an Intel X58 motherboard and a Core i7 970 hexacore processor. This way you would have x16 support for both of your high-powered graphics cards, and a hexacore processor to boot.

(3) If you do go with a P67 motherboard, consider getting one with better PCIe support. This quarter's system building marathon with two AMD Radeon 6950 cards used an Asus P8P67 WS Revoluion motherboard that can support dual x16 (of the same card) or quad x8 graphics:

(4) Using two 2GB Radeon HD 6950 cards would provide much better bang for you buck and much less power consumption:

Heck, if you go with an X58 platform (or even the P67 with the Asus card above), you could choose a motherboard that supports three of these cards.

(5) Get yourself a decent power supply. There are many reviews here that suggest the CyberpowerPC power supplies are poor quality. Once you determine your power supply requirements, then do a careful review of available choices.

(6) You can determine your PSU requirements here:

You might want to pay for the pro version to make sure you get it right.

Dont use any power supply from them marked as extreme gear or cyberpower or raidmax. If you do you will just be back on here posting about power and boot issued.
Get a corsair or themral take or silverstone.
