What type of PSU is it? Do you know the specific model number?

I dont really think is enough! 24A at 12v is pretty decent! Try it , dont worrie even if is not enough power the PC parts wont be damaged.If the PC will shut down or wont power up or low performance on full load is beacause the PSU is too weak.

model number is cit-450 p4

AMD Radeon recommended a 500 Watt or greater power supply for its HD 6850 Graphics, tough a 450W PSU should work. But the PSU MUST have 2 PCI Express power adapter.

If your PSU won´t work properly, then get a CORSAIR Builder Series CX500 V2 500W http://www.newegg.com/Product/Product.aspx?Item=N82E16817139027

If your PSU doesn't have a PCIE power connector, chances are it doesn't really have enough amperage available on +12V to run a powerful video card, regardless of what the label says. I would NOT use adapters, as contrary to GoldenGPU's post, a cheap PSU can die violently, sometimes taking attached parts with it into the fiery abyss.

A quality modern PSU has full range active PFC (no little voltage switch), and some level of 80+ certification. Seasonic, Antec, Corsair, XFX, and Enermax/LEPA are among the better brands.

That's a decent PSU. And yes, a swap is easy, though it can be a pain to connect the PSU to the 4/8 pin CPU connector depending on how much room your case has and where the connector is.

Basically, you'll have one connector from the PSU to each of your drives, two to the motherboard and that's pretty much it. Can be swapped out in just a few minutes.

That's not correct. You only need one 6-pin PCI-Express power plug for the HD 6850.
