I'm thinking about getting this power supply http://www.tigerdirect.com/applications/SearchTools/ite.... It looks pretty good to me, but I'm not good when it comes to selecting computer components. Would it be enough to power a 6950 or 6970? Also, do all power supplies come with the right amount of connections or am I going to have to open up my computer and try to see what kind of connections I need? Thanks for the help!
Cool Master PSUs are usually not so good, but the Silent Pro series is the only CM PSU that is worth buying (it performs overall very well, so no need to be worried). With 850W, you can run 2 6950/6970s. Usually, all PSUs come with the necessary wires. If not, the PSU manufacturer usually selfs kits of extra cables (not sure about CM, but NZXT and Silverstone do).
Thanks for the reply. Would you recommend the PSU I posted above? I'm sort of on a budget so I'm trying to find a Modular PSU under $100. Of course I'll be willing to pay more if it means better quality and longer life span.
As far as PSUs are concerned, be informed. Before you buy any PSU read accurate, objective PSU reviews at reputable sites such as www.jonnyguru.com or www.hardwaresecrets.com on the EXACT model PSU that you are interested in as some brands have good and poor quality PSUs.
You can also get an accurate rating of how much PSU power is required for your current or future system at the PSU calculator link below. Once you know the total PSU watts required then you need to confirm that the 12v rail has enough amps. to support your Vid card(s) and the rest of the PC system.
There are several websites that show the Vid card power consumption in watts. Divide the watts by 12 to determine the amps. required on the 12v rail(s). Add 15 amps for the rest of the PC on the 12v rail and you now know the Minimum total 12v rail amps required under full load. It's best to have at least 5-10 amps. reserve on the 12v rail available under full load so the PSU is not loaded to 100%.
It's also worth noting that people often misunderstand the 80% power rating. This is a rating of the PSU's energy efficiency not it's output. 80% plus PSUs use less grid power to produce the same PC power. If it's 80% Bronze, Silver or Gold the cost savings on electricity is pretty small between Bronze, Silver and Gold unless you are paying very high rates for electricity so any 80% rated quality PSU is fine even if not Gold. For those who leave their PC on 24/7 a quality 80% PSU is a good investment.
could you list what your pc consists of and possible upgrades
I'm not really going to upgrade all that much. I currently have a Phenom II x6 1055t, a 5770, and 4 gigs of ram. I want to upgrade my GPU to a 6970 or 6950 and maybe add another 4 gigs of ram to make it 8.
