Show me the POWER

[STOPOT]

Hey,
I've been looking to up the power of my current setup. I want to be able to use SLI but I've never used it before. I'm looking to SLI GTX 580s. I don't know how to read the type of connectors a power supply has. My current setup is a i5 2500k, 3 120mm fans, 1 ssd, 1hdd. Can some one clarify the connector names and what they do? Like atx 4 8? and suggest a power supply I can use for the new setup? I've done the calculations for using watts and it suggested anything 800 or more should be good.

I think it requires 2 x 8 pin pci express power connectors. yes a decent 700 - 800w psu will be good for that setup. I recommend a decent corsair psu

Is 800 enough for SLI?

I would get the 850w mate so you have a bit of room. 850w will be fine for that system

Ok. What are the connector names I need to know for SLI 580? I know it takes 1 6 pin and 1 8 pin, is it "PCI-E 6+2 Pin", "PCI-e 6 pins", or "8/6-Pin PCIE connector"? And what kind of amps on the 12 volt should there be for SLI? Thanks

Also, what does it mean to get 12 volt on single rail or multi rail?

 

[dhicks19]

the pci x 6+2pin can be basically both, you use the 6 pin if its a the gfx needs 6 pin and use the extra 2 pins if its an 8 pin power connector. Basically a corsair 850w will have the right power requirements and power connectors for 580 sli
