650W + Nvidia 560 Question

Last response: in Graphics & Displays

Im trying to buy a Nvidia560 (Maybe a 570?) but I'm unsure if my PSU can handle the AMPS.

Here is a link to my PSU.

http://thermaltakeusa.com/Product.aspx?S=1207&ID=1506#T...

and I am using the EVGA website for reference on watts and amps

560

570

http://www.evga.com/products/moreInfo.asp?pn=012-P3-157...

I noticed on the PSU webpage it says 12v with 18amps max for each 6 plug ( It says I have 4). The Nvidia 560 for example needs 500w with a 30amps with two 6 plugs. Does it mean 30amps TOTAL or for each 6 plug? If its total my PSU should be ok since two plugs would mean I have a max of 36AMPS (18v each). Sorry if it sounds confusing (can you tell I am?)

Is it possible to get the 570? it says it needs 550w 38amps. I doubt it though.

Im having a hard time figuring this out as I am not up-to-date on video cards. Please help!

I have a i5 2500k w a Gigabyte z68ap-d3 mobo.

I have no idea how that works with multiple 12v rails, thats why i always buy single rails so i know im good :p 

But you should be fine honestly.

Im not sure if its additive or what, you have 4 12v rails with 18 amps each, not sure how to interpret that sorry.

Yeah It maybe time time to upgrade my PSU but im just trying to get the most out of this one I have before I make the plunge. Thanks for reply scotty99.

Still looking for help!

Best solution

It means 30A total, not 30x2 for 2 power connectors.. Correct way of finding Amps in multiple rail is

total Wattage under +12v rail/ 12 = Amps

In this PSU they say it has 52A in 12V rail.. You are good to go..

Thanks lakshitharxx!! Totally makes sense now.

Now since im armed with this info does that mean I can get a 580? What about your thoughts on a 6 to 8 pcie plug adapter? My PSU does not have a 8 pci plug needed for a 580.

Here is the specs on the 580

Minimum of a 600 Watt power supply.
(Minimum recommended power supply with +12 Volt current rating of 42 Amps.)
An available 6-pin PCI-E power connector and an available 8 pin PCI-E power connector
