Hi everyone! New member here. :hello: 

Right now, I have an Antec Earthwatts 650w Green PSU.

My current specs:
AMD Phenom x4 955 (Planning on upgrading to AMD FX-8150 upon release).
1x GTX 560 Ti
2x4gb DDR3 G Skill
Gigabyte AM3+ 990fxa-ud3

I have been considering getting another 560 Ti for an SLI build in the near future, once I have the cash, however I am unsure if my PSU can handle it.

Here are some pics of the PSU, including specs.

Help is much appreciated.

I see, I have been reading mixed opinions.

That's weird, 650W will probably handle 560 SLI.

Here is something I have read,

"You will notice that both PCI-E connectors are joined to take 12V3 all to themselves. Which, I remind you, is rated for 25A. This means that you should be able to run a single GTX 280 on this bad boy, but one only. And really, SLI on those things takes something bigger than 650W anyway."


GTX 560 Ti has a TDP of 170 watts
AMD Phenom x4 955 [125 Watt TDP]

hunter315 you are right sorry, dident see the Green part.

Thats for the original EA 650, the newer EA 650 Green has 2 rails with 38 A OCP limits on it that have a combined 54 A available so you dont need to worry about the OCP limits on it.

Guru3d had a full system power draw of 449W with two GTX 560 Ti under full stress load. That is well within the capabilities of the EA 650 Green.
