Seasonic 620W (SLI GTX 260)

I'm planning to get a AM3+ motherboard to do a SLI as I currently have a spare GTX 260 lying around.

Below is my computer specs,
AMD X6 1055T (1.3V version) with Coolermaster V6 CPU Cooler (2 LED 80mm fans)
ASUS Sabertooth 990FX motherboard
2 pieces DDR3 RAM (i guess)
1 SATA 500GB Hard Disk
1 Blu Ray Drive
1 DVD RW Drive
Coolermaster HAF 912 casing (2 LED 140mm fans, 2 LED 120mm fans)
Seasonic M12II 620W

My question is, would my PSU be able to support two GTX 260 with a motherboard upgrade (does it push my PSU to it's limit?, or do you recommend a PSU upgrade )
Thanks for your help.

my psu has a 48A on the 12 volts rails. Does doing a SLI of 260 push the PSU to its limit @ 100% load?

no it shouldnt.

It should be ok.

The guru3d always has a higher rated psu wattage it should be ok on your rig.

It should need around 20amps at least on the 12v rails for single gt 260 and gt 260 in SLI it should need at least 38 amps.

270 is a system load? Anyway mine is a palit gtx 260 (216 core) sonic edition X 2, it doesn't really matters right?

it should use less power or the same.Few non reference cards go above the reference power consumption.

That psu is more then enough to run 2 gtx 260.

Source running 2 of them on an antec earthwatt 500.

Yes; it will run the 260s in SLi without any problem.

Overclock the 1055T (northbridge too) or it'll bottleneck the 260s.
