I'm just wondering about my old rig, previously i posted few question about my old rig but something that i should ask is left behind, i mean the important question is left behind, Now i need to ask you guys about it, My old rig is using Asus GTX560ti and i'm wondering that should i changed my power supply if i'm gonna add another GTX560ti for SLI mode ? My current power supply is Cooler Master Silent Pro M series 600 watt.

No. Get a good 850 watt by corsair, antec, or ocz, not coolermaster.

Sli'd GTX560Ti's can be run on a good quality 600w - 650w PSU, personally I feel that an 850w PSU is overkill unless you don't have a problem splashing the cash.

It, most likely, wouldn't survive a run of FurMark with two GeForce GTX 560 Ti in 2-way SLI in that system.

That power supply unit is also short by two PCI Express supplementary power connectors that you would need for the second GeForce GTX 560 Ti.

Furmark is a pointless heat virus and my PSU is also short of two PCIe power connectors.

I agree with you. But some still want their systems to be able to handle it.
