Just checked the specs on your PSU and it seems that you may have a dud, not saying that is your problem but that particular PSU has 6 12v Rails so that means you are only getting about 166 Watts per Rail which is only 13.83 Amps.

The best PSU's are single Rail with large Amps, for instance if you had a 800 Watt PSU with a single rail that would give you 66 Amps which is what you really want to go for especially with an SLI setup.

do i have to get a new PSU then ?

then my monitor blacked out because my PSU wasn't able to supply enough watts ?

Well considering you would have been using them on maximum load when you were rendering and and that's when your problems started, it seems like a good possibility that your PSU couldn't cope.

You need to start eliminating thing though, first you need to check your video cards on the computer your using now and the RAM as well although I think your new Rig is using DDR3 and your current one is DDR2 so you cant test that, did you try resetting the CMOS yet?

From Palit: This graphics card requires a power supply unit: A minimum 450W power supply unit (with a minimum 26A current rate for 12V) , one 6-pin PCI-E supplementary power connector.

So even though he has a 1000 Watt PSU the individual rails are only providing half of what he needs to run just one, ironic isn't it.

the PSU's box says it's SLI & CrossFire ready...

im going back tomorrow for repairs.. any chance that it may damage my system ? other parts of the motherboard ?

and ask if i could replace the PSU


EDIT:
which PSU is advisable ?

I would recommend a good single rail 800 Watt PSU, something like this.

SilverStone Olympia OP800 (SST-OP800) 800 Watt (800W, 800Watt) Power Supply- 66A Single +12V Rail, Active PFC, High Efficiency
