Greetings,

My PC spec:

i7-2600 @ 4GHZ
Gigabyte GA-Z68X-UD4-B3, Sandy bridge
DDR3 Corsair 2x4GB (1600Mhz)
MSI GTX 560-ti Twin Frozr II 1GB DDR5
PSU: Fortron Black Power 650W
(+3,3V/36A, +5V/30A, +12V1/18A, +12V2/18A, +12V3/18A, +12V4/18A, +5Vsb/3A, -12V/0.8A) - SLI ready, efficiency > 85%


is my PSU going to handle MSI GTX 580 Lightning Extreme 3GB DDR5 ?

http://www.amazon.com/MSI-N580GTX-L...MGXI/ref=sr_1_1?ie=UTF8&qid=1314570127&sr=8-1

as this card has cca 30-50W more consumption then my current GTX560. I run it overclocked and I see no problems here. (almost on 1000Mhz Core)

I'm not seeing the problem in W capacity, but that it has 4x 12V separate. So my GPU can use only two of them, so it's about 36A and there is recommended cca 42A. I know some ampers could be used from the mainboard, but still..

Can you guys help me figure it out?

Thank you.

That would be enough, but you should really get a Antec/corsair/silverstone/seasonic, pc power and cooling, or XFX power supplies.
 
Like said. If you going to spend 600 bucks for a 580. You better upgrade your power supply. Its pretty much a cheap lowend unit and will end up taking hardware out wiith it.
 
Thank you guys for answer... I'm taking Corsair 1050W and I'll be ready for future... (SLI, overcloacking, cpu upgrade or so...)

Just for sure... It's not possible to put into SLI these two graphics card, is it? (MSI GTX460Ti, MSI GTX580 Light.Extreme), is it?
 
As I expected, thank you:)..

And I hope that it will be possible to do SLI with the Extreme Lightning version of GTX580 and normal one. As there are different memory 3GB and 1.5GB.... and the extreme version might not be available in future (limited edition), thx for reply
 
You can do it but you will be limited to 1.5gb of VRAM for the entire SLI setup. the other 1.5gb of the lightning will not be used
 
and if you get 2 580's you'll want like a 850w psu, there is absolutely no need for a 1050, at most a 900 watt will be fine for the next 5+ years.
 
I can see a 1050w if he plans on ocing CPU and both GPUs. Still over what he really needs but not all that much over.
