haha, prepair 1000w psu for GTX285 SLI + GTS250(physx).
the 850w psu is ok for GTX460 1GB SLI + GTS250(physx).

Thermaltake Toughpower Express can power up dual graphics card.comes in 650w version and 450w version.can be inserted onto your 5.25' drive bay.the 450w takes single bay whereas the 650w version takes 2 bays.

Do you think it is possible for me to have a dual monitor setup where on normal windows, it is extended and when it is in gaming, the other screen remains in windows so that I can still browse the internet?

im planning to make sli 2ways with amp gtx580.
does corsair HX850 support this?
Issit worth it to make 2ways sli?

which one is better for SLi? 2 x 1.5gb or 2 x 3gb? wads the difference?

the whole casing is equipped with fan

Added on March 2, 2012, 12:57 pmHi, i've another serious problem, when i play my games in sli mode..the problem is when i launch a game with sli enabled it works but with a lot af graphic problems like green flashes and color bugs...windowed mode everything is fine and when i switch to fullscreen i turns green again. can i know whats the solution

Is a single GTX570 faster than 2 x GTX460 in SLI?

Someone's selling a GTX460 and I'm trying to decide if it's worth picking up the card and replacing my mobo so I can SLI them, or just upgrading to the GTX570.

perhaps u do him a favor by finding a cheap GTX570 seller. 

overall Single card is far better.

firstly, i like to stress that this is my first time build an SLI setup.

ive mounted 2 msi 560gtx ti on my p8z68 v-pro mobo, together with sli bridge, with monitor was hooked at primary (upper gc) dvi socket of the gc, but windows wont boot (monitor shows no signal).

however the win7 will boot;
1) if i take out the 2nd gc
2) or hook the monitor to the dvi of 2nd gc

however nvidia driver did not detect both gc if i go for 2nd step

what is wrong actually?

my psu is enermax 850w 80% efficiency aaa...

yes both of the cards are not faulty. already checked them invidually.
u may refer to my earlier post.

btw ive checked thoroughly in bios, i cant find any device properties regarding gc. btw how should i check in windows7?

Based on reference, it's actually only 170 W. 2x make it 340 W but bear in mind those figures are for MAX power consumption. Actual gaming often don't reach that level.
