Default GTX 460 SLI

I was wondering if there would be any major issues if I ran a EVGA GTX 460 1GB and a MSI Cyclone GTX 460 in SLI on a Corsair VX550W? also does SLI support three monitors but not in surround mode? I want to use One monitor as my main+gaming, second monitor for webbrowsing/chatting and the third display would be a HDTV that will be used when watching movies.

Here are my fulll specs

E8400 @ 4Ghz
P5Q PRo + SLI Hack
2x2GB DDR2-1000
EVGA GTX 460 1GB - Stock
MSI Cyclone GTX 460 OC 1GB - Stock
1x Vertex 2 SSD - Boot drive
1x Samsung 250GB HDD - Games/large files
1x DVD Drive
Corsair VX550W

I've tried three displays but it just causes massive issues that require multiple reboots. I'm just hoping its the SLI hack and not the eVGA card. I purchased the EVGA one used for $70 bucks with the warranty.

lets see

going by teh specs you should be fine, since both cards take around 250 watts

from your 12v in normal gaming mode and your system perhaps 150 watts

and going by the specs on the psu it should take it.

and a review of it

My System Specs


gtx 450 is a 150w card... It would work but you'd need to use the 2 four pin molex to 6 pin pci power and you're PSU would run hot, not to mention unsupported SLI could be buggy.

It's do-able but I wouldn't recommended it.

he can still do it. ive run two on a weaker psu :)

as long as you dont deal with crappy parts,especially psus, dont be afraid.

sure headroom is good, but why not give it a try? :)
