is there a good psu for 7800gt sli for around $100?

people have recommended this to me, but would 550 watts be enough?

550 watts is plenty, what you really want to look at is whether or not the psu has dual 12 volt rails and the amps on each of the different rails, that power supply is actually very good, alot of the people on this forum have one, and generally the consensus is that it's very stable, i would recommend it for sli

I also think it's a good PSU. I just helped my friend build a new system and they are VERY nice. Good quality and very nice to work with!!! I'd get one if I was you!!!

No one has said, which is surprising. But if you DONT already have 2 7800gts, pls dont get it. Dont bother with sli.

Just pick up a 7900gt/x or a x1900xt , the only reasoning behind your getting another 7800gt should be that you have a 25" lcd and need to run the res at 2048xblah blah . The game play will be better due to optimizations with the newer cards, plus it will draw less power. Better filtering options, etc.

Get a newer card if you can, you will thank yourself and your $$ will thank you.

i agree with the other guys and just upgrade to the 7900gt/gtx. But if you really must go sli, i think that PSU would hold... might want to check out the one in my sig its a little pricey but, it is modular, and has 3 12V rails (one for mobo/cpu, and 2 for whatever.) when set up correctly each card has its own rail.

well, i havent bought the 2nd card yet cause i was expecting the price on the 7800's to go down pretty quickly due to the 7900 release.

selling my 7800 on ebay could be an idea...but i like it a lot and it can run everything i throw at it. i just guessed that the 7800s should be down to $200 in a little while and i might snag me another one then.

is there really that much improvement in the 7900s? ive heard that they are only about 5% to 10% better..tops. anybody had any hands on experience w/ em?

7800GT's prices have not been going down since the 7900 release. If anything else, they've been going up. A 7900GT or GTX would be a much better idea.
