Sli 9800gt wattage

[xweetok59]

Hey, so I've gotten my hands on a pair of 9800gt but I was wondering, would 330 watts on the 12-volt rail be enough to sli these things with? I've used calculators and they said that my total system draw would be around 300 watts. Besides the two cards I would have a pentium g3460, an ssd and two ram sticks. Going by TDP that should be about 105 + 105 + 50 + 10 + 10, which is about 280 watts, yet I'm not entirely sure about the accuracy of that. Anybody who could enlighten me?

the 9800gt psu recommanded is 400 watt you need at lease 500 watt psu minimum

that knowledge doesnt help at all though without knowing efficiencies

Like denis280 said with psu keep in mind that even it you could get by with lower wattage power supply you won't have rooms for upgrades or wear and tear over time. However I doubt sli 9800gt would handle anything modern anyways and you probably be better serve with something like a 750ti(A example of a more modern graphic card) over sli 9800gt due to it been newer, more power efficient, and even if the sli 9800gt were faster then something like the 750ti you could still have problems with sli support in games and\or lack of direct 11 support for newer games.

well aware I won't be running any modern games with it, I got my own gpu for that, just want to do some experimenting and wondered if anything bad could come out of sli'ing it.

If you have a decent power supply and a sli compatibly motherboard you shouldn't have any issues.
