most likely it would, but i'd surely reccomend you a 850-900W psu.
My old 450W ran 2x 8800GTX Sli, but i got loads of BSODS and random shut offs.

750 would have a hard time doing your needs especially if you even attempt to oc...id go with the corsair hx1000 its 1000 watts. it would be great if you start to oc. or add anything to your system. you really only need around 900 watts tho

Your PSU will be fine. Hell, you can even run 4 of those cards and still get away with it.

You'd need to use 2x Molex to 6pin PCI-E cables since the 750TX only has 4x PCI-E connectors.

The max power of draw for one 9800gtx is 168W. So, three of them are around 500W. Then A OCed quad with base stuff. All those wattage is from 12v rails so I would say 850W.

850w+ just to be safe.

Better safe than sorry!
