good enough PSU

It will run a 4890, probably two of them even. Have you already purchased it though? A corsair could prolly be had for a similar price...
 
haha ok thanks for the advice i'll have to scounge around for another 25 bucks haha thanks for your help i'll go with the 850 corsair thanks again
 
Both would be fine. 750W The Antec is a multi rail with 62 amps total (12V rail). The Corsair is a single rail with 60 amps (12V rail) Both good Supplies. The Corsair is 5 bucks cheaper. Toss up. Close your eyes, spin in a circle. If you fall to the left, get the Corsair. If you fall to the right, get the Antec.;).

Both are fine and will power the cards easy.

They would both power the cards fine yes, but in his current rig. Id say go for the 850W mainly for the fact that in the future, its gonna be smp vs highly clocked single/dual cores, which will eat up more power. PSU is one of the few pc components you can futureproof, so for the money you should imo. Plus i would go corsair over antec mainly for the fact a single 12v rail is easier to work with imo.
 
Thats true, but with even a i7/Phenom II X4 system, couple of harddrives, blah blah blah, average setup running 2 4890s the top pull would probably be little under 500W

True, but im sure youve noticed the trend in TDP in the last, ~2 years the quads pretty much doubled what the duals needed as far as power. Plus soon amd comming out with those 6/8 core chips? Same way with future gpu's, look at how much more power say, a 4890 uses than a 2900XT from years past?
 
Well thats somewhat true, but really the power consumption of CPUs has dramatically dropped. Look at a old 754 Athlon 64 single core with a TDP of 89/90W and ran on a 1.50/55 voltage, then look at a Phenom 955 with 4 cores at 3.2ghz with a TDP of 125W with voltage at 1.15/1.45. If you tried to put 4 core of the old athlon together it would melt the motherboard:D. I understand what your saying but even with a 750W he will have around 300/350W overhead and probably about 20 amps to spare.

Most minimum requirements are really overstated because they know there is alot of cheap power supplies out there.
