PSU for new system

I am building a new system and am wondering if this psu will be enough: http://www.newegg.com/Product/Prod [...] 6817371026
Specs:
i7 920
HD 4890
6 gigs ddr3
antec 902
asus p6t
WD 320 gb hd

I feel sure that the psu is enough for that, but if I throw in another HD 4890, will it cut it?
Also, feel free to suggest a better deal on a psu.

Will be good, Antec PSUs are actually pretty good quality depending on what units you buy.

I have close to the exact same build. Cooler Master HAF 932 instead of Antec 902 and 4870 1gb instead of 4890. I have my 920 oc'd to 3.2 ghz and I only have an Antec NeoPower 650W PSU. You should be fine. I will also slap down a vote for Antec PSU's. I have had mine for nearly 2 years and not 1 problem. Plenty of power.

The only antec PSU I would buy is the Signature series, the True Power New series and the EA series in that order. I would pay the extra $10.00 and get the True Power New.
