Antec TPII-480 Enough?

[Puss Chavez]

I'm looking to update from my old AV8 system. I'm looking at:

Asus P7P55D Pro
i5 750
2 x 2Gb Kingston 1333
Sapphire 5770 with 1Gb

The power calculator at http://extreme.outervision.com/PSUEngine shows a draw of 372W at peak load using crossfire, I added in the hard drives and stuff. Should I be ok? I was thinking it was close enough that i'm tempted to try with my current PSU and if I run into dramas nab an Antec 750 or something.

While we're here, is there anything obvious that would be worth bumping up a bit, like will faster ram be a better match for the rest? What timings should I set it at when I put this together?

I'm not looking to overclock or mess around with it too much.

I'm open to suggestions, thanks for your help

Do you plan to have any use for USB 3.0 in the future because i believe the P7P55D Pro dos not have that. Do you plan on using Crossfire with the 5770 one day. also:

is really good memory for the buck 1600 not 1333, 9 dollars more.

A 5770 draws about 8 amps. Your Antec 480 is rated at 33 amps on the 12 volt output.

You can easily power one card. Powering two cards will be really, really close. Whether you can or not may come down to PSU aging factors.

To be honest I don't have much use for USB stuff apart from ipod/keyboard/joystick type stuff, nothing special.

Crossfire I see myself maybe using in a year or so. When prices come down further i'd either hope to get another 5770 an updated card, whichever is better bang for the buck, as well as probably getting a faster CPU - an interim upgrade before the next time I do the whole thing.
