Working out what size PSU I need for a server

Speccing up a Dl360 G7 server for a client and trying to work out if we can get away with the lower 460W PSU's.

I found the HP Power Advisor tool but it seems that only tells you what total draw the system will take on the main electrical phase, not what PSU you can get away with.

It'll be a DL360 G7 (470065-374) with 48GB RAM, 3 SAS 15K SFF Disks and a FC HBA.

    Every one I've ever built will run on 460W PSUs, certainly all single CPU ones will. 470065-374 comes with 750W one though and redundant PSU must match so you either need to buy one 750W for redundancy or two 460W ones and take the current 750W one out.

    I've already had the problem with that particular model, no idea why they put 750W PSU in it, it's well over specified. If someone orders two of them I advise buying 2*460W PSUs and shuffling so there's a 750W server plus a 460W one.
