500W or 600W - 2U / Quad Core / 8-drives

[fibroptikl]

I am specing out a server for a customer. I'm debating as to use a 500W Zippy Redundant Power Supply or 600W.

It will run a Phenom 2.2GHz Quad Core, 8GB DDR2, and 5 Seagate ES.2 TB drives in a 2U Form factor.

I'm thinking 500W should be enough. I'd do 600W just to be safe, but the difference in price is $100.

What are you guys thinking?

I would do 600 watts just to be safe.

Your constant draw is about 200w with a full load on the CPU.

I say 600watt as well.

500w will be plenty. Don't waste your money.

The 500W Zippy is plenty. These are server PSUs, not overrated consumer stuff.
