E4500 like most Core2 Duo draws up to 65W on +12V rail. 8600GT SLI would only draw 60 watts on +12 rail. A 400W power supply with dual +12V rails could power that set up all day long.

The thing people seem to always forget on PSUs is the amps on its +12V rails. I once replaced a Thermaltake 430watt PSU on a customers computer with an Antec 430watt PSU so he could run a video card. Althou both were 430 watts the one he had only had 18 amps on the +12V rail while the Antec had 24. His video card required 22 amps.
Althou both were 430 watts one could power the system properly while the other couldn't. I would not go with a 400watt PSU for an SLI setup. Here's what I recommend:
http://www.buy.com/prod/corsair-520w-sli-certified-modular-atx-power-supply/q/loc/101/203270716.html
It has 3 18amp +12V rails and is an SLI ready and approved PSU and can handle 2 GTX cards if you ever choose to upgrade. Also has a lot of modular connectors, is over 80% efficient, is ultra quiet and has a 5 year warranty. One of the highest rated PSUs made. Will put most 600 watt PSUs to shame.
They go on sale from time to time and I've seen them as low as 79.99 delivered. I bought one when they were 89.99.

When i buy power supplies i buy them to last a long time 400watts with a decent +12v rail would power that system. But a 600 watt with multiple +12v rails or one large one would definitly be prefered
If you was you i'd stay with the 500watt and up range just for future ugrade security

don't skimp on the pwr supply. 400 is OK now, but if you EVER plan on putting a second disk in, or a larger graphics card, more memory, etc., 400w might still be OK, but, ....
