Thanks for your response. I am not wedded to ASUS and will be happy to
look at Intel boards.
I would be interested to hear opinions of various power supplies with
regard to the reliability or various manufacturers and the total output
I should consider.
At least you are smart enough to ask about power supplies. Your system should be fine with 500W or better, assuming a couple of things:
1) Just ONE video card (no SLI or crossfire)
2) A good brand of power supply
Trend is to buy huge power supplies lately, but you really don't need anything larger than 600W unless you are running two VERY powerful video cards. For most systems, even high-end, 500W will do fine.
There are good brands, good brands that put out real duds sometimes, and then there is trash. In general, it's hard to go wrong if you pick something by Silverstone, Enermax or Seasonic. OCZ and Fortron are some other good ones. But there are others. Figure on spending about a hundred bucks or more on the power supply, although there are some bargains to be had for less than that. Post here with the exact model number and price if you aren't sure. -Dave
