The stuff Dale wants tro buy wouldn't even reach 250ł AT FULL LOAD. Even my rig - hotter, doesn't reach 300W when I artificially torture the system. Normal 'max' load is in 200W range. An normal desktop? Under 100. You don't want to get to far below 20% PSU load or efficiency is shot. So an 800W PSU is stupid in every regard. 650 is way to big. 450 is good enough. 400W might even be good enough. > I've had very good experience with OCZ models.

When the box is on but not used for a while, it might lock up completely. So completely I had to remove the battery and set the bios jumper to get it back working. Asus has become worse than their daughter Asrock. Nothing bad to say about Gigabyte. I am still waiting for a reply from their support. Send the mail 12 years ago ;)
