Kill-a-Watt to view things such as power factor provide the OP with no useful facts. All computers must startup and work normally even when incandescent bulbs dim to 40% intensity. Is your voltage dropping that much? Then fix a potential human safety problem inside the walls. Meanwhile, those DC voltages on the orange, red, purple, and yellow wires do not vary even when bulbs are that dim. That is what electronic power supplies do. Make AC voltage variations irrelevant to electronics.skier wrote: some states let you take out PIII KillAWatt meters from public libraries for energy efficiency programs (Maine does at least). plug the computer power cable into the meter and let us know what it pulls for wattage at the wall (homedepot/lowes also carry them for $29.99.. They are very handy devices, I keep my rig plugged into one 24/7)

But when selling to people without basic electrical knowledge, then 800 watt supplies that are also missing other critical functions can be dumped into the market. Most every PC draws about 200 watts. Its power draw may even peak at 350. A 20 amp power circuit means even 2400 watts are easily supplied.
Not exactly. But read spec numbers for computer designed by engineers. They don't waste money on 800 watt power supplies because a PC does not need that much power.XstollieX wrote: So are you saying that no computer will peak more than 350 at the wall?
