PC Electricity Consumption?

[tesco]

With my PC running at idle it shows a draw of 1/3 of an amp.
Under load (Folding@home) it shows a draw of 1/2 of an amp.

Why is your's so efficient? Lynx said they're 80% efficient but by your results they're way more efficient (over 100%, im too lazy to caclulate it).
You sure those are right?
how could the full load be less than the idle?

Why do you keep refering to the power supply output or a percentage of that?

We're talking about consumption here (input).

The PSU is probably about 80% efficient, so the total consumption should be about 600W not 485W.

that or i'm really not understanding something and you should explain.

A 450W PSU is theoretically capable of supplying 450W. If it did, it would consume about 550W (assuming 80% efficiency). But as I said, you don't run the PSU at anything like full power unless you are asking for trouble.

I made a guess at the actual consumption being about 25% of capacity. I knew I was probably on the high side, but I wanted to show the worst possible scenario.

High graphics activity(playing games), high levels of disk activity etc, can probably add a lot to VB's "folding" consumption, maybe as much as double with some graphics cards (but that's a guess) which would bring it in to line with my figures.

In any case, both our figures are an approximation, and in engineering terms a ratio of about 3:1 is generally regarded as being in the same "ball park".

What is your setup VB?

Also connected to the power supply:

1x 12" Cold Cathode light
4x LEDs connected in series to the 12v line (3volt each).

Here is a list of PC parts with how many watts each part uses.

Edit: It's a bit of an old list though... but it'll still give you a general idea.

When it comes to top off the line cards I think you can double the wattage for agp cards given in that list, and PCI-e draws just as much.

I think on-board peripherals (lan, sound etc) will draw slightly less than their pci counterparts.

Big HDs today pull more than what is mentioned there I think, while some AMD processors (mobiles) will consume less.
