Just for interest...
I'm the original poster and yesterday bought a cheap tester from a high street branch of a large electrical component wholesaler/retailer.
I tested my main PC which is on about 15 hours per day on average. The setup consists of HP LJ 1300 on standby most of the time, a canon i865 inkjet printer on standby most of the time, a VideoLogic Sirocco Crossfire 4 .1 amp and speaker setup which I just leave on all the time, Multisync 20WGX2 Pro 20" flat panel screen which has quite an aggressive automated switch into standby if not in use (and I do switch it "off" at the front panel when I am not going to use it for a few hours), and finally the base unit (quite old) consisting of NF7-S (or is it NFS-7, can never remember
) Mobo, couple of 160GB PATA drives, Athlon 2400XP+ processor, couple of gig of RAM, 7600GT AGP video card, Creative sound card, 3 x 70mm case fans and a few other odds and sods like floppy drive, tape drive, and a couple of optical drives. I turn the base unit off overnight.
Even running flat out in a 3D game (WoW) it is only pulling around 180w. Interestingly when printing on the laser printer the power spiked at over 1000w but I'm not really surprised by that - laser printers are high power devices when actually printing.
Assuming 12.5p per Kilowatt Hour which may be a little low now, it looks like my little setup costs about 2p per hour to run. Thats about 30p per day. About £2 per week. About £9.00 permonth. About £110 per year.
I've never really though about this much before now. £110 per annum is actually quite a lot, but in terms of value for money it is stunning value. It is clearly NOT the major item of my annual household elecrical consumption though.
With the base unit and screen off the remaining gear draws only anout 20w.
