My 1200w microwave uses 1888 watts

[Miramonti]

I've been taking meter readings using a Kill A Watt 4400 ($28) of actual watt/amp usage for home devices and its surprising how much electricity some use, and how much some don't use.

Sharp Carousel 1200w microwave = 1888 watts :Q
Conair 1600w hair dryer = 1150 watts :frown:
(it uses 50 more watts on med. fan/high heat, than high fan/high heat 😕 )
Hoover Windtunnel 12amp vc = 9.75 amps (1150 watts)
Frididaire refrig = 8 amps (944 watts)
Hampton Bay a/c = 6 amps w/compressor running (708 watts)

Dell 1905fp, 2105fp = 23-29 watts each
canon MP750 all-in-one = 25 watts, while scanning

Total 2 Computers full board:
Athlon 2400xp, Athlon 3500+ (@3800 equiv.), both 100% cpu utilization (using prime95)
2 cdrw's
dvd r/w, while writing
8 pci cards (incl 2 controllers, 2 soundblasters, 1tv)
2 vid cards (for 2d only, 1 dual vid)
5 hard drives
1 usb card reader
2 usb mice/keyboards
8 fans - 80mm-120mm
2 500w fortron psu's
3 Dell lcds (listed above)
__________________
Total: 475 watts for computers/monitors together (4.03 amps)
Total for every electronic device in office, MAX usage (comps, router, stereo): 675 watts, or 1350 watts with a/c.


NOTE: my wall sockets are 118 volts.
Reminder: Amps * Volts = Watts

Your PSUs are overboard for your computers 😛.

can i buy one of those in WA?

I paid $28 @ebay, shipped.

mmm i'm interested now 🙂 cheers mate.

you'd save money by heating up your food with the hairdryer 🙂

haha. 🙂

The microwave's 1200W rating comes from the power it puts into cooking. The hair dryer's rating comes from a marketing dept. 🙂

Something is wrong with that 1888w reading. The Kill-a-Watt meter's 15A fuse should have blown if that reading is correct.

I love the yahoos that insist that LCD monitors use more power than CRT's. :roll:

microwaves aren't generally on 15 amp circuits. Mine is on a 30 amp/220 volt.

Ours have always been on a 120/20A circuit.

The unit's lcd display flashed above 15 amps, and the unit beeped as an alert but still maintained a continuous amp reading. It wouldn't give a watts reading that high tho.

Since you brought it up, I'll plugin my 2 19" crt's after work and compare the two, and post the results.

The microwave's electrical specs are also rated at 1200 watts.

Well good to know there is some leeway before overloading with the max amperage the Kill-A-Watt can take. The highest amperage appliance I used on mine was a George Foreman grill. It runs at like 12A. And I'm surprised at how low my washing machine actually uses - only around 700W.

Advantium pwns jooo!!!!

sucker pulls like 5000 watts or more.

I don't know about washing machines, but don't they run on 220v's, so could it mean that it runs at 1400 watts? (hmm...maybe not, because if you used the killawatt...it only plugs into 120v devices.)

Advantium (pdf)

Advantium: 30amps @ 220v :Q
Advantium 120: 15amps @ 120v

I wonder what will happen if you use the 1200 Watt PSU in a computer... :roll:

My Maytag washer has a standard 3 prong plug. But yeah, my dryer has a 3 phase connector so can't test that.

I measured my computers a couple of weeks ago (including an LCD and two CRTs):

Aren't they great!?!

I just ordered a 2nd one.

My 1000W microwave uses 1025 watts.

My fridge uses 225W.

My computer uses 168W while 100% CPU and 136W while idle, and 6W while off.

My old 15" CRT used 85W

My new 19" LCD uses 23W.

Our VCR uses 10W while on and 6W while off.

Damn, I can't remember how much I calculated it cost to do a load of laundry. 4 cents I think, about 0.5kWh.

Thank you! I really wasn't looking forward to lugging the 70 pounders in here to test. 🙂

It looks like crt's use 3x the amount of electricity as lcd's. I wasn't able to use powersaver mode for my 3 crt's either, so its no wonder my electric bill dropped about $10 a month when I switched.
