How much power does your pc consume?

I am planning to get a new pc.
I am torn between buying a desktop or a netbook.
A pc with low power usage will be preferred.
If you know how much power your pc consume, please let me know.
I believe an average desktop use about 150watts
while a laptop use about 70watts.
I am not a techie, so please correct me if I am wrong.

@hermitwin, the other site that @lincoln and I run is a tech community called Icrontic. If you post the question there, you'll get tons of help.
That said, I recently reviewed the new flagship CPU from AMD, the FX-8350, and a very massive desktop system draws 274w at the max, while overclocked. You could consider that "maximum" power draw for a heavy, hot, high performance desktop PC. My workstation laptop draws about 191w, while my normal power-saving laptop draws about 35w at full load, 19w idle.
You're usually going to get a lower power draw with a laptop, but that's not always the case.
An average desktop PC (you haven't said what you'll be using it for, which will help answer this question) will probably draw about 90w max. Modern CPUs are much more power efficient than they used to be. If power draw is a big concern to you, make sure to look for an SSD instead of a hard drive, and you'll probably want to look at AMD A8 or A10 APU-based systems.
anyone else care to share.
People are trying to help you. A tablet is suitable for limited usage. It is useless to get a low power PC that does not fulfil your requirements.
You also might find that your old hardware can be made more efficient by using fast software such as Puppy Linux.

I will only be buying tablets in the future or Project Glass when available.

Laptops run 170-350 watts but are less capable than PCs in many ways.
There is your answer, but folks have been trying to say: buy for what you need rather than merely by the power it uses. I agree with this last part and have designed and built custom systems for folks (retired now).
i am willing to sacrifice performance for
energy efficiency.
A 30-50% energy saving is significant.
even tho some may argue that power is cheap.
i believe in doing what i can for future generations.
who knows i may be reborn in 2050.
plus the power used by your monitor 50-100 wattts
The average PC will use 200 watts aprox,with everthing runing
at the same time ie Motherboad video card ,CD, Cooling Fans etc.
The rating of the PSU unit will always be above the expected power used
(Watts) otherwise the PSU would overheat ie a 400w PSU can handle 400w burst but
will run cool all day at 200w
So on average you will run about 200-300 w including monitor and
at a constant use thats 3.5 hours per electric unit (here inIreland thats 18.5c
per unit}
A good laptop i5/7 cpu onboard 18inch monitor will run 50 watt max
you can add an extension monitor for anothe 50-100w
Most laptops run on 12 to 20 Volts dc (Mains transformer 220vac to 12-20 DC)
so much easier to connect a laptop to a battery charged by solar//wind.
