At ideal, your PC my be consuming ~70-80 W excluding monitor.

From wall

OP

~100 WATT

btw G2020's IGP intel HD 2500 is better then Geforce 210 so no point in using that(Correct me if i am wrong)

So better sell it it will reduce some load/power consumption

I'll soon upgrade man ..

my measurements with clamp meter says that usual desktop PC draw 250 to 350w watts. cheapest budget PC draws 100 to 250 Watta. high end gaming PC with multiple hdd draws 300 to 600w.

How do you calculate the power usage cost from that?

depends on the configuration buddy.

How do you calculate the power usage cost from that?

you have to know what rates are charged per Watt-hour by government in your area (which they don't tell easily ). then you can multiply and compute .

So at 390w usage with 10rs per unit and 12 hours a day comes to 46.8 rs a day. That sounds reasonable enough. I'd probably add 20 rs more for 2 monitors per day.

Correct. 10 rupees per unit is very high. You should verify the tariff.

it was 0.2A

means

240V x 0.2A=48W

it was 0.2A

means

240V x 0.2A=48W

what method have you used?

also you forgot to multiply the value by 1.4. that's the rms value.

some experts will be able to explain you more.

also don't forget to add in 30% extra cost as government meters are bogus and are set to overcharge you. (verified news )

this clamp meter method is used to install MCB's in houses or any other place in distribution boards because it gives accurate value

for example i have installed a new 10A C-Curve MCB ( will trip if load exceeds 10A, continously, not for milli seconds )

and my lightning load with fans and pc was 11.5A, and it tripped, so i canged it to 16A C curve MCB

this method gives really a very close approximate of the current running through the wire....

clamp meter costs 350 rupees here in local shop, no name brand

thanks for the enlightenment. my clamp is sanwa pro series which costed 4k and measures both ac and dc amp. it's a 'hall effect' meter, you can google about this. however I've always had to multiply the value by 1.4 for AC power. suppose I'm measuring a fan that says 400w in user manual. , I've had to multiply my reading by 1.4 to get spec values.

more knowledge shall Help bro.

so what should i do with my meter? a 300 rs one with only ac amp measuring and voltage....

should i just multiply Amps x 230 = Watts ? am i correct
