Does more TDP means more electicity bill?

yes but depending on how much its pretty minimal maybe a few dollars a year/6 months

It depends on the CPU

The thermal design power (TDP), sometimes called thermal design point, is the maximum amount of heat generated by the CPU that the cooling system in a computer is required to dissipate in typical operation. Rather than specifying CPU's real power dissipation, TDP serves as the nominal value for designing CPU cooling systems.

But generally, the higher the TDP the more power its capable of using.
But all in all, it wont have much of an affect on a powerbill as long as the PCs load isnt maxed out 24/7 and the like.

So does 1070's tdp which is 150w have slightly difference between 1080 tdp which is 180w?

nah thats really not much for a GPU

and it only goes that high when gaming, if that
while nothing GPU bound is going on not much power will be used due to the GPU being idle.

All in all, as far as a GPU goes that isnt a lot at all

It doesn't mean as much as between a bronze rating PSU and gold/platinum/titanium rated PSU. You would be saving a lot more money (and get much safer) in a quality PSU instead of worrying about the component usage.

Yeah as said, a Quality Powersupply can help with that

[Big Boom Boom]

Generally a gold rated PSU is the sweet spot. You don't get super expensive like Titanium ($1000 PSU? You're welcome http://www.digitaltrends.com/computing/coolermaster-masterwatt-mij-1200/) but at the same time they USUALLY made of quality parts and save quite a bit on the electricity bill.

1200 is overkill

a quality 750w is plenty

[Big Boom Boom]

Heh, and $1,000 price to boot.

High TDP CPUs/GPUs will really only impact high power usage when they are under heavier loads. When those hardware are idle, very little wattage from wall is used for the most part.

[rotNdude]

Yes, a higher TDP component will increase your electricity bill.

[Astraea Kisaragi]

If your are bothered, then build a computer with a good performance/wattage ration with a efficient (at least 80+ bronze) power supply
Pretty decent CPUs out now arround 65W or less, also both nVidia Pascal and AMD Polaris are now eating much less juice as their predecessors.

[Bad 💀 Motha]

Yes the next gen CPUs and GPUs tend to pack more performance at lower TDP per performance.

Such as most 1070 being right around max TDP of most 970 GPUs; but the 1070 is much higher performance per $
