Haswell Build - High Electricty Bill?

[curioususer123]

I'm wondering what my electricity bill would be with the following system:

I5 4670k
4x DDR3 Memory
R9 280x
Z87 Mobo
5 Case Fans
1 SSD, 1 HDD, 1 Disk Drive
750W Gold Rated PSU

(all stock)

How much wattage would I expect to pull while gaming or using in a stress test? If I estimate 480w, and just say the computer is doing this for 14hrs a day for a year (example), this would mean 480w*(14*365 hrs) = 2453 kwh per year.
If the price of electricity is $0.24 per kwh, that would be $560 per year just for the PC?

Am I missing something here as that does seem a bit high. How much would a PC cost idle? My old PC was a HP with a Intel Core 2 Duo stock processor with integrated graphics, how many watts did that pull in comparion? Is the cost going to be much higher?

Your idle power consumption should be really low. For regular 2D desktop use the GPU doesn't really do much and should be really low power usage, same with the CPU, so I'm guessing you will be pulling maybe around 50-75W when idle, then maybe that 480W when gaming. The fact that you have a gold rated PSU should lower the consumption by about 5% which obviously in those amounts adds up to a little bit vs a regular 80+ or even 80+ bronze PSU.

I have a 4670, and a similar GPU.
I draw about 75 watts on idle, and about 300-350 under full load (battlefield 4) according to the UPS I have it plugged into. (Including the monitor)
