Power Usage Question

[Edsterr]

Going to be making a new build soon, just wanted to know how much power it would use. The specs are as follows:

I5-2500k (probably 4.6GHz OC)
Noctua NH-D14 (CPU fan)
MSI GTX 560ti OC Twin Frozr II
ASUS P8Z68-V (mobo)
3 x Fractal design 120mm case fans
3 x Fractal design 140mm case fans

a 650 watt psu will be plenty unless you decide to SLI then i would recommend a 750 watt

Yes I'm getting a 650w psu, but I wanted to know how much power it used so that I can figure out how much it's going to cost to run in terms of energy bills.

Thanks for that. Apparently I use ~570W when under full load, and ~500-510W when in normal use (gaming)

know worrys the 650w power supply will be fine then. always want a bit bigger supply just to be on the safe side and still got abit of room incase you want to upgrade

 

[Edsterr]

Yes plus the "570W" was only a recommended guide, the absolute minimum was quite a bit lower.

You're not going to even notice the power consumption from your computer on your power bill. If you're worried about that try unplugging your:
Clock Radios
Instant On TV
Refrigerator
Coffee Pot With Start Timer/Clock
Cordless Phone
Those constant drain devices will put a hurting on your power bill. Your computer running intermittently won't.

POWER REQUIREMENTS for computers

This guide will give you an idea as to what capacity Power Supply you will require when building your own or upgrading your PC.

Add up the power needs of all your components of your computer to find out what size PSU you need.
Aim for around 50-70% of total capacity which should still leave room for upgrade expansion.
