Power Supply Calculator?

Hardware PSU
1

Is there a way to Calculate my power consumption? I want to see how much of my corsair RM750 PSU I'm actually using. I have seen a few webpages that seem to calculate it but are these accurate? can anyone recommend anything?

Also how much power do mouse, keyboard, and other peripherals use?

Current PC spec's (nothing is over-clocked)

  • Intel Core i7 3770 @ 3.40GHz Stock Intel CPU cooler
  • Asus GeForce GTX 970 Strix GPU
  • Asus P8Z77-V lx Motherboard
  • 8GB G.Skills ARES DDR3-1600 RAM
  • Corsair RM 750 80+ Gold Rated PSU,
  • Western Digital Black 1TB HHD
  • Western Digital Green 3TB HHD,
  • Seagate 4TB back-up drive (via usb 3.0)
  • Samsung 840 Evo (250gb) Boot SSD,
  • Cooler master Scout 2 case

Buy a KillaWatt.

That's a good Idea, just need to find one with Australian plugs

I can't help you there, sorry.

With a killawat you can indeed check how much your system is pulling from the wall.

But i think it will be arround 350W ish on full load, something allong those lines.
maybe even less.

G'day mate here's a bloody good watt metre for ya .http://www.jaycar.com.au/p/MS6115.

Yea most of the online calculators say around 350W

Thanks of the help guys/girls

top would be 330-350 but what @MrChumps said you want to know it more accurately get a watt meter like the jaycar one. The situations where a lot of deviance occurs with those meters are more on the low end spectrum and then I mean <10 watt.

PC Part Picker seems pretty accurate. However that just shows the maximum power draw, to accurately work out your power draw at different load levels you need something like the kill a watt as suggested by @thedmbarlow
