These are some rough numbers on my tower, my UPS has my 3 monitors on it as well so it looks like roughly 100-120W of this is my monitors.

System under full load ie 3Dmark 2013 extreme or prime95+furmark peaks between 720-750. Highest peak reading never stayed there I would say the avg under full bore would be 700.

Idle it never really idles on my cpu as I always have something going on, but it sits idle at 280W.

I'm the same a BlueByte basically. I have 2 monitors plus external drive, alarm clock and who knows what else is plugged in. I idle around 272 as per my UPS but if I'm running Handbrake or Passware it jumps to 360w. This is with an I5 3570k and MSI 465 w/ 470 bios plus a bunch of hard drives.

3570k @ 4.5GHz, GTX680 SLI @ 1241/3200, 1 PCIe SSD, 1 2.5" SSD and 1 5900RPM HDD pulls 434w while folding on both cards and the CPU.

My HTPC which is a G555 Celeron, 1 SSD, 4 7200RPM HDD uses 2-3W while sleeping, 40W idle, 50-60W watching XBMC or heavy HDD load.

Sli 680 and OC 3570k < 500w!! That's crazy.

My most recent GPU folder with 2 X 8800GTS 512 and a GTS250 draws 447 watts using the BluePlanet meter (folding on gpu's only).

The system in my specs goes from about 180ish when at idle. At load it can get to just about 630-650W. That is everything including fans maxed out.

Thats power efficent for you. Crazy as it is but We are really starting to need less and less of the Big PSU's.
You grab an AX860i for example and thats probably the last PSU in 5 years you need to buy.

My entire PC + 3 monitors + 200W amp + logitech G25 + a printer sitting here pulls about 320W idle, I've seen peaks of 485W when gaming. That is everything in that number, not just the tower.

Power supply needs are always exaggerated as is the advice most people give.

It's a common misconception that a system needs more power than it does, and most builds reflect this, partly in an abundance of caution. It's not harmful to over specify the PSU.

It was a great suggestion to ask for power meter readings, because it really is illuminating. And with a power meter reading, you can use it's PSU efficiency graph to see where you are with it, at idle and load.

Corsair has a power supply finder that I think is really useful: Power Supply Finder

I've used it a bit, and now have a simple rule of thumb for sizing a PSU; "250W for each big gaming graphics card, and 250W for the rest of the system - even with overclocking. Newer gear uses even less power, and lowers the operating efficiency on an over-sized PSU.

I use a 650W PSU and run a single graphics card [GTX 560Ti 448 Cores].
