How can I tell how many watts my PSU should be?

[Legend8887]

I don't have an exact build yet, but it should be pretty extreme. 4930K and SLI. Where can I go to tell how many watts my PSU should be? I actually put a build together on PCPartPicker.com but it said it estimated 583 watts. It seemed like it would need a lot more, though.

Use this PSU calculator & add another 100 or 150 watts to whatever it says. You'll probably need a 750w.

What do people need 1,200 watt PSU for then?

Extreme cooling as in a lot of fans or liquid cooling? I want to have a two GPU setup and an HDD and SSD.

1200 watts for two or more graphics cards. Generally, anyone with two or more cards, probably have a high end cpu and are probably overclocking, hence the wattage.

I agree with everyone that headroom is important. 100-150 watts more is good headroom. (your pc won't work so hard)

Yeah, that's what I would have/do.

Good rule of the thumb with partpicker is to add 150W to the estimated power use. So in your case 750W PSU will work fine.

a good quality 750/850w psu like the be quiet dark power pro 10 series...

Adding 150-200w is what I usually do. Get a Corsair 750w/850w if you want your rig to work fine.

If you runing a simpale game rige with one decent graphics card 750 watts will do it nicely. What cards are you SLI with ? and that is 130 watt prossore

You pay for amps not the watt :) higher the amp the better for running more than 2 vid cards ,,,all you guys forgot the amp value ,,,,lol lol

overclocking cpu, ram and gpu, running two or more graphics cards, etc.

[_I_]

overclocking cpu/gpu will only take +50-100w at most
adding 3-4gpus 200-300w ea is what needs most of the power
more hdds will use about 10w each
fans maybe 3-4w ea

amps are directly related to watts...

P = U x I

Watts = Voltage x Amperes

Just get a good one, fibbing on power supply spec is rampant on the low end.
