I found this a little earlier today, Extreme Outer Vision has got a calculator to recommend a PSU wattage. It's quite detailed. You input all your system information, even over clocking and peripherals, and it figures out how much your computer will draw.

They'll also calculate 12V, 5V, and 3.3V rail amperage, but not before they shake you down for two bucks. Fail.

Anyways, I hope this will help some folks figure out how much juice their new rig needs.

I've been using that one for the last few years.

It's a great calculator. I highly recommend it if you're building a compact HTPC.

If you can't derive the amps then it's fail, lol. Wattage means nothing without the amps.

it says i need 333 watts lol. quad core at 3.6, ddr3, hd4850...333watts...hmmm

System's seldom need a 1000W PSU.

It's well known to those who visit SPCR.

I actually paid for the Pro version of that calculator and I think it's worth it. I've been using that PSU Calculator for a very long time. I'm glad you posted this man. I seriously think it should be posted or bumped at least once a month on here.

Anyway, that's probably the most accurate PSU calculator on the internet. Granted, it's not accurate, but it's probably the most accurate. I actually find it to be frighteningly accurate with my rig.

Yeah, it's pretty bogus. I guess $2.00 isn't that much, but I can't see why they need to charge extra. As if there aren't already enough ads on that page :S.

Did you remember to input all your peripherals? I used it to reference my new build (Phenom 9850 + HD4870 and etc) and it came up with 395 or something like that. Crossfire made it 575, though, so I opted for a 620 Watt corsair to give myself room to grow.

It doesn't give you how much you need, it gives you how much you'll draw. The default setting is 90% system load, at any rate. Leave some fudge space.

For some reason, I assumed it was $1.99 a pop, do they tie the purchase to your account so you retain the license? I'd skip a candy bar to have a better idea of an appropriate PSU for a build.

Check this page out for more details on pricing. http://extreme.outervision.com/pro.jsp

I bought the "Lifetime Limited Access" (I think they meant "Lifetime Unlimited Access" since the others are limited).

The Calc suggested a Ruger Redhawk .41 Magnum for me...
