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

If you can manage to load all 4 cores and 3 gpus fully I don't think it would draw more than 700-750W. It recommends a PSU wattage, not how much your computer will draw. A 1kW PSU is about as low I would go for that rig. This calculator is a somewhat useful resource, but any person with some knowledge about PSUs can do the same thing in a few seconds and be able to recommend a few PSUs to power it. Quality is just as important (or more) as capacity and that is not something this calculator can do.
Hmm. That doesn't sound right. Shouldn't it be a little higher than that?
Not really. With a small OC on that CPU, it will probably use 80-90W. An OCed 9800gt will use between 100-120W. Then add ~50W for the motherboard, HDD and soundcard and I come up with 250-280W.
Generally, around here a 350W usually isn't enough with highly OCed dual cores and especially quads with power hungry video cards. But since he's got a low power dual core with a light OC and a 9800gt that doesn't need a lot, a ~400W PSU will do just fine. But if you OC a lot or upgrade to like a gtx260 it would be better to go up to a 500W or so. The fact is is that there are very few quality ~400W PSUs since quality parts are expensive. You could build a good 400W PSU and sell it for $60 or you can make a good 600W PSU and be able to sell it for $70. Higher wattage PSUs are able to absorb the cost of quality parts easier.
Also a lot of people here buy with room for future upgrades or they run multi card setups which can really jack up the power needs. So yeah, a dual core at stock or close to stock speeds and a mainstream video card will run easily on a decent quality 350-400W PSU. Dell, HP and just about every other PC company does it all the time.

Nice. I learned a lot from you right here. Thank you.
I figured I'd just bump this thread since there is no need to start another one.
I've got a few different questions on power supplies. I've used different calculators, I've read diferent threads, but I'm still not sure if my current psu is enough for what I'm thinking of doing.
If I added one more WD 500GB to my sig rig to RAID 0 with the other one. Then added another 7200 HDD, a PCI sound card, a PCI 1x TV tuner, a USB webcam, and my system had 4 92mm fans and a 120mm fan, with lets say a 4.0ghz OC, and a moderate gpu oc, how would my OCZ 600 watt fare?
I've heard quality is better than capacity. I know OCZ isn't the best, but will it do for this setup?
