Power Supply Calculator
I've seen a few to date, but this one is simply impressive in the breadth and level of details covered. Besides overclocking, you can factor in Peak Utilization, Capacitor Aging (Explained at the end of the page), and Surge Compensation which deals with the power surge required when you first power on the system from a cold start. From my experience trying to calculate what my main rig draws, the number given was very accurate.

Great find but this was posted a long time ago here:

Yea, this PSU Calculator has already been posted a long time ago...but I wanna say that I personally think this is the BEST online PSU calculator.
I'm using this one ALL the time...and the good thing is that it's being updated ALL THE TIME with the latest hardware!!!
So...let's put it that way...VERY RECOMMENDED!!!Intel Core 2 Quad Q6600 (G0) @3.4GHz (8 x 425)
Gigabyte GA-EP45-UD3P Motherboard
Scythe Mugen II CPU Cooler
OCZ Vista Performance Gold XTC PC-6400 DDR2 4GB (2x2GB) @800MHz 5-5-5-15@2T
Gigabyte HD6950 2GB @HD6970 (Unlocked Shaders and Clocks )
CoolerMaster HAF-932 Case
Sapphire PurePower 950W PSU
60GB OCZ Agility SSD (FW 1.5) w/ Windows 7 Ultimate x64
1.5TB HDs --> DATA
Logitech X-530 5.1 Speakers Set

I think we should have an area in the site for keeping decent links like this just incase you forget them.
A handy "Links" section for overcloacking tools, small programs, and other tools like the PSU calculator.
Thanks Couger for the repost, I may be buying a new one soon. It never hurts to plug in the #'s.

Can someone explain surge compensation? Do components need more power when the computer first turns on or something? And what PSU Utilization has to do with anything?

thats the reason PSU wattages are important to gamersSystem: Thinkpad W510 "Rex"

So what's the difference between PSU Utilization and Surge Compensation? Shouldn't 100% PSU utilization be the equivalent of the startup surge?
I mean, everything makes sense to some degree. But I just get the feeling that you can easily overshoot a reasonable wattage for your computer by a longshot by playing it safe on this thing.

I think PSU Utilization is the amount of load that is put on a PSU and Surge Compensation is the power surge required from a cold boot to start up but I am not 100% sure.

If you load a game and play on the highest settings your system can handle, both your CPU and GPU are going to drastically increase their power consumption, usually by half-again their current power draw. If you are playing a game on high settings, maybe listening to an audio CD at the same time too, your system will be drawing the most power that it can possibly draw, therefore it would be at 100% utilization. Idling is almost no utilization, a full system load would be 100% utilization. It's a setting to see how much your system would draw as a "worst-case scenario" if you ran everything at once to it's highest potential.
Surge compensation is different an just deals mostly with when the machine is cold booted and the +12v line is heavily stressed by all the system components and drives spinning up at once, while the CPU is loaded down booting the system. I suppose you could say it's like adding a little extra headroom, since hard drives alone need a small surge in power to get the physical disks spinning, before they can operate at their normal power levels.

I understand that. Now I'm asking, what is the difference? Why not just include startup power necessity in the 100% utilization figure. The note on the calculator is confusing.Recommended to add an additional 15-25% if you are not sure about you PSU peak load reliability.

Even though already posted, i wanna say thx from the new members... Just decided to go with a 700W instead of a 600W, great calc.
