What size power supply would you say is appropriate for a high end desktop system running an Intel Core i7 2700K processor overclocked to 4.1GHz, six sticks of DDR3 memory, Nvidia GeForce GTX 580 videocard, solid state drive for the OS, a mechanical hard drive spinning at 7200 RPM for storage, and four 120 case fans, two of which have LEDs? Here's a better question: Why guess?

Outer Vision's online "eXtreme Power Supply Calculator" has just been updated to include Intel Core i7 2700K processors, along with several Corsair Hydro water cooling kits (H40, H50, H60, H70, H80, and H100). Outer Vision also stomped on a few bugs, including:

• Fixed issue with CPU overclock not reflecting the correct wattage
• Fixed duplicate LGA 775 socket
• Added option to browse all CPUs per brand

All in all, it's mostly a minor update, but part of that is because it's so robust to begin with and even includes options for much older systems than the one we spec'd out above. Speaking of which, the recommended PSU wattage for such a system is 509W, and no less than 459W, according Outer Vision. Surprised?

The Power Supply Calculator is free to use, or you can pony up for Pro version, which goes into a bit more detail and includes 3-way SLI and Quad CrossFire X, an amp breakdown on the +12V, +5V, and +3.3V rails, recommended UPS rating, and a couple of print results pages. Pricing is $2 for one week, $3 for a month of access, $7 for a year, or $10 for lifetime access (set at 200 years).
