The Best PSU Calculator ever!!

I don't think you guys understand how accurate this thing is.
Remember 4.6Ghz is a massive overclock for most people, the guys taking their sandy cpu's to 5Ghz usually have insane watercooling loops and they tend to know what they are doing.

I have been doing a lot of reading on this, and I was going through how they made it and all the data collected, and its amazing to see the results.
Hopefully this will save a lot of people come cash.

I like this online one, caters for everything but not sure how accurate (seems about right)

Extreme.Outervision.Com/psuengine

How do the two compare?

I'll give that one a try sometime.

When you guys have time, read through this.

Real world power usage (User submitted values)

I know its a lot but it'll open you're eyes.

Just one of the guys that went through that test.

Check this out:

System Specs:
System: 2600K @ 4.6GHz @ 1.33V . ASUS Maximus IV Extreme P67 . (2) 1.5V 4GB DDR3 modules @ 2133MHz . (2) ASUS ENGTX 580, 900MHz @ 1.125V . (1) Intel 510 SSD . (1) SATAIII 6GB/S 1.0TB HDD . (1) BD-RE . (1) DVD-RW . (9) ~5W Fans . Enermax MODU87+, min. 90% efficient.

Power Usage:
Max Values:
Prime95 Only: 298W -> 90% = 268.2W
Furmark Only: 591W -> 90% = 531.9W
Prime95 + Furmark: 731W -> 90% = 657.9W
Prime95 + OCCT: 711W -> 90% = 639.9W
Game (Crysis): 649W -> 90% = 584.1W
Game (The Witcher 2 [UBERSAMPLING ENABLED]): 688W -> 90% = 619.2W

this calc seems pretty good,but i do find the lack of options somewhat perturbing...
i typically use this one,it seems legit (havent checked it)
eXtreme Power Supply Calculator
seems to be the same as the one that was posted earlier,but this link works...

Very interesting! I'll need to review my psu needs.
