Is this psu calculator accurate?

post #1 of 10
Thread Starter 
If so that'd be great, it says a 2500k overclocked to 4.5ghz, 2 sticks of ddr3 ram, and a single 6950 only needs 404w and that includes a sata hdd, fans and dvd rw drive, sounds really low and adding another 6950 only brings it to 521w, sounds really low.

It's pretty accurate, yeah. Sometimes it's a little high, other times it's dead on. It's rarely lower than what you need. Your gaming load with that system would be around 350W, LinX+Furmark maybe 400-415W.

It may not be accurate, but its certainly precise.

Pretty accurate, but don't skimp out on psu. Get a quality 550w antec or similar.

I love that tool. I used it so much I decided to support it and pay for it! (It may seem crazy, but I like to know my output per rail)

It can still be inaccurate with certain cards/options, but it is one of the better ones.

A simple calculator and some research will give you a better perspective on psu load. guru3d and other sites give you power consumptions of their reviewed products.
