is 80 W enough?

post #1 of 14
Thread Starter 
i'm building a mini-ITX system with this case http://www.newegg.com/Product/Produc...82E16811165041 and you can't replace the power supply. but what i was wondering is will 80 W even be enough for this mobo/cpu/video, a HDD, a slim dvd-rom drive, and a stick of ddr2 533?

Well lets do the simple math and use a watt estimator along with some logic.

The motherboard/processor/video combo uses (I think 60 watts). I know for a fact that the processor alone uses 25 watts. And everything else may use up to 80 watts alone. I am not really sure on this one..

well i was hoping to be able to sell little mini-ITX windows home servers to people when windows home server comes out. I have a repair business and it would be great if we could sell people a tiny little server that backs up their computers, and then when something goes wrong with their computer they just bring them both in and it would make the repairs go a ton faster and cheaper for both of us.

TDP is only like 10w. Your HD uses more power.

It uses regular desktop memory, but the speed is only DDR2 400MHz. Might be able to save some money by getting that as opposed to the 533.

I have a lot of experience with the mini-ITX world, and none of them use very much power at all, the biggest PSU I have ever used with a build is 90W, and that had 4 3.5" HDD's in a RAID.

PS: I never buy mini-ITX from Newegg, go to www.mini-box.com

Here is the board there: http://www.mini-box.com/Jetway-Versa...=8&category=99
