Current Testing - FV24
Since everyone is curious (for the most part) as to how much power a motherboard draws. I made a current test jig for +5 +12 and +3.3 and tested the FV24 and the intel 810iEMO
These are my initial findings:
The FV 24 uses the 5 volt line to generate the CPU voltage. My MPBS1 power supply is better suited than I thought. The motherboard doesn't really use much of anything on -5 -12 or +12. It monitors +3.3 +5 and +12 in the BIOS. The fan was the only thing drawing 200 mA on this board. When I took off the fan, the current dropped to 0 on +12 volts.
The high and low currents are pretty basic. I just measured these as the motherboard was booting. I didn't run any operating system or anything. The no ram test probably doesn't have full CPU activity. This will make more sence after I test a few more CPUs and run a benchmark utility. But for the most part these are pretty accurate figures. The Vin and Iin are using my MPBS1 power supply and a gel-cell 12 volt battery. I need to also test the +5VSB voltage too.
Hopes this answers some questions for people, it answered some of mine..

What size do you want the PS?? high power, big size, or low power, small size?? do you want to make the box as small as possible???

SkinnyBoy is going to make the best PSU for you... Hehe
Good Luck!

Project - GAME OVER :(
Well I tested a Celeron 566 and It uses a little more on the 3.3 side. Hmm kinda weird.
Motherboad: FV24 with Celeron 566 1.5v -- 32M RAM (16 chips)
Volts -- I low -- I high --
12 -- 0.2 -- 0.2
5 -- 2.2 -- 2.5
3.3 -- 1.5 -- 2.2
Voltage in 11.06
Current in 2.65

I don't see why you wouldn't... If just 1 person was to trust me, then others would find out from that person that I can be trusted...Originally posted by Charles Enwesi:

And, I would not rip someone off, because that would give me a bad reputation, and then no-one would bue things form me, see, not that I have anything to sell at the moment though.....
