I have on order a Via Epia MII-10000, for which I'm trying to size a DC-DC power supply. Does anyone have or know where to find current draw information for either of these units (which I believe are almost identical except for a few port locations and the MII's CF + PCMCIA daughterboard).
I'm still deciding what speed HD to use and whether to include an external CD drive (I have one of the old-school Nakamichi 5-cd changer drives and all the necessary SCSI->USB2 cabling).
I'll be using the 90w Opus for my M10000 Erza.
is there a significant pricedrop between the 90 and the 150W?
with a case on the thing, it's like a $40(us) difference
Thanks for the power calculator link... I couldn't find the draw for the Epia M for the life of me anywhere else... Anyway, I found a (supposedly) 120W power supply on ebay which I bought:
Any opinions on this (although its kinda too late?) The only thing that makes me scratch my head was the 7A rating on the +12 lead looks kinda photoshoped if you supersize that picture, but I'll find out when I get it.
And yes, I realize I won't be able to mount it directly on the mainboard due to the MII's daughtercard, so I will just use an ATX extension cable
You'll probably find that:
It will not regulate the voltage, therefore you will be putting 14ish Volts into your HDDs etc
It will restart your computer when you start the engine
It will not automatically start up/shut down the computer with the ignition
Now you've got that, you'll probably have to spend another $200 for an Opus when you find it's not good enough. Instead of only having to save another $130 for the Opus
Also, that PW120A is just a PW70A with one changed component...and I personally wouldn't trust it as the rest of the circuit is only designed for about 70W
The OPUS 90 watt is designed for the ITX motherboards, and it will work fine for your purposes, unless you're running a lot of high current devices(3+ HDs). I'm selling them for $149.99 from the www.mp3car.com/store Same price as direct from OPUS without the hassle or wait!
I think I'll bite the bullet and go with the 90 Watt Opus (Zip-Lock, thanks for the suggestion). I had a mildly sketchy feeling about the PW120A, but since I had the hot finger and bought it already, I'll probably just re-sell it on ebay. Lets hear it for a lesson learned the (slightly) hard way
