Thread: Has anyone gotten a sproggy to work with EPIA boards?

I take the lack of replies as a big fat NO.

i got my sproggy up to 600mhz with just a regular hard drive attached... I think anything more is pushing it beyond its limits

You can always try to use a laptop hd, that might work... I cant guarantee it though

I am powering a Via Epia 800, Lappy hard drive, and USB LCD from a sproggy.

You've got about 65-70W of power to work with. Don't go overboard, but don't think it's the end of the world. People were using the sproggy for quite a while with plenty of sucess.

HOWEVER - you'll find that it's much easier and cheaper to probably just daisy-chain two of the mini-ITX power supplies together (one for the mobo components, and one for your additional hardware).

And if you're still exceeding that kind of power, then screw it, go get a OPUS power supply.

All I am trying to run is the 800mhz ITX board, laptop CD-rom, laptop harddrive.

But the thing wont boot up at all. It boots fine with a regular PS.

When I manually ground pin 14 on the sproggy header it powers up and supplies the correct voltages. It just does not power up when connected to the ITX board.

ANy help here?

Are you using any PCI cards? Also are you certain that the RAM is seated properly. Check your connections and make sure the mobo and/or sproggy isn't grounding out. Try bootting a different motherboard with only video and ram (no other drives, etc) to see if it's a current problem.

I have the M9000 and Sproggy 2.7.

To test a scenario with completely minimized power usage, I've tried powering up the motherboard with absolutely nothing attached. nothing. no memory, no keyboard, no harddrive, nothing. (even tried unplugging the processor fan). All on-board peripherals are disabled (i.e. lan, audio, etc)

With a desktop ac powersupply it starts up, POSTs and as expected complains loudly about missing memory, etc.

With the sproggy it just spins up the motherboard fan, but never POSTs. With a keyboard attached, you can see the keyboard flash as it gets initial power.

EPIA M-series motherboards are already known to need more than 65w of power at startup. This has been posted repeatedly under threads entitled "EPIA M" and various other "OPUS AND EPIA" threads.

If it won't work with an OPUS, it won't work with a sproggy.

Yes I have seen that statement before. The comments I saw were only speculation though and the person didn't really know for sure. Just saying it need > 65Watts is a little vague.

Now, if someone could prove that the 3.3v rail for instance requires X number of amps, but the opus and sproggy only supply < X, then we can attempt to fix the problem.

Supposedly OPUS made a simple? mod to the original version of their power supply to make it work. That seems to imply that it was something besides a redesign to increase in power output on a particular rail. ? No one seems to know what the mod is though.

In any case, it is likely a lack of power, but I would like to establish exactly on which rail(s).

For reference, I was able to make the M9000 work with a small (150w) AC atx power supply with the following specs:

3.3 7A
5 12A
12 5A
-12 300mA

I have a sproggy 2.7, which has the following specs: (approx 85watts)

3.3 5A (peak 6.5)
5 10A (peak 13)
12 1.3A
-12 100mA

does your m9000 work properly with the sproggy ?
