High Green Powersupply for MINI-ITX

**burnout.no** · 01-06-2004, 07:29 AM

Hi!

Though i've just registered, I've been lurking around here for quite awhile.. Anyways, i use a High Green PSU ( http://www.highgreen.nl/products/powersup/powerset.htm ) with my M-10000 and an inverter.. This psu is 12V (please correct me if I'm wrong), but i use the inverter because I don't know enough electronics to make me a 12V regulator.. Any simple schematics on how to do so?

Best regards,
Torbjørn

I'm using that Morex DC-DC PSU. I've currently got it wired directly to the car battery. It has been like that for about 6 months now, and I haven't had any problems yet.

YMMV (Your Milage May Vary)

Thanks for the quick reply!

Really? Is it wired DIRECTLY to the battery, with nothing in between, or are there any fuses? What about voltage high and lows? Does it reboot when cranking? My car's voltage is between 13.4 and 14.3 when the engine is running.. Wouldn't it be bad running this into the psu?

Btw, sorry for my bad english.. I'm from Norway!

Nothing inbetween the battery/board. As I said...it's fine for me...it's up to you if you wish to risk it, i can't be held responsible for it

It doesn't survive cranking, unfortunately, i'm currently using it as a "stop-gap" til I can be bothered to get myself an Opus! However i've got another car to get on the road also, so i might be using it for a while longer

Hmmm.. 55W.. If i were to put a fuse in there, do you think 5A will do it? Actually, (Probably like any other person on this board, who don't already own one) I also want an Opus...

Anyway, this inverter is really getting on my nerves, so I guess I'll try to do like you did..

Any pictures?

The "brick" PSU that comes with it gives out IIRC 4.58A (or similar), so a 5A fuse should be OK. If it blows straight away...then you'll need a 10A

No pics of the PSU itself...but my install is detailed here

Oh yeah, I forgot...welcome to the board! Hope you enjoy your stay here!

VERY nice and clean install!

Think I'll just go for a 5A.. This way i can have the "brick" PSU in my office, and voilà - one piece less to carry with me in.. plus I can get rid of that stupid inverter (which is modded with a fanmate (voltage reg.), but still makes alot of noise!)

..

Thank you! I'm sure I'll enjoy my stay.. I've been lurking around these pages around 2 years (since i started my project).. Such a great collection of information!

Also, thanks for your very quick and helpful replies!

Typically, you would use a fuse rated at twice your expected load.
So, I would suggest a 9A or 10A fuse.

Really? The psu is 55W (?), Though I don't expect it to be fully loaded.. M-10000 board and Western Digital 120gb.. Guess I'll try with 5A first, and if it blows....

That WD drive will take a large chunk of the power

And remember, if it's wired directly to the battery, then it will send whatever voltage the PSU recieves (typically about 13-14V) into the hard drive.

I am not having any problems as of yet doing this, but I'm getting an Opus soon as I don't trust it 100%

YMMV, of course
