Ok, i've got some cash (but not loads) and wanted to get a DC-DC PSU to get me started with one of my low spec computers (less power requirement) that i've got hanging around. So, i looked in the MP3CAR store and found they are too expensive, but I can appreciate this as you will indefinately receieve better service and quality of parts. However, i've found on eBay an unofficial M2 claiming 150W: http://cgi.ebay.co.uk/Mini-ITX-M2-Ca...item1e59848945
What are people's general opinions? I've read good reviews elsewhere on these eBay ones, but just wanted to see what the pro's thought.
I thought i'd get that answer Do you know a rough guideline power consumption for your usual Intel ITX boards and maybe 3 usb devices + 1 hdd and + 1 DVD? I mean i can't see it being huge. I mean this is generally only to bench test a system with my custom front-end until i get a new car and maybe XPe. Means i can check the start-up and shutdown features.
If you are running a low power system, then the M2 should be fine. I wouldnt feel comfortable running anything over 50W off of the M2, since it has been known to take out the entire system when overloaded. Alot of people dont like the M-series power supplies because of this fact, but if you have everything setup properly then I wouldnt worry too much about it. My only complaint with the M2 is that the voltage on the +5v sags very easily. Adding a small wifi dongle to my USB hub drops the voltage by 0.1 on the +5v rail.
i agree, i had plenty of usb problems when i ran off motherboard ports. even if you just have a few usb devices, i strongly suggest building a powered usb hub...
Sounds like i might be in for a ride then... What other power solutions are there? as i thought the M# series were standard for car installations. I was considering powering the drives (HDD/DVD) from a custom supply. Even with the USB devices, realistically i'm only then looking at about 40W for the setup running, if i power the HDD and DVD seperately. Thanks for your comments so far.
I don't know if your interested, but i noticed opus 180W psu's for sale on ebay for $50 buy it now. I read the seller's feedback, and all the psu's received good feedback. apparently for some reason he's selling about a hundred of them.
just a thought. I just ordered a m2-atx from mo-co-so for only 69.99 though, i still didn't want the risk of a used product, even though opus has such a good rep. plus i'm only running a via cpu, so my power consumption will be very low!
I couldn't find the Opus ones you mentioned. Linky? I'm in the UK too btw, so hopefully shipping won't be too much.
