Opus Alternative

**bgoodman** · 04-28-2004, 09:48 PM

I had asked Arise Computer For a quote on an ACE-865V AT Power Supply. When they responded to my inquiry, They informed me of a 100 Watt ATX DC-DC PSU for $79. I present you the MPD-810-ATX I was quoted $79. Seems like a steal for those of us tired of opus's delays

Interesting...If only I hadn't just bought the opus

dont spose u asked the price of the 6.4 and 12 inch vga lcds?

Input voltage: 10-30v. This may not survive a crank but for the price, looks good.

I own one of those - it is great 'cept it doenst survive crank on my 2003 A4 with a stock battery. Otherwise they are good stuff, especially for the price......Of course i had it hooked up to the radio harness power wire - which is 16 ga wire. But there is no cut in power when the engine cranks.....

just my $.02

Edit: I owe alot of credit to None, he helped me out when picking the Arise unit and when hooking it up. For $79 + the Muchas SDC for $35 i came in @ $115 for a 100 Watt PSU with auto shutdown/sttartup (with a bit of wiring). Search for his posts, he has been talking about the Arise forever.

i just can't understand how you guys drop to below 10 volts when cranking. especially the 4 cylinder guys.

could be that the guage wire i had caused an abnormal amperage loss @ the terminals and nothing woulda survived crank...i will know this summer when i run 4 ga wire to the trunk for it and the 500 watt amplifier....

What does this mean: "Total Output Power: 85 watts with no fan , 120 watts forced air" (copied from the site) Does it mean that if I just hook up a fan to it then it will kick out more juice? That seems....weird. Finally, another weak question, does this come loaded with the connectors to just hook to the mobo, hard drive and dvd/cd drive? (It does say 'ATX')

Yes, that's exactly what it means. Not weird at all, most IC regulators have a higher output with active cooling, since they generate heat in direct proportion to the amount of juice flowing through them.

Nobody pays attention to me except you, jusatry. I've seen you on Audiworld.

Hey, when a fellow member of the fine state of Utah says something I'm all ears! I understand the computer portion of this project but the electrical, and wiring part is were I get lost. I just don't have any experience with it at all. My education, like I said, it limited to putting the componants together and using the computer after it is built. Sorry for the silly question but thanks for the help! None, I belive that you are using one of these powersupplies right? (Based on another post) Successful? Again, did it have the connectors to just hook right to the hardware?
Thanks
