Thread: Can I power an Opus 120 at home with a 10 Amp Regulated Power Supply?

If it was a perfect world, the opus would draw a maximum of 10A. 120W = 12V X 10A. But in the real world, you would probably be pushing the limits of the 10A supply if the opus is fully loaded. Unless it is fully loaded, it should work ok.

I found that the best way of supplying power to the opus in the house is to use an old car battery .

Save the cash and just buy a cheap 300watt atx psu. And mod it to run without a motherboard. (greenwire to any black)

Well I already have this power supply. Will it draw more than 10A if I'm just running a 2.5" HD, PCMCIA wifi, and PCI card?

You running a MII 12000, right? Unless the PCI card is a big graphics card, 10 amps should be plenty.

My draw with opus 120 is 2.8A when playing music with DVD player and surfing the net using SMC 108mbit wireless USB + DFI G5M100, Pentium-M 1.8Ghz, 2 x 512 MB RAM, 80GB 2,5", Slim DVD+/- writer, Cinergy 600 PCI (radio on), + 3 fans.

It is steady at 2.8A, some peaks at 3.2A.

Thank you both for posting. Seems to be running fine so far.
(I gotta get one with meters)

You're welcome, of course. If you really don't need an adjustable, lab power supply, you can run to your local radio shack get something like this to measure the current: http://www.radioshack.com/product/in...ductId=2103176

Dude, you've got a meter to tell you what the Opus is drawing. Unless that meter pegs to the end of the scale, you've got nothing to worry about.

And if you *do* wind up with a configuration where the Opus is pushing 10A, you can always up the voltage to 15V. The Opus won't have any problem with this, and if anything it should run more efficiently.

Backspace does, but the original poster does not.
