What are my options for ATX PC

**ligergtt** · 04-09-2006, 07:03 AM

Hi all,

Just wondering if someone who knows their stuff when it comes to electronics can help me out with how to power up this PC. I know how to build pcs fine but never paid attention during physics and learned about all this V i R stuff.

I'm thinking of getting a 600W invertor to run a 400W power supply in my pc. I've heard a lot of good things about this Opus PSU but heard its also only limited to 150W.

What I wanted to do was get a 600w invertor, run it through a shut down unit and then power my pc from that. But I dont know how to draw a diagram for it or know waht fuses to use. Could somone lend me a hand?

FAQ: Will <insert PSU model> Power Supply work with my system?

Yeah read that already, I think I'll need more that 144w as that seems to be the max the DSATX offers:

DSATX
12v rail = 12A (144w)
3.3v rail = 10A (33w)
5v rail = 12A (60w)

I like the features on the opus, how it cuts power to the pc when the batterys levels get too low and how it puts the pc into standby when the ignition is off. Is that because of the SDC inside it?

Is it possible to have a SDC with an invertor for a 350W power supply in a normal pc?

It might help to know what the specs of the PC that you intend to put in your ride.

Remember that the 144w is only the 12v rail.
Realistically, if you build a PC that's pulling more than 144w on the 12v rail, it's far more than anything you'd ever need in your vehicle.

Yes, you can use an SDC with an inverter. It's been done before.

Umm...You do know that the DSATX does these things also (low voltage shutdown and shuts down with ignition).

DSATX is rated for 220W whereas the Opus is 150W.

BTW I'm using a DSATX to power a P4 2.4GHz, 512 MB RAM, GeForce3, 3.5" 40GB 7200RPM HD, full size DVD-ROM drive, USB GPS and 7" Xenarc touchscreen.
