I'm trying to see if the PW70A I have will run everything... total amperage with the desktop HDD, desktop DVD-ROM, and lillilput 7" is 2.21amps on the 12V rail, and 2.1amps on the 5V rail. I also have the following to figure in- 2 powered usb hubs, gps, usb flexible keyboard, ps/2 glidepoint and usb wireless network. Will the PW70A hold up, or is it time to get an opus?
If you're planning on using that system it would be worth your while to get an OPUS.
The PW-70 doesn’t regulate the 12v power rail. You would also like the startup/shutdown regulations that the OPUS does.
