OPUS to External DVD Drive & USB Hub

**Rith** · 05-31-2004, 01:35 AM

Ok, This may be a stupid question, but can I power the DVD drive and the usb hub from the opus 150 PS (both of the items require more power then just the usb can handle to work properly).and if so, how can I do this. Thanks

Okay. I'm no expert at this, but this does apply to my plans. So here's my theory:

The external USB case that I'm gonna use has a transformer that converts 110-240VAC to +5V and +12V (both at 1.5A). The power supply outputs that already so there would be no need for the transformer. The connector has 5 pins so it should just be a matter of taking a multimeter and figuring the pin out. I imagine you don't wanna be cutting up your power supply so I could recommend taking a harddive connector and making this into you power adaptor. I know +12V is running through there but not sure about the +5V. I imagine it would be. You should see four wires. Yellow, Black, Black, and Red. The blacks should be grounds and the red and Yellow (I think) it +12V so I'm assuming red will be +5V. Another thing for the mulitmeter. Make sense?

Check your USB hub. I'm going to assume that it is probably +12V. You may be able to tie this right into your vehicles power but it would probably be better to run it through the power supply.

This is my opinion and I would be willing to try it myself (I probably will once I get closer to installing). What does everyone else think?

yup, actually most usb hubs are 5v.

Good to know. I have an old USB1.1 that runs at +12V.

Im really new to all this 12v 1A.. and whats it all about. (Iknow its 12 volts and 1 amp) but I mean how am I supposed to connect a device like the Audigy 2 nx and hook it up to the PSU. What connecttions do I need? Adapters ect... Soory im such a nub at this powering stuff, but I have to power 3 devices liek this and I have no idea how (Audigy 2 nx, external usb2.0 slim dvd drive, and the usb hub)

Both my external slimline DVD/CD-R Drive and USB 2.0 Hub run on 5V, so I patched them into a molex connector and am running them off my 150W Opus with no problems... buy a multimeter and learn how to use it, it definitely has helped me!
