be able to add the drive as they consume a small amount of power. I'd be very surprised if it couldn't. From the specs, I don't think you have any power hogs in there, so a DVD drive should be fine. What GPU and Processor do you have, btw?
A friend of mine wants to add an internal DVD-ROM drive to a system that is a few years old. The system is running Windows XP Home with 768MB of RAM, a CD-RW drive, hard drive, add-on video card. How can we determine if his power supply is adequate to add the DVD-ROM drive?
