Powering Internal and External Devices

See the specifications in Chapter 2 to determine whether the D4–470’s internal power supply is adequate to power internal accessory devices. Use external power only for CD–ROM drives and other external devices. The D4–470 power supply is not designed to power external devices.

Changing the CPU

Because of the range of choices and the complexity of setup when you change CPUs, we are unable to offer technical support or warranty coverage in the event that a CPU change is made.
