It is time for me to replace my current system. However, the days of my building my own systems are in the past, other than adding a few peripherals. So I want to purchase a pre-built system. I've been looking at this system:
Other than what's already in the system, I want to add two PCI cards for a phone modem and a wireless NIC. I also have a portable USB hard drive that, when I connect it to the system, will draw its power entirely from USB (it does not have an external power source). With this in mind, the thing that concerns me about the pre-built system is that it has only a 300w power supply.
Do you think I should be concerned by the power supply? And instead look for a system with a more powerful power supply?
