All squirreled away within a nice little cabinet are the following components of my entertainment center:
- Pentium-4 based (vintage ~2002) PC
- Samsung 32" LCD HDTV
- Netgear Ethernet hub
- XBox 360
- A huge surge protector, to which all of the above are connected
It's a wonderful and painstakingly configured setup, but the end result is a monster that sucks roughly 13 watts (via Kill A Watt) when it's just sitting there (i.e., everything in standby* mode). There is, of course, a switch on the huge surge protector, so I can reduce this drain down to 0 watts every evening with one flip of this switch, but I am concerned:
Does cutting the power to these devices on a nightly basis risk damage to any of them? As you can see in the list, all of these devices (save for the surge protector) are more-or-less computers, all with individual DC power supplies, so general advice regarding PC power supplies should apply. Right?
*When I say standby, I refer to the entire rig holistically, and that all of the devices are at as low of power use as possible without unplugging them. So the PC still has limited power to the mobo to check for the use of the soft power switch and wake-on-LAN, the TV is waiting for IR signals, the Xbox and Wii are listening for RF, and the hub is at full power (there's no off button period). Still, with everything "as 'off' as possible", it draws 13W.
