I use an Xbox in mine, so the benefit of the smartstrip (which I use) is keeping the Xbox supplied with a constant flow of power, so that I don't have to reset the clock every time I boot it up.
Does it matter if the clock is wrong? I read that when modding it is a good idea to keep the clock correct, but personally I don't want to supply power to mine constantly.
Actually...
It doesn't really matter much at all with the mod turned on, because it checks with a time server on boot, but with the mod off, it forces me to the time/date settings at the dash on start up. Not a big deal, but annoying all the same.
Another thing with the Xbox, is that it doesn't automatically turn on when it receives power, and unlike a PC, it can't be changed to do so in bios settings.
With the smartstrip, I just have a power button for my Xbox routed to the underside of my control panel, and I can easily turn the cab on and off from there (Downside is that my 2 year old is shorter than the bottom of my control panel, but that problem will be taken care of with a little time. lol). Plus i got the smartstrip from a supplier that was clearing em out, so it was as cheap as buying a regular surge strip.
