im working on some driveway arches and while I'm still confused if I totally get the power injection setup correctly (waiting for replies in a different thread) I know I'll be needing at least one extra power supply. Just curious what the preffered brand(s) are. Also, is a weatherproof one any better than a standard one in a good enclosure? On that note, any favorite enclosures? And just to make sure I'm not confusing myself any more than I already am, it doesn't harm anything if you have a higher wattage PSU than you actually need, right? I'm pretty sure I know that answer is that the wattage is just a measure of what the PSU can put out so if you get a high wattage PSU and just demand a fraction of that, it won't harm anything but is a little wasteful. Just trying to make sure. This whole power injection thing has me thinking I got it one minute and totally confused the next. But, as I said I'm working on that one with a lot of good help in a different thread so far.
