It's borderline trolling. Is that a good thing to you somehow?
I post opinions and suggestions based off of my personal experience, can't help if people don't find them useful.
You can easily find a lower wattage PSU for a small home server/htpc type setup. Also, just because a PSU is rated for 400W or what have you, doesn't mean it's constantly pulling that amount of power. For example, my home server/htpc (with 4TB storage) is based around a 300W PSU. From the wall at idle, only pulls 25-30W, at load it doesn't go over 140W!
