500 for a few months. Not nesc. a statement about the board, just my symptoms and a question to the group about theirs. It could be that one of the older kits had degraded slightly and the new one just needs more by default. It could also be change in PSU I suppose. I also have a fresh Corsair 1000hx on hand to setup. We'll see. I don't really care what it is as long as I can pin it.
