Yes, I contacted the Kiwitechics guy (Murry) asking if his power supply gave more capacity than the new one (or just more reliability because it's new). He gave a very prompt reply saying that he thought that the polysix had such good heat sinking (ie, the entire metal panel) that he didn't think that I should have a problem drawing more power from the stock power supply.
Given that he basically just talked me out of a sale, his reply seems pretty authentic. I worry though. Perhaps I didn't fully explain how much extra power I was drawing (which I hadn't quantified at that time). So, I dove in and did my temperature measurements and started this recent thread.
For some reason, I thought that Murry stopped in around here from time to time. I expected him to chime in, given his interest and expertise in the Polysix and its power supply. If he hasn't seen the data, maybe I should shoot him another email...maybe he'd be interested and would be willing to his thoughts...
