Today I picked up a few Dell D220P-01 Power Bricks (for free). They caught my eye primarily because instead of a standard laptop charger plug on the end, they had (what at first glance) appeared to be a PCI-E 8 pin plug. Further research shows that it is keyed and wired differently (more on that below) but I have googled around and there were quite a few people using them on RC battery chargers with great results.
You can seem from the above pics it looks like the physical pins are reversed (on the clip side of the plug the pins are square, angled, angled, square with those pins being ground vs power) so definitely not compatible.
So, my question here is, has anyone messed with these power supplies before and used them to power a 160W Pico PSU? Seems like a simple mod to do -- most of JohnyGuru's complaints with PicoPSUs tended to be the crappy 12V bricks that weren't efficient, which is why he favored a 19v charger approach.
Second, has anyone had experience wiring up an adapter like this to a GPU? I know we've talked about dual brick setups (and I am not a fan by any means, don't get me wrong) but I am curious from a science POV. Seems very simple if you aren't worrying about stepping down voltage and the brick can handle the voltage spikes. I found some forums posts from 2009 where someone was able to do it and it seemed pretty simple in concept.
