Well I wondered if the on-board card needed a power boost, but it's going very well without.
It's so strange that it exactly fits the main power strip.
It can be seen in the top picture marked 4P. and an odd mixture of voltages.
BTW, does the memory come with those blue plastic encapsulations- held on with chrome clips - or are they an accessory?
G.Skill Looking again, they may be metal.
