Smells really fishy to me. 300W and no aux power connectors on the board? Can't even render the PCB correctly. It's mirrored and then photoshopped some labels on it, which look non-mirrored.

"Invested" billions of whatever currency in it and call it a "GMO"? Come on!

Edit: Those black power converters don't belong on a 300W ASIC board. They are nice and expensive and very efficient, but are not intended for high current/low voltage applications. Proper VRMs are needed for anything >50W.

This is what they look like. Note that the Linear Technology logo is easily recognizable on the "GMO" product. I call it utter BS.
