PSUs and molex connectors are great, i'm sure, but I for one do not have a pc to use with my bASIC. I will be using a RPi to host it, so molex and PSUs are out of the question.
I suppose I will wait for you to specify exactly what kind of dc adapter we will need.
Using a Pi doesn't stop you using a PSU. You don't need a PC to turn a PSU on.
My concern about PSUs is I only have a 900W and a 850W. I'll be running 1x54G 1x24G 1xBFLSC 1xBFLlilSC.
I can only run the bASICs off the PSU, so I think i'll end up running them from the wall, with clunky US>NZ adaptors.
Do you waste power using 900W to power 200/300W only?
They're usually most efficient around 50% load, but using the 850W will still be more efficient than using power bricks.
