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?
NO!!!!!!
It is a switched mode(SM) power supply not a wall wart Iron cored bitch, as you increase the loading the Switched mode changes its operating parameters to meet the requirements. NEVER use an Iron cored transformer in such a situation, it is a MASSIVE waste of power .
What DOES happen, as you increase the Capability of the SM power supply the Base wastage figure increases.
So it may be that with NO load 2*400W actually consume less power than a 1*800w, basically it comes down to the leakage of the switching transistors and the Inductors. BIGGER inductors are more wasteful.
This is where the difference between the CRAP you can buy on Ebay comes in, Normally such crap is made from the components that do not meet the specs for high quality SM power supplies.
I.E switching transistors that are so leaky that they sell under the "Titanic" brand name.
