You're welcome.
I run all of my printers with used HP DPS-600PB server power supplies. I power a Raspberry Pi, the RAMPS board (VCC) and the RAMPS servo bus (+5V) direct from the 5VSB on the power supply, with three separate wires back to the source. This way, the electronics are always on. I switch the power supply on and off using the PS_ON line from the RAMPS power header, so the 12V bus for the motors and heaters is only on when needed.
I'm running an industrial silicone heater pad under borosilicate glass on my 12", and it delivers a lot of power. I have to use borosilicate because ordinary glass explodes during the fast warmup cycle.
