SSD's draw substantially less power than a mechanical/rotating hard drive.

All mechanical drives draw off the +12V rail; SSD's generally only use power from the 5V (or 3.3V for newer mSATA) rail.

Indeed switching power supplies may generate more hash without a load on a particular output line.

It used to be the case for some DEC Q-bus computers, if you didn't have enough hard drives plugged in to your system, there was a dummy load card to keep the switching power supply tamed.
