Crap.
The fans I have are 0.96W, and I don't have any power resistors remotely large enough. According to this site (http://makezine.com/projects/computer-power-supply-to-bench-power-supply-adapter/), a 10R resistor at 10W across the +5V and Ground is enough for most PSUs. But it looks like I can also test it with the fan in there first to see if it does generate enough of a load. If it shuts off, at least I wont be damaging the PSU, right??
The next thing I've just noticed is that the wires coming off the new heatbed are quite thin. I measured the resistance, and it's a solid 1.5R, so by my calculations, that's 8A. Based on my earlier diagram of using the SSR, I'm wondering if those thin wires from the head bed will be thick enough to take 8A. This is them compared to some of the ones I've trimmed from the PSU:

The black/yellow are the PCB, the purple/grey were cut from the PSU.
