None, wrong voltage.
The SMPS400 is fit for them. How many? I dunno, supposidly 6, but I'd just contact Hypex.
Incorrect. The SMPS1200A180 (lower voltage) version is perfectly fine for the UcD180 modules.
Probably six modules. But it could be more depending upon the load distribution on the various amplifier modules. Eight would most likely be fine.

They've got an incorrect PDF then.
There's nothing wrong with their PDF's.
The SMPS1200A180 is spec'd at +/-46VDC and the UcD180 modules are designed for voltages between +/-30VDC and +/-50VDC. It's a perfectly acceptable combination.
I tested an SMPS1200A180 module a few months back so I know of what I speak.

I didn't designate a version either, but I immediately found the appropriate datasheet with voltages for all three versions listed.
http://www.hypex.nl/docs/SMPS1200_datasheet.pdf
And the page in their web-shop with the 180 version listed, noting that it's designed for their UcD180 modules.

SMPS1200 Vaux power supply fault problems
Question: anybody run into the issue that when you inadvertently short Vaux (either polarity) in unregulated mode it instantly kills the source? Seems there is absolutely no overcurrent protection at all. If you accidentally do this in a completed amp project (like with nCores), you're done - you have to replace the entire SMPS unit.
