Phanteks Power Combo harnesses the power of two PSUs

[HEXUS]

Imagine linking two 1,200W PSUs in a single system, says product manager Boon Tuoh Khor.

Watch the show..

Could work as a DIY christmas lights power source.

Such devices have been around for years.

In a world where SF make a stunning quality 2000w psu I'm finding it hard to see a place for this...

I can see one possible avenue, for the builder who wants to upgrade their system (say put in another video card) and have not quite enough power to run two. So to complete the job cheaply, they could get a second small PSU.
A usual wall socket will only supply 2400W (240V with a 10A fuse in Australia) and you still have to power the monitor(s), speakers, and other equipment plus anything else on that particular circuit. So you would have more to sort out than just putting 2 big wattage power supply's in a PC. We had some special separate circuit wall outlets put in with 20A fuses, just to power the PC's and the rest of the extras (one room is a office with multiple PC's plus extras, and the other is the Gaming/HTPC plus TV and extras in the entertainment room).
