4x Core switches with two PSU each using 1 to 4 Power split???

Reddit,

Building a new MDF and going over the power requirements. Currently we have 4 Dell S4148 Core switches that have two PSU's each. C13 to C14 Power cables.

Curious to know if this is smart or stupid. Since there are two redundant PSU on each switch, and we have two circuits with two PDU's on each side of the rack, would the following one-to-four power cable be OK to use ONE slot on the PDU to feed 4 of the Core switches?

The following Amazon link is what I'm considering purchasing, thoughts?

I figured, nobody should be unplugging power cables anyway, this would allow the cables to look SUPER clean and labeling would be a breeze. The catch though... it's only one cable to four switches, however, it's also the same on the redundant side. Is it really that much of a concern? After all, that ONE PDU only has ONE cable going to the ceiling.

tl;dr - one to four C13 to C14 power cable smart or stupid for Core switches? and... really any 'pair' of devices?
