Cluster of 15 Raspberry Pi power supply

Hello Everyone,

I need to create a cluster of 15 Raspberry Pi for this purpose I should consider a proper power supply. Since each single Raspberry Pi 3 Model B+ using 5V/2.5A DC power input, therefore, to the keep feeding my Pi the steady 2.5A it needs for proper performance power supply. Simply I should consider 15*2.5 = 37.5 A for highest performance (If I need fully loaded Pi).

Now I want to know is there any suggestion to power up this cluster with the available power supply in the market? Because I found a couple of solution to make my own power supply but it cost me a lot and I'm not quite sure how it will perform.

I hope I could explain my problem in a proper way.
Any suggestion will appreciate.

I would recommend a ready made commercial power supply. Something like this, though it's not a recommendation -

You might want to make sure you have enough amps to run hard disks and other peripherals as well as the Pi's themselves.
