Why PDUs Don't Always Make sense

I thought I'd post this to illustrate the challenge when trying to run multiple ASICs of off standard server PDUs.

The left is a single 14TH S9 on one bank, and then a 13.5TH S9 and an S7 4.73TH on the other. On the right are two M3s, one on each bank. So 5 ASICs on two server type PDUs with 24 outlets each, big waste.

How many of you guys have experience with www.bitcoinpowerstrips.com? Looks like they do not have switched, but at least they are a better fit for ASIC miners.

I dont quite understand this post. Who cares if you have a bunch of empty sockets as long as its working?

It was really for the rare occasion someone uses the search feature. PDUs, unless you can get them really, really cheap are not feasible. Especially if you start looking at switched and metered. The fact that it takes 2 PDUs for 5 miners is crazy. So again, economics.

I also wanted to see who, if anyone, had used the PDUs I linked. They are not switched, but *seem* to be built to handle much higher loads.

What do you guys use at scale? I breaker per miner? Or are commercial codes different where you can have multiple 220/240 outlets per breaker?

I built my entire datacenter off of secondary market PDUs because its just not feasable at their MSRP.

I use 3 phase power so my setup will be different from single phase as far as breakers and layout is concerned.

I would understand if you'd rather not share, but if at all possible I'd love to know your 3 phase setup and how it relates to PDUs (please mods this is on topic!). Believe it or not my house built in 1954 has 3 phase. My sub-panel is only single phase, but I have been thinking about a new service on my out-building that would house all my mining equipment.

You are looking at pdus all wrong.

Buy used on eBay .

I understand the idea of a 75 amp seems cool but I would not go that route.

Hp makes a four socket pdu for 30 amp circuits

Runs 4 s9s with ease.

I get them on eBay for 35-50 dollars.
