That pdu has 4 jacks each one uses c19 to c20 cables.

Each jack can handle 12 amps . But the master circuit is 24 amps.

If your psu are 240 volt and use c19 to c20 you can do four of them . Each one can pull 1350 watts no issue.

So a eight card 1070 rig set to 120 watts a card will pull 1050 watts. Using 4200.
That is 32 1070 set to 80% tdp.

No extension bar limits you to four psus but if you set to 120 watts you are all good

If you push to 135 watts or 90% for each card

It is 1170 a rig. That is 4680 watts

Stupid question, In both your previous post, your calculation did target 5400Watts almost and why is that so?

I know with a 30A is derated 24A to avoid overloading the socket, hence why people opt for the 240V to create room for the maximum amount of rigs or GPU's. Please kindly clarify any information I might have misunderstood.

So are you implying that I can't use all the available wattage on the 24A PDU, because on a 30A circuit the 24A PDU is derated already to give room for the 80% max load on the circuit. I may be wrong 100%, I'm just trying to learn about as much as a can when it comes to Mining and its best electrical practices.

On a side note, I found a similar PDU with 6 C19 outlet, where each bank of 2 outlet can support up to 13A. Here's the link for the PDU

My hopes is to find a way to use almost all the wattage I an get from the 24A 240V and if that would mean going for a PDU that's 30A 240V but derated to 24A as long as let's me use 23.8A, that would be totally cool. I don't have more that one of that 30A 240V in my apartment, so I'll definitely like to leave as less on the table for waste out of the 24A that's the safety limits.

My PSU's are EVGA, I read in your fifth thread that they'll take either 120 or 240. Also, trying to work out how i can fit the HP or Dell Server PSU in a 4u case rather than standard ATX PSU, suggestions are welcome and needed.

You are lost . So here goes.

220 to 242 is the range of most 240 services.
I am being realistic and trying to keep you safe.

I have found running at 23-25 amps causes shut downs. Why simple if you are pulling 23 amps at 240 volts what is your watts?

About 5520.

So what happens if volts sag to 220? Amps rise to about 25.1. And you pop the master breaker since it is 24 amps.

As for the six plug pdu IIRC. It is a 3 phase and not good for you . I picked one I know will work and I gave you safe settings for it.

Are you looking to set your cards to 100% tdp of 150 watts.

8 per rig = 1200 add 100 is 1300 x 4 is 5200

I would not set this way .

Tell me your cards again and exact make. Model along with how many you have.
