Some pictures of our mining rig Grin

Do not you have enough money from your pre-orders to buy some PDUs? Hope you don't burn the warehouse with all the rigs inside...

This is one lame and unprofessional setup from a H/W manufacturer...

It's electrically correct for a 3-phase system even for north american standards.

Why on Earth would you think they would use PDUs? they are limiting in a high power usage environment plus the cost is horrific compared to Rack mounted Switchboards.

- PDUs

Most PDU manufactures max rating is 32amps.

Those miners are 1600w each.
9*1600 - 14.4kw per rack.

At 230volts thats 62.6amps per rack.

So 2x 32amp PDUs required....

Wholesale - 1k each atleast.

- MCB's

1X Schneider Electric 3 Ø Main Switch will a Standard 64amp 230/240 Volt. - $122 from our local electrical supplier.
10X Schneider Electric MCB 10amp 230/240v breaker - $4-12 each.
1X Schneider Electric Inline watt meter - $26
10X IEC320 C13 Plugs (Jug Plug) - $1.2
1M Din rail

About 10 bucks in flexi cable

Roughly $220 bucks all up per rack, Thats 10 racks outfitted with Switchboard Mounted racks vs 1 outfitted with 2 PDUs.

Logic ....
