1200 Watt Server PSU for Antminer L3+ (on 110V) or L3+/Avalon A741/D3 (on 220V)

No more flimsy breakout boards! No more melted wiring! We are experienced bitcoin miners/engineers who offer you power systems we know to work well in actual use:
  • Reliability: Our wiring and PSU choices have proved themselves in 24/7/365 harsh condition operations at 100% duty cycle.
  • Ease of use: No screwing around with din terminals and wire strippers. Just plug it and turn it on!
  • Quality: We work with a leading cable manufacturer to custom-design and make our wiring.
  • Value: When you add it all up, we come ahead of any breakout board (and way ahead of Bitmain's own power supplies).
Free shipping - satisfaction guaranteed - 60 day warranty. And now, onward with the technical specifications:

Power Supply Specifications:
  • Runs on both 220V and regular household 110V outlets.
  • On 110V output is 900 Watts (sufficient for one Antminer L3+)
  • On 220V output is 1200 Watts (sufficient for one L3+ or Avalon A741 or equivalent)
  • High efficiency (92% gold)
  • Compact 1U form factor
  • Universal C13 "computer/monitor" power socket
  • Universal Amity Labs 10-connector PCI-e harness  
Universal Amity Labs 10-connector PCI-e harness:
  • Designed to connect to any Bitmain Antminer (and other brands such as Avalon)
  • Ten (10x) 16 AWG braided copper 6-pin PCI-E Molex connectors, each rated to 240 Watt / 20 Amps at 80 degrees C
  • 24 in (~60 cm) DC bus implemented with 200C silicone heavy gauge wiring, rated to 1200 Watts / 100 amps
  • Wiring soldered to the power terminals (minimizes electrical and thermal resistance)
  • All energized contacts fully insulated and protected against wear, tear, and heat with high-strength dielectric epoxy shield
Technical Notes: There is a reason why you'll not see a single breakout board in our data centers!

  • Modern bitcoin miners require ~100 amps of current at 100% duty cycle
  • The PCB of most breakout boards does not have enough copper planes to carry such currents. The result is overheating, delamination, and equipment-destroying burnout.
  • The backplane connector of many breakout boards is a cheap low-current part instead of the 50-Amp-per-blade OEM version (check the part # rating on the Amphenol/Digikey parts site)
  • Breakout boards have all their hot points exposed. Drop a coin, a screwdriver...etc - and watch what happens.
  • A good server PSU will outlast the breakout board and pretty much anything else in normal use. An interchangeable connector is moot.
In contrast, our design optimizes heat management, hardiness, and insulation:
  • We solder the conductors to the power terminals, providing for absolutely minimal resistance and optimal heat conduction/dissipation. The solid contact also protects against accidental disconnects, contact sparks, and interface oxidation.
  • We insulate every hot point with hard electrical epoxy and heavy-duty shrink wrap to prevent accidental shorts and increase hardiness.
  • We use proper wiring gauge and insulation
  • We use quality PCI-e connectors with proper crimping
  • Our PSUs ready to plug and go. You will not waste your time screwing around with DIN terminals or spade connectors.
Ordering:

  • Free shipping only to the "lower 48" contiguous US states. Non-US buyers - please contact us before purchase for shipping quote.
  • Volume buyer? Please contact us - we can customize your order to your exact data center needs.
Because this is a custom modification of an existing device, the original FCC/UL/OHSA...etc PSU certifications are not applicable, and no safety guarantee is made.
