High Efficiency 2450 Watt Server PSU for Two (2x) Antminer L3+ with Ready-to-Use Wiring. This model AMP2450L2 has been retired and replaced by the more compact AMP2400L2 and AMP1100L1. Thank you for your support! No more flimsy breakout boards!
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!
Value : When you add it all up, we come ahead of any breakout board (and way ahead of Bitmain's own power supplies). And now, onward with the technical specifications: Load Specifications. Two Antminer L3+ / R4.
Two Antminer D3 or Avalon A741 at full load. You can power other miners S7/S9/A6/SP20...
Etc with this PSU - but we have models specifically designed for these jobs (see our other listings). 2450 Watt HP server PSU. 8ft heavy-duty C20 power cord is included/integrated. Please specify if you need another plug type e. NEMA 6-15, NEMA 6-20, C13...Dual groups of ten (10x) 16 AWG braided copper 6-pin PCI-E Molex connectors, each rated to 240 Watt / 20 Amps at 80 degrees C. 30 in (75 cm) wiring length. Wiring soldered to the power terminals (minimizes electrical and thermal resistance). All energized contacts fully insulated and protected against wear, tear, and heat. Value Comparison: Here are your options for powering up bitcoin/altcoin miners.
Use Bitmain's ready-to-plug APU/APW supplies. After you've screwed all the pieces in, your cost will still be higher - and breakout boards have inferior reliability and safety. Use consumer PC ATX power supplies.
They suffer failure and wiring meltdown at high rates. In comparison, our integrated-wiring PSUs provide the best performance/cost and are ready to use (which is why we use nothing else in our mines). 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. 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. 14 or 12 AWG cannot be reliably crimped to the pin, resulting in local overheating and burnout.
Bigger is not always better! We use quality PCI-e connectors with proper crimping. The weakest part of the PCI-e power link is the pin boot where the wiring is crimped. This is where overheating and burnout starts.Our PSUs ready to plug and go. You will not waste your time screwing around with DIN terminals or spade connectors. Please make sure your AC wiring/breakers are rated for the electrical load of the PSU. 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.
