A 2000 W desktop server chassis with three-proof coated circuit boards, silica-gel protected high-voltage circuits and EMC/EMI shielding
The NShi JLN-2000A is a desktop server chassis equipped with a 2000W ATX power supply designed for multi-graphics card configurations. It targets builders assembling high-density mining rigs or compute nodes that demand sustained high-wattage delivery. The unit uses a metal shell for structural rigidity and heat dissipation.
The metal fuselage acts as the primary heat-dissipation path, while the PCB is coated on both sides with three-proof paint for moisture, dust and corrosion resistance. High-voltage sections are fully encapsulated in silica gel to prevent conductive contamination. An EMC/EMI circuit is included to reduce electromagnetic interference during continuous operation.
The power supply passed a four-hour aging test at an ambient temperature of 45 degrees Celsius. Protection circuitry covers overcurrent, overvoltage, undervoltage, overload, short circuit, input undervoltage and overtemperature conditions. Output cables use standard copper 18 AWG wire and the 6-pin connectors feature gold-plated terminals for stable contact under heavy load.

Mount the desktop chassis, connect the 18AWG output wires and the gold-plated 6PIN interfaces, then verify the silica-gel-covered high-voltage section is seated before powering on.
The three-proof paint on both sides of the PCB and the Japanese long-life capacitors are rated for long service life; periodic dust removal from the metal shell is the only upkeep.
Overtemperature protection triggers if the ambient temperature exceeds 45°C during continuous 2000W output, shutting the unit down until it cools.
