A 1500W switching power supply delivering multiple DC voltages from 12V to 90V with dual cooling fans in a desktop chassis
This new NShi server chassis delivers a 1500W switching power supply that accepts AC 110V or 220V input and provides multiple DC output options including 12V, 13.8V, 24V, 36V, 48V, 60V, 70V, 80V and 90V. It suits technicians and integrators building desktop servers or test benches who need flexible voltage rails in a compact 0.44-pound unit with dual cooling fans.
The 1500W capacity replaces smaller SMPS units that cannot sustain high continuous loads or lack the range of DC outputs from 12V up to 90V. The jump is worth it when your project demands simultaneous 12V, 24V, 48V or higher rails from one enclosure, or when dual fans are required to manage thermal load in a desktop chassis without external ducting.
Installation follows standard desktop chassis mounting; the lightweight 0.44-pound frame fits typical server shelves or benches and the dual fans draw air through the supply without extra brackets. What usually goes wrong is mismatching the AC input selector to local mains, so verify the 110V or 220V setting before powering on, and confirm the required DC output voltage is enabled for your load.

The supply is a desktop-type chassis weighing 0.44 pounds; verify your case depth and mounting holes before purchase.
Connect live, neutral and ground to the AC terminals, then attach the load to the 90V 16A DC terminals, observing polarity.
Clean dust from both fans every six months; replace a fan if it becomes noisy or stops spinning.
