Hetai Tech 500W ATX Power Supply 120mm LED Fan 24 Pin SATA

SKU CH-KHC0-BY30W

Delivers 250 W continuous power with a 120 mm LED fan and SATA connectors for desktop builds

  • TypeMount
  • 500 W peak power handles demanding desktop builds
  • 12 cm hydraulic-bearing LED fan runs quietly at low temperatures
  • 80 % efficiency reduces waste heat and electricity cost
  • Manual 110–220 V input switch suits global mains voltages
  • Full protection suite guards against over-voltage, over-current and short circuits

Product identity

The Hetai Tech 500W ATX power supply delivers a peak output of 500W with a continuous rating of 250W. It targets basic desktop builds that need standard 24-pin, 4-pin, 6-pin, SATA and peripheral connectors. The unit operates on manually switched 110–220V input and meets the ATX 12V specification.

Sustained load behaviour

Continuous output is rated at 250W with 80% efficiency, so extended workloads stay within that envelope rather than the peak figure. A 12cm hydraulic-bearing LED fan runs under intelligent temperature control, adjusting speed automatically to manage heat and noise during prolonged use. Protection circuits guard against overvoltage, overcurrent, overload, undervoltage and short circuits.

Installation practicalities

The aluminium-alloy shell measures 15x14x8.5cm and includes cables of roughly 140cm total length with output leads around 50cm. Manual voltage selection must be set correctly before connecting to mains. The fixed cable bundle provides 1x24-pin, 1x4-pin, 1x6-pin and two combo cables each carrying a 4-pin peripheral and a SATA connector. Builders needing more SATA or PCIe plugs will find the native count limiting.

Questions about this item

How loud does the 120mm LED fan run when the 250W actual power supply operates all day?

The 120mm hydraulic-bearing LED fan uses intelligent temperature control to adjust speed automatically, keeping noise low during continuous operation at 250W actual power.

Which cables must my build already provide for the 24-pin, 4-pin, 6-pin and SATA connectors on this unit?

This power supply includes a 24-pin ATX, one 4-pin, one 6-pin and two cables each with a 4-pin peripheral and a SATA plug, so your motherboard and drives simply connect to them.

Will the manual 110-220V voltage switch work reliably with older components that draw power from the 12V 16A rail?

Yes, the manual voltage selector handles 110-220V input while the single 12V rail delivers 16A, providing stable power for legacy parts that rely on that rail.
