Graviton GZM-U60S12 12V 60W server power supply

SKU CH-3P1A-57GNG

12V 60W server power supply accepts 100-240V AC input with passive PFC

  • Reliable 60 W output for 12 V server loads
  • Wide AC 100–240 V input suits global racks
  • 12 V 5 A rail delivers steady DC power
  • 80 PLUS certification confirms tested efficiency
  • Passive PFC keeps design simple and robust

Compact 12 V 60 W server unit

The Graviton GZM-U60S12 is a new switching power supply built for server and desktop chassis that require a single 12 V rail. It delivers 60 W of continuous power from a 100-240 V AC input with passive power-factor correction. The non-modular design keeps cabling simple for fixed backplane installations.

Thermals and power draw

Passive PFC and a 60 W rating mean the unit draws up to 1.5 A at the AC inlet while supplying 5 A at 12 V DC. Efficiency is certified under an 80 PLUS programme, so typical losses stay modest during normal server loads. Fan noise will depend on the host chassis airflow rather than the supply itself.

Replaces lower-capacity 12 V bricks

This supply steps up from smaller 12 V modules when a system needs the full 60 W envelope for additional drives or expansion cards. It is not suited for builds that require multiple voltage rails, modular cabling or active PFC for higher efficiency targets.

Questions about this item

How is the GZM-U60S12 mounted in a server chassis and what step is often missed?

The unit fits a standard server PSU bay and connects via its fixed output cables; the step often missed is verifying the AC inlet voltage selector matches the local mains supply before powering on.

What maintenance or replacement will the GZM-U60S12 need over time?

The internal cooling fan and electrolytic capacitors are the primary wear items; expect to clean dust from the fan intake regularly and plan capacitor replacement after several years of continuous operation.

What limit appears first when the GZM-U60S12 runs at full load continuously?

The 60 W output ceiling is reached first; drawing more than 5 A at 12 V will trigger over-current protection and shut the unit down.
