  • TypeATX
  • Modern Standby compatibility for extremely fast wake-from-sleep times
  • 80 PLUS Gold certification for lower power consumption and cooler operation
  • Zero RPM fan mode stops the fan at low loads for near-silent running
  • Resonant LLC topology with DC-to-DC conversion delivers clean, consistent power
  • Resonant LLC topology reduces coil whine for quieter operation

ATX Power Supply for Modern Standby Builds

This ATX power supply is built for desktop systems that use Modern Standby sleep states. It delivers fast wake-from-sleep response and strong low-load efficiency. The unit suits builders who want reliable power without extra noise at idle.

Sustained Load Behaviour with 80 PLUS Gold

Under continuous load the 80 PLUS Gold certification keeps efficiency high, which reduces waste heat and keeps internal temperatures lower. The resonant LLC topology with DC-to-DC conversion maintains clean, stable output and limits coil whine. The fan remains off at low and medium loads through the Zero RPM mode, so acoustic output stays minimal even during long sessions.

12 and 24 Pin ATX Connectivity

The product name references 12 and 24 pin ATX connectors, which determines motherboard compatibility. Systems needing a different main-power pin count or a proprietary connector cannot use this unit. Builders should verify their board’s power-header layout before purchasing.

Questions about this item

How quiet is the GFR1K5PS power supply when my system runs all day?

The Zero RPM Fan Mode stops the fan completely at low and medium loads, while the resonant LLC topology with DC-to-DC conversion reduces coil whine for quieter operation.

What connectors must my motherboard already have for this ATX unit to work?

A standard 24-pin ATX motherboard connector and an 8-pin or 4+4-pin CPU power connector are required for the GFR1K5PS to function.

Will the GFR1K5PS support Modern Standby sleep states on my older motherboard?

Modern Standby compatibility requires motherboard and BIOS support; the GFR1K5PS enables efficient low-power states but cannot add the feature to hardware that lacks it.
