SKU CH-KPGZ-E3FPX

A 750W fully modular ATX 3.0 power supply with 80 Plus Gold 91.8% efficiency, native 12VHPWR for 600W PCIe 5.0 graphics cards, and 200% total power excursion support

  • TypeATX 3.0 Compatible
  • Handles 200% total power excursion for stable ATX 3.0 operation
  • 8% typical-load efficiency cuts heat and extends component life
  • Fully modular cables reduce clutter and improve case airflow
  • Native 12VHPWR delivers up to 600W to PCIe 5.0 graphics cards
  • Includes 2x PCIe 4.0 plus 1x PCIe 5.0 connectors for RTX 4080/4070Ti support

750W ATX 3.0 PSU for PCIe 5.0 builds

This 750 watt power supply meets the ATX 3.0 and PCIe 5.0 specifications. It is built for systems that need a native 12VHPWR connection for modern graphics cards. The fully modular cable design lets you attach only the leads your build requires.

80 Plus Gold efficiency and thermal control

The unit carries 80 Plus Gold certification with a rated 91.8 percent efficiency at typical load. Lower waste heat reduces internal temperatures and helps components last longer. A 120mm fan handles airflow while the DC-DC and Full Bridge LLC topology keeps output stable during power excursions.

Native 12VHPWR plus PCIe 4.0 connectors

A single 12VHPWR cable delivers up to 600 watts to a PCIe 5.0 graphics card such as an RTX 4080 or 4070 Ti. Two additional PCIe 4.0 ports support RTX 20 or 30 series and AMD cards. The fully modular layout frees up case space by removing unused cables from the build.

Questions about this item

How do I install the native 12VHPWR cable for a PCIe 5.0 graphics card and what step is often missed?

Plug the native 12VHPWR cable directly into the PSU's PCIe 5.0 port and the graphics card, ensuring the connector seats fully until the latch clicks; the step often missed is confirming both ends are locked before powering on.

What maintenance or replacement will the 120mm silent fan need later?

The 120mm silent fan may require dust cleaning over time; if bearing noise appears, the fan assembly can be replaced, but no other user-serviceable parts are inside the fully modular unit.

What limit appears first under sustained load on the 750W unit?

The 750W continuous rating is the first limit; the PSU can handle 200% total power excursion and 300% GPU power excursion briefly, but sustained draw above 750W triggers protection.
