SKU CH-PY74-N4A39 MPN MPX-7503-AFAG-2BUV

Delivers 750 W through fully modular ATX 3.1 cabling with a 90° 12V-2x6 PCIe 5.1 connector, 80+ Gold efficiency, Japanese capacitors and a 120 mm HDB fan featuring zero-RPM mode

  • ColorBlack
  • TypeATX 12V Ver. 3.0
  • Maximum Power750 W
  • Fans1 x 120 mm HDB fan
  • PFCActive
  • Max PSU Length180 mm

Options 750W

  • ATX 3.1 support enables up to 450 W GPU power delivery
  • 80 PLUS Gold certified efficiency reaches 90 % at typical load
  • Fully modular cabling reduces clutter and improves case airflow
  • Zero-RPM fan mode keeps operation silent until temperature threshold
  • 100 % Japanese capacitors lower ripple noise and increase reliability

Designed for ATX 3.1 builds

This 750 W unit follows the ATX 3.1 specification and carries 80 PLUS Gold certification with Cybenetics Platinum efficiency. It targets system builders who need reliable power delivery for modern graphics cards and CPUs. Fully modular cabling keeps the interior tidy and airflow unobstructed.

90° 12V-2x6 cable improves GPU connection

The included 90-degree 12V-2x6 PCIe 5.1 connector routes cleanly in tight spaces and supports up to 450 W for the graphics card. Japanese capacitors reduce ripple noise and raise long-term reliability. A Zero-RPM fan mode stays off until temperatures demand active cooling.

Check case depth and GPU power needs

Verify that your chassis accommodates a 180 mm deep power supply before ordering. Confirm your graphics card uses the 12V-2x6 interface so the native cable fits without adapters. Ensure the mains supply falls within the 100–240 V, 50/60 Hz input range.

Questions about this item

When will the 120 mm HDB fan need replacement?

The fan uses a hydro-dynamic bearing rated for over 100000 hours MTBF, so replacement is unlikely during normal ownership.

What limits output during continuous 750 W operation?

The unit holds up power for at least 16 ms at full load and triggers over-temperature protection if internal heat exceeds safe thresholds.

How loud and hot does the PSU get when running all day?

Zero-RPM mode keeps the fan off until temperature rises; hexagonal fan cover and dedicated heatsink maintain 80 percent airflow intake for quiet thermal performance.
