ASRock Challenger Power Supply 750W ATX - Efficient Bronze PSU

In this review the ASRock Challenger Power Supply 750W is evaluated for midrange desktop builders who need a reliable, cost-conscious unit that supports newer GPUs. The bottom line: this PSU is best for systems under 900W where reliable delivery, a quiet fan and solid cable quality matter more than fully modular convenience. It stands out for its 80 PLUS Bronze efficiency, native PCIe5.1 readiness and a large 120mm golf-blade fan that keeps noise low while meeting modern connector requirements.

Key Features

• 80 PLUS Bronze Certified: Delivers improved efficiency under typical loads, helping reduce wasted energy compared with non-certified units.
• PCIe5.1 Ready: Includes modern GPU power support so recent graphics cards can be connected without adapter workarounds.
• 120mm Golf-blade Fan: A larger, quiet fan profile reduces audible noise during normal desktop use while maintaining airflow for stable voltages.
• Native 12V-2x6 Connector: Provides direct support for two 6-pin 12V connections which simplifies cabling for compatible devices.
• Built-in 5V BOOST function: Offers extra 5V rail stability for boards and accessories that can benefit from a temporary boost under load.
• Compact ATX footprint: The 5.1 x 5.91 x 3.39 in dimension fits most mid-tower cases without obstructing drive cages.

Who It's For

This unit is aimed at PC builders assembling gaming rigs or workstations that draw less than about 900W peak and who value quiet operation, solid cabling and modern connector support. It is especially suitable for budget-conscious users who want PCIe5.1 compatibility without paying for fully modular or flagship models.

Users who prioritize a fully modular layout, extreme overclocking headroom, or ultra-high efficiency (Gold or better) should look elsewhere. Also note this supply is not compatible with all built-in computers or proprietary OEM cases that require custom power shapes or connectors.

Pros & Cons

Pros

• Quiet 120mm golf-blade fan keeps acoustics low during light and moderate loads.
