ASRock Challenger 750W Power Supply ATX 3.1 - Efficient, Quiet

In this review the ASRock Challenger 750W is presented as a mid-range ATX 3.1 power supply aimed at builders who need reliable power for modern GPUs without paying enthusiast premiums. The bottom line: it delivers stable, efficient power with 80 PLUS Gold efficiency and a quiet fan profile, making it a strong choice for mainstream to high-end gaming rigs. The included intelligent fan control and a five year warranty are the single biggest reasons to consider it for a system where noise control and long-term reliability matter.

Key Features

• 80 PLUS Gold Efficiency: Up to about 90% efficiency under typical loads, which reduces wasted energy and heat in a desktop build.
• ATX 3.1 Compatibility: Designed for next-generation hardware and current standards to ensure stable power delivery for modern GPUs and CPUs.
• Auto iCOOL Intelligent Fan Control: Fan speed adjusts automatically to system load so the unit remains quiet during light use and ramps only when needed.
• 120mm Golf Blade Fan: A larger blade design helps move air effectively while keeping audible noise low in usual desktop scenarios.
• 5 Years Warranty: Multi-year coverage provides extra confidence for long-term builds and reduces worry about early failures.
• Compact Dimensions: The 140mm x 150mm x 86mm size fits most ATX cases without obstructing internal layout in typical mid-tower builds.

Who It's For

This unit is aimed at PC builders who want reliable, efficient power for a gaming or content-creation system without stepping up to pricier enthusiast supplies. It suits users pairing mainstream to high-end GPUs and modern CPUs who value a quiet fan and certified efficiency.

Those who should look elsewhere include extreme overclockers or systems requiring fully modular cable management for tight builds; this is a non-modular design and cables have received mixed feedback for stiffness, which may be awkward in very compact or display-oriented builds.

Pros & Cons

Pros

• Solid value for money with Gold efficiency and a five year warranty for long-term use.
• Quiet operation thanks to the intelligent fan control and 120mm golf blade design.
• Good broad compatibility for modern hardware and ATX 3.1 power needs.
• Compact footprint fits in most standard cases without issue.

Cons

• Cable quality is mixed; some users report stiff cabling that can be harder to route neatly.
• Being non-modular limits cable management options for very tidy or small builds.
