Power supply Asrock CL-750G Challenger 750W 80 Plus Gold ATX 3.1, PCIe 5.1 PSU

Asrock CL-750G Challenger is a 750W ATX power supply, aimed at mid-range to more serious gaming and work configurations, where you want stability and good efficiency without unnecessary extras. It relies on an 80+ Gold certification and up to 90% efficiency, which means less energy loss and lower temperature in the case. It supports ATX 3.0/3.1 and PCIe Gen 5.0/5.1, so you are covered for modern GPUs with the new connector standard. There is no RGB and modularity, the focus here is on functional design and reliability.

What you get

With 750W power, you have enough resources for a strong GPU, modern CPU, and several additional devices, without worrying about shortages under load. The PCIe5.1 connector (12+4pin) provides direct compatibility with the new generation of graphics cards, without the need for adapters, while the additional PCIe (6+2pin) offers options for older or second GPUs. The four SATA and two 4-pin peripheral connectors are more than enough for SSDs, HDDs, and peripherals in a standard gaming or work build. Active PFC helps for more stable power supply and better power factor, while the protections OCP, SCP, OVP, UVP, OTP, OPP keep your components safe in case of network issues or overload. The 120mm fan covers the cooling of the compact chassis with a length of only 140 mm, which makes installation in smaller cases easier.

• Power 750W – sufficient for a strong gaming or work configuration with modern GPU and plenty of storage.
• 80+ Gold certification and up to 90% efficiency – less loss as heat, lower consumption, and quieter fan under typical load.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 support – ready for new graphics cards and the consumption peaks anticipated in the current standard.
• 1x PCIe5.1 (12+4pin) and 2x PCIe (6+2pin) – flexibility for modern and older GPUs, without compromising their power supply.
• 2x EPS 12V (4+4pin) – stable power supply for modern motherboards and smoother current delivery to the CPU under serious load.
• 4x SATA and 2x 4-pin Peripheral connectors – enough connections for SSDs, HDDs, fans, and additional peripherals in a typical build.
• Active PFC and a full package of protections (OCP, SCP, OVP, UVP, OTP, OPP) – better electrical stability and protection of components against anomalies.
• Compact dimensions 140 x 150 x 86 mm and 120mm fan – easy installation in most ATX cases and adequate cooling without excessive noise.
• 60 months warranty – long-term coverage that complements the idea of a reliable choice.

Who it is suitable for

It is suitable if you aim for a stable mid-range or upper mid-range gaming/work computer with modern GPU and want ATX 3.1 and PCIe 5.x compatibility. If you prioritize modular cable management and a minimal number of unnecessary cables, this is not the best choice, but if power, standard, and reliability against a reasonable budget are your priorities – it fits perfectly.

The combination of 750W, 80+ Gold efficiency, and support for ATX 3.1 / PCIe 5.1 makes Asrock CL-750G Challenger a very sensible option for current and future builds, without unnecessary embellishments, but with the necessary standards and protections.
