Power supply Akyga AK-U4-500 PSU 500W, 20+4 pin ATX, Black

AKYGA AK-U4-500 is a 500W ATX power supply from the Ultimate series, aimed at budget and mid-range configurations with a more powerful graphics card. It comes with 80 PLUS Bronze certification and efficiency over 80%, so it doesn't waste electricity and generates less heat. The ATX 12V V2.31 & EPS 12V V2.92 format makes it compatible with modern motherboards and CPUs. The black casing and standard length of 140 mm facilitate installation in most mid-tower cases.

What you get

With a real output power of 500 W and active PFC, this power supply is perfectly fine for current gaming and work configurations with a single GPU card, without extreme overclocking. The combination of 1x PCIe 6-pin and 1x PCIe 6+2-pin connectors allows you to power most mid-range GPUs with one or two connectors, without adapters. The six SATA connectors provide enough freedom for SSDs, HDDs, and optical devices, while Molex and mini-Molex cover older or niche peripherals. A 120 mm fan with automatic speed control ensures the power supply remains quiet at idle and ramps up only under heavier load. The built-in protection set (OVP, OCP, OPP, OTP, SCP, UVP) keeps your components safe from typical power supply issues or hardware faults.

• Nominal output power of 500 W, sufficient for modern configurations with one more powerful graphics card and several drives.
• 80 PLUS Bronze certification and efficiency over 80%, which means less energy loss and lower temperature.
• Format ATX 12V V2.31 & EPS 12V V2.92, compatible with current motherboards and CPU sockets in the desktop segment.
• A rich set of connectors: 1x 20+4-pin ATX, 1x EPS12V 4+4-pin, 1x PCIe 6-pin, 1x PCIe 6+2-pin, 6x SATA, 2x Molex, 1x mini-Molex for flexible cabling.
• Active PFC for more stable operation at input voltage 230 V AC, 50/60 Hz and better power quality to the components.
• 120 mm fan with automatic speed control, balancing between cooling and noise according to the load.
• Built-in protection set OVP, OCP, OPP, OTP, SCP, UVP, which protects your PC from overvoltage, overload, or short circuit.
• Long cables 45–75 cm for easier cable management in larger cases and included power cable for direct installation.

Who it is suitable for

AK-U4-500 is a sensible choice for budget and mid-range gaming builds, office machines, and all-round PC configurations where you have one more powerful graphics card, but are not chasing extreme high-end. It is suitable if you want a stable ATX power supply with all the necessary protections and PCIe connectors, without paying extra for modularity or RGB. If you plan on a top-end CPU plus flagship GPU with high consumption, it makes more sense to look for a higher wattage.

The most sensible aspect of this model is the combination of 500 W power, 80 PLUS Bronze efficiency, active PFC, and a full set of connectors, all packed into a compact ATX body with a 3-year warranty.
