1stPlayer HA-1000BA4 1000W 80 Plus Gold ATX 3.1 PCIe 5.1 Full Modular PSU

1stPlayer HA-1000BA4 is a 1000W ATX power supply with 80+ Gold certification and ATX 3.1 / PCIe 5.1 support – aimed at serious gaming and high-end configurations with modern graphics cards. You get a fully modular design, so you can leave only the necessary cables in the case and maintain easy airflow. The power supply features active PFC and up to 90% efficiency, which means less loss and lower temperature. The black design without RGB makes it suitable for a clean, simple build without unnecessary lights.

What you get

With a power of 1000W and output lines DC 3.3/5/±12 V, this power supply easily handles a combination of a powerful CPU, high-end GPU, and multiple SSD/HDD devices. Thanks to the PCI-E Gen5 12VHPWR connector, you are ready for modern graphics cards without relying on adapters, and the three PCI-Express 6+2 pin connectors allow for older or additional GPU configurations. The eight SATA and four Molex connectors give you the option to connect enough storage, fans, and peripherals for a large case or workstation. 0 RPM Fan Mode keeps the 120mm fan off under low to moderate load, which means silence in idle, and under load, the cooling kicks in only when really needed. Japanese electrolytic capacitors and the declared MTBF 100,000 hours are a clear sign of focus on reliability and long life.

• Power 1000W – sufficient for high-end gaming configurations with a powerful GPU and many additional devices, without worrying about power shortages.
• 80+ Gold and up to 90% efficiency – less loss as heat and more stable voltages under heavy load.
• ATX 3.1 and PCIe 5.1 Ready – prepared for the new generation of graphics cards and hardware standards, so you don’t have to think about upgrading the PSU with the next GPU change.
• PCI-E Gen5 12VHPWR + 3× PCI-Express 6+2 pin – flexible connectivity for both modern and older graphics cards or additional GPUs.
• Fully Modular design – all cables are detachable, making cable management easier and improving airflow in the case.
• 120mm fan with 0 RPM Fan Mode – the fan stops under low to medium load for quieter operation during everyday tasks.
• Full Japanese electrolytic capacitors and MTBF 100,000 hours – oriented towards long-term stability and reliability for 24/7 use.
• Power supply 100–240 VAC and active PFC – stable operation over a wide input range and better power factor correction.

Who it is suitable for

This power supply is a good option if you are building a powerful gaming or creative build with a current or upcoming PCIe Gen 5 graphics card and want a power reserve. It is also suitable for a system with many drives, fans, and long gaming sessions or rendering loads. If you are aiming for an ultra-compact ITX build or a configuration with minimal consumption, 1000W may be more than you need.

The combination of 1000W, 80+ Gold efficiency, ATX 3.1 / PCIe 5.1 and fully modular design makes 1stPlayer HA-1000BA4 a sensible choice when you want both current standards, quiet operation, and long-term reliability.
