Seasonic FOCUS GX-750 V4 PSU ATX 3.1 750W Gold

Seasonic FOCUS GX-750 V4 is a 750W, fully modular ATX power supply from the higher mid-range, aimed at serious gaming and workstation configurations. It combines 80+ Gold certification with up to 90% efficiency, which means less heating and less load on the fan during normal operation. Support for ATX 3.0/3.1 and PCIe Gen 5.0/5.1 prepares you for modern and future GPUs. The included PCI-E Gen5 12VHPWR connector is a direct plus if you are considering newer graphics cards without adapters.

What you get: 750W real power is sufficient for a modern configuration with a strong CPU and mid to high-end GPU, without worrying about stability under load. Active PFC helps provide cleaner and more stable power to components, especially under fluctuating network voltage (100–240 VAC). The large 135mm FDB fan is designed for quieter operation and long life, as fluid dynamic bearing bearings last longer than standard sleeve/bearing solutions. The fully modular design gives you the freedom to use only the necessary cables, making cable management easier and improving airflow in the case. The rich set of connectors – from classic Molex to 12VHPWR – allows you to connect modern GPUs, multiple drives, and additional devices without the need for adapters.

• Power 750W – sufficient for a strong gaming or creative build with a powerful GPU and multi-core CPU, without being on the edge of the power supply's capabilities.
• 80+ Gold certification and up to 90% efficiency – less loss as heat, lower consumption from the outlet, and quieter operation during long gaming sessions.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support – fully current standard for new platforms and graphics cards, with better resilience to momentary peak loads.
• PCI-E Gen5 12VHPWR connector – direct power for modern GPUs without additional adapters and cable chaos.
• Fully modular design – you connect only the necessary cables, making assembly cleaner and improving airflow in the case.
• 135mm FDB fan – quieter and more durable fan with fluid dynamic bearing for long-term stability and lower noise.
• Rich set of connectors – 20+4 Pin ATX, two 4+4 Pin ATX/EPS, PCI-Express 6+2 pin x2, SATA (including SATA 3.3 V) and Molex cover most combinations of drives, fans, and peripherals.

Who it is suitable for: It is suitable if you are building a serious gaming PC, streaming/creative build, or upgrading to a new generation GPU and want ATX 3.1 and 12VHPWR out of the box. It is also a good option if you care about a quieter and more efficient system with fewer unnecessary cables. It is not the optimal choice if you are making a completely budget office computer or an ultra-low-consumption build, where 750W will simply be excessive.

The combination of 750W power, 80+ Gold efficiency, and full support for ATX 3.1 with 12VHPWR makes this Seasonic solution a very balanced foundation for a modern and future build. If you are looking for stability, current standards, and a clean assembly, the FOCUS GX-750 V4 gives you just that.
