Power Supply Seasonic FOCUS GX-750 White 750W 80 Plus Gold ATX 3.1 PCIe 5.1 Fully Modular PSU

Seasonic FOCUS GX-750 White is a high-end ATX power supply aimed at serious gaming and workstation configurations with modern graphics cards. Despite the "750" in the name, its actual rated power in the catalog is 850W, giving you a serious reserve for a powerful CPU and strong GPU. The 80+ Gold certification and declared 90% efficiency help reduce consumption and excess heat. The white color makes it a suitable accent for clean, light builds without relying on RGB effects.

What you get

With ATX 3.0/3.1 and PCIe Gen 5.0/5.1 support and a 12VHPWR (12+4) Pin connector, you are fully prepared for modern and future high-end GPU models without using adapters. The three PCI-Express 6+2-pin connectors give you flexibility for older or mid-range graphics cards, multi-GPU for specific tasks, or additional cards (capture, RAID, etc.). With 8 SATA and 3 Molex connectors, you can easily power several SSDs/HDDs, fans, and peripherals in a more loaded case or NAS-type system. The two CPU 4+4 Pin connectors are a plus if you plan to use a more serious motherboard and multi-core processor. The 135mm FDB fan with fluid dynamic bearing ensures quieter and longer-lasting operation compared to basic sleeve solutions, especially under higher loads.

• Real power 850W provides a stable reserve for a powerful gaming or workstation build with high-end CPU and GPU.
• 80+ Gold certification with around 90% efficiency means less loss as heat and lower electricity bills during long gaming sessions or 24/7 loads.
• ATX 3.0/3.1 and PCIe Gen 5.0/5.1 compatibility ensure that the power supply is ready for the demands and peaks of the new generations of graphics cards.
• 1 x 12VHPWR (12+4) Pin connector allows you to directly connect a modern high-end GPU without additional adapters and unnecessary converters.
• 3 x PCI-Express 6+2-pin, 8 x SATA and 3 x Molex provide enough connections for graphics cards, drives, fans, and accessories in a more complex build.
• 2 x CPU 4+4 Pin give freedom for more serious motherboards and processors with higher power requirements.
• 135mm FDB fan combines lower noise and longer life, which is important if you are looking for a quiet machine under constant load.
• Fully modular design and white color help with clean cable management and an aesthetic white build without unnecessary cables.

Who it is suitable for

This power supply is suitable if you are planning a serious gaming or creator PC with a powerful graphics card from the current generations and want ATX 3.x compatibility and a clean build with modular cables. It is excellent for mid- to high-end 1440p/4K configurations, where stability under load is critical. If you are aiming for a super budget machine or a small SFF build, this solution will likely be more than you need in terms of power and size.

The most sensible aspect here is the combination of 850W power, 80+ Gold efficiency, and ATX 3.0/3.1 with 12VHPWR, in a fully modular, white case — practical, current, and ready for a serious upgrade cycle ahead.
