Overview

The Seasonic Focus GX-750 White ATX3 is a 750W fully modular power supply that carries 80PLUS GOLD certification and a distinctive white finish. It is designed to power mid-to-high end gaming PCs and creative workstations with stable, efficient delivery. The unit features a 135mm fluid dynamic bearing fan with hybrid silent fan control, which stops the fan entirely at low loads for silent operation. It fully supports the ATX 3.0 standard and includes a dedicated 12V-2x6 (12+4 pin) cable for the latest GeForce RTX 40 and RTX 50 series graphics cards, eliminating the need for adapters. Compact at just 140mm depth, it fits easily in most ATX cases, and the use of Japanese 105°C aluminum electrolytic capacitors ensures long-term reliability.

Compatibility Guide

The Focus GX-750 White ATX3 uses the standard ATX form factor and fits any case that accepts an ATX power supply. It provides the following connectors: one 24-pin ATX, one 4+4-pin EPS 12V, two 6+2-pin PCIe, one 12V-2x6 (12+4 pin), three SATA, and two Molex. This combination is ideal for systems with a single high-end GPU. The PSU is backward compatible with ATX 2.x motherboards; however, to fully leverage the 12V-2x6 cable, a GPU that natively supports that connector is required (most RTX 40 and 50 series). With 750W capacity, it comfortably handles a Core i7 or Ryzen 7 CPU paired with an RTX 4070-class GPU; for top-tier configurations (i9/R9 + RTX 4090), a higher wattage unit is recommended.

Product Info

Released in late 2024, the Seasonic Focus GX-750 White ATX3 sits in the mid-high segment of the PSU market. Its 80PLUS GOLD efficiency guarantees at least 87% efficiency at 115V AC load, and voltage regulation is within ±3%. The unit is backed by a 10-year warranty, reflecting Seasonic’s confidence in its build quality. In terms of market positioning, it competes directly with other premium Gold-rated fully modular 750W units such as the Corsair RM750x and be quiet! Straight Power 11, but stands out with its white aesthetics and native ATX 3.0 support. The street price is around ¥24,180 on Japan, offering solid value for a feature-rich PSU.

Best Use Cases

White-themed PC builds: The white casing and white cables make it an excellent choice for builders aiming for a clean, all‑white aesthetic. Gamers upgrading to RTX 40/50 series: The included 12V-2x6 cable provides a direct, tidy connection without dongles, and the 750W capacity is ample for mid-range to upper‑mid GPUs. * Quiet PC enthusiasts: With its hybrid fan control, the fan stays off under typical desktop loads or light gaming, making it nearly silent.

Things to Consider

The white finish is attractive but requires careful handling to avoid smudges or discoloration over time. 750W is insufficient for extreme high‑end builds (Core i9‑14900K + RTX 4090) where 1000W+ is recommended, so assess your system’s peak draw carefully. The PVC embossed cables are somewhat stiff, which may make routing in tight cases a bit challenging. Also, the unit includes only one 12V‑2x6 cable; it is not designed for multi‑GPU setups. Finally, the 10‑year warranty applies only when the unit is purchased from an authorized retailer, so confirm the seller before buying. ## Specifications | Item | Specification | |------|--------------| | Model | FOCUS GX-750 White ATX3 | | Rated Power | 750W | | Efficiency Certification | 80PLUS GOLD | | ATX Version | ATX 3.0 | | PCIe Connector | 12V-2x6 (12+4 pin) ready | | Modular Type | Fully Modular | | Fan Size | 135mm | | Bearings | Fluid Dynamic Bearing | | Fan Control | Hybrid Silent Fan Control | | Depth | 140mm | | Capacitors | Japanese 105°C Aluminum Electrolytic | | Protections | OPP/OVP/UVP/SCP/OCP/OTP | | Warranty | 10 years | | Included Cables | 1×24-pin ATX, 1×EPS 4+4-pin, 2×PCIe 6+2-pin, 1×12V-2x6, 3×SATA, 2×Molex |
