Seasonic FOCUS GX-1000 V4 PSU ATX 3.1 1000W Gold

Seasonic FOCUS GX-1000 V4 is a 1000W modular power supply of high quality, aimed at serious gaming and workstation configurations. You have an 80+ Gold certification and claimed efficiency of up to 90%, which means less loss and lower temperature compared to cheaper PSUs. The power supply is compliant with the ATX 3.0/3.1 standard with support for PCIe Gen 5.0/5.1, so you are ready for modern high-end GPUs. The format is standard ATX in black color, without RGB, for a cleaner build.

What you get

With a power of 1000W and active PFC, you have a stable power supply for systems with powerful CPUs + high-end GPUs, even under peak loads. The PCI-E Gen5 12VHPWR connector allows you to directly power modern graphics cards without the need for adapters, while the three PCI-Express 6+2 pin connectors provide flexibility for previous generation GPUs. The eight SATA and three Molex connectors easily cover many SSDs, HDDs, and additional devices like fans and controllers. The modular design allows you to connect only the necessary cables, which simplifies cable management and improves airflow. The large 135mm FDB fan helps for quieter and more reliable operation, especially under heavy load.

• Power 1000W – sufficient for configurations with high-end GPUs and powerful multi-core CPUs, even during overclocking and long gaming sessions.
• 80+ Gold certification and up to 90% efficiency – less loss in heat and lower load on the electrical network at the same performance.
• ATX 3.0/3.1 with PCIe Gen 5.0/5.1 support – readiness for current and future graphics cards according to the new standards.
• PCI-E Gen5 12VHPWR + 3x PCI-Express 6+2 pin – full flexibility for connecting modern and older GPUs without compromises.
• 8x SATA and 3x Molex connectors – comfortable powering of many SSD/HDD devices, peripherals, and additional accessories in the case.
• Modular power supply unit – easier installation, fewer excess cables, and better internal airflow.
• 135mm FDB fan – quieter operation and longer life thanks to more reliable bearing.

Who is this suitable for

This PSU is a good choice if you are planning a serious gaming or creative workstation build with a powerful graphics card, plenty of storage, and long periods under load. It is especially sensible if you want to switch to a GPU with a 12VHPWR connector and be assured of the ATX 3.0/3.1 standard. If you are making a small budget build with low consumption, this power is rather overkill.

The most sensible aspect of this model is the combination of 1000W power, 80+ Gold efficiency, and full ATX 3.1 / PCIe Gen5 support, plus a modular design that makes both the current build and future upgrades much easier.
