Product Information

Full details

The Seasonic FOCUS GX-1000 is a high-performance 1000W power supply unit designed for PC builders and enthusiasts seeking reliable, efficient power for demanding systems. Its key benefit lies in its ATX 3.1 and PCIe 5.1 compliance, ensuring compatibility with the latest high-power graphics cards and processors, alongside advanced cooling and noise reduction technologies. A potential caveat for some users might be its compact 140mm depth, which, while versatile, may require specific case considerations.

Extended Product Information

FAQs

What is ATX 3.1 and PCIe 5.1 compliance?

ATX 3.1 and PCIe 5.1 are the latest standards for power delivery and connectivity, designed to support the increased power demands and transient spikes of next-generation computer hardware, particularly high-performance graphics cards.

What is the benefit of Digital Hybrid Fan Control?

This patented technology allows the fan to operate in three stages: Fanless Mode (silent operation at low loads), Silent Mode (quiet operation with minimal fan speed), and Cooling Mode (active cooling under high loads). This optimizes for noise reduction, fan lifespan, and efficient heat dissipation.

What does 80 PLUS Gold certification mean?

It signifies high energy efficiency, meaning the PSU wastes less power as heat. 80 PLUS Gold certification guarantees at least 87-90% efficiency at typical loads (20%, 50%, 100%), leading to lower electricity bills and reduced thermal output.

Is the cabling fully-modular?

Yes, the FOCUS GX-1000 features a fully-modular design, allowing you to connect only the cables you need for your specific build, which improves cable management and airflow.

What is the warranty period for this PSU?

The Seasonic FOCUS GX-1000 comes with a 10-year warranty, reflecting its build quality and reliability.

How does the OptiSink Design improve performance?

The OptiSink Design uses a redesigned PCB layout with smaller MOSFETs and heatsinks, increasing internal space for better airflow and heat dissipation. This results in cooler internal component temperatures, enhancing reliability and efficiency.

What type of fan bearing does it use?

It utilizes a high-performance Fluid Dynamic Bearing (FDB) fan, known for its quiet operation, reduced vibration, and significantly longer lifespan compared to traditional ball bearings.

Troubleshooting

Power supply unit does not turn on.

Ensure the AC power cord is securely connected to both the PSU and a working wall outlet. Check that the PSU's on/off switch is in the 'I' (on) position. Verify that all modular cables are firmly seated in their respective ports on the PSU and motherboard.

System is unstable or crashing under load.

Confirm that all power cables, especially the CPU and GPU power connectors, are properly seated. Ensure the PSU's wattage is sufficient for all components. Check for any signs of overheating and ensure proper case airflow.

Fan is making unusual noise.

The fan uses Fluid Dynamic Bearings, which are generally quiet. If you hear clicking or grinding, it might indicate a foreign object or bearing issue. Ensure the fan is not obstructed. If noise persists, contact Seasonic support.

No power to specific components (e.g., GPU, SSD).

Verify that the correct modular cables are used for the specific component (e.g., PCIe cable for GPU, SATA cable for SSD). Try using a different cable of the same type if available, as the issue might be with the cable itself.

Pros and Cons

Pros

  • Excellent power delivery for high-end systems.
  • Future-proofed with ATX 3.1 and PCIe 5.1 support.
  • Quiet operation due to Digital Hybrid Fan Control and FDB fan.
  • High energy efficiency with 80 PLUS Gold certification.
  • Reliable build quality with improved thermal management.
  • Fully-modular design simplifies cable management.

Cons

  • Premium pricing may be a factor for budget-conscious builders.
  • The 140mm depth, while versatile, might be restrictive in very small form factor cases.
  • Requires careful consideration of cable routing for optimal airflow within the compact chassis.

Setup, Compatibility & Care

Setup:

  1. Ensure your PC case has adequate space for a 140mm deep power supply unit.
  2. Install the power supply into the designated bay in your PC case.
  3. Connect the necessary modular cables to the PSU: 20+4 pin ATX for the motherboard, CPU power connectors (4+4 pin EPS), PCIe power connectors (including the 12V-2x6 for compatible GPUs), and SATA/Molex connectors for drives and peripherals.
  4. Connect the other ends of the cables to your motherboard, GPU, and storage devices.
  5. Plug the AC power cord into the PSU and a wall outlet.

Compatibility:

  • Form Factor: ATX
  • Motherboard: Compatible with standard ATX, micro-ATX, and mini-ITX motherboards (ensure case compatibility).
  • CPU Power: Supports ATX12V standards with 4+4 pin EPS connectors.
  • GPU Power: Compatible with PCIe 5.0 and 6+2 pin connectors, including the new 12V-2x6 standard.
  • Storage and Peripherals: Supports SATA and Molex devices.

Care:

  • Periodically clean the dust filter on the PSU intake (if your case has one) to ensure optimal airflow.
  • Avoid covering the PSU fan or ventilation openings.
  • Keep the area around the PSU free from obstructions.
  • Use compressed air to gently blow dust out of the PSU fan and heatsinks if accessible and safe to do so. Ensure the PSU is unplugged before performing any cleaning.
