SFX-L 1000W power supply

This SFX-L unit delivers 1000W of continuous power for small form factor computers. It carries Cybenetics Platinum certification and meets SFX12V 4.0 and PCIe 5.0 standards. A single +12V rail provides 83.3A for stable 24/7 operation.

Check case clearance and cable needs

Verify your chassis can accept a 130mm long SFX-L power supply. Confirm the motherboard requires a 24 pin ATX connector and whether the CPU needs one or two 8 pin EPS connectors. Ensure the graphics card uses a 12VHPWR or 8 pin PCIe connector.

Fully modular cables and semi-fanless cooling

All cables detach so you install only the 24 pin ATX, EPS, PCIe, 12VHPWR, SATA, peripheral and floppy leads required. The 120mm dual ball bearing fan runs silently and stops at low load. All Japanese capacitors support long term reliability.

Questions about this item

Will this SFX-L unit fit in a case that only accepts standard SFX supplies?

The SFX-L form factor is 130 mm long, which exceeds the 100 mm length of standard SFX. Check your case specifications for SFX-L clearance before ordering.

Can I power a modern graphics card that requires the 12VHPWR connector?

Yes. One native 12VHPWR (12+4) cable is included, compliant with the SFX12V 4.0 and PCIe 5.0 standards.

Is the fan always spinning or does it stop under light loads?

The 120 mm dual ball-bearing fan features a semi-fanless mode that stops the fan at low load and temperature for silent operation.
