  • Chassis styleDesktop
  • 800 W continuous power for 24/7 server loads
  • 80 PLUS Titanium efficiency cuts energy waste
  • All Japanese capacitors ensure long-term reliability
  • 100 % modular flat cables simplify compact builds
  • 120 mm fan with semi-fanless mode keeps noise low

SFX-L Titanium 800W server power supply

This SFX-L form factor unit delivers 800W of continuous power rated for 24/7 operation. It targets builders of small form factor systems who need class-leading output density. The 100% modular design uses flexible flat cable arrays for clean routing in tight desktop chassis. All Japanese capacitors underpin the high-quality construction.

80 Plus Titanium sustained load behaviour

The power supply maintains strict 3% voltage regulation with low ripple and noise under continuous demand. A single +12V rail provides 66A for stable delivery to demanding components. Advanced semi-fanless operation keeps the 120mm fan silent during lighter loads while ensuring cooling under sustained stress. Efficiency meets the highest 80 Plus Titanium standard across the operating range.

SFX-L form factor practical limits

The larger 120mm fan introduced with the SFX-L standard in 2015 balances power and quietness better than standard SFX allows. This design supports quad PCI-E 8/6pin connectors for multi-GPU configurations within the compact footprint. Builders needing more connectors or higher wattage than 800W must look beyond the SFX-L envelope. The short modular cables suit small cases but limit reach in larger enclosures.

Questions about this item

How quiet is the 120mm fan when the 800W unit runs 24/7?

The 120mm fan uses advanced semi-fanless operation, staying silent at low loads and spinning only when needed for continuous 24/7 rated output.

Which power connectors must my graphics cards already have for the modular cables?

The supply includes quad PCI-E 8/6pin connectors on fully modular flat cables, so each GPU needs matching 8-pin or 6-pin inputs.

Will the single +12V rail with 66a work with older components that expect multi-rail limits?

The class-leading single +12V rail delivers 66a without per-rail caps, so legacy parts draw what they need without tripping over-current protection.
