SKU CH-XYYX-CN3D2

An 800 W SFX-L power adapter with 80 Plus Titanium efficiency, a 120 mm fan and Japanese capacitors for compact high-performance builds

  • 800 W output powers demanding small-form-factor builds
  • 80 Plus Titanium rating delivers highest certified efficiency
  • SFX-L design with 120 mm fan balances cooling and quiet operation
  • Fully modular flat cables simplify routing in tight cases
  • All Japanese capacitors ensure long-term reliability

800W SFX-L power supply for compact builds

This 800 watt SFX-L unit targets enthusiasts building high-performance small form factor PCs. The larger 120 millimetre fan allows a balance of power delivery and low noise that standard SFX units cannot match. It suits systems where space is limited but output and efficiency must remain high.

80 Plus Titanium efficiency and semi-fanless

At typical loads the power supply meets the highest 80 PLUS Titanium efficiency level, reducing waste heat and keeping the fan idle during light use. All Japanese capacitors and flexible flat cables support stable, cool running in tight enclosures. The advanced semi-fanless mode keeps acoustics minimal for everyday workloads.

Sustained 800W delivery without throttle

Under continuous heavy demand the unit maintains its full rated output rather than dropping to a lower sustained figure. The 120 millimetre fan spins up only as needed, preserving airflow while avoiding the sudden ramp-ups common in smaller designs. Builders who need uninterrupted peak power in a compact chassis will find the thermal headroom adequate.

Questions about this item

How do I install the SX800-LTI in an SFX-L case and what step is often missed?

Mount the 120 mm fan unit into the SFX-L bay, connect the modular flat cables only to the ports your build needs, and remember to set the semi-fanless switch before first power-on — many builders forget that step.

What maintenance or replacement will the SX800-LTI need later?

The 120 mm fan bearings are the only moving part; plan to clean dust from the fan grill annually and replace the fan if noise or vibration appears after several years.

What limit appears first under sustained load on the SX800-LTI?

Continuous 800 W output at 80 Plus Titanium efficiency is the ceiling; beyond that the protection circuits shut the unit down to protect the Japanese capacitors.
