550W ATX Gold Power Supply
The KHACHIMO L550E-S1 is a 550W ATX power supply built for modern desktop systems that demand efficient and stable power delivery. It carries 80 PLUS Gold certification and supports Modern Standby for rapid wake-from-sleep performance.
Resonant LLC Topology with DC-to-DC Conversion
This topology provides clean, consistent power while reducing coil whine for quieter operation and enabling more energy-efficient sleep states. The Zero RPM fan mode stops the cooling fan entirely at low and medium loads for near-silent running.
Upgrade from lower-efficiency or noisy units
The jump is worth it when replacing a supply that lacks Gold-rated efficiency, Modern Standby support, or a semi-passive fan mode. It is not for builds requiring higher wattage than 550W or server-grade redundancy features.

商品問答
Does this 550W ATX power supply support Modern Standby for fast wake-from-sleep?
Yes, it is Modern Standby compatible, giving extremely fast wake-from-sleep times and better low-load efficiency.
Will this unit fit a standard ATX case and what mounting pattern does it use?
It follows the ATX form factor, so it mounts in any standard ATX chassis using the usual four-screw pattern on the rear panel.
How do I enable the Zero RPM fan mode and what load range keeps the fan off?
The fan stops automatically at low and medium loads; no software or BIOS setting is needed — just ensure the PSU fan can draw cool air.
