KHACHIMO FSP 460W 80 PLUS Gold 1U Power Supply FSP460-701UG

SKU CH-39Y7-TFJ4B

460 W 80 PLUS Gold 1U ATX supply with zero-RPM fan mode and LLC resonant topology for silent, efficient server or workstation power

  • TypeATX
  • 80 PLUS Gold efficiency lowers running costs and heat
  • Zero RPM fan mode keeps the system near-silent at low loads
  • Resonant LLC topology with DC-to-DC conversion delivers clean power and cuts coil whine
  • Modern Standby compatible for ultra-fast wake and better sleep efficiency
  • Compact 1U ATX form factor fits space-constrained server and workstation chassis

Compact 1U Server Power Supply

The KHACHIMO FSP 460W unit is a new ATX-type power supply built for 1U rackmount chassis and other space-constrained enclosures. It targets system integrators and IT professionals who need reliable, efficient power delivery in a slim form factor without compromising on certified efficiency standards.

80 PLUS Gold Efficiency Rating

This supply carries 80 PLUS Gold certification, meaning it meets strict efficiency thresholds at typical loads to reduce waste heat and operating cost. The resonant LLC topology with DC-to-DC conversion further stabilises voltage regulation and supports modern low-power sleep states for compatible platforms.

Standard ATX Installation Profile

Installation follows the conventional ATX mounting pattern used in 1U server cases, so no special brackets or adapters are required. The zero-RPM fan mode eliminates noise at light loads, though installers should verify that the single 460W capacity matches the total system draw to avoid overload shutdowns.

Questions about this item

What does the 460 W rating mean when the unit is installed in a 1U server?

The 460 W rating is the maximum continuous power the supply can deliver to all rails combined inside a 1U chassis.

How does the ATX form factor limit cable routing in a 1U rack build?

ATX dimensions fix the unit at standard PSU height and depth, so cables exit at the rear and must be routed within the 1U vertical clearance.

What mounting points does the 1U design use to secure the supply in a rack cabinet?

The 1U housing uses the standard four-hole ATX/PS2 pattern on the rear flange, matching typical rack-mount trays and server bays.
