1700W ATX power supply for high-end builds

The KHACHIMO ZXD1500V3.0 delivers 1700W of continuous power through an ATX form factor. It targets enthusiasts and workstation builders who need substantial headroom for multi-GPU configurations or extreme overclocking. Modern Standby compatibility ensures extremely fast wake-from-sleep times and improved low-load efficiency. The unit is not suited for compact chassis that cannot accommodate standard ATX dimensions.

80 PLUS Gold efficiency with Zero RPM fan mode

80 PLUS Gold certification guarantees high efficiency operation for lower power consumption, less noise, and cooler temperatures during typical workloads. Zero RPM fan mode keeps the cooling fan completely stopped at low and medium loads for near-silent operation. Resonant LLC topology with DC-to-DC conversion provides clean, consistent power while reducing coil whine and enabling more energy efficient sleep states.

Sustained load stability through resonant LLC

Under sustained heavy loads the resonant LLC topology with DC-to-DC conversion maintains clean, consistent power delivery without the voltage drift seen in simpler designs. The gold-rated efficiency curve keeps thermals controlled during extended rendering or compute sessions. Coil whine remains suppressed even when the fan spins up, and Modern Standby support allows rapid return to full output after sleep states. Builders needing redundant power phases for mission-critical uptime should evaluate server-grade alternatives.

Questions about this item

How do I install the KHACHIMO ZXD1500V3.0 1700W ATX power supply and which step is often missed?

Mount the unit in a standard ATX case using the four rear screws, connect the 24-pin motherboard and CPU power cables, then route all modular cables before tightening everything; the step most people forget is plugging in the PCIe power connectors for the graphics card.

What maintenance or replacement will the ZXD1500V3.0 need later?

The 80 PLUS Gold unit uses a Zero RPM fan that stops at low load; over years the fan bearing may wear, so plan to clean dust from the intake grille annually and replace the fan if noise appears.

What limit appears first on the 1700W supply under sustained heavy load?

Continuous output is rated at 1500W; pushing beyond that triggers over-power protection and shuts the unit down, so the practical ceiling is the 1500W sustained figure.
