KHACHIMO 500W ATX Power Supply HP2-6500P-R 80 PLUS Gold

500W ATX Gold power supply for modern PCs

The KHACHIMO HP2-6500P-R delivers 500 watts of continuous power through a standard ATX form factor. It carries 80 PLUS Gold certification for high efficiency across typical loads. Modern Standby compatibility allows extremely fast wake-from-sleep transitions and improved low-load efficiency. This unit suits builders assembling new systems or replacing older supplies in compatible chassis.

Sustained load behaviour with LLC resonant topology

A resonant LLC topology combined with DC-to-DC conversion maintains clean, consistent voltage regulation during extended work sessions. The design reduces coil whine and supports deeper, more energy-efficient sleep states without voltage drift. Zero RPM fan mode keeps the cooling fan off at low and medium loads, eliminating acoustic noise while thermal headroom remains. Under heavier sustained demand the fan engages automatically to maintain safe component temperatures.

Build quality and connector implications day to day

Gold-rated efficiency lowers waste heat, which reduces internal stress on capacitors and extends operational lifespan. The fully compliant ATX layout fits standard mounting points and cable routing channels in most cases. Modern Standby support means the supply works correctly with current motherboard power-management features, avoiding wake failures or sleep-state instability. No proprietary connectors are used, so cable management follows familiar patterns.
