Questions about this item

What motherboard power connector does the ATX-type KHACHIMO AT P8P9 350W require?

This unit uses the standard ATX 24-pin main connector plus the usual 4-pin or 8-pin CPU power cable, so any modern ATX motherboard will plug in directly.

Can the 350W output replace my older 250W or 300W unit such as the SPI-250G or ST-300WHT?

Yes, the 350W rating provides more headroom than 250W or 300W models while keeping the same ATX form factor, making it a direct physical and electrical replacement.

How do I confirm the Zero RPM Fan Mode is active after installation?

Under light loads the fan will stop spinning completely; you can verify silent operation by listening for no fan noise while the system idles or runs low-power tasks.
