ATX 350 W power supply

The KHACHIMO VAT-H350-12-ST-DII is an ATX power supply rated at 350 W with a single 12 V rail delivering 29 A. It carries 80 PLUS Gold certification and uses a resonant LLC topology with DC-to-DC conversion to provide clean, consistent power while enabling efficient sleep states.

Systems needing quiet, efficient 350 W ATX power

This unit suits builds that value low-noise operation and Modern Standby support, thanks to a Zero RPM fan mode that stops the fan at low and medium loads. Builds requiring higher wattage, multiple 12 V rails, or non-ATX form factors should consider other options.

Single 12 V rail rated at 29 A

The 12 V rail supplies up to 29 A, which determines whether the unit can power the installed components. Verify that the total 12 V current draw of your hardware stays within this limit before purchasing.

Perguntas sobre este artigo

What motherboard power connector does the KHACHIMO VAT-H350-12-ST-DII 350W ATX power supply require?

It uses a standard ATX 24-pin main connector plus a 4+4-pin CPU power connector, so the motherboard must provide both sockets.

Will the 80 PLUS Gold efficiency and Modern Standby support work with an older motherboard that only supports legacy S3 sleep?

Yes, the unit delivers 80 PLUS Gold efficiency at all loads and remains fully compatible with legacy S3 sleep; Modern Standby features simply remain inactive on older platforms.

How can I confirm the Zero RPM fan mode is active after installation?

Under light system load the fan will stop spinning completely; you can verify this visually or by listening for the absence of fan noise while the PC is idle.
