350W ATX power supply for efficient builds

The KHACHIMO EMH350PS12 delivers 350 watts of continuous power in a standard ATX form factor. Its 80 PLUS Gold certification ensures high efficiency across typical loads, reducing electricity draw and heat output. Modern Standby compatibility allows extremely fast wake-from-sleep times and improved low-load efficiency. This unit suits office PCs, compact workstations or entry-level gaming rigs where quiet, efficient operation is a priority.

Check ATX clearance and 12V rail demand before

Verify that your case accepts a standard ATX power supply and that the motherboard uses a 24-pin ATX connector plus the required 12V CPU power connector. Ensure the combined 12V load of your components stays within the unit’s rated capacity, as the single 12V rail must handle graphics card, processor and drive power simultaneously. Confirm cable reach matches your component layout, especially in larger or unusually routed enclosures.

Gold-rated efficiency

The 80 PLUS Gold rating means less waste heat, so the cooling fan can remain off at low and medium loads thanks to Zero RPM mode, providing near-silent operation during everyday tasks. Resonant LLC topology with DC-to-DC conversion delivers clean, consistent voltage regulation and reduces coil whine, contributing to quieter performance and support for deeper sleep states. These design choices suit noise-sensitive environments and systems that spend long periods idle.

Questions sur cet article

Does the EMH350PS12 come with all cables or do I need to buy any separately?

The unit ships with the standard ATX cable set required for a typical build; no extra cables are needed for normal installation.

Should I choose the 350 W model or a higher-wattage version for a system with a mid-range GPU?

At 350 W this supply suits office PCs and entry-level graphics cards; a mid-range GPU usually demands more headroom so a higher-wattage unit is safer.

What does the 80 PLUS Gold rating mean for daily power draw and heat?

It guarantees at least 80 % efficiency at typical loads, so the PSU wastes less electricity, runs cooler and keeps fan noise lower.
