500 W ATX Power Supply for Modern Standby Systems

This 500 W ATX unit carries 80 PLUS Gold certification and is built for Modern Standby compatible platforms. It suits builders who want efficient, low-noise power in a compact 1U form factor. The resonant LLC topology with DC-to-DC conversion delivers clean output for stable operation.

Modular Cabling Simplifies Installation in Tight

Fully modular cables let you connect only what the build needs, which is critical in 1U chassis where routing space is limited. The Zero RPM fan mode stays off at low and medium loads, so there is no fan noise during typical desktop use. Ensure the 1U height matches your case or rack specification before fitting.

Verify 1U Clearance and Connector Requirements First

Check that your case or rack accepts a 1U high power supply and that the modular connector layout matches your motherboard and GPU power needs. The Modern Standby feature requires a compatible motherboard and operating system to function. Buyers needing higher wattage or a standard ATX height unit should consider other models.

商品問答

How do I confirm the power supply is operating correctly once installed?

Check that the system powers on reliably, the fan remains off during light loads due to Zero RPM mode, and Modern Standby wake times are near-instant.

What components come in the package and what must I source separately?

The box contains the 500W modular PSU and its detachable cable set; mounting screws and a power cord are typically included, but verify your case and motherboard needs.

Which capacity from the M99 line should I pick for a mid-range build?

The 500W Gold model suits mainstream CPUs and single GPUs; choose it when your estimated peak draw stays comfortably below 500 watts.
