Designed for XP POWER X9-4W3P

This ATX power supply is built specifically for the XP POWER X9-4W3P platform. It delivers standard form-factor compatibility and modern standby support for fast wake-from-sleep transitions. The unit targets system builders and upgraders who need a direct replacement or new installation for that exact hardware. Its 80 PLUS Gold certification ensures high efficiency during typical workloads.

Suits quiet-focused builds not high-wattage needs

The zero RPM fan mode stops the fan completely at low and medium loads, making it ideal for noise-sensitive environments such as home offices or media PCs. Resonant LLC topology with DC-to-DC conversion reduces coil whine and provides clean power for stable sleep states. Builders requiring higher maximum output or modular cabling for custom loops should look at alternative units.

No bundled accessories change the install

The package contains only the power supply unit itself with fixed cables. There are no extra connectors, mounting brackets, software utilities or cable combs included. Installation relies on the standard ATX screw pattern and the cables already attached to the unit. Users must supply any additional adapters or cable-management accessories separately.

Questions about this item

What motherboard power connector does this ATX supply use?

It uses the standard 24-pin ATX main connector plus the required CPU and PCIe cables for a modern motherboard.

Will the Zero RPM fan mode stay silent when paired with an older GPU that idles at higher power?

The fan stops at low and medium loads, so an older GPU drawing more power at idle may keep the fan spinning.

How can I confirm the 80 PLUS Gold efficiency is active after installation?

Check that the system meets Modern Standby wake times and that the fan remains off during light desktop use.
