Power delivery for mid-range builds

This 650 W ATX unit targets systems that need reliable output without excess headroom. It suits gaming rigs, workstations and general-purpose PCs where a single high-end graphics card and modern CPU form the core. The white finish matches light-themed chassis while the fully modular design keeps cable clutter to a minimum.

Fully modular cabling and wide input

Every cable detaches so only the required leads occupy the case, simplifying routing and airflow. The package includes four 6+2-pin PCIe connectors, eight SATA power plugs and four CPU 4-pin leads to cover typical component counts. Active PFC accepts 100-240 V at 50/60 Hz, allowing the same unit to operate worldwide without a voltage switch.

Sustained output with quiet thermal control

A 140 mm hydraulic fan runs under automatic speed control and can stop entirely at low load, reducing noise during idle or light tasks. Japanese 105 °C electrolytic and solid capacitors feed an LLC resonant topology that maintains >90 % efficiency under continuous demand. Full protection suites OVP, OCP, UVP, SCP, OTP and OPP guard components during prolonged heavy use.

Questions about this item

How much continuous power can the 650 W unit actually deliver on the +12 V rail before protection triggers?

The +12 V rail is rated for the full 650 W, and OCP will engage only if that limit is exceeded.

What noise and heat should I expect from the 140 mm hydraulic fan during all-day loads?

The 14025 hydraulic fan runs under automatic speed control and stops completely at low load, keeping noise minimal.

Which cables must I already have to connect this fully modular PSU to my components?

No cables are pre-attached; the box includes the modular cable pack with 4 CPU 12 V, 4 SATA, and 4 PCIe 6+2-pin leads.
