Power for high-end builds

The TROPRO RGB-550 delivers 850 W through a fully modular ATX12V design. It targets system builders who need reliable output for demanding graphics cards and CPUs. The single +12 V rail provides stable DC power across the entire platform. 80 PLUS Gold certification confirms high efficiency under typical loads.

850 W single-rail output

A single +12 V rail rated at 850 W is the specification that determines compatibility with high-end graphics cards. Two PCIe 6+2-pin connectors and one 8(4+4)-pin CPU connector supply the necessary power. The unit meets ATX12V 2.3 and 2.4 requirements for modern systems. Active power factor correction reaches 0.9 for cleaner input current.

Addressable RGB fan and long cables

A 14 cm RGB fan with intelligent speed control offers multiple lighting modes and power-off memory. Honeycomb ventilation assists heat dissipation while the fan runs quietly. Cable lengths of at least 500 mm support bottom-mounted PSU layouts in large cases. Fully modular cabling reduces clutter and improves airflow.

Questions about this item

How does the 850 W rating translate when the unit is installed in a real system?

The 850 W maximum power is delivered on a single +12 V rail, giving stable DC output for high-end graphics cards and the rest of the build.

What does the 80 PLUS Gold certification actually cap in everyday use?

It guarantees at least 90 % efficiency at typical loads, so less waste heat and lower electricity draw.

What clearance is needed to fit the 170 mm length in a case?

The unit measures 170 mm long and cables are at least 500 mm, so it suits bottom-mounted ATX cases with that depth.
