Corsair CP-9020310-NA CX650M 650W power supply

Power delivery for modern GPUs

The Corsair CX650M is a 650 W ATX 3.1 power supply built to the PCIe 5.1 standard. It targets builders who need a native 12V-2x6 cable for current graphics cards without using adapters. The semi-modular layout keeps the essential cables fixed while letting you add only the extras your system requires. Cybenetics Bronze certification and 105 °C capacitors support stable output over a long service life.

Native cable and modular flexibility

A factory-fitted 12V-2x6 connector removes the need for adapters when installing RTX 40-series or 50-series GPUs. The semi-modular design means peripheral and storage cables can be omitted entirely, reducing clutter and improving airflow inside the case. ATX 3.1 and PCIe 5.1 compliance ensures the unit meets the latest power-excursion and timing requirements for modern components.

650 W capacity with strong GPU headroom

The 650 W rating delivers up to 450 W through the single 12V-2x6 cable, covering the RTX 5070 and 4070 families with margin. Builds targeting an RTX 5070 Ti or RTX 4080 would exceed the per-cable limit and need a higher-wattage model. The 105 °C capacitors help maintain output quality under sustained loads, but total system draw above 650 W is outside the unit's specification.
