CX650 650 W ATX12V power supply

The Corsair CX650 delivers 650 W of continuous power through a single +12 V rail rated at 54 A. It uses an ATX12V / EPS12V form factor with a non-modular cable set that includes a 20+4 pin main connector, two 6+2 pin PCIe connectors and six SATA connectors. The unit is 80 PLUS Bronze certified and operates on a 100 to 240 V input range.

Thermally controlled 120 mm rifle bearing fan

A 120 mm thermally controlled rifle bearing fan adjusts speed according to load and temperature. The platform is engineered to meet its maximum power output at a 40 °C operating temperature. LLC resonant topology with DC-to-DC conversion maintains efficiency at lower loads while active PFC and over-voltage protection help stabilize output during sustained demand.

Non-modular Bronze upgrade for mainstream builds

The CX650 replaces older or lower-efficiency units in standard ATX cases with up to 140 mm of PSU clearance. Its black housing, sleeved cables and 100,000 hour MTBF suit system integrators and DIY builders who want Bronze-grade efficiency without modular cable management. The jump is worth it when moving from unrated or White-rated supplies to a Bronze platform with full-range AC input and a five-year warranty period.

Questions about this item

How loud is the 120mm thermally controlled rifle bearing fan when the CX650 runs all day under load?

The 120mm thermally controlled rifle bearing fan adjusts speed based on temperature, keeping noise low at typical loads and ramping up only when the unit approaches its 40°C operating limit.

Which cables are permanently attached to this non-modular CX650 that I must route in my case?

The fixed cables include a 20+4-pin ATX connector, a 4+4-pin EPS connector, two 6+2-pin PCIe connectors, six SATA connectors and four four-pin peripheral connectors.

Will the single +12V rail delivering 54A work with an older motherboard that uses a 20-pin main power socket?

Yes, the 20+4-pin main connector splits to fit a 20-pin socket, and the single +12V rail at 54A is compatible with both legacy and current platforms.
