750W full-modular ATX power supply

The Corsair RM750X delivers 750 W through a single +12 V rail rated at 62.5 A. It meets ATX12V v2.4 and EPS 2.92 standards and carries 80 PLUS Gold certification with 90% typical efficiency. A 135 mm rifle-bearing fan runs under thermal control for quiet operation.

Full-modular cable set included

Every cable detaches from the unit so builders connect only what the build needs. The box supplies a 20+4-pin motherboard cable, a 4+4-pin CPU cable, four PCIe 6+2-pin connectors, eight SATA connectors, seven peripheral connectors and a floppy adapter. This reduces clutter and improves airflow inside the case.

Suited to mid-range multi-GPU systems

The four PCIe 6+2-pin outputs support SLI and CrossFire configurations, while the single +12 V rail simplifies power distribution. Builders needing higher wattage or different connector counts should consider other models in the range.

Questions about this item

Will the 750 W unit deliver enough power on the +12 V rail for a high-end graphics card?

The single +12 V rail provides 62.5 A, which equals the full 750 W capacity, so it can handle demanding GPUs without splitting current across multiple rails.

Does the fully modular design include all cables needed for a typical ATX build?

The box supplies a 20+4-pin motherboard cable, a 4+4-pin CPU cable, four PCIe 6+2-pin cables, eight SATA cables, seven peripheral cables and a floppy adapter.

What does the 80 PLUS Gold rating mean for daily electricity use?

The unit achieves 90 % efficiency at typical loads, so less power is wasted as heat and the fan can stay quiet longer.
