Cooler Master GX-650W RS-650-ACAA-D3 compatibility review

The Cooler Master GX-650W RS-650-ACAA-D3 power supply has a maximum wattage output of 650W. This is a decent capacity, and should be fine at handling the majority of mid-performance PC builds, but you could find yourself in trouble if you do not make certain of its capability to power any proposed build. Remember that a higher PSU capacity does not necessarily equate to a higher wattage output and a more expensive electricity bill. In fact, you may find that a higher capacity PSU will function more efficiently than a lower capacity PSU because it is dealing with a lower percentage of its maximum load - that is, it is not being stressed to the same extent.

The Cooler Master GX-650W RS-650-ACAA-D3 has an 80 Plus rating of Bronze. This means the PSU operates at average efficiency levels of at least 82%, 85%, and 82% for loads of 100%, 50%, and 20% respectively. Bronze is the fourth-best 80 Plus certificate available, and as such the Cooler Master GX-650W RS-650-ACAA-D3 is very efficient and is a decent PSU choice. The actual efficiencies for this PSU are 82.35%, 86.40%, and 85.43%, for loads of 100%, 50%, and 20%.

The dimensions of the Cooler Master GX-650W RS-650-ACAA-D3 (LxWxH) are 15cm x 14cm x 8.6cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The Cooler Master GX-650W RS-650-ACAA-D3 is not modular, meaning that cables are built into the PSU itself and cannot be taken out and connected back in as necessary. This can result in difficult cable management and consequently a messy build and poor airflow.

The Cooler Master GX-650W RS-650-ACAA-D3 is not designed for low volumes, meaning that its constant drone while your PC is on could potentially be noticeable and irritating, though this may only be a problem for those that require silent environments.
