The Kingwin ABT-650MM 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 Kingwin ABT-650MM has an 80 Plus rating of Standard. This means the PSU operates at average efficiency levels of at least 80% for loads of 100%, 50%, and 20%. Standard is the lowest 80 Plus certificate available, but with 80% load efficiency minimums, the Kingwin ABT-650MM is still reliably efficient and is by no means a bad PSU choice.

The dimensions of the Kingwin ABT-650MM (LxWxH) are 14.5cm x 15cm x 8.5cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The Kingwin ABT-650MM 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 Kingwin ABT-650MM 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.
