Seasonic X-Series 660W compatibility review

The Seasonic X-Series 660W power supply has a maximum wattage output of 660W. 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 Seasonic X-Series 660W has an 80 Plus rating of Gold. This means the PSU operates at average efficiency levels of at least 87%, 90%, and 87% for loads of 100%, 50%, and 20% respectively. Gold is the second-best 80 Plus certificate available, and as such the Seasonic X-Series 660W is extremely efficient and comes highly recommended. The actual efficiencies for this PSU are 88.23%, 90.94%, and 88.61%, for loads of 100%, 50%, and 20%.

The dimensions of the Seasonic X-Series 660W (LxWxH) are 16cm x 15cm x 8.6cm. Make sure to compare these measurements against the case you desire if planning on using it in a build.

The Seasonic X-Series 660W is modular, meaning that cables can be taken out and connected back in as necessary. This can make cable management much easier, leading to a less chaotic build, and better airflow.

The Seasonic X-Series 660W is designed for low volumes, meaning that its constant drone while your PC is on would be less noticeable - ideal for those that prefer silent environments.
