The AC inlet of this power supply can be rotated a full 90-degrees, facilitating two orientation layouts. Thanks to this, you can adjust your PCs cables to match your case. If your case has ample space in the PSU chamber, you can opt for the Standard Orientation, where your wires need to be pre-connected when installing your PSU. However, if you’re limited on room, you can use the Rotated Orientation, where you’ll have direct access to the ports, giving you more freedom to plug your cables in as you need them. A Modern Modular Design To support the rotatable design, the Lian Li RS Series 1200W PSU features an innovative modular layout. As an ATX 3.1 power supply, the RS Series includes a full range of power outlets, including a native 12V-2x6 connector. However, in place of a standard 24-pin motherboard connector, this PSU includes two dual-side outputs, one on either side of the PSU chassis. As a result, clutter is reduced around a single location, facilitating easier access to all your ports.
