Who Should Consider It?
This model suits builders whose calculated system power needs, required connectors and case layout match its output and form factor. The RS design is intended for users who want flexible standard or side-mounted installation and a rotatable AC inlet.
For a lower-power or compact build, compare the required wattage, PSU dimensions and connector layout before choosing a model. The correct PSU depends on the complete component configuration, not just the graphics card.
