A Closer Look
The PSU comes in a standard ATX form factor and measures 150mm x 150mm x 86mm in dimension. As you can see from the label, the PSU features a powerful +12V single rail at 100A which gives you a maximum power output of up to 1200W.
For cooling it uses a 135mm Striped Axial FDB fan, and comes with ASRock’s iCool Intelligent Fan Control Mode for quiet operation.
Interestingly, the SL-1200GW power supply is certified Cybenetics PLATINUM with LAMBDA A+ ratings. You’re probably asking what is this? Well, it’s a recognised certification for power supplies that high-light performance, build quality, reliability and noise level. For more information about Cybernetics and LAMBDA go here.
Installation
For our tests, we installed the PSU on to our vertical open chassis. No issues with installation, everything fitted nicely.
The flat modular cables allow you to achieve more air-flow within your chassis. They’re clearly labelled and easy to plug in. The package also includes some cable ties and velcro straps for cable management.
To power the GeForce RTX 4080 SUPER we used the included 16-pin 12VHPWR cable, which has a Dual Color Design and is rated up to 600W.
