The ASRock Steel Legend SL-1200 is a reasonably small 1200W supply, measuring 150 x 85 x 150mm – this means it will fit into a huge variety of chassis designs. Some 1200W power supplies can be physically large which can limit their installation compatibility.
I have to admit I do like the styling of this power supply, it's a matte white which is certainly more eye catching that the plain matte black version. There are some nice stickers and layout decisions around the panels, although I do have to admit the ‘S' logo on the top of the unit, in the center of the fan, reminds me of the ‘Superman' logo a little.
If you pay close attention you will see the edges of this design are rounded and the mesh style grille looks great as well around it. We will take a closer look at the fan shortly when we open the supply.
The modular bay is split over two rows and it is clearly labelled for ease of installation.
The other side of the chassis is home to the power switch and connector, with a mesh grille to aid airflow. At the other side is a button to enable and disable the intelligent fan mode. This is something we have seen a lot of manufacturers adopt in recent years. Intelligent mode, we noticed, also seems to increase fan speed a little at higher load demands, which is interesting.
The power supply is able to deliver 100A across the +12V rail, and 25A across both minor rails. Total power output is set at 1200 Watts.
