Product Description

For small form factor enthusiasts, the standard SFX power supply form factor has excellent combination of size, power, and affordability. At 100mm deep, however, the standard SFX PSU is also limited in fan size to 80mm. While advances in engineering and components have made modern high-end SFX PSUs quieter than ever, there is still inherent limitation with 80mm fan's ability to dissipate heat at maximum loading conditions while maintaining satisfactory noise profile for users sensitive to higher-pitch sounds. With this in mind, Silverstone has released a "lengthened" variation of the SFX form factor called, SFX-L. With 30mm of added depth, a SFX-L power supply has enough room to fit a 120mm fan, thus its maximum load noise can be not only lower in intensity (via slower fan speed), but also lower in pitch (due to larger fan size). The first model to debut in the SFX-L will be the SX500-LG, a 500W model that includes all features available from top of the line SFX Silverstone PSUs such as 80 PLUS Gold efficiency, modular flexible flat cables, and semi-finless capability. An ATX adapter bracket is included as well to enable users to install this PSU into any small or even larger cases that do not have SFX mounting holes.

Products made by SilverStone don't play well together
I bought this because it was the smallest modular SFX-L PSU SilverStone made and I wanted it to match with the new SilverStone Case (ML08B-H) I purchased. I wanted the SFX-L for the larger fan and cooler operation. These products are both made by Silverstone and don't work together, very disappointed.1. The length between the SATA power supply cable connections isn't long enough to bridge between the 2 drive bays.2 My ITX Motherboard has the main power connection to the right side of the CPU (as some do) and the supplied cord is 'just' long enough to reach. Not allowing proper routing.I'm continuing the build using the PSU because I can live with these issues (only 1 drive needed), but I may update this review if the thing fails or some other disaster occurs because of its design flaws.Adding photo of cables. Basically, you can connect 1 drive out-of-the-box and would need additional adapters to connect more.
