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-fanless 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.

To cater to a growing class of enthusiasts with more than one system making up a main system, Phanteks rolled out he Enthoo Mini XL. This full-tower chassis has room for two motherboards, an ATX, and a mini-ITX. With three 5.25-inch drive bays, and two stacks of 4-tray 3.5-inch/2.5-inch bays, that can be detached to free up room for a tall radiator, the case can house two full-fledged systems, that are interconnected over network and KVM. There are two power supply bays, one that's standard ATX, and another that's SFX. Phanteks set up what's one of many build ideas for you to buy this case for.

SilverStone's latest addition to its space-efficient SFX-L form-factor PSU lineup, is the 500-Watt SX500-LG. This fully-modular PSU boasts of 80 Plus Gold efficiency rating, and enough cabling to power a gaming desktop, with a single high-end graphics card. It features a single +12V rail design, APFC, and most modern protection mechanisms. A 120 mm fan is used, to keep it cool. Cabling includes two 6+2 pin PCIe, a 4+4 pin EPS, 24-pin ATX, three SATA, two Molex, and one Berg. SilverStone is expected to launch this PSU later this month.

Placement horizontal or vertical makes our PowerCube chassis great for home or office use. No matter the challenge, the PowerCube chassis will be sure to deliver what you want, when you want.

Japanese PC hardware maker Dirac launched its Tesla Cube line of high-wattage PSUs in the SFX form-factor. The series includes 550W and 650W models, which should splash your build with enough juice to run single high-end or two performance-segment graphics cards. The two feature single +12V rail designs, efficiency that meets 80 Plus Gold standards, and a fully modular cabling design. The two also come with adapters that let you install them on standard ATX cases. Cables for both models include 24-pin ATX, 4+4 pin EPS, two 6+2 pin PCIe, six SATA, and one Berg. The 650W Tesla Cube displaces Silverstone's SX600-G in being the most powerful SFX power supply. Silverstone's unit was showed off at Computex 2014, and is headed for launch later this month.
