SilverStone Announces SX500-LG Power Supply


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.

Special Features:

  • Silent running 120mm fan with intelligent semi-fanless operation
  • Support SFX-L form factor and ATX via included bracket
  • High efficiency with 80 PLUS Gold certification
  • 100% modular cables
  • All cables made with flexible flat arrays
  • 500W continuous power output at 40? operating temperature rated for 24/7 operation
  • Class-leading single +12V rail with 40A
  • Strict ±3% voltage regulation and low ripple & noise
  • Support dual PCI-E 8/6pin connectors
  • Active PFC

The recommended End User price (excl. VAT): $89.11 USD. The SX500-LG will be available in our stock on the 28th of January.

My Thoughts

SFX PSUs will no doubt allow us to produce even more compact systems in the future, but only when we see cases which properly support them. This presents a weird "chicken and egg" problem which will no doubt will be fixed within the next few years but right now the SFX PSU size will severely limit you when it comes to case selection.

The biggest change Silverstone has made to their SFX PSUs in my eyes is the chance to a 120mm fan, from their rather noisy 80mm fan used in their older model. THis change will result in a decrease in noise levels as the 120mm fan will need to spin a lot slower than a 80mm fan to provide the same airflow.

not with these PSU's expect to see powerful compact systems quieter than ever before?

It's an interesting development that makes a lot of sense, it's really the reduction in height that makes SFX PSU's ideal for compact builds so the extra length should be a welcome trade-off for a little less noise. I'm excited, I would definitely consider these in the future, hopefully they do some 6-7-800watt versions for some tighter packed mATX builds. I hope DTX becomes a thing too.

I wish the ATX brackets that were included offered an offset for mounting instead of placing the PSU in the center of the bracket. I've used several Silverstone SFX psu's in lower power requirement SFF rigs that benefited from the smaller PSU size in the normal ATX PSU space to gain CPU cooler height clearance.Quote
