SFX-L V2.0 500W '80 Plus Gold' Fully Modular 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.

Yes, it is silent!

As the first reviewer said, this is silent! I have it open on the desk with only a couple of very quiet fans otherwise to hear, and can't hear the PSU at all. Also remains quiet under a higher load while gaming.

It comes with flat modular cables, so no need to get them as an addition. The only downside I can see is that there are only 3 SATA power connectors, but if this is a problem you could use an adapter on one of the 4-pin molex connectors.


Super Silent with no weird sounds

This is a great PSU , Zero RPM Mode tell after 34mins on desktop , no weird sounds befor the fan started up , it was super silent , The Temperature Sensor works well , if i blow air at the fan it will stop for alittle time , only 30mm more Depth giving us a super silent 120mm fan , Great PSU from Silverstone & Thank you OcUK once again for the great Service & Swift Delivery by DPD.
