SilverStone's SFX-L Power Supply Series
SilverStone offers two product lines within its SFX-L family of power supply products: SX for units with a 120mm fan, and the exclusive Nightjar (NJ) series of silent, fanless models.
The SX500-LG takes advantage of the versatile SFX-L form factor
For small form factor enthusiasts, standard SFX power supplies offer an excellent combination of size, power, and affordability. At 100mm deep, however, they are limited to 92mm fans. SilverStone longer variation of the SFX form factor called SFX-L. At 130mm long, an SFX-L power supply has space for a 120mm fan, thus its maximum load noise is not only lower in intensity (due to a slower fan speed), but also lower in pitch (due to larger fan size).
- Silent running 120mm fan with 18dBA minimum
- Includes an ATX adapter bracket for installation in larger cases that do not have SFX mounting holes
- Utilizes all Japanese capacitors
Efficiency and power in one package:
The 120mm fan has excellent airflow and low noise, perfect for quiet home or office use. Note that version 2.0 of the SX500-LG removed the semi-passive mode of the version 1.0 model while improving the overall actively-cooled noise level.
1 x 24/20-Pin motherboard connector（300mm)
1 x 8/4-Pin EPS / ATX 12V connector（400mm)
2 x 8/6-Pin PCIE connector（400mm / 150mm)
3 x SATA connector（300mm / 200mm / 100mm)
2 x 4-Pin Peripheral connector （300mm / 200mm)
1 x 4-Pin Floppy connector（300mm / 200mm / 200mm)

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.

I have this PSU in a Lian Li PC-TU100B, which previously housed the Silverstone ST45SF-G. My issue with that PSU is exactly what Silverstone describes in the "Product Description" of SX500-LG - the high-pitched noise. It was not loud, but was very noticeable and thus extremely annoying. The SX500-LG addresses that exact problem with a larger fan and a less aggressive fan curve.
Before purchase you need to make sure that it fits in your case because the SX500-LG is longer than a standard SFX PSU.
Other features that I like:
- Flexible cables, similar to the PP05-E set
- Native support for dual 6+2 pin PCIe power connectors
- The ATX bracket included has a better build quality
I assumed the pc died. Either the PSU blew up or the MOBO was fried. But the next day I when I tried to turn it on again, it was working and just like new! Turns out it was some sort of safety mechanism by the the SilverStone PSU that prevented the system from booting if the temperature is too hot and it prevented the system from being fried when it sensed a large electrical discharge.
On top of all that, after 2 years and this incident, it still runs smoothly and silently and keeps the system cool.
Worth. Every. Penny.
It's 2020, 4 years later, in a hotter climate with worse electrical current and still going strong.
On the plus side, I purchased mine from Amazon. You can't ask for a better company top deal with when it comes to issues like this. The return was processed and a new one shipped out. No muss, no fuss. If the replacement unit is silent I'll be happy... if not I'll report back here to let everyone know.
UPDATE - DEC 11, 2015
Found a forum where Silverstone was discussing the noise issue. As a result of the statements made I may discover a replacement PSU isn't going to fix the problem for my specific installation. I'll report back once I get the replacement fan installed. Hopefully I'll get lucky.
Here's what the Silverstone rep had to say:
"The SX500-LG's uses temperature based fan control... We believe the ticking noise that some owners of SX500-LG heard is the result of the ramp up in voltage applied to the fan by the temp control. This is more noticeable around the voltage required to start the fan."
UPDATE - DEC 13, 2015
Received the replacement 500W SFX-L from Amazon. This one is dead quiet... no noise of any kind! Sweet!
UPDATE - DEC 16, 2015
Bad news... Three days of perfect function... then it failed. Just up and died in the middle of making some updates. Swapped the replacement with a known good supply and everything was fine, put the bad one back in and nothing... Dead. Believe it or not this failure isn't much of a concern as I'm aware any electronic item can fail... TV's, Receivers, Blu-Ray players etc. Plus, I was unable to find anyone else who reported the same type of problem. I contact Amazon for another replacement.
UPDATE - DEC 20, 2015
Received the replacement from Amazon. Thank God I ordered from Amazon and not some other online outfit. From years of buying computer parts online I know any other company would not have been as customer oriented as Amazon. From experience, other computer parts company's would have been blaming me... or making me file a warranty claim with the manufacturer.
The good news... I'm up and running again. The not so good news... this one is not silent as the one that failed but it is a lot quieter than the first one. Where the first PSU made loud clicking sounds... this one is more of a quiet squeak. Sounds like a baby mouse in the unit... or a noise like dry fan bearings... squeak, squeak, squeak. However, the squeaking sound occurs when the fan is not spinning. Once the fan kicks in and starts spinning the squeaking stops. That said, I'm going to cut my loses and just keep this one. Amazon has been more than fair and has gone above and beyond in helping me with this PSU. Besides it's not the end of the world, I can't hear it once I get a couple feet away. As mentioned in my Dec 11th update, the noise issue is a known complaint among some customers but per the manufacturer the PSU is working as designed and depending on the application, you may or may not experience some noise.
NOTE: If you must have a Silverstone SFX-L form factor PSU... and can wait a week or two, Silverstone is getting ready to release a 750W SFX-L, and it's Platinum rated! Plus, the fan control circuit has been redesigned which should address the noise issue that seems to plague this unit.
80 Plus Gold
Relatively quiet fan (even without the zero RPM fan mode of the v1 version)
Flat black cables
Slightly larger SFX form factor (130mm doesn't leave much room in my FTZ01 for dealing with the cables)
The V2 of this power supply doesn't really have much different than it's original counterpart. The main change with the V2 version is the removal of the Semi-Passive fan mode of the v1. There were several complaints about the fan making a "grinding noise" and some buzzing as well but this issue seems to have been severely reduced with the V2 PSU.
Overall this is a very nice small power supply. It is a bit larger than the standard SFX form factor so that is definitely something to keep in mind, however as a result they were able to slap on a larger 120mm fan which definitely helps keep this thing cool and quiet. This is a solid little power supply with 80plus gold efficiency that gets the job done.
More so than not the fan will make an odd noise, kinda like the sound of a writing HDD. It is noticeable and annoying. I thought for sure the fan was bad, so I RMA'd it. Next one did the exact same thing. So I started looking online into this issue, several posted videos of people having this issue with this model PSU, same issue, read through the comments and they too have tried the RMA route with no resolve. I ordered an ultra slim 120mm fan from scythe, others from rosewill, and those two brands with an adapter taking the 3 or 4 pin cable down to 2 will work and works great. But it's extra money, extra time, and breaking the warranty seal to do so. So keep this in mind with this PSU, SilverStone dropped the ball with the fan.
After replacing the fan, it's fantastic. Two stars because the fan is an important piece of this and the main reason to get the L series.
