Review of SilverStone SFX SST-SX500-LG V2 500 Watt [SST-SX500-LG V2.0]
Without exception, the power supply cables are modular, so you can leave only those cables, that are necessary for the operation of the system. This feature is especially relevant for compact computers.
One of the main advantages of the power supply are the capacitors manufactured by Japanese companies: Rubycon (high-voltage) and Nippon Chemi-Con. In addition, there are some of polymer capacitors installed in the power supply unit.
Among the main advantages of the power supply are also considered excellent acoustic ergonomics, decent electrical characteristics. Among the shortcomings are short wires and a small number of connectors for connecting components, which can be critical when installing a power supply unit in large enclosures. Also, the fan on the sliding bearing is alarming, the resource of which hardly exceeds the warranty period of the power supply unit.
The technical and operational characteristics of this model are at a good level, which is facilitated by the high load capacity of the channel + 12VDC, high efficiency, low thermal load, capacitors of Japanese manufacturers. Because of this, the SilverStone SFX SST-SX500-LG V2 500 Watt can live a fairly long life with high constant loads.
The cooling is a 15 mm fan S1201512MW (1800 rpm) size 120 mm, made on the basis of a sliding bearing from the Taiwanese company Globefan Technology.
There is also an adapter In the power supply kit that allows you to install a power supply unit with an SFX mount in a housing designed for ATX power supplies. Let me remind you that buyers of non-standard power supplies from Sea Sonic will have to buy an additional adapter plates in order to install them in an ATX-case.
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 all Japanese capacitors. 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.
Designed for 80 PLUS Gold level of efficiency to reduce wasted heat and save on electricity.
100% modular cable design for easy removal in a case with cable routed and tied down.
Flat cables have much greater flexibility to allow for tighter folding and management of cables.
±3% regulation and low ripple & noise performance for high stability.
Powerful single +12V rail design, perfect for future high-end component upgrades or overclocking.
Built-in 120mm fan has excellent airflow and low noise, perfect for quiet home or office use. (V2.0)
Buyers in their reviews recommend this power supply, as the cheapest version of SFX format with 500W and certification 80+ Gold. According to user reviews, this power supply is ideal for building a compact and powerful computer. SilverStone, along with Sea Sonic, enjoys maximum confidence among buyers in the whole world.
Disadvantages. Despite the manufacturer’s assurance of the noiselessness of its device, in fact it is almost always operated with the cooler turned on (the turn-on threshold is 41 * C), and the sound from it comes from very tangible.
This PSU worked exactly as I expected. Quiet (if not silent), flexible cables, well made.
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
Amazon’s customer positive review
As others have warned… be sure to check this power supply in operation when you receive it, or as soon as you can before the return period expires. When it’s in quiet / silent mode, the fan does not spin and is silent… but… once the fan turns on the noise is unacceptable. As others have reported it makes a rattling or clicking sound. When looking at the fan when its running the fan blade appears to have a slight wobble! After it runs for a while the sound fades down to a more tolerable level but you can still hear it from 5ft away. This is not acceptable for something advertised as “Silent Operation”
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.
