## Overview

The Silverstone SX500W SFX-L power supply delivers 500W of reliable power in a compact 120mm fan-cooled chassis. Its 80 PLUS Gold certification guarantees 87%-90% efficiency, while fully modular flat cables simplify installation and upgrades. Designed for small form factor enthusiasts, it supports both SFX-L and ATX cases via an included bracket, combining silent operation with versatile compatibility.

## Description

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.

Review: Silent and very powerful 700W in a SFX-L form factor power supply. - The Silverstone SST-SX700-LPT-USA is a great 700W power supply. Its a completely modular power supply and the cables are easy to work with. I used this particular model in an ITX build paired with a 10700k and 2080 Super graphics card. The power supply was able to handle the power requirements of the cpu and gpu just fine. One thing the buyer needs to note is the fan within the power supply will not spin on turn on. The fan only comes on when a certain temperature is reached within the power supply. So its very silent. And only comes on when I game. But then I can not even hear it. Everything was in the box i needed and came very well packed.
Review: (Silverstone SFX-L) For when "Go big or go home" doesn't apply - This will be my first time building a mini itx computer making it my third pc build. Wanted to maximize space and increase airflow so choosing a SFX power supply in my mind was a no brainer. The reason for choosing this power supply was based on the original case I had in mind for this build which was the Silverstone ML08B-H. Loved the slim design and the fact that it had a carrying handle. However I decided to go with a Cooler Master Elite 130 do to its support for all in one liquid coolers and better airflow. Even after changing cases I already had my mind set on this awesome little power supply. It also comes with an adapter to mount on an ATX case so it will fit just fine in the Elite 130 case. I'm use to using power supplies that come with sleeved cables however I am glad it came with flat cables so it is easier to work with inside cramped spaces. If you are building a mini itx computer I highly recommend this power supply by Silverstone. Small form factor without having to use a smaller fan Included mounting bracket Flexible Black Cables Fully modular for easier upgrades and maintenance. (Used non modular power supplies and will not go back) Zero RPM fan for silent operation And of course the pimpin snowflake on the fan grill

## Questions & Answers

**Q: Anyone have issues with a wobbly fan? This PSU runs extremely silent, however the fan wobbles ever so slightly and causes a rubbing/rattling sound.**
A: NOTE: This answer pertains to the 500W SFX-L model only. I hate to say it but you're not alone. Check out some of the 1 and 2 star reviews. Also if you google this particular PSU you will find others complaining about the noise (clicking/rattling/buzzing etc). The good news is the problem is an anomaly and only occurs in some of the units being shipped. Others claim their PSU makes no noise at all. In my case I also noticed the wobbly fan but as it turns out my PSU made the same noise even when the fan was not running. Another reviewer described it as sounding like a hard drive doing read writes and hearing the hard drive activity. That's actually a pretty good description of what I was hearing. Fortunately I noticed the problem within days of receiving it, and also fortunate because  I purchased mine from Amazon. Amazon made the exchange process for a new one as painless as it could be. Thanks Amazon!

**Q: are the cables long enough to use in fractial design nano s case? (500sfx-L)**
A: Yes. I use it in that case

**Q: Are the pin-outs of the 500w SFX-L the same as the Silverstone SFX's? I have cables that fit the older SFX ,and want to use it for the new 500 SFX-L.**
A: Yes, they are interchangeable.  Replaced a few older SFX's with a newer SFX-L without problems.

**Q: Does this include the power cables plug into wall outlet?**
A: Yes. That said, I would look elsewhere, as mine died within a week. I opted for the FSP Dagger which imho is a much better unit.

### ⭐⭐⭐⭐⭐ Solid PSU!
*by E***G on May 26, 2022*

So far this power supply has been super solid. No issues after a couple of power outages, and seems to put out consistent power. Easily powers high end hardware with no unexpected shut downs. Only negative I have with this thing is the whining. You can here it depending on the power draw, a high pitch whine coming from it. It doesn't bother me, because I usually have headphones on most of the time, but just something to be aware of. Overall, happy with my purchase. I have always trusted Silverstone power supplies and actually have one 10 years old that's still going strong.
