## 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.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Like an idiot
*by A***. on June 10, 2018*

I write this review after 2 years of heavy use of 500W SFX-L in my Mini-ITX machine.Recently the power supply cable was slightly pulled and not all the way in which caused some blue sparks coming out of the back of the power supply. Like an idiot, it took me a while to process what was happening, and before I knew it I smelled hot copper and the system shut down. It wouldn't boot back up, not even after 20 mins.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.**UPDATE**It's 2020, 4 years later, in a hotter climate with worse electrical current and still going strong.

### ⭐⭐⭐⭐⭐ Silent and very powerful 700W in a SFX-L form factor power supply.
*by E***N on September 3, 2020*

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.

### ⭐⭐⭐⭐⭐ Almost 100% completely silent operation.
*by M***E on February 1, 2021*

This fully modular power supply is very tolerant of warmer temperatures and as a results rarely needs to operate the fan. In fact when I say rarely, in my case it is pretty much never. I thought perhaps my fan was not working, but it simply does not need to operate within normal operating parameters. I have a Ryzen 3900x, 1080 GPU, four DDR-4 modules, a Vive Wireless adapter, M.2 WiFi, NVME, and SATA SSD running on an Asrock x570m Pro4 motherboard in a Sliger Cerberus case and, even under heavier loads, the power supply fan simply does not need to operate. The only fans I hear running are the CPU and chipset fan. I am extremely happy with the purchase and would more than likely look to purchase this again in a future build. The smaller size of this SFX-L power supply gives me a lot more flexibility in mounting it and has really opened up the space to work inside the case. Due to the extreme flexibility of the Sliger Cerberus (best case I think I have ever purchased) I have the power supply mounted in the front of the case drawing outside air in and exhausting out the top of the case. The natural convection in this orientation assists in the silent operation. If I had to buy another power supply today, I would get this exact same model.
