Solid power supply
Needed new power supply for the upgraded Geforce RTX4060 low profile card I got for my Lenovo desktop, so got this SilverStone SFX version. Seems perfect and is much smaller than standard ATX and allows for more room in the case. I use it with SFX to ATX bracket (PP08B). Power supply is super quiet, PC inside temperature is low so everything seems to run very efficiently. Bit expensive yet I still think it's well worth it, hopefully will last many years.

Works perfect and whisper-silent in a Ghost S1 with a 5800X and 6800XT!
Keeps the demanding hardware in this teeny tiny case fed with clean, stable, delicious power. Virtually silent at all loads. Cables are a bit long for an SFX PSU, but most people end up getting braided or silicone custom length cables (check the e of bay, they're worth the $50 or so). Handles a 5800X and an unlocked 6800XT, both heavily overclocked, without breaking a sweat.

True SFX
True SFX form factor, turned out to be smaller than I expected. For the wattage and efficiency rating, this is a very compact PSU, exactly what I was looking for. The cable lengths are strange, the EPS 12v is loooong but the ATX 24-pin is relatively short. I've had it running for a week and a half so far without problems, though I'm currently only running it at half capacity max. Will be upgrading my PC with more power hungry components in the next week or two. I like that it does not have a "fanless" mode, which caused problems in previous Silverstone models. The fan still spins at low loads, but is virtually silent.

Dead on Arrival
This power supply is absolute garbage. Apparently SilverStone has zero QA and their claimed burn-in process is a lie. Imagine my frustration trying to get a defective power supply to power up my PC when it never worked to begin with. Thankfully I had an old power supply laying around to confirm that it was the SilverStone and not my build that was broken. Other than that, the cables that come with this power supply are the worst I've ever seen. They're flat and have very little flexibility, and what little movement they have is in two directions (e.g. up and down, but not left or right) due to this ridiculous side-by-side flat cable configuration. They're also very long which usually isn't what people want when they're buying a small form factor power supply. In the end I returned this product and purchased a Corsair SF series which is far superior in every way. Not only did it power up immediately with zero issues, it also has very high quality, individually wrapped cables that are a joy to manage. Don't think you're saving anything by buying this SilverStone unless you want to gamble wasting time on a return in the worst case or fight the awful cables in the best case. I wish I could give this zero stars. You have been warned!

A very good option to the overpriced Corsair 750w
The difference of 50w doesn't really mean that much so this unit can do same job. The cables are a little thick, but I managed to make them fold and disappeared inside of a very small sandwich style case. This powers an I7 10700 (125W), RTX 2070 super, 32gb ram, 2gb nvme. The noise level is not louder than the one of the gpu or cpu, and I have my pc next to me on top of the desk.

Very efficient, loud fan(I will be switching it to a noctua fan), Very stiff cables!
The power supply itself is great and I'm sure it'll last me years. I wish the fan had better control but if you know what you're doing you can easily swap the fan out for something better. The cables are extremely stiff which made it hard to work with in my node 202 so I will have to pick up some custom cables unfortunately. Overall I am happy with it though and I just want other potential buyers to understand the flaws.

Bought in 2021. Works perfect since than
Since 2021 works perfect with no issues. My PC is i5 10600k and RTX3070ti Gigabyte Eagle. Even though it's less than the recommend wattage for 3070ti, it seems like there's no issues.

Great PSU, Terrible Cables
Do NOT pair this PSU with a 300+ Watt GPU unless you intend to replace the PCIE cables. Attached is a picture of a burned out PCIE connector and the low voltage at the GPU inputs it was causing. There is another reviewer here that shows a picture of a fully melted connector on the same pins. I replaced my included PCIE cables with the 30$ “premium” Silverstone PCIE cables, and now it holds 12.1-12.2V under a 300W draw. Just buy the Corsair SF750. It’s the same price and it doesn’t have this major flaw.

Works great and was able to run my 6800xt without any problems. The real trouble came with the cables that were in the box, instead of sleeved cables you'd expect from platinum power supplies you get standard cables that aren't flexible at all.

No complaints whatsoever

Silverstone managed to make one excellent sfx unit with very high power density, but please Silverstone change the OEM for your fans, they are so loud. I used an SX 500 G before and that was also very loud. Swapped the fan with a Noctua A9x14, PWM controlled via motherboard and it's whisper quiet. These platinum PSUs produce significantly less heat, a lower RPM/quieter fan would've made it perfect. Other than that, unit has been running flawlessly for over 2 months with the Noctua supplying it with fresh air.

The unit itself fits perfectly, but the cables makes me want to return the psu. I have to agree with another buyer comments. the cables are incredibly stiff. licorice candy left on the counter has more flex. Will review comment once install is complete
