Product Description
After successfully revolutionizing both HTPC and SFF market segments with innovative chassis designs, silverstone engineers continue their push for advancement in these categories by releasing a true upgrade-worthy small form factor power supply, the st45sf. This SFX unit is compatible not only with chassis that use SFX power supplies but also in smaller ATX chassis with the included adapter bracket. Despite its small size, the st45sf has features that one would expect from an Elite ATX power supply such as 80 plus Bronze level of efficiency, temperature controlled fan, 50℃ temperature rating, and reliability for 24/7 operation. Enthusiasts oriented features are also present with single +12V rail and 8pin/6pin PCI-E connectors to fully support multi-GPU systems. For SFF users and for silverstone, the st45sf is more than just an upgrade, it is an important milestone for the DIY desktop computer.

After the power supply failed in my old Lenovo Thinkcenter, and the apevia replacement unit failed after 2 hours, I was so happy to find a product that worked. This power supply lasted me through 2 computers, and still worked when I gave it away. The only reason I replaced it was because I decided that having my pasu stick out through the 5 1/4 bays on my second computer looked tacky. Over all, I highly recommend this power supply to anyone who wants something to last a long time and never fail.

I've had proprietary PSUs before, but not very often... stuff like Shuttles, or microATX builds. I was only vaguely aware of the SFX form factor, but was excited when I found out about adapter plates you could use for a regular ATX PSU mount. The ST30SF wasn't the cheapest option, but it was the lowest cost unit that had a brand I trusted and had the adapter bracket (otherwise you'd have to spend like $10 to get one). As you might imagine, the unit is tiny. The bracket centers the unit within the ATX cavity, so it's not necessarily optimized for clearance, but that wasn't an issue for me. As my build is an R5 3400G, 32GB of RAM, and an NVMe drive on an x4 card, it really doesn't need anything bigger than 300W (it doesn't even need that, really). The build quality of the PSU appears to be up to the level I expect from Silverstone, despite being a lower-priced product. The adapter plate is grey/silver, so you may want to hit it with some spray paint, if you care about aesthetics. The 24 and 8-pin mobo power cables are long enough for whatever small case you may be using.
In operation, the PSU can be completely silent. There was a sash-type notice on the power supply, warning the user that the PSU fan doesn't always spin, as it's temperature controlled. Even when it's spinning, the fan isn't that loud. It is a little weird for the sound floor to change that much for a running computer, though. In operation, I didn't have any stability problems, and I had solid 3.3, 5, and 12v line voltages.
If you know you're going to stay within a 300w power budget, this power supply is a great choice. It's solid and quiet. The only thing that's kind of janky is the color of the adapter plate, which I'm guessing most purchasers won't use, anyway. Recommended.

Por si fuera poco, incluye un adaptador para montarla en un gabinete ATX y todos los conectores necesarios para placas ATX. (incluidos 2x4 de 12V para el CPU).
Espero no tener que actualizar esta reseña con malas noticias pero, por ahora, estoy gratamente sorprendido.
