Silverstone Technology 450W SFX Form Factor 80 Plus Bronze Power Supply (ST45SF-V3)

I chose this for my compact Silverstone NAS which requires a smaller SFX supply, and it was a good decision. A priority for me is a quiet supply and this one delivers by using a load controlled fan that hasn't spun at all on my system yet. Admittedly, its a new build and I've only done some computationally light work so far but since this system will be used primarily as a HTPC, I don't think it's going to present any electrical of consequence most of the time so I don't expect the fan to spin much. This supply has some nice features as well such as a PCIe cable for video cards (not all SFX supplies include this) plus an ATX adapter plate for use in larger cases. Another small, but nice benefit are the thumb screws in addition the to normal PS mount screws that can be used to secure side panels on most cases. As you might expect in a moderately sized supply like this it doesn't have a ton of molex or SATA connectors but it should be enough for the smaller systems this type of supply would be typically used with.

I first heard about this small compact PSU when I called Silverstone to ask about their Milo 6 case. I initially told the tech I wanted to use a super-tiny Pico Power Supply for quiet operation and if they had a cover plate for the PSU hole. Mind you, I already had the silent Titan low profile cooler to replace the Intel stock cooler, but my cheap PSU from a ravaged Xion case was disappointing. They suggested I buy their silent Tek 300w SFX PSU. The payoff was superb! The fan inside the PSU does not turn on unless there is a heat build up. Even when the fan does goes on, you cannot hear it unless you are 12 inches away. Do not be put off by the price of this unit... it's worth every penny.. as that every other SFX sized PSU I have used has been NOISY and low quality. Reminder: this is an SFX PSU, not a standard ATX size.

I'll be honest... I really had no intention of buying a SilverStone Technology 300W SFX Form Factor 80 Plus Bronze Power Supply with +12V Single Rail, Active PFC (ST30SF). The thing is that I was putting together my first mini-ITX build since the Via Eden days. While I wanted a small system, I specifically bought a Cooler Master Elite 110 RC-110-KKN2 so I could use a standard size PSU. The problem was that the CPU placement on the motherboard, combined with the height of the Ryzen 5 3400G's OEM Wraith Spire cooler, and the PSU placement in the case resulted in a pretty small gap between the CPU fan and the PSU. Maybe it would have been fine, but I really just didn't like the idea of half of my heatsink not being able to efficiently shed heat. So, I decided to swap out the OEM cooling unit with a SilverStone Technology RL-KR01. That solved my clearance issue, but it was WAY louder than the stock unit, which didn't really work for me. After a little digging, I decided to get the SilverStone Technology ST30SF, and use the included adapter plate. Theoretically, that would let me go back to the stock cooler. 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.

Great and compact SFX PSU. Use it in my Lian Li mini ITX build which is pretty limited in space. This unit replaced a regular ATX PSU. What a difference! Apart from being compact, the build quality is excellent, all cables braided and (quite important for mini ITX) not too long, so easier to manage inside the case. Worked flawlessly out of the box. I debated whether to get this or the (cheaper) FSP 400W unit. What presuaded me to get the Silverstone was bigger fan and the braided cables. Recommended.

I bought a small form factor case for a media stream machine (Raidmax ITX Computer Case with Power Supply Case ITX0907BP) that came with a 300W power supply from RaidMax. I needed a more efficient psu but was very concerned about sizes. I couldn't tell if I needed a FlexATX or SFX ATX. This, however, was the right supply both in power and in size. It fits perfectly and the cables are nice and netted for protection in my small case. All cables were long enough to reach their destinations. Super super quiet!!

Multiple combination Wireless-AC /Bluetooth cards work fine alone, but once a GTX-1050 ti is added to the system, the cards start having issues with resolving internet connectivity in windows 10. Its odd that I have to blame the PSU, but after swapping out the PSU with alternatives, the problem goes away. I have even used a comparable 300W tfx psu and the issue is resolved. I have to think the cards are being starved for power using this PSU and the delivery isnt quite 300w

I needed a miniATX power supply for my lab computer to replace one that injected electrical noise into all the lab instruments plugged into this machine. This power supply made a HUGE difference and really cleaned up my problem. This would be an excellent power supply for a media center computer that has to have clean audio and video signals. Fan is very quiet. Build quality looks excellent. Power connectors are nicely spaced on the cables. Cables are covered with nylon netting to keep them neat.

Fits perfectly and gives all the power I need to run my Mini-ITX build (Silverstone ML07), and does so silently!

Absolutely fantastic SFX power supply. Runs super quiet and the modular cables are a dream

Elegí esta fuente para mi ensamble mini ITX , una buena opción aunque el cableado no sea Slim ni modular pude hacer buena gestión de cables . El.producto llegó mucho antes y en excelente estado

Bastante eficiente, no me ha fallado desde que lo instale en mi computadora, silenciosa y sin problemas de energía alguno.

Silent, Excellent build
