Silverstone Technology 350 Watt Flex ATX Power Supply with Fixed Cables and 80 Plus Gold with 6Pin PCIe Connector SST-FX350-G-USA, Black（Lead-Free Paint）

This is a great PSU. It is a bit noisy if you are anal like me and others on this review page. If you'd like to void the warranty and put a quieter fan in this PSU my suggestion after trying the noctua route is to not use noctua (the fans people are recommending on this review page are not rated for this psu in terms of cooling efficiency and in my case the fan wouldn't even turn on unless I hooked it into my fan header on my motherboard even though its 12v in the psu and on the noctua fan. A more proper recommendation and expert advice would be to purchase Delta AFB0412HB 12V DC 0.16A Fan 40mm x 40mm x 15mm from ebay for 6 dollars. Be sure to check the polarity of the 2 pin/wire for this fan to ensure it matches the existing scheme/configuration. I believe its reversed but like I said, check for yourself. But Delta AFB0412HB 12V DC 0.16A Fan 40mm x 40mm x 15mm is a much better option than the Noctua. Don't waste your money on the noctua 40x10mm as not only is it too small and would require duct tape to cover the gap on the outside of the psu after its installed, its not even strong enough to push air in an efficient manner. Anyhow I wish you all good luck in your DIY this psu. For those not that are not ANAL like me, the noise is really not that bad. But I'll let you be the judge as I have tinnitus so I hear ringing in my ears anyway.

Little loud, little pricey, and I wish it was modular -- but it's important that I rate this good - because when I bought it 6 months ago, I think it had a 3.5 or 4 star review overall, and that almost wasn't good enough for me to spend the money on it. But I have stress tested it under heat, dog hair, vibration, weird power surges, poor cable management, and wiring mistakes. I'm told replacing the power supply's internal fan will help with noise, so I came back to the listing to check out the specs. Totally recommend this PSU for someone building a tiny ITX computer. Mine is powering a 1660Ti ventus xc (physically modified to fit case), MSI H510i Pro, 16gb ddr4, i5 10400f, m.2 ssd, two sata ssds, and an noctua NH-L9i. Never had trouble! And I am playing the latest games at high settings despite having a 9x13x3 computer.

There is a reason they don't show you images showing all the cables viewable and probably would not have very many returns if they set that expectation for the customer. I put this in the A09 itx 3.8L case with 7700X 105W CPU for a productivity machine... There was no way all those cables were going to fit in there so I removed all but the motherboard power cables. Tested everything out before putting in the case and fan was not loud because the system was idle. Several minutes after getting into the case this thing sounded like a server room or vacuum cleaner when it comes to noise level. I was going to replace the fan with Noctua but it was going to be a challenge and found info that expressed that it may not provide enough airflow to properly cool this Power Supply but I will research more to validate. This thing does a great job for my needs and the cables might not need to be modified if you were to go into a larger case but you really can't get much smaller than this A09.

These Silver Stone Flex PSUs are great and reliable. The only thing which for me is a fine trade off is the noise level is a little high. But it’s worth it. A lot of PSUs at this size are iffy at best. So it’s an easy recommendation.

This PSU fan is loud but it’s such an easy fix, and with these small PSUs being really hard to find, especially powder coated for aesthetics, I bought one anyways. The process for replacing the fan with a noctua one was incredibly simple, albeit it will void your warranty. Besides this caveat the new fan brought many benefits, namely the much quieter operation but also the ability to control the fan speed from the bios.

You cant hear this thing running . I purchased a replacement fan reading the other reviews.. Nope, you dont need it. You cant hear this thing running at all with the stock fan. Installed in a 1U rack mount. I did need to trim extra power leads I did not need as the cables are insane long and thick. This is a very nice power supply and I do recommend it.

Fits with the Goodisory A02 case with MSI B450i Gaming Plus AC motherboard.I was skeptical of the reviews that said it was really loud. This is my first PC build, and I thought everyone was just spoiled by expensive high-end PSU units that are near silent. I was wrong.The noise is very prominent, and near impossible to ignore if your tower is on your desk. I think its not so much the volume, but the tone/pitch. It almost sounds like a small drill.I decided to brave the fan replacement as well, while not knowing anything about it. Anyone who says here that it's easy, is being misleading. It's pretty tricky. What you want is the Noctua NF-A4x10 FLX 40x10mm 3-pin. Use the 3-pin to 2-pin connector included in the Noctua. The PSU fan cable is zip-tied to another cable, but is only one 2-pin. The fan in this unit is 15mm, so the Noctua is 5mm thinner but fits perfectly fine. I covered the gap with electrical tape.HOWEVER!!!! The red/black wires on the fans are reversed for this unit!!! It will not work out of the box!!! Once you remove your fan, check how the fan’s 2-pin plug fits into the board and look for the red/black wires. Are they the opposite on the Noctua? That means for your Noctua cable, you have to take off the plastic white part (that plugs into the board) from the red/black wires, and swap them and plug them back into it. This is not difficult, you take a needle and push the silver parts in to push the wires out. But you’ll want to find some videos on how to do it.Even still, your fan may not spin! Mine didn’t. It just twitched. I was pissed. I pushed it to get it going with a toothpick, and since then it starts spinning on its own on boot up … but I still keep an eye on it to make sure it’s spinning … which is annoying. The fan in general seems like maybe it's not getting enough power, but does seem to be doing its job.After all this, the PSU seems to work fine. But considering the fan replacement mod (that I consider necessary) and all the included hassle, I’m giving it a lower score.Hope this helps someone.EDIT:After several weeks, my replacement fan has not had a single issue. It was just that first time it didn't spin.

If you have ANY experience with computer hardware, you may know that a computer naturally isn't very loud unless it's dusty, cheap, or under a heavy work load. This power supply makes a sound that isn't exactly what I'd call "annoying", but definitely present. It's like the sound of a tower fan in your room that's kind of old; it's not annoying, but it isn't soothing like white or brown noise. Besides the noise, the cables are stiff. I haven't built into my ITX case yet, but using this PSU as a bench supply is not exactly easy. I'm going to mod a Noctua 4x10 FLX into this PSU and give an update within the month.UPDATE 9/9/20After replacing the fan, cooling seems fine (despite cfm differences in fans). There's 5 screws: 4 sides screws (one warranty screw) and 1 screw underneath a version sticker (mine included one). With the 12V FLX variant of the Noctua 4X10, I was able to replace the fan. Another thing to note is that the stock fan seems to be stuck in place with the metal fan grill plate (besides the 2 screws that keep the fan in)-- I had to break the fan to actually remove it. It's not 100% silent, but WAY WAY more tolerable and almost silent within a foot from the supply. Will update again if there's any overheating issues.UPDATE 8/28/21 (Almost a year of use)I've had no issues with overheating, shut offs of the power supply, or noise complaints within my case.UPDATE 8/18/22 (Almost two years of use)Still no problems with the modified Noctua fan and the computer that’s using it is on at least 6-10 a day. No overheating, no shut offs, no weird sounds.UPDATE 5/19/2025 (Basically 5 years of use) Currently the computer sits in the kitchen as a family PC, letting it be exposed to some smoke and oil/grease in the air. No problems yet.UPDATE 5/7/2026 A year later after sitting in the kitchen, it's being used as an at-home office computer that NEVER gets turned off. No problems or complaints from anyone using it. No random shut offs.

Es una buena fuente de poder, la verdad es de muy buena calidad aunque algo ruidosa.

Solid PSU. Fits nicely into a Watchguard M470 firewall that runs OpnSense.Do note that the fan when it kicks in is a bit louder than desired, and there are several guides on how to change out the fan.Note: Those guides will void warranty, and heed the advice given - don't use a Noctua fan, it doesn't shift enough air.

Es un poco ruidosa cuando se le demanda pero no agobiante, pero lo cierto es que varias fuentes flex atx lo son. Es mas para builds ultra compactas y en eso cumple su funcion muy bien.

Very stable power supply !I use it for power up motherboards on my test bench.

Working as described, perfect for a small form factor PC build. I like the fact that this power supply comes with sleeved cables and an external on/off button. However, the fan of the power supply can run loud, definitely not described as "slightly louder than whisper" as I can easily hear it in the background through my earbuds with foreground music.
