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.

I don’t understand why flex is used instead of SFF PSUs when they weigh about the same but the SFF is actually smaller.

I used it to power an internal drive chasis outside of a Lenovo m720q running as a backup server with a wire jumper running between the atx-24 pins so that it would power on without being plugged into a motherboard. It was rock solid. Eventually I built a server and this fit the chasis for that so it is still running 24x7. I’ve had no issues so far.

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.

I built a low profile media center using an Apevia power supply... I even modified the fan so it doesn't burst into flames in a day... but no luck. After about 600 hours, that PSU tanked so I reached a little deeper in my pocket and picked this up. I've owned about a dozen Silverstone power supplies in my life. Only 1 failed after a transient event which the company replaced without hassle (and they even gave me a new cable set to boot which was a nice bonus). All the other ones are still running (the oldest is a 2012 circa 750 ATX Gold)... The only other company I know that can match that is PC Power and Cooling (RIP).

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.

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.

Some people claim the fan was loud but I haven’t had an issue with the fan at all. It could be that I’m not pulling anywhere near the 350watts but I will say it is a lot quieter then the super micro psu in a 1u server. I think at most I am pulling 80 watts since it’s basically a NAS but in a living area so quietness was number one which is why I went with this. Maybe some people got ones with bad fans or are pulling the full 350 watts but I did pickup a noctua fan because of what people were saying but I ended up not using it. YMMV.
