FSP Group Mini ITX Solution/Flex ATX 80 Plus Platinum 500W Pmbus V1.2 High Efficiency Power Supply (FSP500-50FSPT)

This review is for the FSP 500W 80+ Platinum without 6-Pin GPU PCI-E connector. Overall: I am using a 5USD 12V Molex to PCI-E 6-Pin adapter to use this power supply with a GPU. This power supply is awesome. I bought the Athena Power 500W silver before from Newegg and was very disappointed. The Athena is extremly noisy even in idle and geta very hot under load. The FSP instead is extremely silent in Windows 10 idle (Ryzen 2600, GTX 1060 6GB) and only revs up under load. Even under load though the FAN is definitely hearable but is a nice hum with a medium tone frequency. The FSP gets also very warm (not hot) under load. My guess with touching it with my hands is 40 Celsius) but cools down right away after load and the fan will also revv back down to very silent. My main rig is watercooled with a 750W Seasonic Platinum power supply which does not get warm at all. So my main build ia nearly dead silent. Even with that reference I am positively pleased how silent super small builds with mid range components combined with this FSP Flex ATX power supply can be. Would not have been possible a couple yeara back. PROS: Silent Efficient Sturdy casing A lot of power for such a small form factor Much better than the Athena Power 500W silver Cons Very long cables and in general too many SATA and Molex connectors -- an issue when you want to pack it into a small case and have to stuff the cables somewhere No PCI-E output

I've only built a few PCs in the past, and this PSU taught me a very, very important lesson. tl;dr the 500W model will need an adapter to support a GPU and I would not recommend trying to replace the fan, despite it technically being possible. Can the 500W model support a GPU? Not out of the box, no. You will need to get a Molex to PCIe adapter. Double check your GPU for what kind of pin requirements you may have (6-pin, 8-pin, etc). It does come with 8-pin cables, but those are specifically for the CPU. Do not, I repeat, DO NOT try plugging those into your GPU. The Q&A portion of this product suggests that the PSU can support a GPU and that there are 8-pin PCIe cables. That may be true for lower-wattage models, but not the 500W model. I checked the Q&A before assembly and went ahead assuming all 8-pins were created equal. In my ignorance, I forced the 8-pin CPU cables to my GPU (GTX 970) and fried it. You'd think the resistance from the differently-shaped ports would have stopped me, but considering this was a SFFPC build I had gotten used to pushing past a bit of resistance. Big mistake. Get an adapter for a PCIe cable and this PSU should work out just fine for you. Don't be a dummy like me. Can the fan be replaced? Probably, but not easily. The default fan is super loud upon boot, but eventually quiets down to nearly silent. I planned on replacing the fan, but after cracking this thing open noticed that it is absolutely packed on the inside. It would take small, deft fingers to handle the job, and even then I'm a bit skeptical as to what kind of impact replacing the fan would have. My recommendation would be to spend a little extra to get a higher wattage PSU than you need so you will be less likely to put it under a load that will turn on the fan. ----------------------------- FINAL BUILD Case: K39 Mini ITX Mobo: ASUS Prime A320I-K Stor: WD_Black SN750 500GB RAM : Corsair Vengeance LPX 1x16GB CPU : Ryzen 3 3200G, Noctua NH-L9a-AM4 fan GPU : GTX 1060 6GB (single-fan) PSU : FSP Group Flex ATX 80+ Platinum 500W Extra: StarTech.com LP4 to 6-pin PCIE Adapter

I'm not a big fan of the Flex-ATX form factor, but it DOES allow for some tiny builds. For me, that was an AMD 3700X and a 1660 Super on an x470 board; all inside of an SGPC K39 from Aliexpress which allows me to fit an entire gaming setup in my backpack. When I picked up my case, I had also purchased a random Chinese branded Flex-ATX unit which had a lot of good reviews... It worked well enough, but that was until I decided to do some heavy gaming at a LAN party, where the unit failed one me. So far, this FSP unit has not let me down. The price is a bit high for a 500W power supply, even a Platinum rated one, in terms of normal ATX units. That's kind of the thing though, you're going to pay more for Flex-ATX, and going the little extra for a nice FSP unit as compared to something from Aliexpress is honestly worth it. If you're reading this nonsense and considering this unit for your build, I'd say just go for it! For 500W Platinum in THIS form factor, and especially the brand, the price is really not that bad. You DO have to use a power adapter for the GPU though. I've got a double molex to GPU power connector, and that seems to be working well. This isn't a huge negative, but would be annoying to sit down and build and realize you don't have a power connector for your video card. Easy ~$8 fix on Amazon if you don't want to be bothered rigging one up yourself. And now... The fan noise. The fan IS quite loud at full tilt. When you first power up it will sound like a dang vacuum cleaner for a few seconds as it ramps down to a normal idle speed, which is nearly silent. Under light loads like a bunch of Chrome tabs, Discord, Coding, Image Editing, whatever non-gaming things you're typically up to; this thing is mostly silent in my experience. IT DOES get quite noisy under some more demanding gaming loads. However, my old Flex-ATX unit (the Aliexpress one that fried) was even louder with its stock fan as compared to this unit, and supposedly had the same wattage output, so the noise level on this thing isn't actually all that bad for Flex-ATX. The Noctua fan mod does help, my old one DID go very silent after I did the noctua fan swap that people recommend. I've heard of people doing the same thing to this unit, though I wonder if the airflow with the thinner fan wasn't the reason for my other unit failing, so I've yet to make the swap on this one. I would imagine you'd get that similar near silent performance, though the stock fan -is- better than other Flex-ATX units from what I've seen, and the fan noise is less of an issue altogether if you game with a headset. 10/10 power supply performance all things considered. If you're going Flex-ATX, you should DEFINITELY consider this unit.

PSU was pretty good for my Mini ITX build with a 8700k + 1080ti. Not giving it 5 stars, cause i asked if it came with a pci-e connector and was told "yes" but it didnt. My PSU only makes a lot of noise when the PC is booting, other than that its pretty quiet. I'm really happy with this product.

I have been building a mini itx system for a few weeks now and after testing many flex ATX PSU's and getting this one that died completely after launching a gpu stress test has made me completely give up on the Flex ATX form factor.

If you're using this on an actual PC, be sure to pick up a connector conversion to power the GPU card. The start-up fan volume is kind of nutty, but only really lasts through POST - I've never heard it turn on otherwise.

After one year of ownership I can safely say this is not what you're looking for. Yes, it is a power supply and it seems to be a pretty reliable one. The problem is that the fans they use in these are awful. They are loud and they constantly change speed so it becomes very annoying to have your computer in the same room as you when it's on. Even under a low load the fans will spin up for some reason. I recently swapped this one out for the ENP 7660B VK 600W Flex ATX Power Supply sold on Velkase's website. Oh boy, what a difference. Night and day. Even under a heavy gaming load the fan on the ENP 7660B is extremely quiet. Do yourself a favor and skip this one. Go for the ENP 7660B VK 600W instead.

fits perfect, works great.
