Flex ATX Power Supply 400W Fully Modular PSU Full Voltage 90V-264V Small ITX Computer Supplies for POS AIO Gaming Server Desktop

I needed a compact power supply for a custom 3D printed enclosure with 12 3.5" hard drives, and this little 400W PSU fit perfectly. I was honestly amazed at how much power it has for its size. It easily powers all the drives, cooling fans, and even a mini-ITX motherboard that I use as a jump box. The fully modular cables help keep things tidy, and it provides plenty of power with headroom to spare. A great choice for tight spaces!

Case seems well built, and the cables seem adequate. Right after installing it in my HP S5-1214 slimline, it booted up fine and SEEMED to run normal.About 5 minutes later... the power cycling / rebooting started.This happened during a Windows Update so obviously I assumed the reboot was due to the updates. It failed the update and corrupted the disk.UEFI would bring up the Windows boot load manager, but it wouldn't recognize my C: as a bootable Windows install anymore. I restored the drive from a backup, and it seemed to be fixed... and then the reboots happened again, and again.The power supply wasn't holding voltage. Finally, I realized what was going on and pulled this fancy 500W PSU back out and installed the old 350W supply that's been running for years without problems other than a noisy fan. Everything is fine.I ordered a Noctua 40mmx40mm-20mm fan to fix the noisy one in my old PSU, though the GPU upgrade will have to wait until I can find the disposable cash, and patience, to try this again with an American or Japanese made PSU.In typical communist fashion, the Quality Control on this unit is terrible.I read the reviews and saw mixed results, so it's possible I just received a factory lemon... but if you don't have time or technical background to diagnose a faulty PSU, pass on this company and spend the money on a Corsair or some other acceptable brand. :/UPDATE: I gave them a second chance, and just asked for a replacement unit. SAME PROBLEM. The voltage drops under load... which the factory 240W HP unit (204W on 12v rail) and the 350W unit I was using, had no problems with. This unit NOT ONLY can't support the draw it says it can, it ALSO seems to spike voltage to uncontrolled levels when it cycles back up. How do I know? Because my new $2000 laptop was plugged into the same wall outlet as this garbage PSU and when the tower power started power cycling, the laptop errored out, crashed, and would NOT reboot without unplugging from the shared wall outlet/circuit and hard-resetting with as long power press/hold. I managed to get the laptop up and running fine AFTER unplugging it from the shared circuit.DO NOT BUY FROM THIS COMPANY. PSU IS UNSAFE, not ONLY for your computer it's powering, but ALSO ANYTHING on the same circuit it's plugged into. I got lucky there wasn't permanent damage... you may not be so lucky. This PSU DESIGN is horrible, and the QC is obviously non-existent. Save your money... buy a MORE expensive PSU from a reputable manufacturer.

When reading some of the reviews, I was concerned about the fan noise some customers were complaining about. So, I purchased the recommended replacement fan to install. However, after receiving the power supply and connecting it to the motherboard, it is the quietest power supply I've ever installed. Everything works great and I'm very pleased with the power supply. The only problem I encountered was during installation. I had failed to verify the measurements to ensure the new power supply would fit. Fortunately, I was able to find a way to mount the new power supply. I would definitely recommend this power supply to anyone. Just make sure you check the measurements to ensure it will fit into your case.

Very compact for 600W, I loved the flexibility of the wiring but most all micro ATX MB's have the power connectors in the middle of the board and if you want to use with the Audheid K7 case, you will need an extension for the 24 Pin MB power connector.Not sure how long the fan will last and in reflection I should have purchased the extra warranty.Its long and fairly heavy, so I'm looking for a way to support the far end.

I received this 600W flex PSU and got it installed. Yay! I’m excited. I power up the PC, it boots. Hurray! I shut down the PC and all goes well. Awesome! But then it’s time to boot the PC and the power button does nothing. I unplug the power cord, wait a few seconds, plug it back in and it boots just fine. Shut it down again and I have to repeat. Well this is annoying. Not the end of the world and something I could deal with, after all, I built this 4.3L PC to move around the house easily so I’d be unplugging it every once in a while anyway.But then it got worse. I boot the PC and it gets to the login screen and the the screen goes black. Ok, I guess I wasn’t paying enough attention and it timed out, but that’s strange, it’s not responding to my mouse or keyboard. I unplug the PC with it still powered on because it wouldn’t respond to pressing the power button even after 30 seconds or so. I plug it back in and it goes to the windows failed to load screen. I click advanced, click start normally and it restarts and gets to the login screen. I type in my password and the screen goes black. Hmmm. I leave it as is and remove the side panel. The CPU fan is no longer spinning but the LED’s are still on. I unplug and plug it back in and try again. I watched the fan come to a stop as the screen went black once again. Ok. Time to verify it’s the power supply. I get a normal SFX PSU out, hook it up and the PC boots just fine. I’m in the Windows environment and run a CPU intensive benchmark. The benchmark runs for 10 minutes no problems. I shut the PC down, press the power button and it boots back up. OK. Flex PSU confirmed pretty much dead.I order a replacement. Send the old one off the same day. The next day I get the replacement and am excited to get it installed. I get it screwed into place, hook up the cables, then my mouse, keyboard and power cord. I power it on and it gets to the login screen. Woohoo! I put in my password and… black screen. I performed the whole unplug, plug back in and boot thing 5 times. Each result the same.I hooked up another PSU, power on the PC and all is well.0 for 2 now on this PSU model. I ordered both a Silverstone and an Apevia to see how those fair for me. I will update this review later based on my experience with those.*** UpdateI ordered but never ended up using the Silverstone flex PSU. It’s expensive, but the biggest issue was it isn’t modular. For a $160 PSU, I expect modular. And because it wasn’t modular, the extra cables I didn’t need kept it from fitting in the tiny case I needed it to. Because it wouldn’t fit, I never used it, just returned it.Apevia: this is where it’s at. I’ve ordered probably 30 different Apevia PSU’s over the last several years and I have had 2 DOA. That’s already better than the TF600. I’ll take 1/15 over 0/2 any day. The Apevia model I bought is modular and I’ve now bought 8 or so now. One of them is in a portable case with an i5 13600k and a 4060 Ti and it powers it with no problems. I’ve only had the 2 of 30 DOA and none have failed after installing.
