Flex 500w

I saw this power supply and could not believe the price so I immediately had to get it! I did not know what to expect, but I am so happy that I jumped at the chance to get such a great deal because this is such a very nice power supply for my pc! It is definitely 110 to 220 volts and includes the motherboard as well! It is fully modular and it seriously made wiring this to my PC such an easier task than other power supplies that I have had! After getting everything installed my PC was running super smoothly and everything is working 100% as it should! It is as described in the ad and has everything that is supposed to! This is a great bang for your buck don't miss out on this one! Got to give it 10 out of 10

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.

Finally decided to try this thing out. Put it together in a mini pc build and it seemed to work fine. System booted, didn't seem to have any issues. Played around for a while, really just to test it out and it all worked okay. Haven't really had much time after to stress test or anything like that, but at least it worked which is better than some of the other reviews I read.

This a good unit if you are using an APU or a smaller CPU, but not great if you want to use an external GPU. It just doesn't have the power to support it, even though it has an eight pin GPU connector in the box. Use this is you have no other choice. I even thought that it may have been a one off issue, so I bought a second one, when it was an Amazon Deal and that one did the same "shutdown" trick as the first one. If you want dependability, then go with a name brand, if you just want a small power supply for projects that isn't going to be taxed too much (No where near the 500 watt rating, maybe 300 watts max) then this one should work OK.

It claims 98% efficiency. I dunno about all that. I've got no way to generate the correct load to even get close. I did two things for test with the green pin shorted. First on the SATA rail I added extenders to get eight drives powered up (no data, just drives, good for jbod rack). Then with none of the modular cables attached I used the 12v and ground from the 20 pin to power a small amp with speakers. Both worked so. I'm not ready to build a new PC out of it, yet, but it will. It's nice and small, smaller than standard ATX. Use the measurements in the ad and compare to your use. There was minimal noise. If the fan was even running it was less than my background noise. At the current price of $50 it's a good value. Especially if the small size matches a mini setup that needs replacement.
