I was worried because I heard elsewhere that ‘this power makes the sound of an airplane taking off,’ but it’s not that bad. The fan is small and doesn’t have a zero-fan function, so you can hear the fan noise, but considering the size of the fan, it’s an acceptable level.

Received on the expected date. Correct packaging, but the inner box was damaged, although the contents inside were undamaged.
600w Flex power supply. It works perfectly for my project alongside a BC-250 board to make a Steam Machine.

The power supply (550w variant gold 80 plus) is a surprisingly competent little piece of kit, very minor amount of coil whine which can only be heard if your really close to it and in a quiet environments which is beyond acceptable, the fan is probably the lowest quality part of it but not to the extent where id say to not buy this it works fine. In my use case its perfect

It arrived well packaged and the test results show that it works well. However, the cable was not clearly marked with the letters “CPU” and “SATA Power,” so I had to look at the shape to find it.
I’m going to use it on the server, and I hope it works well without any issues.

I bought a product from another company that used less than half the power consumption but made a lot of noise and was a real pain, but this one has solved all those issues. The packaging is meticulous and it’s a really great product.

Currently powering a powerful cpu + gpu combo, which is impressive coming from such a small form factor. Will be daily driving this, so i’ll look out for stability and durability.
One major complaint has to be the fan: it’s *very* loud.

A nice Flex ATX power supply, weighing 500g, much lighter than an SFX that weighs twice as much, convenient for the little space it takes up, great that it’s fully modular. Of course, the fan is a bit noisier because it’s small and at high speeds you can hear it a bit, I would say it’s almost the same noise as a gaming laptop, so it’s tolerable.
Congratulations to Metalfish for the product and the low price.
I hope it lasts a very long time. 😁

good source.
Just one thing, the cables are quite thick, different from the 500W version. It might be challenging to fit them through a small ITX case (mine was very small, I don’t want to have to open that case in the next few years because of this), but other than that, it’s perfect.

Works well, very good manufacturing quality, lightweight, very compact Flex ATX power supply. Now, the 3V and 5V voltages are quite accurate, 12V is a bit weak; I have 11.9V under Linux with a Core 2 Quad 2.8Ghz 90W, GT1030. Overall, very satisfied so far that everything is working without any problems and without any particular noise.

The unit arrived safely intact as it was well packed and sealed in shrink wrap plastic. The shipping bag tore open and allowed water to enter soaking the contents, but the psu stayed dry! I have not yet tested the psu awaiting dram for a new server chassis build. But the 1u flex-atx size is compatible and standard, and fits well. The modular design of cables is a nice feature. There are not a lot of connections for hdds, so be prepared to buy adapters/extensions for any nas. I will follow up on this review of its performance and noise characteristics. So far, so good.
The shipment was held up by uni last leg courier service. I took almost 1month to arrive.

Power supply quite quiet contrary to some comments, I think they have made improvements on the fan. The SATA/molex cable needs revision, the molex is positioned before the SATA, which prevents cutting the cable to save space in mini ITX cases, so I had to shorten and solder the SATA cable by removing the molex.

A good flex source, it is heavier than the sfx version of the same brand. It heats up slightly when the CPU and GPU are stressed, just becoming a little warm.
Looking at it from above without deeper tests, it seems to be an excellent source, since in mini ITX setups the components are mostly very limited in energy consumption.
In some reviews they said it was noisy but my unit is completely silent.
I need to conduct more tests, but the first impression is very good.

A very nice upgraded for our 3.8l mini pc , barely managed to fit it in the tiny pc case. This thing is powerful and quiet , a great replacement for the hot 350w psu with a 100 wires coming out of it. The install now looks clean , its cooler too , most importantly much quieter
