Works great with my 3D printer
Works great, got it as a replacement for my Delta 3D Printer, was supper easy to wire it up and get it running. would highly recommend this power supply. is there was one thing i would have to say negative about the PS is that it did not come with instructions, might be handy for someone who does not know how to use it or is a first time user...that is the ONLY thing i could find wrong with it...still give it a 5 star rating!!!!

Just perfect.
Very good. Inexpensive. Brought my 3d printer back to life. Easy install. I also bought a spare for the next time.

Arrived earlier than expected
My PSU arrived earlier than expected, well packaged and ready to set up. Redrex3D's attention to detail never ceases to amaze me and their great customer service is a plus. I look forward to hooking it up to my 3D printer and get printing. Most definitely will upload a video once it's up and running. Keep up the great work Redrex3D

Decent unit
Not quite as beefy as I thought it would be, but running a water pump and a furnace on it. If both run at the same time, you can hear the pump run slow.

Packaged Well
The unit was packaged well. It works well and is labeled well for connections.

Seems OK, a little information:
I bought the 12v 20a supply.I was looking at the photos and I was a bit disturbed when I read the +12v and -12v labels. For reference, that's a thing, some power supplies are actually +12v/-12v and I just need a plain 12v supply.After looking closer at the actual stampings on the metal case, it says V+ and V- which I'm going to take as 12v and 0v.So you get a fail for confusing labeling although I think I have it figured out. I'm giving you two stars for ease of install for that.The screw terminals are #8 size which is helpful information if you are ordering spade terminals for your wires. #10 won't fit in the terminal block.I'm still waiting on a crimper so I haven't tried it out yet but I switched it to 110v mode (I hope) and I'll try it out as soon as I can make up cables.I'm expecting it to work, it looks fine and I don't expect to pull more than 15 amps but it's cheap and the build quality seems in line with the price. I'm giving it 4 stars for quality of materials.That averages to 3 stars. Fix the labels in your picture and mention the terminal strip size and this could go up to 4 stars.Some of the reviews state that these can make a high pitched noise when the output is powering a device that is doing PWM switching like an RGB LED controller. I hope that is not what mine does because I'm going to install it under a stage so I can't have a noticeable amount of noise (which is why I bought a fanless power supply). Hopefully they have solved those types of issue and I'll be able to get good use out of it.If this thing whines, it's a 1.5 star product.
