AL-QURAISH 5V 70A 350WATT DC Switched SMPS Power Supply. (5V-70A Rainproof)

Nice product and good working

The product works good with steady current.Only draw back is the fan noise.If you want to use this in a quite environment then the loud fan would be heard. If using outdoors or for a stage then it can be ignored.Good product ✌️

I was very sceptical while ordering this item, due to the number of choices available on Amazon, but this turned out to be a perfect purchase. However, I am very satisfied and extremely happy with this item. I was delivered very quickly and arrived before the delivery date and worked like a charm.I am also quite happy with the seller because he even contacted me a week after the purchase, to check if the item is as per expectation and it is working.Full stars for the item as well as the buyer

Faulty item.!!!It doesn’t provide 5V as output as promised. Tested it with multimeter. The output is maximum going to only 3.82V not above that with minimum going to even 2.8V. So the output is also fluctuating between 2.7-3.82V. Also the LED indicator bulb constantly blinks with a beep kind of sound.

I found this power supply batter than other brand's 5V 70 A power supply because other brands which I tested were suitable for not more than 40 A. How ever I thoroughly tested this power supply. At 50 A continuous load after 30 minutes temperature of rectifier diodes was about 125 deg. C and transformer was 105 deg.C . After fitting an extra 4 inch fan it was possible to go upto 58Amp.and temperature of Diodes were 83 degrees.C and of transformer was 64 deg.C only, after 30 minutes of continuous use. Output voltage starts dropping after58 Amp. Overall it is good power supply. I have ordered one more Pc. of it.

Do test voltages with a proper Multimeter before using on your project.Works fine. Using this to power a 110 WS2812B ARGB led strip at full brightness.
