    • Solid performer.
The unit runs very warm under load. It does NOT have a cooling fan, just the heat sink. I use it to power a telescope and accessories drawing about 3.5 Amps. The green light is quite bright, but can be covered up with a bit of electrical tape. The power jacks are the correct spacing for standard dual banana plugs. It's new to me so no data on how well it lasts, but it seems pretty solid. ... show more

I like how this power supply provides a steady supply of power to my base station. This makes no noise and I have zero complaints about it.

    • Just what I needed to run my diesel heater
I needed to run an D/C powered diesel heater using A/C. Worked great with no problems. The only issue was that the connector screws were touchy, but they worked okish.

They work better then the ones I was using wich was 300 MG and these being 300,000,000 MG, they work better then my ones I was using I normally take a gummy at night and this one I can tell is going to work good at night as well. I will 100% recommend these gummies. I use them for stress and anxiety and they really do work with the combination of my meds, they work good
    • Great Value- Long Life
I have been using the same PYRAMID PS12KX 10 Amp power supply since 1995. Used extensively for Ham radio with heavy, duty cycles, used continually for nearly 1 year 24x7 for APRS with no issues. Just purchased a new PS14KX 12 Amp to used for additional radio service. For me, it been an incredible product that I have relied on for over 25 years of heavy usage.. Buying another for me was a no brainer. ... show more

    • Do NOT Believe the Description of this Power Supply
After speaking with several veteran Amateur Radio operators about power supplies, I realized that there were a few general consensuses about power supplies for use with amateur radio transceivers. #1 is to buy one that is larger than you need initially. It’s likely you will have more radios in the future than you do now. A close second on recommended features is to buy a power supply that has a built-in cooling fan. With those words of wisdom in mind I began searching on Amazon, and soon found this product, Universal Compact Bench Power Supply - 12 Amp Linear Regulated Home Lab Benchtop AC-to-DC 12V Converter w/ 13.8 Volt DC 115V AC 270 Watt Power Input, Screw Type Terminals, Cooling Fan- Pyramid PS14KX.5 . It appeared that this unit fit the criteria of being larger than I needed right now, AND has a cooling fan. You will notice the words. “COOLING FAN” right there is the title of this power supply. Also, in the details section there is the paragraph that states: ”BUILT-IN COOLING FAN: The power converter features a cabinet heatsink and a built-in cooling fan to prevent the device from overheating. Constant amperage is 12A and surge is 14A w/ power output of 13.8V DC and 115V AC 60Hz 270W power input” Sure looks like this is the one I need. However, as I read more information and checked the reviews, I became concerned. There were reviews, some older and others fairly recent, that indicated this unit does NOT have a cooling fan. There were also reviews that discussed overheating, and shortened lifespan. This caused me to be more concerned that this really DID have an internal cooling fan. It was at that time that I looked at the “questions” section. Here is found this response, FROM THE MANUFACTURER, that answers this question: Are you 100% sure this unit has a cooling fan? Answer: Hi, yes it has a cooling fan. You may check other details of the unit by visiting our website pyleaudio.com. Type the model number on the search box PS14KX for more details. Thank you. By Pyle S. Manufacturer on November 26, 2019 I felt reassured that there WAS an internal cooling fan. However, as the question and answer were almost 3 years old, I felt a look at Pyle’s current website was a good idea. To my relief, this EXACT model is listed as having a built-in cooling fan. This information was current as of the day I ordered the power supply as it is the day I write this review. Feeling confident that this power supply was the one to purchase, I ordered. Amazon delivered FAST! Upon opening the sealed box, I found the power supply, well packaged, and a user’s manual, which also stated that this unit has a cooling fan. Only upon actually examining the power supply did I learn that this unit DOES NOT HAVE a build-in, (or any other kind of) cooling fan. Let me repeat… THIS POWER SUPPLY DOES NOT HAVE ANY KIND OF COOLING FAN. At first, I was disappointed that there was SO MUCH information indicating this unit has a cooling fan. I really wanted this to be what it said it was. The price was fair, and the Pyramid brand was mentioned by several folks I spoke with as a reliable brand. Disappointment soon turned to feelings of anger. Why was there so much information that was wrong. NOT just in one line of the advertising, but in a direct question, and answer FROM THE MANUFACTURER with the absolutely WRONG answer. Not wishing to take a chance and disregard recommendations from folks who have been in the amateur radio hobby for quite a while, it seemed to me that returning the item was my only course of action. In this AMAZON was again TERRIFIC. The cost of the unit, and the cost of the extended warranty were quickly refunded to my credit card. It’s really frustrating that all the companies that sell products on Amazon aren’t a customer oriented as is Amazon. I do hope the manufacturer becomes aware of this misinformation, and corrects their advertising and owner’s manual; OR… maybe they will begin building this unit WITH a build-in cooling fan. If they do, I hope to find one. With the exception of the needed cooing fan, this appeared to be a well-build power supply. ... show more

    • Chunky, Very Quite/Clean, Linear Power Supply
This is a big, heavy linear power supply. Very quite (less that 5mv ripple) and power is stable under load. Linear power supplies are a necessity for radio and audio where switching power supplies generate much high frequency noise. And NO, there is no fan. It's not needed. Quite your whining.
