OK  Time owned: more than 12 months
Got it free with my radio and it works ok. Actually it works excellent but the cable is too short. Made my own extension to solve that problem otherwise a good decent power supply.

NOT PERFECT!  Time owned: 0 to 3 months
I'm an ICOM MAN 100% but the PS-125 was NOT very well designed.The cord that connects with the radio is too SHORT & the fan is too LOUD.Would be nice if it also allowed some way of connecting orher gear to the supply.Had two of these that came with my 756 PROII & 746 PRO & sold both after testing too make sure they worked.I'll keep my ASTRON RS-70M & BE HAPPY!If you purchased one they are way "OVER PRICED"!

JUNK!  Time owned: 3 to 6 months
I received the PS-125 "free" with the ProIII. A screeching cooling fan prompted me to write this. That just started. When operating normally in the receive mode the fan cylcles about every 45-60 seconds. It comes on for any transmission. It was loud and annoying even before the screeching started. In contrast my Alinco DM-330MV which I have used for five years almost never turns the fan on even when transmitting; and when it does it is very quiet. I guess that is why they have to give away the PS-125 because nobody who knows anything about the PS-125 would voluntarily pay for one.

Some Problems  Time owned: more than 12 months
I am on my second one since buying my Icom 746 (non-Pro model). The one that originally came with my radio ("free") failed after 12 months. I liked the matched look, did not find the fan noise overbearing and detected no hash on the bands so I bought another offered by a ham on eham. This one has operated flawlessly for 7 years. I give it a "2" due to the failure of the first one. 12 months and out was not acceptable.

There's a REASON they give it to you  Time owned: 0 to 3 months
This switcher p/s is NOT made by ICOM - it's made FOR them by an outside entity. If they work, they work great - if they fail, just toss it, as it's not worth fixing.

The output is NOT fused (there is a 10a fuse, but if the surge supressor goes, it "saves" the fuse - typical Murphy Syndrome.

In case yours does fry the fat little black surge supressor (ZNR-1 on the schematic.. but it's NOT on the parts list), here's the ICOM part-number and component type:

p/n 6910016470 (ERZV14D621) $4.61 each

Buy yourself an Astron instead - it's not as black & pretty, but you'll be happier.

Works fine  Time owned: 0 to 3 months
Mine works as it should. The fan is audible but not near as loud as i was fearing from reading some of the other reviews. My computer's fan and amp fan is about the same big deal at all. The PS-125 looks pretty good right next to the PROIII. As others have mentioned, the power plug that goes to the radio is very short so it really needs to be near the rig. Ive checked for hash and have not detected any on the bands from this supply. These are still "free" from most retailers when you buy a 746PRO so you can snag one at a pretty low price from fellow hams who just bout the 746PRO who have no need for the supply. Nice compact size too.

Good Power Supply  Time owned: more than 12 months
I own two of these. One suddenly died after about 4 years. A switching supply must do 4 things. It must come on, it must continue to run, it must regulate and it must shut down if there is a problem. These four rules helped me to troubleshoot the unit. It turned out that it had a bad D26, a 15 volt zener. After replacing the diode, the unit fired right up. So it is back in operation. It's too bad that it doesn't have a volt/current meter. Indicators have a language of their own. They tell you what is going on at a glance. The fan is noisy but will only stay on for about 3-4 minutes. There is a sensor under the transformer that toggles an OP amp that turns the fan off/on. So even when it is just powering the receiver, the fan will cycle as it saturates the ferrite core of the transformer. It can't be helped. It is the nature of the beast. I also wish the power cord was longer. I believe they make it short to cut down RF hash. All in all though a decent power supply.

Good Match to IC-746PRO  Time owned: 3 to 6 months
My PS-125 was included with my IC-746PRO. Two months to the day after I got it, it failed. Sent to Icom Service in Bellevue, WA. It seems IC11, an op-amp, had failed. Icom Service repaired it under warranty and shipped it back to me packed better than I had shipped it to them.

I didn't see any other reviewers noting this problem, so perhaps mine was isolated. I've had no noticeable problems with RF hash or fan noise.

I agree with other reviewers that the short DC cable limits the PS to being placed to the right of the transceiver.

Note that the new PS-126 that's designed for the IC-7600 is probably the same basic supply with just a 4-pin power connector on the DC cable.

What's the BEEF?  Time owned: more than 12 months
I received the PS-125 free when I purchased my Icom IC-756 Pro III. Currently, I'm using a Kenwood PS-53 PS for the Pro III. The Kenwood PS-53 is a great linear PS. Recently, I made a trip and took the PS-125 with me to operate fixed mobile as it's definitely more compact than the Kenwood power supply. I've had the PS-125 for three years Ė never taking it out of the box. From what I've read on, many hams feel it is a "dog" Ė it creates hash and has a noisy fan, so I was quite dubious about its performance.

Well, to my chagrin the PS-125 does not create ANY hash that I can detect, and the fan noise ISNíT an issue! Yes, one can hear the fan run if you put your ear next to it. If youíre listening to a normal conversation on your rig you wonít hear the fan run. Itís actually very quiet!

If there is one item I would change it would be the connecting cable between the PS and the transceiver. The cable goes directly into the back of the PS-125. It would be nice if it had screw terminals like the Kenwood so one could add small devices that also require 12v to operate; like my RF Power/SWR meter.

Otherwise this is a fine piece of equipment. Small, compact, a quiet fan, and no hash whatsoever. FREE can be a good thing!
