Small, light weight and quiet fan  Time owned: 0 to 3 months
I've owned this power supply for 8 weeks now. I purchased it to use when I'm away but have been so impressed with it compared to my Palstar PS-30M I've made it may main power supply in the shack.

I've load tested it, running it with a constant 15 amp load for 5 hours without any issues.

I'm somewhat confused by those who have posted here stating that the fan noise is high. I'm either lucky and have one that is very quiet or the other reviewers must have very sensitive hearing. Compared to the Palstar the fan is near silent. Yes it runs all the time but it's not an issue. I've had to reduce the speed of the fan on the palstar because it is so loud, and even now it still drives me nuts.

In summary, a great little PSU.

Went bang, then gave off a pong.  Time owned: 0 to 3 months
I thought, what a good idea to get a small lightweight and portable PSU for general use and also easy to carry if portable etc.

Good job I gave it a good testing before using it in anger. I suppose it lasted all of half hour. There was a bang then an awful pong.

Only advantage was that it was easy to put back in the box due to its small and lightweight construction.

Not a bad little PSU - but that fan!  Time owned: 0 to 3 months
This is a neat little PSU, with Voltage and Current meters, It was able to drive my Icom IC756 Pro3 to 100W with no problems.

However .... within 10s of switching on the radio on RX the fan cut in at full blast and stayed on. It is very loud and obtrusive and you can't really live with it to be honest.

I did some checks and the IC756 draws about 1.5A on receive. The exhaust temperature (air out of the fan) was a fairly constant 32 degrees C, so not excessive.

An email to the distributor confirmed that this is normal behaviour. It is good value, but there are quieter models on the market.

Cheap !  Time owned: 0 to 3 months
Annoying !
Runs mt IC746 fine but how loud is the fan ! So loud I have to put the supply on the floor and it still annoys me. Having the meters was nice for a budget supply, I thought. What's the point if it's on the floor and you can't see 'em !

works ok for me  Time owned: 0 to 3 months
I purchased one of these units prior to seeing the adverse comments on here so I was a bit apprehensive for a while. However, when it arrived, using it with my FT897D into a dummy load I tested it on SSB ( 100W full power"whistle test" for about 1hr to get the fan to cut in) as well as AM & FM with no trips or on/off problems so not sure why so many bad reports on here as it powers my rig & works as it should, so either I've been lucky or others just plain unlucky.Check out the BHI price on E-bay. 73 Dick g4djc

Good value for money  Time owned: 0 to 3 months
I recently purchased a Watson Power-Mite from a local amateur and it's one of the best SMPS units I've owned. I've never had any problems where the unit trips out and it's very stable, even when running 100W output on my Yaesu FT-450. The usual RFI or 'hash' is produced on 80m, but it's much better than other 'switch mode' units that I've used. It's certainly good value for money on the second hand market and ideal for portable work.

Rubbish  Time owned: 0 to 3 months
I have had this model of PSU before to power an IC-703 and had no problems with it. However, I have just bought an FT920 and thought I would try with this PSU again (new purchase). On switch on, the PSU tripped out and despite numerous resets, I could not get it to power the rig. The radio shop sent me a replacement and exactly the same thing happened!! I have returned them and have bought a Samlec 1223 instead - no problems with this PSU
