It has only one for me read the post above. I got 350uH after I put tape on outside of the core. The primary coil is 99% as it was I just removed a small wire which was making short. It can drop from 750 to 350 because of small gaps in the core after glue?

The original also has a gap. I have one more power supply unit, more powerful, I will take measurements. But 350uH is not enough anyway

But there is no gap in core after i tape it all parts are in contact as it was before. Hmmm I should not open it at all I think that if I applied DC on primary coil the short may disappeared but now it is too late.

It's impossible.

It was a very small wire 0.1mm in short. But this does not matter. Why only 350uh if is not good? Because I break the core and now the small gaps can reduce so much the inductance?? Grrr. I can't find oval core to replace it :(. If anyone with same psu could measure inductance :)
. This it will work? https://www.tme.eu/ro/details/etd39-3c9 ... erroxcube/ ?

1500uH primary coil and 200uH external L

Wow alot. So 350uH no way to work? For me external coil is 50uH.
A schematic grr to see the real value of this coil will be good :(.
So breaking the core made it so low even if is in good position after glue.



Edit: seams my lmeter measure is 20% less than real so external coil has aprox 60uH so it is like 62uH you measured. And for primary coil I have aprox 420uH stil low :(.

Seams I need to buy another core :( etd39. I read an article that breaking ferrite and glue it back reduce inductance by 30-50% :(. Sad.

From my pictures with core there seams to be a gap no? But if you see first picture it has a small area of contact. So it is with gap after all or not?

If I add ferrite dust in the middle where is the a partial gap I can have like 700uH. Any chance to make it work? What do you think RsM

Thermaltake said it is 140uH :) no way

Ok since I was unable to find the real value I added ferite powder in the middle gap until I had 750-800uH I restored the transformer and solder it in place.
Now I have all voltages OK with no load and no switching noise or something.
Any advice how to test load?
thanks

12V lamp from auto or galogen from electric store, hand-made coil from NiCr -
here or here

I tested 30secs with 55w 12v bulb and seams ok. Do I need to test more power? Or more time?

It is not a load. minimum is 150W-400W

I just received a info from Thermaltake forum that value should be 450uH hmmm i had 420 and core had some gap so maybe it is true. if core already has gap small spaces due to glue don't influence much the inductance

Any things to check when put load on it? Temperature signals etc?

Ok i just put it my pc :) and run a video benchmark for few minutes with no problem
I will let it like this. If has problems i will revert to 450uh as Thermaltake said. Thank you all for your support

Need to test more power and more time with eg resistive load made by parallel connecting high watt low resistance resistors depend of load for each voltage channel corresponded with specifications. All main channels must be loaded at the same time.
