Re: Tagan TG480-U01 480W ATX PSU
R34 in my board is burnt.
But I found over internet, a photo from a similar Topower.
Can you upload a photo from yours?...

Re: Corsair HX850w blown internal fuse?
You can try to check bridge rectifier soldered to the board.
If wrong measures, then check it unsoldered.

Re: PSU worth replacing caps?
New capacitors perhaps need a little glue to hold them up to the plate and do not vibrate.
The point is that any glue is not suitable for components, it may affect chemically to the plate.
I planned to use [B][U]hot glue[/U][/B] but only if it is suitable for this use.
If someone could tell me if I can use this glue, I would appreciate it.
Thanks

Re: Tagan TG480-U01 480W ATX PSU
I think it is clear that aluminum is used for price / dissipation.
And you can maximize their effectiveness using very many fins (or sheets).
Copper is much more expensive and heavier (just look how heavy bunch of external cables)
The funny thing is how simple sinks without fins such as FSP 400w.
It is also true is that the fins take up space and leaves less for components.
Add more ventilation and there is no problem. (yes, more noise)
I do not know, but I imagine that passive psus have...Leave a comment:

Re: Tagan TG480-U01 480W ATX PSU
I guess so
Ok, when I open the case, [B]I will search and check them (better still with the references you have given me, D41 and D42 IIRC)[/B]
Through the fan grill I can see one diode, as in this photo.
I find this thread where you ask about a 500w FSP from a guy who changed the fan for 1300RPM Thermatake.

Re: Tagan TG480-U01 480W ATX PSU
Yes, I can fit a 30mm wide cap (the same size as actual OST cap).
I had read in a web, maybe here, that [B]if you[U] increase uf[/U] also increase mA in other components because more energy every Hz, so they could suffer[/B]. [U]It's only a caution[/U].
Of course I can buy a bigger cap, but my doubt if then I also must replace diodes, or MOSFET, or .....
There's a proverb in my country that literally says: "walk or not walk, big horse" (the bigger the better)

Re: Tagan TG480-U01 480W ATX PSU
Well, then I will replace the semi-broken primary cap and replace the secondary for security.
The primary cap is 270uf 400v.
[B]Should I replace it with same capacitance or choose a 330uf 400v like similar FSP psu that I have seen?[/B] I read there's some tolerance to capacity changes but also read that other components will suffer because more current.
[B]The primary cap is a OST serie SPS 270uf 400VDC 85ºC 30x35mm(DxH) Ripple(120Hz 85ºC)=1.70[/B]

Re: Tagan TG480-U01 480W ATX PSU
Yes, I've read that Rubycon manufactures excellent high voltage caps, and that I must to avoid those sold on eBay.
I understand that the primary cap has signs of extreme heat, and other component has been the cause of that problem.
So you told me to check the bridge rectifier, and after desoldered it I think it is OK , but you suspect that if I change the capacitor the problem will appear again, no?
I can upload all the photos you and other future people will need.

Re: Tagan TG480-U01 480W ATX PSU
I assume you mean the primary capacitor FSP psu.
As user [B]stj [/B]has suggested, I check the mains rectifier and it seems ok.
The reason could be overvoltage, but also had four adapters plugged and at the same time and no one broke .
It's curious, when I opened the source , a [B]small insect[/B] came out.
This psu is working out of a computer case, it gets so dirty

Re: Tagan TG480-U01 480W ATX PSU
I'll look at the characteristics of the other capacitors (fortunately in this FSP psu are few).
[B]This thread is about Tagan TG480-U01, and I have one broken.[/B]
When I took and opened, I thought: "Wow, it's heavier than the FSP and (for me) very well built. It seems semi-passive!! "
I had read some people say that Topower not be in the highest level psu's, but I think is enough.

Re: Tagan TG480-U01 480W ATX PSU
Thanks for your advice.
Of course, I want to replace the primary cap, and because you recommend me also replace ALL caps.
They're not bloated and now I'm checking them using a digital multimeter:

This psu is a FSP one, but I also have a Tagan 480w to replace all the caps (Fuhjyyu) except may be primary ones (Panasonic).

Re: Tagan TG480-U01 480W ATX PSU
Well, I'm stupid
I was using in the multimeter the continuity scale(200R) but not the diode scale (2KR).
I desoldered the rectifier.
If the pins are like this - ac1 ac2 + , and the multimeter cables are Red(R) and Black(B), the measures are:
-(R) ac1(B) 0.55
-(R) ac2(B) 0.55
-(R) +(B) 1.241
+(B) ac2(R) 0.544
+(B) ac1(R) 0.544
+(R) -(B) infinite
ac1(R) ac2(B) infinite
ac1(B) ac2(R) infinite
Other combinations, also infinite.

Re: Tagan TG480-U01 480W ATX PSU
Checked diode function. (no desoldered, checked in circuit)
You're right about the bridge rectifier.
No diode between +pin/ACpin and NO diode between -pin/ACpin (check in both senses)
Only continuity between -pin and the screw
How is it possible this psu can works now??
Then I must replace the primary cap and the bridge rectifier.
Do I replace the same rectifier or do you recommend me an equivalent/similar??
Thanks...Leave a comment:
