Re: Fortron Blue Storm II FSP500-60GLN

well i dont really want another one which fails in 1 year so i wont be doing rma. so i am open to investigation in the name of science.

Re: Fortron Blue Storm II FSP500-60GLN

here's something that may be of interest....
as said, you're probably looking at primary side as it was violent.

Re: Fortron Blue Storm II FSP500-60GLN

@willawake: I just saw a display unit of the Silverstobe Strider ST50F here in my locality.

It looks exactly like that Fortron unit. Same side exhaust & same exhaust near the are where the wires peak out of the unit.

The Only difference is that the ST50F comes in a black finish instead of blue.

replaced with Corsair vx550w
has matsushita primary and chemicon KY (although cant see secondary side i can see mercedes vent there too )
smells really bad of paint smell though i think it will stink out the apartment when i fire this up. 5 year warranty which is pretty cool. is the smell guaranteed for that long?????

Re: Fortron Blue Storm II FSP500-60GLN

the smell is pvc outgassing.
it will fade soon.

[willawake]

Re: Fortron Blue Storm II FSP500-60GLN

hope so
pvc is prohibited in eu though.......

sick psu....i love the black powdercoat

Re: Fortron Blue Storm II FSP500-60GLN

...only for packaging food and the like.
For all other purposes there are no much limits even in EU.

Re: Fortron Blue Storm II FSP500-60GLN

and for construction hardware like tubes and cables, i think.
IIRC that was after the Düsseldorf airport almost burned down.

Re: Fortron Blue Storm II FSP500-60GLN

Heatsink size and weight doesn't mean as much as it used to.

If a curve (graph) is drawn for heat dissipation to current passed for any device that is PN junction based the curve isn't linear. (Transistors, MOSFETS, Diodes, Diodoe Packs, ect). The heat dissipated goes up at a faster % rate than current.
-
[I looked up a Schotkey Diode Pack to pull these numbers from.]
With 18 amps passing through the Diode Pack and it dissipates 9 watts.
At 9 amps it only dissipated 3.4 watts.
-
If you use two Diode Packs in parallel to pass the original 18 amps the total heat dissipation is 6.8 watts.
- Need about 25% less heatsink devoted to that 18 amps..

Since better PSU's are using more parallel parts to reduce heat it makes sense that better PSU's will have smaller heatsinks than one would expect based on what was typical in older designs.

Some of the newer better PSU's are upping the switching frequency.
The higher frequency means smaller transformers to pass the same amount of power.

I just got an FSP Epsilon FX700-GLN (700W)
Looks very similar to the Blue Storm II FSP500-60GLN.
(I wish paint on the truck was that good!)

Re: Fortron Blue Storm II FSP500-60GLN

willawake, was this fortron constantly on?

[willawake]

Re: Fortron Blue Storm II FSP500-60GLN

yup 24/7 why?
connected to APC RS 1000

thanks for the article by the way

Re: Fortron Blue Storm II FSP500-60GLN

i'm wondering if it was working 8hrs a day (or less) would it last 3 years?
hehe...

have some more .pdfs, will put them all in new thread, as finding thsese pdfs wasn't easy at all. i saw them mentioned, and then it was all hard google work.
i'll upload them here incase my fortron eats my hdds.
<wink>

still didn't dismantle it?
come on, let's see the autopsy!

Re: Fortron Blue Storm II FSP500-60GLN

To not start a new thread, I will ask here. A guy changed the fan for 1300RPM Thermatake. After using it in more power demanging computer, he smelt something burning.

I changed the fan for one of higher airflow. Yet, when I retested and kept ir runnign for longer time, it seems that the problem is not jsut insufficient ariflow. The big input inductor next to the primary cap really is bad somehow cause it heated itself to 150 °C And it is very dark now

The question is, does it have some very specific values? Or can I just replace it with some other inductor I removed elsewhere? Not sure whether it is part of input filtration or the active PFC this time.

[goodpsusearch]

Re: Fortron Blue Storm II FSP500-60GLN

It is tbe active PFC coil and it is well known for getting too hot and burnt. I would replace the coil and hope that the low rpm fan was the cause of the disaster. I would also check the primary cap's esr and capacitance.

This is all good and well, but diodes have a negative temperature coefficient, like most semiconductors. (Excluding mosfets.)

As temperature goes up, this means the forward voltage drops. This causes one diode to carry more current than the other, causing its temperature to increase, which causes it to carry more current, which causes... thermal runaway.

This can be avoided if the resistance of the leads and PCB can effectively compensate for this and if both diodes are very closely thermally matched (i.e. tied directly to the same heatsink and ideally on either side of the sink.) Or, if the diodes are on the same die. So, you can put maybe two diode packs in parallel, but probably not many more, unless you tie resistors in series with each pack, and then your efficiency drops.

TY! Is this only the case of Fortron's GLN, or other PSU's as well? Cause I never heard of it.

Anyway, swapped for coil from my good ol' Seasonic, seems to run fien now. Will do some OCCTing

Re: Fortron Blue Storm II FSP500-60GLN

Nice, thanks. I remember I have read the thread but the repair was not finished by that time, than I did not continue. Nice work. This thing looks like it is working too.

Anway, I guess I will add at least ESR meter to my buying list, but later also capacitance meter and inductance meter. Could be of use:-D

As for this coil of mine, I think it may even be some kind of manufacturing problem. There seem to be two spots where the wires are soldered together. I believe this should not happen. Most likely due to the heat the insulation coat broke through, than the wires got connected due to the solder and than it became even worse.

Re: Fortron Blue Storm II FSP500-60GLN

I own esr micro v4 that saved me from a lot of trouble. It measures both capacitance and esr and has survived some incidents with capacitors that were not discharged completely.
