Fortron FSP300-60GLS: starts/spins/dies

[goriath]

Hi everybody,

I own this PSU, FSP 300-60GLS but is not working. As soon as I power the PSU on the fan starts but immediately stops afterwards, nothing else happens. In my experience this is a classic for a PSU.

Initially I opened the PSU and I got two brand caps; while the majority are OST there are two CrapXon as well. The very fisrt thing I noticed was a cap slightly bulged, CapXon 2200uF 6.3V. Other caps are in perfect cosmetic conditions but since the CapXon are crap, just for troubleshooting, I decided to replace both with what I had available at the moment, two KSC same capacity but 10V. Nothing changed.

Now, the question is very simple. I should keep to replace all the caps with good ones? There is any chance that this problem involves caps or is it about something else?

Thank you in advance

It could be caps. Also, if you are testing this without anything else connected, it might be because it needs a minimum load. Don't use anything you want to keep, like a good motherboard, to load it. I use lightbulbs and resistors. I do have a dual channel constant current load, but it can only do 150W per channel.

Re: Fortron FSP300-60GLS: starts/spins/dies

I always start PSUs with a minimum load like fans or FDDs, this was also the case but the PSU's fan stops immediately to spin anyway...

I think that even if others caps are apparently in good condition, maybe some of them are failing and need to be replaced anyway, or at least I hope so. But I wanted discuss the issue first to, eventually, buy new caps for nothing.

Well it's impossible to say if new caps would definitely fix it. If it doesn't work, you could always un-solder them and keep them for use in something that works.

Re: Fortron FSP300-60GLS: starts/spins/dies

replace the small ones.
and look real hard, those FSP supplies often have caps hidden inside heatshrink tubing.

Absolutely true. Those Fortron PSU need also special size caps, those very slim 8mm caps, damn...

replace the small ones.

Vey true. I found two sleeved caps, one CapXon and one OST, those closest the heatsink; cannot told what they were until I cutted the sleaves.

If I'm not wrong until now I have localized these caps:

x8 OST 1000uF - 16V RLP
x2 CapXon 2200uF - 6.3V KF
x2 OST 22uF 50V RLG
x1 tiny OST unknown capacity and voltage - RMH series - I cannot tell more since the only way to know is desolder it - it is the smallest one

What do you mean for small ones? 22uF and the unknown tiny one?

Re: Fortron FSP300-60GLS: starts/spins/dies

What do you mean for small ones? 22uF and the unknown tiny one?

Yeah, probably the 22uF, and any other 5mm or 6.3mm diameter caps. Probably in the range of 1uF to 47uF.

Re: Fortron FSP300-60GLS: starts/spins/dies

if you need 8mm then look at panasonic FK series.

Re: Fortron FSP300-60GLS: starts/spins/dies

Yeah, probably the 22uF, and any other 5mm or 6.3mm diameter caps. Probably in the range of 1uF to 47uF.

The tiny cap turned out to be 2.2uF 50V - I noticed one thing, I don't know if it is relevant but on the top of this cap there is a little sign of a bluish substance, I don't know if it is a leak or whatever; the first time I saw it I didn't give it so much importance since I thinked it was a sign of a blue marker that sometimes you find on caps. I attached a picture of it:



I started to replace this but, again, nothing changed.
Must try with the two 22uF but I have only one replacement for these in this moment.

if you need 8mm then look at panasonic FK series.

Thank you for the hint.

Re: Fortron FSP300-60GLS: starts/spins/dies

the blue is ink from a pen,
you often find caps marked by the factory for whatever reason.

Re: Fortron FSP300-60GLS: starts/spins/dies

I decided to try to replace all caps with good ones.

The caps I have to replace are:

x2 CapXon 2200uF 6.3V KF series - 8mmx25mm
x8 OST 1000uF 16V RLP series - 8mmx20mm
x2 OST 22uF 50V RLG series - 5mmx10mm
x1 OST 2.2uF 50V RMH series - 4mmx7mm

Do you have good alternatives (like nichicon, rubycon or similar...) for these?

P.S. I searched for Panasonic FK; I found FR instead...are they good as well?

[stj]

Re: Fortron FSP300-60GLS: starts/spins/dies

FR are best, but sometimes you cant get one physically small enough.

for really small values like 1uf and 2.2uf you may have to use FC series because i dont think FR come smaller than 4.7uf.
atleast not last time i looked.

[goriath]

Re: Fortron FSP300-60GLS: starts/spins/dies

OK I found from a single shop:

2.2uF from Panasonic FC series (5x11mm) <- how about FC?
22uF from Panasonic FR series (5x11mm)
1000uF from Nichicon HM series (8x20mm)
2200uF from Nichicon HM series (8x20mm)

For less than 20 euro shipped

How good is this selection?

P.S. I don't know if I can ask here (if not, don't mind) but where can I buy good caps here in europe (I live in Italy)?

Re: Fortron FSP300-60GLS: starts/spins/dies

Europe, Farnell is good.

why the nichi's ?

Re: Fortron FSP300-60GLS: starts/spins/dies

I have NCC KZH 1000/16 D8 and KZN 1500/6,3 D8 especially for these SFX units and also standard GLN. This si just GLN (Blue Storm II) in smaller package. Have a box filled with these units here, all of them have caps bloated hard. Nichicon Hm are no way for power supply.

stj: you are omitting me on purpose or why are you still pushing Farnell which is three times as expensive as me?

Re: Fortron FSP300-60GLS: starts/spins/dies

There becomes a point where buying a brand new version of this PSU (they are not £) would also be easier as defeatist as that may sound, you do not know for certain that caps are the problem with your unit.

but then you still have to recap it because the new psu's have such shity caps you cant trust them to last more than a couple of years.

i have recapped several new psu's so they can be trusted afterwards.

I selected the nichi only because they are the only 8mm caps available from the shop I found - but yeah, I think they aren't so good afterall.

Unfortunately farnell has the same problem for 2200uF capacity; they have only those HM nichicon for 8mm diameter.

Yep. Since you seem know this PSU, do you have a good cap selection for this PSU recapping?

Obviously your POV as people that tipically consider this kind of work is not worth it is absolutely legit. Well, I think that if I replace those caps with good ones I can have a better PSU for an affordable price afterall and the trouble of getting the PSU work again is something I have already considered and to which I am willing to. But you are absolutely right when you say that I don't know if the caps are the problem or not, so I must find spare replacement first to buying a good kit of caps (I'm looking in the stuff I have at home, old motherboards and similar...).

but then you still have to recap it because the new psu's have such shity caps you cant trust them to last more than a couple of years.

Indeed, what you said is what I think too.
I forgot to say that I got this PSU for free, so I'm willing to have some "fun" with it.

goriath: yep, those KZH 1000/16 and KZN 1500/6.3. I have already done one unit to check everything works. You can squeeze a 6pin PCIe in there with little drilling, that's what I've done. Needs at least a single hard drive to have some output on +5 V rail otherwise it does not handle heavy crossload well (group regulated, modern systems with SSD draw close to nothing @ +3,3/+5 V rails).
