FSP Epsilon 1010w Worth recapping?

[mikay786]

Got this PSU with obvious bulging caps from a semi dead first gen i7 rig.

Rest of the rig appears fine, was just going to swap PSU's but now contemplating just recapping the FSP unit as only looks like a handful of caps and the PSU isn't blowing fuses or owt, its just pulsating at the minute.

Motherboard lights up and goes off constantly, so reckon with a recap should be good.

I know they are not top tier PSUs but pretty decent. So worth the effort and cost of a few bucks for caps?

FSP are worthy of a recap.

Panasonic FR series do the job?

Re: FSP Epsilon 1010w Worth recapping?

all i bother using.
unless they are too big to fit - then FK series are reduced diameter.

yupp, fsp is one of the few companies that dont bullshit on their power ratings. imagine that! a company that is actually honest!! if they say it'll give u 1010w, u will get 1010w out of the unit!

Re: FSP Epsilon 1010w Worth recapping?

Best might be to check the specs on the original caps and buy ones with very similar ESR and ripple.
Otherwise you risk having oscillations in the PSU.
(Not saying the FR's wont work, just that you should check how close they are to the current caps).

Re: FSP Epsilon 1010w Worth recapping?

Horrible layout, caps are literally crammed in there, some badly squashed and at weird angles. Not impressed

4 x 470uf 16v - 6mm / 6.3mm (CapXon GF)
2200uf 16v - 10mm (CapXon LZ)
2 x 2200uf 6.3v - 8mm (CapXon KF)
4 x 1000uf 16v - 8mm (CapXon KF)
100uf 25v - 5mm (CapXon KM)
22uf 50v - 5mm (Teapo SEK)
47uf 25v - 5mm (Teapo SEK)
2.2uf 50v - 4mm (Teapo S5)

Re: FSP Epsilon 1010w Worth recapping?

You forgot to add, some really non-standard can sizes / values, especially that group of 6.3x20mm(?) caps right on the edge of the board

I've got two of these that i got almost for free a few years ago. If memory serves, one kept blowing PFC fets, and the other i hadn't / haven't even gotten around to opening up

you need the series as well as brand!

Re: FSP Epsilon 1010w Worth recapping?



cant seem to fiund the correct size for some of these caps, for example the data sheet for GF series above. 16v table only seem to have 8x16 and 10x12.5 for the 470uf caps?

Whilst the caps are 6.3mm x 20mm

[mikay786]

Re: FSP Epsilon 1010w Worth recapping?



Could it mean some of these caps are fake capxon if the data sheet doesn't have the same size?

For example]

2200uf 6.3v KF Series - 8mm x 25mm



On data sheet the above caps only come in 10mm?

custom ordered parts.

Re: FSP Epsilon 1010w Worth recapping?

As i was saying...

I believe i juuuust managed to shoehorn some 8mm dia ones into that first one i had started working on, but i'd have to dig it out to confirm. Either way, even those stock custom 6.3mm ones were a real tight fit, crammed in-between all those wires.

Re: FSP Epsilon 1010w Worth recapping?

So im going to have to go by the nearest size.

so for the

2 x 2200uf 6.3v - 8mm (CapXon KF) = 1470 ripple and 0.095 impedance

with

2 x 2200uf 6.3v - 10mm (Pansonic FC) = 1440 ripple and 0.045 impedance

https://cdn.badcaps-static.com/pdfs/...bd3de58c23.pdf

Is that close enough if it fits size wise? First time bothering with ripple / impedence so just want to make sure im on the right track.

Yea its a pain. Is it alright reuse the old caps that are measuring ok?

only 3 caps are dead which are the 2200uf 6.3v and 16v ones so could just replace them?

[Khron]

Re: FSP Epsilon 1010w Worth recapping?

You could, but then you'd also be damn near certain that (some of) the other C(r)apXons *will* die on you sooner or later. My vote's on "sooner"

Nichicom PM or PJ series are closer matches on impedance, PM being the closer. Having less than half the impedance of the original could cause stability problems.

Re: FSP Epsilon 1010w Worth recapping?

Replaced what caps I could within reason, and reused the 470uf ones as physically nothing else will fit. Not worth trying to get something similar as the value of the psu is not worth the expense and effort of trying to obtain them.

Anyhow put back together and seems to be working on my psu tester. Aside from measuring dc outputs on the 12v, 7v and 5v rails and thing else I can measure before putting back in PC to make sure it's safe?

[Khron]

Re: FSP Epsilon 1010w Worth recapping?

By "7v rail" i assume you mean "3.3v" rail, right?
