Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
Hey, I'm from serbia, and i have xfx 8600gt but not the same model as shown on top of the thread. It's this one
Well you can guess, a cap has blown and i need to replace it. It's 1500uF/6.3V
now, i've found some capacitors here in locale shop, but i need help to chose the right one. The capacitor is ELKO 1500uF/6.3V radial, electrolyte. Is it the rigt one?
By the way sorry for the bad image it's from internet because i'm currently unable to photograph the card since it's not in my possession until Friday.Comment

Read the link. - Different card but same problem.
You need to replace all the FZ caps.
ELKO do not sound like low ESR caps.
The replacements:
- need the same or more Ripple
- need the same or less ESR.
See FZ data sheet in the link.

Hi! I have same problem. My XFX 8600GT caps blown (the FZ ones).
I can't get Rubicon on my market (Farnell). Do you recommend any other?Last edited by gsedej; 08-01-2011, 01:33 AM.Comment

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
Rubicon are fake Rubycon.
If you spell the name right searches might go better.
[You won't find MBZ or MCZ though. Both are out of production.]
Any with:
the same or less ESR,
the same or more Ripple,
the same or more voltage,
the same uF,
that physically fit will do.
FZ specs are all over the place so in 'good brands' sometimes you need high grades and sometimes middle grades to match specs.
I have no idea what Farnell stocks.
I also have no idea where 'my area' is, so suggestions as to alternate parts sources might not be useful.
Badcaps.net ships to most countries.
There's a member here named 'Big Pope' that sells Samxon out of Hong Kong.

PCBONEZ, thanks for reply!
Sorry about Rubycon, it was typo. I am new to this :>
I can also get it from Mouser.
Could you recommend me replacements for
-FZ78 1500 6.3V
-FZ77 1000 6.3V
-FZ76 470 16V
Thanks!Comment

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
FZ 470/16V - is diameter 8mm or 10mm?
FZ 1500/6.3V 10x12.5mm 1800/.022
- Nichicon HM 1500/6.3v 10x16mm 2000/.018
- Panasonic FM 1500/6.3v 10x20mm 2180/.019 [Height might be a problem.]
FZ 1000/6.3V 8x12mm 1150/.036
- Nichicon HM 1000/6.3v 8x11.5mm 1140/.030
[Ripple is close enough as the FZ specs are probably a reach.]

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
Thanks again for reply and suggestions.
470 and 1000 sizes are 8mm x 12mm
I found on mouser those:
16V 470
http://eu.mouser.com/Search/ProductD...cpWB%2fA%3d%3d
6.3V 1000
http://eu.mouser.com/ProductDetail/N...DjgUpG%2fmA%3d
6.3V 1500
http://eu.mouser.com/ProductDetail/N...hgib7x5Q%3d%3d
You think it would be OK?Comment

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
That works.
That works.
Not a great choice.
- That one is only 12.5mm long and that makes Ripple/ESR 1540/.025
- The FZ you are replacing has Ripple/ESR at 1800/.022
ESR should be same or less - Ripple should be the same or more.
There is no such thing as too high a Ripple rating.
The Ripple Rating does not affect the circuit, just gives the max Ripple the cap can handle without overheating internally.
-
Too high an ESR reduces how much Ripple [noise] gets removed. [Bad]
In some cases too low an ESR can cause problems because the ESR works with other components.
Lower ESR is better but don't go nuts with that idea or you may find one of those 'some cases'.
I would use either:
- The 10x16mm HM [PN: UHM0J152MPD3] which has Ripple/ESR at 2000/.018.
- The 10x12.5mm HZ [PN: UHN0J152MPD] which has Ripple/ESR at 2280/.012.
[I would choose the HM unless height is a big problem. I'm thinkin it's not if the 15mm you picked for the 1000uF works. They are only 1mm different.]

BTW:
You aren't doing bad at all for a first time doing this.
Lining up all the planets [specs] at the same time takes a bit of practice.

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
Hello, i have the same problem. I already had this problem once and i took the card to repairs and replaced the bad capacitor. Now few months later i have the same problem. They charger me 20 Dollars for it ..... I m not going to pay that money again and i do not have money to replace the card. I m asking to identify the marked capacitor on the picture please. It was replaced at the repairs. I need to know the original capacitor specs cause i think they didnt replace it with correct capacitor. If anyone could tell me the specs i would appreciate it.
Thanks in advance

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
All 9 caps need replaced. - FZ are serious junk.
They used a 470uF so presumably the old cap was a 470uF FZ.
There are only two 470uF FZ sizes and both are 16v.
You just need to figure out which diameter it was and you should be able to tell that by looking at the PCB 'circles' and the other caps.
The spec sheet for FZ is posted a few posts up this page.

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
Are they polymer caps ? Cause they look like so. And also is there any way i can see or calculate the ESR and Ripple somehow ? Cause on some web pages its not shown.
Regards
Edit:
I found these available at my country. Are they suitable ?
1000uF 6.3V http://www.serigo.ee/product_info.ph...ducts_id=47645
1500uF 6.3V http://www.serigo.ee/product_info.ph...ducts_id=70505
470uF 16V http://www.serigo.ee/product_info.ph...ucts_id=107729
Or maybe this ? Polymer - http://www.serigo.ee/product_info.ph...8f2ead0b72b80f

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
No, FZ are not polymers.
Sleeves are just a way to mark caps.
Both Polymer and Electrolytic can be marked either by direct printing or with sleeves.
It's up to the manufacturer.
There is no way to calculate the specs.
You usually have to find the manufacturers site to see the specs.
If the manufacturer isn't 'big enough' to have a site then rest assured their caps are junk.
I'll look at your list in the morning. It's late.

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
Unknown series. I can't say yes or no without knowing the series.
Good brand but not Low ESR. I wouldn't recommend them.
Good brand. ESR should be low enough.
... But that series has 470uF/16v in both 8mm and 10mm and that ad doesn't tell you which it is.

Re: Blown (FZ78 1500 6.3v) on XFX 8600 GT. What to buy?
I m from Estonia, near finland. There isnt really many offers. I checked the mouser but shipping itself costs 20Euros already and thats insane for few capacitors.
Btw, is it okay to have polymer capacitors instead ?
Another thing i noticed that the capacitor that is replaced is 470uF but 35V instead of 16. Can it cause any problems.
And can the FAN speed be related to blown capacitors as it wont go over 30% even tho the temps was almost 90 Degrees Celsius.

Hi folks,
I'm new to this forum. So my trusty 17-year-old LG 47" LCD recently died. As I was booting it up, I heard a hum followed by a loud bang, sounds of pieces flying around, and loss of power to the unit. Inspecting the PSU, I saw two obvious problems: a blown thermistor (bang + flung pieces) and a visibly bulging main cap. Inspecting as many components as I could with my Fluke MM, I diagnosed that the following components on the "hot side" of the board were also bad: one of the 2 main MOSFETs, main 8A fuse, small cap (25V 47uF) connected to main caps, and a blown... -
HP Modelnumber: 14-dh0061nb​
This laptop had a shorted cap on a Vcore section. After replacement is works again. But there is still a battery issue.
The battery is HT03XL and with the built-in component test from HP, in the Power section, I get an error: Logic State: Calibration required (20), Charge state: Blown Fuse (42)
I have another same battery, also with error: Logic State: Very Weak (70), Charge state: Blown Fuse (42)
And a third battery TF03XL (looks identical) with error: Logic State: OK (0), Charge state: Blown Fuse (42)
