EVGA = Crap??

Re: EVGA = Crap??

Wow Piece of shit EVGA FX5500. Looked at it today and about 10 Sacon FZs....Thank you EVGA!!!!!

Re: EVGA = Crap??

So I finished recapping this board using Nichicon HN (new production).

Board works fine -BUT- the CPU fan constantly speeds up and slows down. Sounds like a wind blowing on a winter night. I configured cool n quiet and smart fan in the BIOS. Temps are 40C. Any idea how to get this to run at a constant speed?? The fan idle speed was set to 30C, I upped it to 40c but that had no effect.

FZ= lytics that look like polys
- Correct - And it seems they did it on purpose.
There are Blue marked Sacon FZ that look like UCC Poly
There are also Black marked Sacon FZ that look like Nichicon Poly.

Note: We need to say "Sacon FZ" in the future to avoid confusion.
[As opposed to just "FZ".]
- Though I haven't seen any 'in the wild', there are other brands with an FZ series

Notes to the newbies:
Both Lytics and Polys can come with or without plastic sleeves.
That is just the marking method.
Says nothing about the kind of cap they are.
.
It used to be that only Lytics had vents. [Except for Fujitsu Polys.]
That isn't true anymore.
- I'm seeing Polys with vents from several manufacturers now.
My guess is they are using one kind of can for both to reduce manufacturing costs.

FZs suck as well.

Re: EVGA = Crap??

I don't buy the implied conclusion.... Not without a LOT more details.

Poly found bad might have more to do with their environment than -what- they were.

KC works on some industrial equipment that gets a lot more abuse than a PC.
[Context: PC = PERSONAL Computer, as opposed to an industrial/commercial computer.]

A bad environment can blown anything as proven by many times over by Rubycon Lytics popping their tops in Dell SFF/USFF PCs.

- Are Rubycon lytics therefore bad/junk because they sometimes blow up in extreme environments?

That is the same cause/effect assumption/conclusion you are making about those shorted Polys.

Re: EVGA = Crap??

iirc KC said that he has seen junk polies short out....

How can they not even make polies right?

Re: EVGA = Crap??

Keep polymers. I've never heard of junky polymers, even from companies that are known to make junk.

Just curious about the ESR. Do they mean the ESR is 0.008 and 0.0014?

Re: EVGA = Crap??

Who knows, but as long as it's not reading high, it's good. You're safe to replace the Sacon FZ with Rubycon MBZ or Nichicon HM.

If you want an exact replacement, search for Sacon FZ, the datasheet has been posted inline and as an attachment many times.

Re: EVGA = Crap??

Yes, the charts say that ESR rating is expressed in milliohms, so .014 and .008
should be the correct ESR values. I wonder if 2-digit ESR meters round up?

Re: EVGA = Crap??

I found the LELON spec sheets: http://www.lelon.com.tw/index.php?fn=product&id=1.

They claim ESR 8 and Ripple 5500 for the 1500uf 2.5v 10x12.5mm.
So that impedance is theoretically 01 on my 2-digit ESR meter?

The 330uf 16v 10x12.5mm are listed as ESR=14 and Ripple = 5050.

Replace these or keep?

You didn't check the forum before you bought that did ya...

Got me! No, didn't check. I mis-measured the 470uf 16v - they are 8mm.
I have Panny FM on hand to cover those, although they are a bit taller.

I was hoping to use 6.3v 1500uf MBZ 10x12.5mm that I have on hand, but note Ripple is only 1540 vs 1800 for the FZ. I also have 1500uf 16v MBZs which are taller, but who cares.

I am dubious of the quality of the LELON solids in the VRM. Are there any spec sheets on these? Series is OCR as mentioned above. Thanks to all for
your help.

Depends on which FZ you have.
Panny FM are good for some, for others you need at least MBZ grade.

Re: EVGA = Crap??

Nichicon HM or HN from Mouser... They ship to Canada. Make sure to indicate the cheapest shipping option. Only $8, but takes around a week. Cheaper than Digikey and Newark, and in fact, the cheapest shipping of them all.

Re: EVGA = Crap??

yes he has the 470uf 13v in samxon and rubycon. his list has been much expanded...

Topcat has MBZ/GD in 8mm, which aren't spec'd well enough to replace the 10mm FZ. He carries 10mm 470uF Samxon GT, but those aren't good enough either.

The rubycon caps topcat has are MBZ, whose ripple is a bit lower rated than the FZ. However, I would just go for it anyway and assume the FZs were overkill. Many motherboards use MBZ or equivilant, (or even lower grades at times) and it works fine.

8mm MBZ is close enough to 8mm FZ, but 8mm MBZ is nowhere close to 10mm FZ.

I'm all for supporting the site whenever possible, but in this case, nothing in the store at the moment works.

Re: EVGA = Crap??

Badcaps.net doesn't carry anything that can replace the 16V 470uF FZ in 10mm. The options in the US are polymer from digikey or 10mm Nichicon HN from mouser. I'm not sure what stores will ship to Canada.

Specs for 10x12.5mm FZ:
ESR: 22 mOhms
Ripple: 1800 mA

Badcaps carries suitable replacements for all other values of FZ though. For the 8mm diameter FZ, you can use Rubycon MBZ/Samxon GC or equivalent. For the 10mm FZ, get MCZ/GC.

Re: EVGA = Crap??

nForce 4 right? nForce 4 is ok and worth fixing, unlike all the later nForces which have defective substrate engineering.

No why exactly would you BUY a board like this? Sure it has two PCIe x16 slots, but don't you know how old 939 is? Also I believe these boards are DDR, at least the A8N-E board I recapped recently was.

Besides the Sacon FZ, list the brand and series of the other caps.

It's a hobby. I like old technology. I do have newer boards, I am writing this reply on a newish AM2 board. For my purposes, which do NOT involve using a 50-inch TV as a monitor or getting max frame rates on a video game, 939 is just fine.

Markings on the LELONs are OCR and L545(M)
I see there are also three 16v 330uf LELONS of the same type.

Are LELONS crap caps too?

The shiny SACONS are SZ603 - that's all the markings on these.
