Re: XBOX One Power Brick Repair

:o: Wow, thanks for the exceptionally detailed explanation!

I inquired as to whether the power transfer design was flyback or not (which it was, I should have observed, based on the lack of an...

Re: XBOX One Power Brick Repair

Do the Xbox 360 and Xbox One power bricks use flyback or push-pull topology on the secondary side? I ask because japlytic posted this (...

Re: Power supply build quality pictorial. part 2

Sorry, I wasnít addressing you and I didnít word that well. I just meant that it would behoove the reader to note however often later Delta units would cook CrapXons and LTECs by way of thermally...

Re: Power supply build quality pictorial. part 2

That DPS-300KB-1A is designed very well EXCEPT for the standard recovery diode on the primary side (and you thought the toasty output diode on the +5VSB rail was a shoddy design in later units...)....

Re: Asus A7V8X hdd issue

So this may sound like a ludicrous question, but I’m guessing you did measure every single capacitor, including the PSU capacitors, out of circuit, to determine whether or not they measured to spec?...

Re: Panasonic FC series - leaking? quality gone?

I don’t want to denounce Panasonic (as a brand) too hastily if my last post ever came across as such (Panasonic FK, for instance, seems to be fine). It’s a possibility those Panasonic FPs (and the...

Re: Panasonic FC series - leaking? quality gone?

The FP series is the miniaturized FC series with a much higher ripple current rating. It was released over two years ago. Both series are supposed to be certified for automotive applications. I’d...

Re: Panasonic FC series - leaking? quality gone?

I enclosed the datasheet for the HFE series. HFG/HFQ was the recommended replacement at the time, after which the FC series became the modern equivalent. It seems all HF* series use the quaternary...

Re: Panasonic FC series - leaking? quality gone?

LXJ too? Yikes. Never seen one leak before but I wouldn’t put it past them. I know they were also used in old proprietary Newton Power 200W PSUs from 20+ year old Dells. FC should not use the...

Re: Panasonic FC series - leaking? quality gone?

They are both non-aqueous. I donít know if both series employ the same organic solvent (gamma-Butyrolactone is a common solvent) and solution. The only way to know that is to ask Nichicon, and all...

Re: Panasonic FC series - leaking? quality gone?

I recollect you saying the case size was 5x11 for those 100ĶF 16V Nichicon PM capacitors, though. According to the datasheet, it should be 6.3x11. So I wonder if they truly were genuine. :why:...

Re: Very old Sanyo OS-CONs. Safe to use?

Sorry, got carried away and forgot to mention that part. Use them at your own risk (with caution). Although, despite being Japanese made solid capacitors, something makes me uneasy about using said...

Re: Very old Sanyo OS-CONs. Safe to use?

I wouldnít deem myself an expert either, however interested I am in the topic.

But those Sanyo OS-CON capacitors (technically not polymers in the strictly technical sense of the term; they use a...

Re: best cheap/free scores 1.1

Also forgot to mention Nichicon HM/HN/HZ post-2005 capacitors, although it’s yet to be seen if they will make it 15+ years without unexplainable failure.

All according to their respective...

Re: BFG Tech BFGR550WGSPSU [LW6550SE Rev. K] Ė recapping & modding

I think the sleeve bearing fan failed faster because itís mounted horizontally so the lubricant evaporated at a quicker rate (and the fan may have been noisier as well whilst mounted in this...

Re: Killed my Asus A7V266-E? Need advice

They actually appear to be Nichicon HD (1500ĶF 6.3V, they appear to match the case size in the datasheet as well going by the photos provided). The fifth image in the third post depicts part of the...

Re: Old stock capacitors

Teapo SM is crap, too. No longer in production IIRC, but Iíve seen too many motherboards with every one popped or bad. Iíve seen them fail just sitting as well. Other than that, they (Teapo) are...

Re: Old stock capacitors

Re: Why do people use TEAPO / YAGEO / G-LUXON?

Sorry, I should have specified. I wrote that a long time ago but I was referencing the capacitance rating. It seems no CapXon series is exempt from trouble regarding any voltage load very close to...

Re: Fake Rubycons?

If the whole board is full of swollen capacitors it could have come out of a poorly ventilated and/or cooled case, or maybe certain FETs or coils on the board, neighboring said capacitors, dissipated...

Re: Panasonic FC series - leaking? quality gone?

Sorry, it was just a suggestion, wasn’t trying to dictate the general consensus. Rubycon MCZ and MFZ have issues pertaining to heat failures but they are not known to fail just sitting unused. MBZ...

Re: Panasonic FC series - leaking? quality gone?

Rubycon YXF is another excellent series which has proven itself worthy in terms of long-term reliability, although itís an ethylene glycol based series IIRC but with a very good endurance rating.

Re: Power supply build quality pictorial. part 2

The cooling in BTX based systems seems to be problematic. Actually, many of the failed KZGs and KZJs (and -some- MCZs) Iíve seen have come from BTX cases. I still see them failing when the...
