"POWER PC" ML915 350W power supply

Re: "POWER PC" ML915 350W power supply

How does bloating affect primaries? Can you measure a lack of uF flowing through it? I ask because I ordered a brand-new primary cap from a well-known "good-brand" cap manufacturer that came bloated.

I emailed them, but any effort on my behalf to get them to admit to their lack of QC was met with their disclaim.

So you're saying the KDC primaries fail in droves

I can confirm seeing a KDC primary with its guts spewing out the bottom.

Re: "POWER PC" ML915 350W power supply

Scenic: I would use bigger than 680uF for a 550W PSU - probably 1000uF or 1200uF.

Tell that to Antec, not me :p
Then again, it's an active PFC PSU (even though it's botch-jobbed with a piggyback PCB.. Antec style), so it probably doesn't need THAT much bulk capacitance on the primary (?)
2x 680uF in series = 340uF compared to your 500-600uF suggestion. And this is an old unit too (not much beef on 12V yet)

Why did they make a no-PFC design so recently??? Tacking on the PFC is just...wrong. Although, with their use of those Fuhjyyu craps, this is merely adding insult to fatality.

"recently" is a bit of an overstatement..
Searching for that PSU on google, the first result is a post on tomshardware from may 2004 lol

It's just a Truepower .. not Truepower New or Truepower 2.0, so it's pretty damn ancient.

I know. I was using the word "recent" in a relative sense.

Re: "POWER PC" ML915 350W power supply

I did.. in an Antec of couse

out of a Truepower 550 EPS

one was noticeably lighter than the other and the innards were flopping around loosely..

Me too. None can blow Fuhjyyu better than Antec.

Antec still makes PSUs with Teapo and Capxon.

Re: "POWER PC" ML915 350W power supply

When I see them after only 3 years or so, they are VERY bloated, looking like they are about to explode. In one case, not only was there a major bulge from the top, but the rubber seal was so bulged out that it had pushed the cap off the PCB.

I can confirm seeing a KDC primary with its guts spewing out the bottom.

I might make the $20 investment into buying two new primary caps on my next paycheck if the KDC caps are THAT bad. If I do that, I might also spend a couple dollars more and get three each of 47uf, 10uf, and 4.7uf 50V Panasonic FC caps to make this PSU have purely all Japanese capacitors, like my Delta Power 450W.

I've seen Ltec in an Antec Basiq BP430 430W PSU, however I think Antec's pretty bright these days to have all Japanese capacitors in their High Current Gamer and High Current Pro lines of power supplies.

Yes, but not in entry level. http://www.hardwaresecrets.com/artic...ly-Review/1487

I did not mention Antec's other product lines having good caps, just their higher end HCG and HCP lines. I do know that Antec still has Taiwanese caps in their other power supplies.

$20!? No way. Don't pay more than $5~ a piece.

Yes... I just came across several HCG-400 PSUs. I shined my flashlight in one of them and saw Rubycons on the secondary (One other I checked had UCC)!!!

By unit price alone the primary caps I want are just under $5 a piece, however with the $8 CAD flat rate shipping that Digikey.ca charges for orders under $200, and the high sales tax of the Canadian province I live in (15%) the total comes to just over $19 if I were to order two new primary caps.

Re: "POWER PC" ML915 350W power supply

It's probably worth the price paid, considering how appallingly unreliable those KDCs are.

To be honest, I'm not too worried about Teapos in PSUs as long as they're at least halfway decently ventilated, but CapXon? No way..
Every single flaky or dead FSP based PSU I come across has bad Capxon KM/KF all over the place
The batch of dead be-quiet! E5 series PSUs I got recently all had a single non-bulging Teapo surrounded by Capxons puking their guts out lol

edit: the be-quiet! E5 series as well as many other BQ's are FSP OEM, but custom made (not quite like any regular FSP series)

Buy new old stock ones. You can get them shipped free from China.

All the FSPs around here get bulging teapo and good capxon

Re: "POWER PC" ML915 350W power supply

I can confirm that in psus that used both Teapo and Fuhjyuu caps the Teapos survived.

Same with psus that use Teapo and Capxon...

JunFu caps used in identical psus with ones that used Capxon KM/KF didn't bulge, while the Capxons always did...

CapXon KM is General Purpose, so it's zero surprise that they failed.

If you're talking about the 2200uF 6.3V 8mm KFs, maybe it's just that those caps are especially bad. For replacing them:

• Nichicon HM or Panasonic FJ are overkill, but have a 2200uF 6.3V 8x20mm.
• Or you can attempt to squeeze in a typical 2200uF 6.3V 10mm (not easy).

Re: "POWER PC" ML915 350W power supply

I forgot to mention that the psu maker used either Capxon KM or JunFu WG (10mm 3300uF 16V for 12V and 10V for 3.3 and 5V). Just out of curiosity, is Junfu WG a lower esr series compared to Capxon KM?

Yes it is. Jun Fu WG is a low ESR series with identical specifications to Fuhjyyu TM . CapXon KM is general purpose as mentioned above.
