and a list of known junk power supplies

Re: and a list of known junk power supplies

what about the names weve all been conditioned to trust in the PC building community? Antec, Enermax, PC power and cooling...those are the only few i know that i would buy. i have an antec, i want a pc power and cooling, and ive heard good things about enermax.

Nuff said bout Antec... The other brands you list are good brands, but pretty much no brand use good capacitors all of the time... None of the affordable anyway...

Alas, that is very true. One sees generally good PSUs that contain whole forests of Fuhhjyu, just as one sees PC Power and Cooling sell a PSU for $500 which is packed stiff with Teapo, etc.

Then again, the 600W Delta I had was 100% Chemicon... and so was that Seasonic you took pictures of. That Supermicro/Liteon I posted is also part-Chemicon, part-Taicon (which may, or may not be, equivalent to Nichicon).

Enermax units usually have those JP-cetur, which I haven't often seen fail.

Antec and PC P&C don't make their own units. In Antec's case, Channel Well makes the lion's share of them with the Neo HE's being Seasonic (and full of Teapo caps), and PC Power and Cooling uses Seasonic for the Silencers and Win-Tact for everything else.

In terms of reliability, Win-Tact is one of the best out there despite a seemingly heavy reliance on Teapo caps. Channel Well units are very well designed, but full of Fuhjyyu caps that love to fail early when Antec cuts corners on cooling in order to make them silent. Seasonic is between the two - not as reliable as Win-Tact, but better caps and reliability than Channel Well. Not to mention quieter running.

Not sure about Enermax, it's been rumoured they don't make their own either, but I've never found out who does if that is the case.

thats the one

Re: and a list of known junk power supplies

any questions?

That's no doubt made by Leadman (same as Powmax and Diablotek) but that must be either one of the units from one of their cases or something really, really old. Because if you go to MGE's website and look at power supplies you don't see anything even remotely like that. And if I go to ASI's website and pull up all of their MGE's, the ones I can buy are either Wintech or Seventeam models.

Re: and a list of known junk power supplies

wow...seasonic puts up some good numbers for their price range. almost all of their PSUs are like up to 80% eff. and it sounds like they use reasonably decent caps too. anyone know how tight the voltage variation is on the seasonic stuff usually? my antec has like 3% and i know PCP&C usually touts a 1% voltage variation.

[Oklahoma Wolf]

Re: and a list of known junk power supplies

Not sure about Seasonic, but PC P&C's 1% numbers are pretty much marketing - Win-Tact rates their units at 5%.

[Per Hansson]

Re: and a list of known junk power supplies

Well, Seasonic seem to regulate the voltages quite well, according to my mobo the 12v have not went up and down more than

Re: and a list of known junk power supplies

@OKW: Enermax are made by Topower or Channel Well.

[Oklahoma Wolf]

Re: and a list of known junk power supplies

Actually, I doubt that... Channel Well and Topower both wind their own transformers (often having "CWT" or "TOP" nomenclature stamped on them), while Enermax gets them from Rong Chuyan (sp?). Also, the Pce-tur caps are nothing like the Fuhjyyus and Teapos CWT and Topower uses.

If anything, I think they're Superflower/TTGI/Fore Point/Fortrex. Same caps, and very similar internals.

[Chris1992]

Re: and a list of known junk power supplies

Hmm. I remember reading somewhere that enermax was Channel Well and Topower. In that same article, I remember that TTGI/Superflower was also Topower.

[Oklahoma Wolf]

Re: and a list of known junk power supplies

TTGI/Superflower has never been Topower to my knowledge... I saw a Dan's Data review claiming the connection once between Enermax, Topower, and CWT; but there's just too much evidence against it for me to accept that as fact.

The companies I know to be using Topower for sure are Globalwin, BeQuiet, Epower/Tagan, Vantec, A+GBP, Athena, OCZ, Scythe, and 2themax.

On the contrary, I'm pretty sure the comma's supposed to be a comma... although you can always translate to a point if that makes it easier to understand.

I agree - in any case I've never seen any existing CWT or Topower-made models that resemble an Enermax to any striking degree.

I have an open Enermax EG465AX-VE(G) unit in front of me at this very moment, and while its internals don't betray any "maker" other than Enermax in any obvious way, a few things are notable:

1. The PCBs in the unit are marked with UL code E171647, which, on searching, corresponds to "PANYU BIG CANYON CORP", in China. Its listing, however, only refers to the company as a maker of PCBs.

2. The two transformers seated between the inverter and switcher sinks are clearly marked RONG CHYUAN. They have their own website, http://www.transandcoil.com.tw , but again, they only appear to make transformers and coils.

3. Essentially every electrolytic cap in the unit is marked JP-cetur or JP-cetul. It looks like these two series are almost "pathognomonic" (it's a pompous word, but it makes the point ) for Enermax PSUs - are they Jen Pan/JPcon, or something else?

4. This unit uses a single 300uF, 400v Hitachi HP3 input smoother cap, although this is common to several other PSU designs.

... So one can identify several manufacturers for the individual components, but no overall PSU-designer other than UL E134014 - Enermax Corp. Can we assume that they are therefore designed and assembled by Enermax themselves?

Re: and a list of known junk power supplies

It's possible they're making their own, and are contracting the PCB's and transformers out so they don't have to put as much of them together.

Re: and a list of known junk power supplies

I have been totally sold on PC Power & Cooling products ever since I started using them.

PC Power & Cooling does the same thing though as over 90% of all companies do....they get there PSU manufactured by another company....then they literally take it apart so to speak and add or imporve upon the basic chassis.
Thus you get a top notch 100% rock solid PSU!!
I asked my friend whose a tech for PC Power & Cooling his words were interesting.
He said I cannot divulge to you what we would call " trade secrets".
Yet for having the PSU made by another companie and then taking that PSU and adding and improving upon what they get thats pretty remarkable that they have not had as many pitfalls as other companys have had...ie..major CPA issues.


actually PC Power & Cooling numbers are right on. You would be hard pressed to find a more honest company when it comes to listing there Specifications!

For that matter you would be hard pressed to find a bad review of a PC Power & Cooling product.
