Re: Accent 600W Modular Power Supply

It a CWT [Channel Well Technology] built OEM unit.
Same OEM that built all the bad [Fuhjyyu capped] units for Antec.
-
Probably do okay with good caps in it.
I can't tell what caps are in it.
I'm guessing the yellow ones are Y.C. which are about as bad as Fuhjyyu.

Re: Accent 600W Modular Power Supply

Good point with the CWT, those secondary caps look like either CEC, UCC, or Fujiyuu, all use that 3 line vent on the top.

I believe you are right about the yellow caps as YC, as kc8 had posted a psu or something with them in it, I remember him saying it stood for yellow crap.

Re: Accent 600W Modular Power Supply

Not CWT... I'm leaning toward either Sirfa/Sirtec or Youngyear on this one.

I'm starting to see doubles here

Re: Accent 600W Modular Power Supply

UL E303928 on the unit seem to refer to a OEM-manufacture by Andyson on a CWT design. The same UL is used by Hipro.

Re: Accent 600W Modular Power Supply

According to Travis on Jonnyguru forums:

R-Senda, that's a quite small company in China.
The design is again the aged TL494+LM339 based half-bridge topology whose upper limit is at around 600W. Having seen those questionable caps on the secondary and the bridge rectifier without heatsink attached, I'll pretty sure that 600W load will simply kill it, since R-Senda intended not to make it 600W.
On the sticker 12V1/2 outputs are rated at 18A/20A but their combined output is 480W(40A) so where is the missing 2A? Those safety certification labels are most probably fake.

Hmm,
The UL on it is E303928.
According to the Johnnyguru site that's either CWT or Andyson.

Don't think it's Andyson. Looks way too much like Antec SP, TP, or TP2 units which are all CWT.

Who administers Johnnyguru now?
Looks like it needs an upgrade to correct the errors Oklahoma Wolf.

Re: Accent 600W Modular Power Supply

If you look up the UL on the UL site, it comes up with nothing.

Hiper used to have that UL number for themselves, and they were traditionally CWT or Andyson built. Not sure why it's expired... might be a recent development with their partnership with Sirfa.

A lot of those articles haven't been updated in a while.

Travis likely nailed this one... he has a lot more experience with these Chinese oddball OEM's than I do since he's from that part of the world.

Might be fraud/fake.

Re: Accent 600W Modular Power Supply

Well, perfect opportunity, a expired UL that use to be of a reputable company, put it on our psu, and advanced users will think we are them!

Re: Accent 600W Modular Power Supply

11th picture down... those yellow caps are GL. On the 8th picture, there's also an AsiaX cap with a black sleeve (so probably all of that kind would be AsiaX). Not exactly great choices.
PSU should be decent with some new caps, though.

Re: Accent 600W Modular Power Supply

Good eye.

That "GL" is GoldLink out of China. - No working site.

Agree on probably fraud/fake.

I've looked up the European markings I recognized. The sticker includes the (N) and the (FI) certifications, which is the Norwegian Nemko and the Finnish Fimko. By agreement, a certification in any of the of the Nordic countries, will give the four marks (D)(FI)(N)(S). The two omitted, the (S) (Sweden) and the (D) (Denmark), are largest markets of the four.

EMKO-Nordic Certification Service
The Nordic Certification Service is a long standing agreement between the EMKO bodies (Demko,Fimko,Nemko,Semko) as national certification bodies in Denmark, Finland, Norway and Sweden. It implies that the four marks (D)(FI)(N)(S) may be obtained by one single application and submittal. Due to the well known tradition for safety awareness in the Nordic countries, these marks on a product carries a strong message of safety.

The CE marking is the European Union regulatory conformity marking, and should have included a number for the Notified Body for the Declaration of Conformity.

Article R12

Rules and conditions for affixing the CE marking

1. The CE marking shall be affixed visibly, legibly and indelibly to the product or to its data plate. Where that is not possible or not warranted on account of the nature of the product, it shall be affixed to the packaging and to the accompanying documents, where the legislation concerned provides for such documents.

2. The CE marking shall be affixed before the product is placed on the market. It may be followed by a pictogram or any other mark indicating a special risk or use.

3. The CE marking shall be followed by the identification number of the notified body, where that body is involved in the production control phase.

The identification number of the notified body shall be affixed by the body itself or, under its instructions, by the manufacturer or his authorised representative.

4. Member States shall build upon existing mechanisms to ensure correct application of the regime governing the CE marking and take appropriate action in the event of improper use of the marking. Member States shall also provide for penalties for infringements, which may include criminal sanctions for serious infringements. Those penalties shall be proportionate to the seriousness of the offence and constitute an effective deterrent against improper use.

CE also = China Export
Look closely at the bottom of this webpage:
http://en.wikipedia.org/wiki/CE_mark
The the non-US UL looks like crap. Definitely fake. Same with CSA mark - needs a number. Actually all of the certifications look fake.

And why did they put Hi-Pot, Burn-in, and ATE as safety marks on the label? Those belong to quality control on/with the warranty/QC sticker after the PSU has been tested, not while it's being assembled . But on first and second pics you can see QC stickers on top of the PSU, so maybe the QC isn't fake after all.

Re: Accent 600W Modular Power Supply

Thanxs for your help

10stripe is incorrect.

E303928 used to be listed in the UL database as "Hi Performance Group LTD" (aka "Hiper"). They used that UL on both Andyson and CWT built units "back in the day". That UL does not, nor did it ever, belong to Andyson.

For whatever reason, the UL pulled that file. *shrug*

If that unit is made by R-Senda, then it's a fake UL.
