Similar PSU's?

**acstech** · 03-24-2008, 04:48 PM

First, go see the OCZ review here:

http://www.hardwaresecrets.com/article/491

Then, take a look at the pics of the AcBel 550w from the thread in the announcements forum. To me, they look very similar. Not identical, but close enough for one to be based on the other.

Here's some pics of the AcBel 550w unit:

That article also says that the OCZ's UL number points to FSP as manufacturer.
If those two units are somewhat related, I'm a bit puzzled. I always thought that Acbel has its own designs.

Hey, look at the pictures. Having one here I can say they look very similar.

Confuses me as well. That's why I posted it!

Caps not in same positions.

PCBONEZ · 03-25-2008, 07:54 AM

Lines are centered on cap closest to the notch.
Also note the distance from the closest cap to the notch is different between them.

**acstech** · 03-25-2008, 08:37 AM

I said similar, not identical.

I'll take more pics.

jonnyGURU · 03-25-2008, 08:03 PM

Not even close.

The OCZ is actually 3Y (not FSP, although FSP has controlling interest in 3Y, their designs are quite different) and the Acbel is Acbel.

They are similar in that they both use stacked PCB's, but the similarity stops there.

**acstech** · 03-26-2008, 10:34 AM

Ok so here's what I have for similarities:

1. D15XB60 rectifying bridge
2. ML4800CP PWM / Active PFC IC chip.
3. Both primary PCB's are marked:
"PLOTECH 1 94v-0"
"E169497"
4. 20N60 power MOSFET transistors on the primary.
5. Both secondary PCB's are marked with the PLOTECH information, and the E169497 number.

seems like standard stuff for plotech made pcbs http://www.plotech.com.tw/

PCBONEZ · 03-26-2008, 11:28 AM

I'm with jonnyGURU on this one.
They are similar but aren't the same.
I think maybe they have the same PCB designer but they are certainly different designs.

PLOTECH seems to be a PCB manufacturer and not just for PSU's.

UL E169497 is a "Standard Multiple Listing".
From what I gather that means the *design* is UL listed but anyone can physically build it.
(That allows OEM builders for approved and listed designs I imagine.)
- I'm not sure, that whole idea/situation is new to me.

This place also builds PCB's under that UL.

[Or maybe they are the USA branch of Plotech ???]

**acstech** · 03-26-2008, 11:37 AM

Yep, that's what I said, similar. Not the same. But you'd have to be blind not to see the similarity.

Jonny, I encourage you to go order one of these $30 Acbel's, take it apart, test it, and do it right. I don't have the time or equipment to be honest.

I don't have to. Already have.

The old BFG 600W is based off the same Acbel platform: http://www.bfgstore.com/ProductDetai...de=BFGS600WPSU

And I already reviewed the EvoXstream 600W here: http://www.jonnyguru.com/modules.php...=Story&reid=26

They're similar, yes. But not the same.

Yup. Plotech offers great quality and low price for OEM's needing 4-layer PCB.

**acstech** · 03-27-2008, 07:25 PM

On your review of the evoXstream 600w, I find the primary caps interesting. My AcBel uses 5 420v, 120uF Rubycons. It's hard to tell there's more than 3 though, since 2 of 'em are hidden under the heatsink. Compare pics 0534 to 0539 and you'll see what I mean. You sure there's not more than 3 on that OCZ?

Nice reviews. Certainly bodes well for this AcBel. At least the price is right on this one.

jonnyGURU · 04-01-2008, 07:17 AM

There are only three primary caps on the OCZ. As PITA as it was, I had the top half off and it was clear to see there was nowhere eles for any caps to hide.

Unfortunately, that review was 1.5 years ago and that unit long gone so I can't take any more pics for you.

Also note the D15XB60 rectifying bridge used on both. Now some things are in different places, but the similarities to me look hard to ignore. Study the pics closely.
