I didn't think this was possible - an 'explosive' Delta!

Antec's VP350 exploded when Hardware Secrets tried to overload it

True, it did deliver 350W, but still, being a Delta, I would have expected OPP.

Antec probably told them to cheap out on some parts here and there..
The efficiency figure speaks for itself lol

It says in the review it's an FSP, not a Delta.

Also while OPP would definitely be nice they pulled 475.3W from a 350W rated unit before it exploded which is well beyond a reasonably expected overload.

Yes, I know that there are some real idiots out there that would try to run 2 high end video cards in SLI/Crossfire and a Quad core CPU off of a 350W PSU and Antec and their OEM should use OPP to cover their but in such a situation

They are wrong. It's a Delta. FSP never use those black transformers and they never use Taicon caps. Their low end capacitors are always Capxon and Teapo.

That thing doesn't look like a Fortron. At all..

I worked at Delta, 1998-2001. There are aspects of the construction of this P/S that are consistent with what I saw in our products (e.g. the green-painted toroid core in the I/P common mode inductors and some other I/P filter details). But the O/P cable doesn't look tight, usually one of the I/P common mode inductors used an E-core, and Delta used UC384X PWMs or an Delta-custom controller. I think two-switch forward converters were common, but I could be wrong on that. Things change in 10 years, but my guess is that this is not a Delta design.

To be fair if you're daft enough to load a 350W power supply to 470W you shouldn't be surprised when it blows up, lack of OPP aside.

Re: I didn't think this was possible - an 'explosive' Delta!

After my post above, one thing I noticed nagged at me. While looking at the construction pix I noticed what looked like it might be a custom supervisory IC on the O/P side. This would be the analog equivalent of a gate array, a chip family with a bunch of uncommitted functional blocks (references, comparators, etc.) that a customer could connect to their specification. Delta had such a proprietary supervisory IC, either the DNA1001 or DNA1002 (don't remember which, the other P/N being a combo PFC controller, 384X-style PWM). The review identifies this supervisory IC as a "DWA106N161" (looking at a pic, it might also be a DWA106, with "N161" being either a customer identifier or part of factory/line/lot/date coding). Either way, this differs from Delta's part numbering scheme in two ways. As I said above, things change in 10 years, but this seems to support my guess that this Antec is not a Delta design.

Should a 35% overload trigger OPP? IMO, that's in a maybe area. OPP typically isn't very precise. I would expect a designer to pick a OPP threshold somewhere in the 25%-40% overload range.

As for an end user overloading their P/S by that much being daft ... well, some users are well-informed, and some see bright flashes, hear loud noises and smell bad smells in their electronics.

Well we do get CapXon primaries, so it could be a FSP... then again, with the Taicon secondaries, black transformers, and small PCB it looks so much like the Delta i have lying around in a corner somewhere.

Re: I didn't think this was possible - an 'explosive' Delta!

Geez! If I had looked at the Intro page of the review, I would have found:

While the VP450 model is manufactured by FSP, the VP350 is manufactured by Delta. Therefore, they are based on different designs.

Re: I didn't think this was possible - an 'explosive' Delta!

Maybe the OPP was faulty on that unit

Re: I didn't think this was possible - an 'explosive' Delta!

Geez! If I had looked at the Intro page of the review, I would have found:

They changed it. It originally said that the VP350 was made by FSP.

I might have been able to use that excuse had I read it before it was changed. I only came across the statement that it was made by Delta when I was looking for pix or text that said/showed who made the fan and the IEC-320 inlet (I'm rather familiar with the Delta logo).

Did anyone notice the piece of crap Elite main capacitors?

[Th3_uN1Qu3]

Re: I didn't think this was possible - an 'explosive' Delta!

That's CapXon not Elite... you were looking somewhere else.

Re: I didn't think this was possible - an 'explosive' Delta!

Capxon aren't much better, though.

It drives me up the wall that Antec use non-japanese caps at all after the Stupidpower disaster. Personally, I don't think that bad caps should ever under any circimstances be used at all. It only saves like 50c, and if the manufacturer is really that desparate for it, I'll quite happily pay 50c more for the power supply.

I'd even pay an exttra $5 if I knew it had popymer caps

Well, maybe that will be all it costs to get polys if my PSU polymod experiments work out.
