I get flamed and people think ATE testing is a waste because ..... *drum roll*
The unit has no PCI-E connectors! Woohooo!!!

Funny isn't it? Safe to say that I won't be frequenting that forum anymore.

Thier just pissed becouse when your Super-Micro is still pumping the juice 3-4 years later and their OZC's and Enermax's are on their 2nd and 3rd rma's,they will be wondering if their PCIE and SATA plugs and the bling factor will really be worth it!Just go to show all that glitters is not of gold,and one man's junk is another man's treasure! I myself would give my left nut for a Zippy or a Super-Micro!

Re: I hate a PSU because it is industrial/server and has no bling.

I still cannot bring myself to concede that lack of connectors would qualify a PSU as crap. Regarding cross-loading on that unit, it did not fail it, but was not at a comfortable level either. That and the efficiency caould be a bit better. However nobody gave a hoot about the ripple or quality of components used. I'm just glad to be outta there, spending more time with the excellent techs/engineers on here and on ocforums.

Jonny, I now fully know how you feel upon being dissed by some half assed morons who have no clue about anything related to electronics. So yea, people can go back to their shiny bling bling Topower units and get an RMA# soon after.

These are good reasons to recommend against the PSU. Not lack of connectors or lack of bling.

This is a good reason to not recommend MOST of the PSU's they rail against. But fanboyism and lack of common sense clouds the judgement of most.

We're talking DFI users here. Obviously they don't have much of a standard for quality or quality control.

Re: I hate a PSU because it is industrial/server and has no bling.

lol!

Look at this. Now this shoots down any credibility they might have. Fujjhuyu is king!

Please note that Antec and DFI are working very closely together to be able to make Antec psu's on our highly recommended list. For too long we've been without Antec psu's for long-term and extreme testing, but this has changed as of today (8/15/2006). Stay tuned and you will soon see Antec psu's back on the Recommended list as we are confident that the Antec psu's are of high quality and are to be recommended as another excellent choice for DFI Lanparty setups. (choice is always a good thing!)

Take the match to the dynamite...boom!

Here is their list :-

Re: I hate a PSU because it is industrial/server and has no bling.

Hey, that is the usuall minded, ignorant & average jo`s opinion. Basically based on nothing else than junk sience & succesfull marketing + somhow fanboy fanatism.
if your are not in the elektronic field, it is usually noth that easy to get the basic SMPS things in your brain. I am a elektronic hobbyist for a long time, but i needed several atemps to understand the stuff. Last but not least reading this forum was the glue to assemble the full picture. But it needs as usuall a notoriousely sceptic mind to see what is going on there regarding HOME & SOHO IT equipment.

Hey i have build some friends complete systems and advised them what to buy. They are folowing my suggestion untill the PSu, where they have been convinced from other firends that today at least 450 to 500w is necesarry, and that a 350W FSP unit can`t supply a AMD 3500Venice box with 7600GS....... Now they have the usuall crap in like Delux, L&C etc, despite my warnings and concerns abouth that. Hey i leave them, they probably ending at Dell, if their own build system will glow to dust. This don`t worry me , my system is safe..

Re: I hate a PSU because it is industrial/server and has no bling.

Das ist richtig my friend! My room-mate had a "custom" built P4 Presscot setup being powered by a dynex/dynapower PSU. I told him it will blow up sooner than later, but he refuses to listen. I have a fire extinguiser in my room for personal use, now. :p

Re: I hate a PSU because it is industrial/server and has no bling.

My mercury AMS has no bling, but it gets the friggin job done... lol

And it probably has crap caps to boot!!

[Shroomie]

Re: I hate a PSU because it is industrial/server and has no bling.

MD's got that right. I've got an Enermax Noisetaker myself, it's well put together, and sure enough it's got the decidedly mediocre jPCE (TUR series) caps on output. Airflow ain't that great, and sure it's kinda shiny with its blue paint and gold fan guards, but it's honestly rated (Ultra, can you hear me?), has an entire lack of lights, and only the ATX cable is sleeved.

I recommended the AMS, same one MD has, to a friend. It gets the same job done, puts out the same power as my Enermax, for $10 less. I feel I got a good unit, a definite step above shiny Topowers and no-airflow Antecs, but certainly not server-grade.

And its one PCI-E connector is one more than I'll ever need...

Just becouse they use DFI boards makes them think they are high and mighty,what makes them anybetter then me,except for the fact they require more amps just to turn their rigs on,that is suppose to impress me how?

Looks like they deleted the thread, as I get this error message: "Invalid Thread specified. If you followed a valid link ...".

ATE lets you go through a good number of tests very quickly and collect the data. You wouldn't want to try doing all the 4-corner-reg/ripple and cross-reg tests manually in even a moderate volume production environment. And if JohnnyG is using giant rheostats or fixed resistors instead of electronic loads, he has my sympathy.

Re: I hate a PSU because it is industrial/server and has no bling.

Nice setup! I'll confess partiality to Chroma and HP/Agilent (HP/A rebrands California Instruments AC sources), but that's a nice dining room decoration. Do you use a varica or just test at nominal line?. BTW, my previous employer, a small COTS P/S mfr, still used a lot of the huge rheostats mounted on masonite panels with 2x4 frames. It was like walking into the 1970s to see those things.

[jonnyGURU]

Re: I hate a PSU because it is industrial/server and has no bling.

I actually prefer the Sunmoon to a Chroma because the Chroma terminals have to be "adapted" to ATX standard connectors with a connector board. The connrectors and additional length of wire actually drops the voltage enough to where I don't consider it accurate enough. The Sunmoon is made specifically for ATX power supplies.

That said, the Chroma is nice because it's modular. Have enough modules to test a PSU with two 12V rails and now need to test PSU's with four? No problem! Add two more modules to the rack! That and because you just have two terminals to hook up to load, you can load test pretty much anything with a Chroma.. but I have no need to load up anything. Just PC power supplies.

That and I like the knobs on the Chromas. You can turn the dial to increase/decrease the load. The SunMoon gives you an up and down button. Each tap of the button is -/+ .01A. Thank goodness you can hold it down for larger changes, but it takes about 15 seconds to go up only 1A.

I've never used the HP/Agilients.

Re: I hate a PSU because it is industrial/server and has no bling.

Varica? You mean Varistat?

I have a Varistat going to the Weibo PFC and then the PSU. So I can test 100~250V input.

[PeteS in CA]

Re: I hate a PSU because it is industrial/server and has no bling.

I transposed two letters, should have been "variac", a variable-O/P transformer, i.e. your "Varistat". Used "manually" the Chroma loads let you program several preset load settings, so you can switch from one load condition to another by pressing a couple of buttons. You can also program the slew (rate of change) and whether it is constant current or constant resistance mode. You can also set up a dynamic load, where you program the current levels, the time at each level, and the slew rate when changing levels.

IIRC, you can do a lot of the same things on HP/Agilent loads (also modular). IIRC, the HP/Agilent modules are on rated to voltages as low as 3V (I hope they've improved that), while some Chroma modules are rated down to 2V (or lower).

Ok. That's what I thought you were talking about.

Yeah. I've used the Chroma too. And you can do all of that with the SunMoon too. But like I said, the SunMoon is made specifically for ATX12V PSU's so it's more accurate than the Chroma for that application. All of the factories are using them, or the similar "TechRed" brand, to QC PSU's these days. They're smaller, cheaper ($3K for the one that tests 8 rails at a time and $5K for the one that tests 12) and are fairly easy to use.

[PeteS in CA]

Re: I hate a PSU because it is industrial/server and has no bling.

Re setting the current slew being a capability of the SunMoon, unless the ATX12V spec changed the slew rate specified in the ATX, you really should set the slew rate to .1A/uS. Those TL494-based designs might not handle a really fast slew very well.

Re: I hate a PSU because it is industrial/server and has no bling.

From jonny GURU testing; So essentially, the power supply really wasn't overloaded, it was just crossloaded. Which is another word for a "lop sided" or "uneven" load on a power supply.
I read where this was stated once before and it's very interesting.
I especially like your answer, just add more stuff.
