Pls give me advice on best electronics forum (I need to set up a budget for ATX PSU testing equipment)

Anything but EEVblog, I was banned for no reason (I forgot my username and the whole forum thing just fu@ked up)

 

Thanks in advance.

this is some of the good gear I am thinking of... Any thoughts? thank you.

Maybe ask on jonnyguru forums.

 

Try making another account at eevblog, but either way it's more of a general electronics forum, testing power supplies and psu testing equipment is more of a niche and I doubt you'd gonna get good replies.

 

The links you gave ... yeah, I guess that programmable dc electronic load could be used, but it's not optimal for atx power supplies, where you can have multiple rails and you want to put loads on 12v, 3.3v and 5v at same time

 

You don't need a 4 channel oscilloscope to test power supplies, a one channel or two channel is plenty...

 

Have a look at the recent videos about power supplies on Gamers Nexus on Youtube at the equipment they use, and i think they have also articles on their website where they list the equipment they bought. 

Jonnyguru uses/used similar equipment 

If you want to see Chroma or Sunmoon hardware used in factories for testing before shipping, there's a bunch of factory videos on Gamers Nexus and maybe you can read the models from the videos.

Which is defunct lol.

easy way 
buy a equipment design for ATX psu testing like sunmoon SM8800.
A variac for changing main voltage . but I prefer cheap AC source because it have isolate tranformer inside (SPWM) and can set current limit to prevent your DUT blow up
Scope like rigol Ds1000z is good. I have used two of them

I got banned from EEVBlog for no reason and I can no longer create a new account for it.

Misunderstood the intent.

I think it depends what sort of testing you need to do.   Do you just need to check the voltages, ie: that the power supply is working?     Testing them under load is a bit more advanced and would require a more expensive setup.

 

If you just want to check the voltages, there are cheap ATX PSU breakout boards, and also voltage checkers.   For example only:  PSU tester,   PSU Breakout

Oh, hadn't realized you need to push those at the same time. So I'd better forget about that one lol

then something like this would do? doesn't it?

 

https://www.bkprecision.com/products/oscilloscopes/2190E-100-mhz-1-gsa-s-2-ch-digital-storage-oscilloscope-dso.html

 

or 100 MHz bandwith, 1GSa/s sampling rate is not enough?

SM8800, I can't find it here in Mexico. How much should it cost?

is it? I made an account last year but never used it. RIP I guess.

yes it it since a while ago

I mean a full lab for testing PSUs, trying to emulate what aris does @ tomshw and TPU

 

if not, at least GN like level of detail in reviews

you can contact directly to sunmoon. http://www.sunmoontec.com they have local sale in US. that good for you.
if you want something like Aris you need spend more money than Sunmoon equipment. and you need learn to design the software control via SCPI ,because chroma sell software control separate and it not cheap too. (I have use labview in before ). but for ATX psu review I think sunmoon is enough.

You think sunmoon is enough? ok, roger that, thank you
