NEWTON POWER NPS-180 Can't Start

Re: NEWTON POWER NPS-180 Can't Start

Are you leaving the jumper in place or removing it after you make contact?

I do both but nothing happen.

OK.............................. But from now after short green and black nothing happens. Fan doesn't twist any more. T_T

May me a controller is bad now.

Re: NEWTON POWER NPS-180 Can't Start

Most standard PSUs I've seen will start with no load since the minimum load resistors inside are enough to get them to start. However, this is a non-standard PSU, so it wouldn't surprise me at all if it at least needs a few disk drives connected.

Not my experience but I don't dink with gutless wonders very often, they go straight to scrap.

OP also posted +12v was at 10v and at least some of that may be that there is not enough amps on +5v to regulate properly.
Need to see what +12v does when +5v has a real load.

Remember you need to put the bulb on the 5v rail not on the 12v.

Re: NEWTON POWER NPS-180 Can't Start

anything that will put some load on the PSU should do. even a 12V halogen light bulb or something like that.

i usually use a couple old 2GB HDDs. If something goes wrong, nothing of value is lost..

Ahh...I don't have old HDD. I will use 12V halogen instead.

Thank for suggestion.

OK. I don't know it before. I will try again tonight.

Re: NEWTON POWER NPS-180 Can't Start

That PSU is in a case. - It has drives connected.

Some modern PSU's will start without load, but not very many.

The people in -THIS- forum know what they are doing and make few mistakes.

Sorry I miss understand in it. I never know before and I will follow your instruction.

Fine. I need to put HDD drive, isn't it?

And I will report you back if it works.

PSU will not start without a load.

They do not make these schematics public.

Why this psu doesnot start like several psu?

Re: NEWTON POWER NPS-180 Can't Start

It may be a short on the drive drive.
Try a different drive.
If it does that again it is the PSU.

I'm not connect any drive to PSU. Test the PSU by short green and black together and power not turn on, fan twists, and then down.

After that I replaced all CAPS in secondary module, But problem stills alive.

How can i do? No one know about a schematic of it.

Re: NEWTON POWER NPS-180 Can't Start

You said you were repairing it because you couldn't find one and you want the system back.

Replacing it to get the system back doesn't keep you from fixing the old one,,, now does it..

I love this old dell and I decided for repairing.

This system not important now because i have an other machine.

Re: NEWTON POWER NPS-180 Can't Start

So it looks like this then?
-
That is a very common Dell part used in.
Dell Optiplex GX60 Small Desktop
Dell Optiplex GX240 Small Desktop
Dell Optiplex GX260 Small Desktop
Dell Optiplex GX270 Small Desktop
And some others.

Should not be hard to find even in THAILAND but search for Dell PSU instead of NPS PSU.
There are maybe 3 Dell PSUs that fit but that are not NPS.

Also now that we know exactly what it is some members may actually have one to look at/check to help answer questions.

.

Replace it?

Why we not repair it? I have tools and knowledge (maybe a little bit).

Re: NEWTON POWER NPS-180 Can't Start

It may need a minimum load on 5v for 12v to operate correctly. Connect a spare hard drive to it and see if it goes in spec.

Good idea.
