No Power?

I have a thermaltake 430 PS and i was trying to use it with a Kocab 18P MB. I have everything hooked up the way in the manual (all the connections have labels) But it won't boot up. Will the PS work with that board? The dead board had the 20 pin with a 4 pin connected to? Does it have to be used? Sorry if any of these questions are dumb, my first time starting from scratch.confused

 

Hi there, The 4 pin plug needs to be used, If you have a 24 pin connector, the 4 pin extra can be unclipped, and should not then be used, just tied up out of the way. If it is 24 pin -- Do not use the unclipped 4 pin connector. If your board has not got a 4 pin plug socket, then you have a problem.
Nothing is too dumb to ask - how do you think the rest of us learned ?

 

Yup...have problem.:cry ..And Newish MB suggestion for that power supply?confused

 

Chris, give us a clue or two.

Are you trying to replace a motherboard you believe has died? If so why did it die?
What makes you think the psu and the new motherboard are both working?
What is the situation with the processor and memory?

OH it died alright. I was working on putting in some new memory and while i was leaning over to just look at it my GF bumped me and my hand cruched the MB!:mad :mad :mad And the Kocab that I'm trying to use was givin to me by a friend who just put a new MB is and i saw it working. And the PS was working when i turn it off before i crunched the old board.confused

 

O.K.
Let us assume the psu is functional and that the old motherboard was mechanically damaged.
That should leave you with a functional processor and memory.

You did, however, not answer all the questions. I asked these because failure or incompatibility of any one of psu, processor, memory or motherboard will halt the startup.

It is possible that your memory and or processor are the wrong sort for each other or for the new motherboard.

It is possible that you could have damaged memory and or processor removing / inserting them. Don't forget that modern motherboards carry some power even when the pc is shut down. Thus you must disconnect from the mains when working on them.

Incidentally I posted an answer to your other question in another thread, guessing you were somewhere in Europe. The location field in your particulars might have helped here.

If you have not got a manual, download one in pdf from Jetway site ---http://www.machspeed.com/manuals/VIPER/NF18G5A.pdf
Memory check-PC DDR 2100/1600/2700/3200- 184 pin
CPU -AMD Athlon, or Duron , socket A(462)
No plug point for 4 pin- will not matter, as long as you check that the wiring in the main connection tallies with the pdf manual.
Leave 4 pin off.
Go through manual check all connections.
Check DDR Ram type, and that the ram is seated properly, as it will not start if ram is not seated properly, and it is not always obvious, lift out carefully, and gently ease back in, -if a good fit the clips will close themselves, but push them in to lock to make sure.
Looks a half decent mothewrboard, by the spec, - you don't need the latest to get a good service component.
Most psu's seem to work with a lot of boards, it is only when you want extra performance that it shows.If the psu was working before you changed the motherboard, unles you dropped it, or, something daft, it should work now.
I have had many a 'dead' system, jump up and run, after jiggling with the ram.
Have a juggle about, in different slots, even.
Keep us posted

I haven't had time to work on it lately. To much orther work..:*** But i have time this weekend to work with it again. The processor came with it though so iI know it ok. And the memory was some i had in storage so it might be the culprit??? Also gonna try with a different Vid card to. But most of it has been in storage for the last ....while anyway but i hope it's all still good.rolleyes

 

let us know how you get on

Studio T

 

I'll try to work on it this weekend. I'll jump on if any other problems come up!rolleyes

 

If you are checking your graphics card, check compatabilty, while you are at it. Some boards will only run a 1.5 volt, and can mess up if a 3 volt is fitted.

 

Sorry it took so long. I worked with it over the last few weekends, tooke everything out and cleaned EVERYTHING! Even put ned thermal goo on the CPU. Replugged everything triple checked and then i pushed the power button and then......nothing? So I checked them again and still nothing. I know the PS works. I know the MB worked when I got it. Now I'm just lost! Since this is my first "from scratch" computer,sorta, I don't kow where to look next? The only thing i can guess, I'm reaching here, is that the place where i plug the power button and the HD led and reset switchis missing a wire from the speaker connector? And from the reset wires? the plug has three - a GND - a RSTSW - and a NC pin. The reset plug from the front only has 2 wires to plug in. I'm sure that's not it but I'm outa Ideas! Anybody got any ideas?

 

Chris please confirm the following

Have you done any tests to proove that the power supply is working? Try it in your friend's pc again?
Has the rectangular 20 ATX connector from the power supply got all the leads connected? In particular is the white (-5volt) lead present?
Have you connected the processor fan lead to the processor fan socket on the motherboard, not to the system fan socket?
Ditto the other way for the system fan?

Any of these will prevent the system starting if wrong.

The only connector you must have from the front panel is the on/off switch, connected parallel to the long side of the motherboard header to the two pins adjacent to the missing one. This is labelled pwrbtn in the manual. Check you have not placed it at right angles across the header.

Finally please confirm the processor and memory type.

Chris
Have you rechecked all Studiots little notes ?
Like he says- the power switch leads are the main ones.
-NC= no connection.
Speaker often only has two wires= on board speaker connection,- allows you to hear it beep when you start up.- If a speaker wire is to connect differently, it is possible to lift the plastic securing clip, on the offending connection, with a tiny electrical screwdriver, and ease the pin out complete with wire, and push into another hole, if needed- fiddly, but I have done it a few times.
Otherwise, have you another friend who can try his psu in your PC?

 

When you try to Power on, Nothing happens at all?

Check The front pannel wiring/case wiring check mobo manual for details & pic's, you only need the power switch & maybe the reset

Is the rocker switch on the back of your PSU on?
_________________________________________________________________________

Reset the MOBO CMOS then try to boot
Anytime a Mobo is swapped from one system to another it's always best to reset the CMOS ( this will clear any Memory, CPU and voltage settings and return the MOBO it's default settings)

Test your PSU, the Thermaltake 430 are junk to begin with & if you broke your old MOBO while it was running with the Thermaltake, you may have dammaged it too


Another thing to check for is short or grounded MOBO, are all of your MOBO standoff in the correct position? no extras!

 

Is the rocker switch on the back of your PSU on?

That made me laugh ASUS! Seems like every time I move a computer I hit that switch. I wasted a LOT of time because of that little button. Good suggestion.

E

 

Yup,the switch is on. thought about that about an hour into rechecking? I got to be missing something.confused I followed the pictures and directions. Maybe power switch???? Not sure how to check that....yet....

 

The white lead chris? Your boards needs it, not all psus have it.

Studio T

 

Huh? White lead? I so close to taking it down the road and let my nieghbors 12 Y/O put it together! ha ha I know he's built 6 computers since they moved in 2 years ago. I get so tired of hearing how "smart" he is all the time.

 

Listen to Asus,-------------Page 10/11 of your motherboard manual, shows settings, for FSB, and cmos, and gives you a hint at getting some life from the computer, which, although it says after overclocking failure, might be worth a go, for your non starter situation.
----Keep Pressing the Ins key, and the power button,to recover standard default, as it says the cmos will keep any faulty data, and the motherboard will play dead.

 

Tried that a few times.I still am getting nothing? I hate to drag this out so long! Not to sound so stupid (in don't care for the word NEWBIE) but shouldn't the fan on the PS come on at least? I'd switch out the PS with this computer but it's a Dell so ...you know.And were would the lead wire run to? And my other MB was broke while it was out of the case. so no shorting out there. And grounded....I think so. and exactly what are/is MOBO standoff?And at the risk of sounding REAL STUPID parellel = long side of the board right? And i cant test much of anything now my buddy moved to Texas, sold my other computer rolleyes .I thank eveyone for there help though, meant to do that earlier. to test my PS can i stick my tounge to a connector to see if it works ha ha ha. But most of the suggestions I have already done. so either my MB died in waiting or the PS is really junk now?? Guess i could part it out. If i knew what was working an what wasn't?!?!?

 

Sorry did you not read this post? You certainly have not answered any of the questions alot of geeks are trying to help.

The following thread is instructive

No, Chris a psu requires a special signal FROM the motherboard before it will turn on.

At the risk of wasting my time I will offer this WARNING

Dell powersupplies and motherboards are sometimes wired up differently from everybody else. The result of connecting one of these to a normal psu or mobo is always blue smoke and a lot of dead components.

Studio T

 

yeah I've done all the things ASUS suggested. I don't have anybody who will let me use there computer...don't trust me??? the CPU fan is connected in the right slot. the memory is seated properly.the only unknown is the graphics card. I belive it's a 1.5?? not real sure it's been awhile.I really don't know why it won't work?? and white powerled. It's there.

 

ok i can see i'm getting on some nerves. I kow dell has it's own "style" of things, i wasn't going to try that route. But trust me I have followed each post suggestion to the letter. Over and Over. So It's either my MB is bad or the PS is shot.The only thing i forgot to say is there is a Blue and a white wire coming from the area where the power button is. It plugs into a plug from the PS VIA an adaptor.I have another boardcoming from ebay. nothing special just average MB.NEW though. so if it don't work...Sorry i got onya'lls nervous. I would get miffed to if some idiot keep asking so many questions.

 

Chris you must trus the Geeks experience as well - to offer the most likely and easiest to check things first before moving on to more esoteric possibilities.

If you have connected everything according to the book and it does not attempt to fire up you have a faulty component. It's really that simple.

I don't know how close to civilisation you are based but power supply testers can easily be had in the UK for £5 to £20. I carry one around in the toolkit.
If you take your psu into the local computer shop I expect they would test it for you in the hope of selling you a replacement if it is dead.

Studio T

 

That's probaly what I'll do. Take it to the local shop and have them check it. I can't stand to take anything anywhere to have someone else fix stuff for me until I EXAUGHST ALL my resources and I just get to mad to work with whatever it is anymore! HA HA I just hate to have someone else fix my stuff if I can do it. I ain't knockin the help I get, I thank EVERYONE for helping!!But i have heard that my PS is crap, so i might get a new one anyway. They ain't real expensive. Definitly don't need a 1 Kilowatt meter spinner!!! But I do thank everyone!!

 

We would not want you to leave it at that.
I suppose really, that the communication side had a little bad patch - as it will when you are trying to understand all that is suggested, and we are all trying to ensure you understand.
When you have the psu checked, and whatever else you decide (an old motherboard can be fickle) - if you still need help, come back , and ask.
Try answering each suggestion, even if you say -Studiot, 1/no, 2/cannot find it, 3/ etc;
But not all at the end , as you did now, - as we cannot see what you are doing, without the words to describe it, at the right time.
Don't worry if one , or, two of us get a little peeved, - they ought to meet my missus, - we learn to accept each others ranting and raving- BUT STILL MAKE REALLY GREAT FRIENDS.
Sorry we have not helped you to make it work, without having to go to get things tested- sometimes, that is the first option, but it gets put off.
Keep on fixing all that you can yourself, it is one way you could oneday become a Computer geek.

 

Thanks Baklogic and I'll remember to avoid your missus.

Studiot,
Like everything else, she grows on me (like Roses)- but it's true.
I have started getting to know a few great , unselfish, people, who give time, and advice to those still in the myre of computer jargon, and misleading abbreviations, who sometimes become frustrated, because, they find our simplest wording , still confusing.-Not realising that they have not told us if they have tried to do what was suggested, (probably having done it, and just think somehow that we can see that they have, but they forgot to tell us)
We have probably all been there, not having a clue where to look, nor, how to get our computers working, when it went wrong .:cry
Your experience is a great help, mine is slightly different, Fred, ASUS, and the others that I have seen doing their best to help someone get out of that corner, where someone cannot otherwise find an answer.:tas
I hope I can help a little , now, and again, with my different experiences, but we will all learn a little more from each others particular specialty (if we have one)
Sometimes we will want to tear our hair out, but as I have less now than I used to, I have less chance of finding anymore to pull out.

I think we all have a great rapport here, and I am extremely pleased to be allowed to squeeze in now, and then
