Installing a PSU

[mOeeOm]

Sorry, I suck with computers .

Well my comp is a Compaq Presario 6000(1800+ AMD athlon XP, 512MB Ram, 60GB HD, Fx 5200)and the PSU I bought is POWER SUPPLY 500W P4 ATX

Well I bought one, and now I'm installing it, first off it doesn't fit right, its too small for my comp but it still runs find and I can close the case with it being in place so I guess iz better than being too big. Now for the white plugs, there is this big thing which I connected 3 to it, and then the motherboard, how many plugs should go into it? two I found the spots for it. Now I'm left with 3 plugs that I can't find where they go. When I turn on the comp it says ''Please make sure you connectd the hardware correctly and used the correct one for your computer model''. Btw, iz a compaq, but I was told you don't need a Compaq PSU, cuz they $80-$100.

Thanks for any help.

are you speaking of the largest white plug on the power supply? that should plug into the motherboard. there should only be one plug that goes into the motherboard, assuming the athlon xp does not require a 12volt connector.

Well so far two went into the motherboard, the large white plug plus a tiny square like one, I'm left with 3 plugs now.

That should be it for the motherboard.

Make sure you have plugged in the hard drives, your optical drive(s), your floppy drive (if present) and any fans in the case. Your video card (if you have one) may also need to be plugged in.

But I'm wondering, I read Dell does this, that they program their stuff to only work with their hardware only or is that some bs? Because its not a compaq PSU, so will that make it not work? The original PSU said ''replace with a Compaq spare'', some people told me thats just bs to make extra money...I'm not sure, I'll check again.

dell re-wires their boards and power supplies so it would only work with their parts. however, you can just re-wire the cable to dell's standard, and it should work. "replace with a compaq spare" is just a marketing tool to rip off the un-informed customers.

Ok now I put back everything, and I start it up, it gave me this error saying its not connected properly, I clicked enter and the comp works fine now....is it all good or should I do something else?

 

[mOeeOm]

Ok now that the PSU is working and the comp is running good and all, theres this lil tiny fan on the motherboard thats not running now...it used to be running when my old PSU was broken, I dunno if its suppose to be a backup or what...

If there is a fan on the motherboard, it is probably for the chipset. Does it not have a 3-pin connector?

 

[mOeeOm]

3 pin detector? I dunno what is

you probably forgot to plug the cord in.

look at the plugs on your power supply. if there is a plug that has 3 pins, that should plug into the motherboard fan connector. however, not all aftermarket power supplies include the 3 pin connector. you should be fine without the fan.

If there is a fan on the motherboard, it should be turning!

The fan should have a wire connected to it. The end of the wire should have connector, which is probably not connected to anything (hence, not turning). You need to connect that connector. There may be a connector on the motherboard for it.

 

[mOeeOm]

Ok there is a wire coming out of the lil fan that is connected to the motherboard, but I laready plugged the powersupply to the motherboard, two plugs fit in, what am i doing wrong?

 

[mOeeOm]

Ok 3 more plugs left now, 2 that look exactly like the ones that connected to my hardware(CD,DVD..) the last one is th eonly one thats diff...

 

[Navid]

Another approach you may want to try is to look at the old power supply that you removed from this system. Look at all the wires coming out of the old PSU. Try to identify them and find out if there is a simillar one on the new PSU. You are looking for a connector on the old PSU that may be missing on the new PSU.

This is the fan that won't turn on, its a cooler I just found....my old PSU was really old, prob 250W or so...my new one is 500W, do you think iz not turning cuz it doesn't need coolign cuz the new PSU is strong enough?

 

[mOeeOm]

help?

Your link takes me to a page with a bunch of CPU coolers shown!

Are you saying that your CPU fan is not spinning?

Whoa! Do not turn your computer on without your CPU heat sink fan properly connected! Like others said there should be a wire hanging off the Fan on the heat sink (if its actually the CPU socket). The power socket should be located on the motherboard right near where the fan is. The wire can only snap into that one spot so it shouldnt be difficult to find and it would be impossible to plug it in to the wrong spot.

Except that he has changed the PSU in a non-standard PC. He needs to make sure that his old PSU did not have any connectors that are missing on the new one. It is possible that the CPU fan header has no power.

the CPU cooler is connected, I saw the wire and the only socket it can go into, but its not spinning when I turn on the comp.

Try turning the connector 180 degrees. Sometimes they can go in either way, and the fan won't spin if you try to power it backwards.

It's also possible that this system is designed to have the PSU power this fan. Did your old PSU have a plug that the 3-pin fan connector could plug into? I mean, did you disconnect it from something? If it was plugged into the MB and you didn't touch it, it should still be working just like it was.

Ya I never touched it, so it SHOULD be running , *sigh* why did i buy a retail product.....

There are two logical possibilities.

1- There is no voltage applied to the fan header.
This can happen if the new PSU is not plugged in properly or if it does not have all the connectors that the motherboard needs.

2- The fan is damaged. You can test that by applying 6V to the fan and observing if it turns. You need to connect +6V to the red wire with respect to the black wire. You can get 6V using 4 1.5 batteries in series.
