It was a refurbished board, so there was nothing else with it. Would I be able to buy one from a computer hardware shop, or are they specific to each board?

yup , one of those from VIP on ebay?


poppellerant is on the nail with this , just looked online coz I,ve never seen a 8 pin plug , seems they come on those new modular PSUs


however the pin layout looks like a single 4 pin plug might work ,


sorry out of my depth now , so I will back off


good luck with it

I'm using this picture, for your reference.

On the top right, there is an 4+4 pin plug, labelled JPWR2. Do you have a 4 pin or 8 pin cable plugged into this from your power supply? 8 pin is best, but 4 pin does work.

On the bottom, underneath the memory slots, there is another 20+4 pin plug labelled JPWR1. Do you have a 24 pin ATX connector plugged into this, or are there 4 pin remaining?

Pretty much all of today's PSUs will come with 20+4 pin ATX connectors and an 4+4 pin ATX plugs. You can get away with using 20 pin ATX connectors, but it's not really ideal. Usually the plugs are split, that's why I said 20+4 pin and 4+4 pin - they are usually pretty close togther, but split into 20+4 plugs and 4+4 plugs together.

Something I would strongly recommend is to examine the pins on the processor socket. I don't know if you've taken it in and out the socket when swapping, but if you have then make it a priority to check.

Take the memory out and push it back in again firmly. Don't be afraid to apply a little extra pressure to be double sure. Also, make sure the lugs holding the memory are clipped in properly.

One last thing I'd do, is just take everything out and test it on a table. Just hae the PSU, keyboard and graphic card plugged into the motherboard. But I'd be looking at connectors then CPU and memory as a priority.

We have a 4 and a 6 pin plug, we were usng the six, but tried the 4 after enfield freddy's replies above. Not sure about the other one, I will have to check tomorrow as my son has gone to bed now. We did examine the pins on the processor socket and there were no bent ones, they all looked fine.

The memory I'll check tomorrow too, and get back to you.

Thanks both for your help so far, it's very much appreciated

The 6 pin plug that you mention is for your graphic card. Does your graphic have a power plug on it for this to go into? This could be why the computer isn't turning on if it's not plugged in.

Check you have the front panel connectors connected properly, if could be something simple like the switch not getting any power.

Ok, done some looking at your parts.

Your PSU has a 20+4 pin ATX connector, so no problem there. It has a 4 pin 12v ATX connector, but the motherboard doesn't say if needs two 4 pin connectors or not - it should work with just the 4 pin connector.

I think you can ignore the 6 pin connector as it doesn't look like the graphic card needs it. But double check anyway, as it's something so easy to overlook and miss.

Something I never asked, was the system working okay before you swapped it into the new case? If so, it might be worth checking for too motherboard standoffs which could short your motherboard. Check you have enough as sometimes the motherboard flexing can cause havoc.

That's a good point actually, completely overlooked that.

Yes, we checked that, and they were all connected properly

Yes it worked fine before. I will check the standoffs as this motherboard is a lot bigger than the last, so maybe there aren't enough.

Also my son watched a video on youtube, which said something about testing to see if it was a switch problem by using a paperclip to make a connection between the + and - pins for the power.

Is this safe to do? I thought it sounded a bit dodgy.

OR the standoffs are now in the wrong places , and shorting out , please check this , its a common mistake as boards have different locating points
