I am getting this motherboard soon and i am slightly confused about the PCIe slots and it sharing the bandwidth, this was taken from the motherboards website (The PCIe x16_3 slot shares bandwidth with PCIe x1_1 slot, PCIe x1_2 slot, USB3_34 and eSATA. The PCIe x16_3 default setting is in x1 mode.) does this mean i won't get full 16x speeds when using a PCIe 16x graphics card?,

So i am guessing if i use a single graphics card in slot 1 then i will get the full x16 speed, but if i am using two graphics cards then it will be split x8 for both?.

I was just building this computer up and went to connect my PSU up to the motherboard and realise it is different, it seems to be a EATX connector and not a ATX connector like i have, didn't think these was different?.

I have managed to get a 20 pin connector to a 24 pin convertor now but it still isn't working, do i need to connect the 12v power up as well, didn't think that would matter as never used it on the other board?.

I just quickly went and got this, but the system still doesn't seem to be powering up, really confused now.

i dont see anywhere in both your posts that mentions you trying a different psu ?
as you say its only a 20pin connector on your current psu then you definatly need a new one as 20 pin psus are very old and definatly not suitable for new hardware

If this is same psu as overclocked. You may have blown psu. Does PSU have its own fuse.

A 20 pin ATX plug will work just fine for testing purposes where a 24 pin ATX socket is onboard. DO NOT try to use the 4 pin plug with the yellow pair and black pair for anything other than it's intended purpose (CPU). These connections are specially rated and are fed from specially protected circuitry.
If your new motherboard/pro/memory are much more advanced than your original, you will undoubtedly need to upgrade the PSU anyway. Don't go for the cheapest you can find and don't try to botch with extenders/splitters etc.
Is the original motherboard one that was supplied by the likes of Dell or HP etc? If so, that could be where your problem lies as some of the bigger vendors did not adhere to the ATX/BTX standard pinout.
It's Wiki I know but have a read here.

I haven't tried another PSU as it is more money and i thought the PSU that i have now would be fine to use if i am not going to be running high end graphics cards, do you think it would be the PSU at fault here then?.
|
|
|
|
It could be, i am not sure if the PSU has its own fuse, how would i find that out?.
|
|
|
yes it sounds like it as your having the same issue , corsair are a good brand something like
http://www.ebuyer.com/271798-corsair-430w-v2-cx-seri... cheap and with a 3year warrenty
also with that you will have all the proper connections for your new board

Normally you can remove top of PSU case and Fuse would be on Printed Circuit Board. This fuse is sometimes soldered to board. However, as you have lights on Board it is probably the 12V Circuit that has failed.
As others have suggested, get yourself a decent Power supply with correct connections.
Did you connect the 20 pin to board as per previous information. If this did not work adding 20 to 24 connector will not either.

Called up my local computer shop today and spoke to him about my problem, he said i could take my PSU up to him and he would test it before i bought a new one, so took it too him and he tested and said it was broke, i've bought a new one from him, he was going to sell me a 500W but i said about that in the future i would want a decent high end card to use with it so he said i would need a 700W one so bought that instead, just opened it up and can see it has the 24pin as standard but just checked the 12v connector on it and can see it is a 4pin just like my other one but my motherboard needs a 8pin, would this still work?.

does it have to of them 4 pins some can be split ? if not its probably a cheap non branded psu and should be taken back , all the branded new psus will have 8 pin connectors
buy a corsair

If you can't get a corsair I would also recommend an Antec PSU, they are great.
BUT beofre buying anything else make sure it will work with your new Mobo and fits in your case.
|

As previous stated the 8 pin is 2 x 4 pin for extra power. and stability. What is the 12v power current on your psu and what is calculated requirement.
If you are future proofing best to change now.

Called the computer guy up and he said just use the 4 pin in the 8pin connector and it should work perfectly, he said the only need for the 8pin connector is if i am using a intel extreme processor and then i would need a new PSU anyways.
|

What make is the PSU? Someone may be able to advise if it is any good. Cheap PSUs really are a false economy; it's not as if you buy them very often (not if you get a decent one anyway).
I'm with the others who have suggested Corsair; it's the lifeblood of your PC so why compromise?

If it works at the moment ill be happy with it, just want to get my computer up and running, spent a small fortune on the motherboard and cpu etc and haven't even got it working yet, just want to start playing on it instead of fixing it, this is the PSU i think.

May not be the best psu.But hey get your rig moving.
Look at reviews on amazon re games and long term power.

Got it working now, but got another slight problem, my dvi to vga convertor doesn't seem to fit into the dvi port on the graphics port on the motherboard, the one on the board seems to have a line on it where on the convertor there seems to be pins next to the line so it wont fit in?.

Sounds like you have a DVI-D socket, which can only be used with a digital monitor. See http://www.rm.com/Support/TechnicalArticle.asp?cref=...

Look here

You can get DVI-I and DVI-D
DVI-D can be 24+ 1 spade or 24 pin + spade + 4 audio. You need a special converter cable for a digital to VGA
appears to have a d-sub vga output

Cleared the CMOS and plugged in the VGA and it worked fine now, strange didn't work before when i used just the VGA.

Got it all running now and CPU is running between 50-60c idle, is that normal?.
