I have an old PC that I decided to bring up to date by buying and fitting some new components - a Corsair RM 750W PSU, a Hero VII Maximus board, and an ASUS Geforce GTX760 video card.

I had some issues on my attempt at assembling the new parts in the PC - it wouldn't post at all - so I repeated the exercise checking each part for compatibility. When I first installed the video card I hadn't connected the power cable - I just powered it up using the Mobo. Everything ran fine until I connected everything to the video screen - the first message was "please connect power supply to the video card". So I shut down and connected the power cables. I had a 6+2 and an 8 pin cable and hooked it up - I connected the 6+2 to the video card and the 8 pin to the PSU. The system wouldn't post and now I can't get back to point where everything was at least looking like it was going to work. It's dead - no lights on the mobo at all.

How do I get back to square one without taking everything apart? And just how do I connect the video card to the PSU?

As you can probably tell I'm a neophyte at this kind of thing - so answers designed for idiots appreciated please!

The RM750 has enough pcie cables not to need those adapters.




Used the validation from microsoft?
Reactivating doesn't work? Maybe contact microsoft...

Thanks for your reply Vic.

I can only see the 6+2 pin connector on the video card - do I use all 8 pins or just the six? And the 8 pin at the PSU?

The "instructions" in the ASUS manual for the card are laughably brief and uninformative! I presume they assume that if you are fitting this kind of thing you know what you are doing!

I have - that actually led me to breadboard the set up in the first place! Unfortunately fitting the 6+2 to the video card and the 8 pin to the PSU didn't work - it resulted in very dead machine indeed. And my problem is also that disconnecting the power cable from the video card and PSU doesn't seem to restore the system to the point I was at before getting the error message - it is now dead as a doornail. Do I need to dissassemble the whole thing and try again? Or is there some way to restore it?

Okay, so I went back to square one - I removed the motherboard and other components from the case and added them one by one, connecting the power and starting things up each time. I left the video card until last. I first added the video card without connecting the power cable and the motherboard started working, lights came on on the video card and all looked good. However once I switched everything off and then connected the power cable (6+2 at the video card and the 8 pin at the PSU) the whole thing was as dead as a dodo. So I took it all apart, repeated putting together the whole thing item by item (nothing seemed to happen vis a vis resetting when I took the CMOS battery out) and tried again with just 6 pins of the 6+2 connected to the video card - still dead. I then repeated the exercise twice more with a second power cable inserted into another 8 pin slot on the PSU. No success.

So it isn't the power cable, and it isn't the particular 8 pin slot on the PSU that is at fault. The video seems to be able to power up drawing power from the motherboard but this isn't enough to run the card in earnest.

I have to admit I'm now tending towards sending the card back to Amazon and buying something else - I feel particularly aggrieved as I felt like I was just short of the finish line only to fall at the video card! Perhaps a GTX970 if my case will take it?

So, after boxing up the ASUS Geforce GTZ760 for return to Amazon, I fitted the Gigabyte GTX970 - I was a bit surprised it only came with short PCI-E to molex cables but managed to find suitable cabling from the Corsair PSU box (not tidy but a work-around that does for the moment until I pick up something a bit neater). Started everything up without any problem at all, ran the drivers and I'm away. I'm probably way over-specced for what I use the PC for but I'm hoping I won't need to bother with it again for several years. I tried Rome: Total War 2 with it and everything looks way sharper - of course, as is the way of things, I'm now thinking a new monitor might be good....

I was slightly surprised that my Windows 7.1 now thinks it is an illegal copy though - and refuses to accept evidence to the contrary!

Thanks for all your help.

Last night I switched on, got the "you're running an unregistered copy of Microsoft...blah blah" and clicked on the "validate" option and this time it decided I was legit! So now all done - and I feel absurdly pleased with myself - my wife was convinced she was going to go to PC World to get them to repair my mess.

Thanks again.
