Graphics card PCI wire problem...

[Jonj99]

Hello guys,

 

Please bare with me on this short message. I know it sounds confusing so I attached some pictures to help out!

 

Right so I've just recently bought a gtx 1070 which has a PCI port for 8 pins. My old graphics card was a windforce gtx 760 which had a 14 pin port. The PCI cable I was using had a 6 + 8 connector which made 14 pin holes, but it only had 11 wires attached, 5 wires on the 6 hole connector and 6 on the 8 hole connector. First question, was that fine? (See pictures below)

 

Second question can I take 2 wires from the 6 pin connector and add them to the other 6 pin connector with 2 spare holes and make it an 8 pin connector? 

Doing some googling I found that the red wire is 5v, yellow is 12v and black is ground.

 

Third question, when I Google 8 pin connectors they all have different ammounts of yellow, red and black wires. E.g some have 4 yellows and 4 black or some have 3 yellows and 5 blacks and it's really throwing me off, I don't know what to do? 

 

Any help would be greatfully appreciated! Sorry if this sounds like a stupid thing to ask and thank you kindly in advance for any help!

Why not just buy new cables? They are not too expensive, unless you are on a budget.

First things first, you don't just need 8 pin, you need 8 pin PCI express. The CPU also does 8 pins but they're completely different. 

Second, you shouldn't use molex converters. You should upgrade to a power supply that can actually deliver the correct power required.

throw your power supply away if it doesn't have an 8pin connector it's probably junk

Okay thanks, I'll upgrade my PSU. It was a Corsair CX500M. I didn't realise technology has updated and they're old school now. Know of any decent PSU's? I'm not on a budget but 500w is enough to power my system

The cx500m is absolutely modern enough, did you lose the cables? It should include PCIe cables with enough pins for a 1070, and you can probably get replacements from Corsair.

I must of lost the cables, I've moved house a few times since I built my PC 3 ish years ago. All I have is an 8 pin with 6 pins and a 6 pin with 5 pins. If this PSU is fine then I'll just buy an 8 pin PCI express on Amazon like you said

Yeah you should Google "Corsair cx500m PCI Express power cables" to see if you can get them

I hate when people are like - JUST THROW IT OUT AND BUY SOMETHING BETTER.

 

Man, I have a box of cables...weighs like 50 lbs...personally Id rather TROUBLESHOOT a problem than to just spend more money on it.
