PCIe connection?? PLEASE HELP!?

[riaan99]

So I got myself a nice upgrade, GTX 1070 G1.

Connected all "8" PCIe pins but still get this message when I power it up. :

PLEASE POWER DOWN AND CONNECT THE PCIe POWER CABLE(S) FOR THIS GRAPHICS CARD

I measured the voltage on the cables, 12.54V between all of the yellow and blue wires to 0V (black wires)

What to do next???

Specs?

 

[riaan99]

532W PSU
Core 2 DUO
Intell motherboard, no clue what model...

Yes, its an old PC..

You sure you using the PCI-e power cable, and not an 8 pin cable for the motherboard?
You mentioned a 'blue' wire, and the PCI-e cable usually have just yellow and black wires.

What PSU exactly is it?

Most likely the board doesn't have a UEFI BIOS to support your new card.

System is too outdated to run newer cards.

PSU is also probably not up to the task.

I'm sorry, its a Power man 550W PSU..

Not a good PSU , VERY POOR quality and read my last post.

Okay, so I replaced my CPU with i3 7100-3.90GHZ and Main board with GIGABYTE B250M-D3H - B250...

No difference at all...I'm sorry but I can't see that it is the power supply will make a difference..surely it must power it up on start up, I would understand if its under extreme load that it might switch off or hit me with a blue screen...I'm thinking the problem must be with the card... Any other suggestions anyone?

I'd put considerable weight in everything he suggested to you.

Can you not get a good quality PSU to try out?

I'm an electrical and Instrumentation Technician, I know something about power...it just do not make sense, but okey I'll try to get my hands on a better Psu.. The stores are closed here in south Africa at the moment, I'll let you guys know the outcome..

Regardless if it's not the PSU, I wouldn't risk it with that system anyways.
Also, tho the voltages may test ok without load, it's hard to say if the Amps and voltage are there under load.
