I have purchased a number of EVGA 850W P2 and above Power Supply Units (PSU) over the last year. I have a question about the cabling, but let's use the 850W P2 to clarify and be specific. On my 850W PSU, I have 3 VGA slots but only two PCI-E 6-Pin + 8(6+2)-Pin cables are supplied, in addition to two PCI-E 8(6+2)-Pin cables. What I am wondering is, if I purchase from EVGA a third PCI-E 6-Pin + 8(6+2)-Pin cable, is it safe/okay to plug in and use that power cable with the other two cables 6-Pin + 8(6+2)-Pin cables? I am powering graphics cards from these VGA slots that sit on powered riser cards and prefer to use PCI-E 8(6+2)-Pin cables (power the riser card with the 6-pin and plug the 8 pin into the graphics card itself) than a SATA cable to power the riser and a separate 8(6+2)-Pin cables to power the riser. 

I read the manual, and it's a bit vague. It says only use cables that were shipped with the EVGA and then the following table is provided, but that's about it.:


So in summary, my question is:  If I buy another PCI-E 6-Pin + 8(6+2)-Pin is it safe/okay to use it with the VGA3 slot while simultaneously using the other two PCI-E 6-Pin + 8(6+2)-Pin cables (that accompanied the PSU) in VGA1 and VGA2?

Please let me know what you guys think.  Thank you!

Yes you might be able to.......  you'll have to monitor & limit the load on your PSU - stay in spec.
 
You do not mention a lot of important details -- We like details of the Rig, watts can depend on hardware & OC settings
 
- PSU pin-out can be specific to Any Brand or Model --> that is why you NEED cables made for your specific PSU
 
(Bob beat me to the post, lol)

Yeah, get cables from either EVGA or CableMod.

Hi,
I have EVGA 1200w P2 PSU.
I am trying to power 4 GTX 1080 TI on my rig.
I have the following cards on my rig.
EVGA 1080TI SC2 using 1(8pin) and 1(6pin) connectors (PSU VGA)
ASUS 1080TI STRIX using 2 (8pin) connectors (PSU VGA)
Gigabyte 1080TI Aorus using 2 (8pin) connectors (PSU VGA)
EVGA 1080TI FTW3 NEED 2 8pin connectors and only have 1 left.
 
How do I power the second 8pin on the FTW3?  Only open connections left on the PSU are CPU2 and Peripherals.
 
Thanks for any help.
 
Ernie

Replace your two 6+2 + 6 cables with two dual 6+2 cables from cablemod.

Hi there,
I have a very similar question. In my case it is a Supernova 1300 G2. I want to power a Bitmain L3+ miner (consumes ~800 watts), and the two PCI-E 6-Pin + 8(6+2)-Pin cables are not enough, I need one more of those. Practically I have one (from a similar EVGA PSU) but before trying out I would like to know and to make sure it won't hurt anything if I use my PSU with 3 pcs of PCI-E 6-Pin and 3 pcs of PCI-E 6-Pin + 8(6+2)-Pin cables (instead of 4+2 pieces).
Thanks for your input!

What other evga psu do you have?

Hi there,
 
I have another Supernova 1300 G2, powering a 6 GPU mining rig.

You'll be fine then.
