PCI-e 6-pin/8-pin

[airdeano]

looking at all these wires and keeping them straight and trus is one big PITA!
the question i pose to the group:
using a single rail PSU, i should be able to gang power all 6-pin 12v+ and 6-pin
12v- by a single solid copper wire 10/12gauge or like....
making a jumper on each pin location for the 12v+ and 12v- to connect coresponding
terminals to. so now instead of:
1x 6-pin i'll have two wires not 6
2x 6-pin i'll have two wires not 12
1x 6-pin and 1x 8-pin i'll have two wires not 14

same as well on the EPS 8-pin and the 24-pin 8wire instead of 24..

noting that on the 8-pin, the "alternate" 2-pin is a double ground to make the Overdrive
in CCC function and cant see what it controls on the nVidia side..

looking to streamline the cable management of a PSU.
my basic take away is on a single rail PSU there are 8 gangs:
common (ground/earth) (motherboard power, pci-e power, EPS power and peripheral power)
3.3v+ (motherboard power)
5.0v+ (motherboard power and peripheral power)
5.0v sensing (motherboard power)
12v+ (motherboard power, pci-e power, EPS power and peripheral power)
12v- (motherboard power)
power_on_OK (motherboard power)
PSU_on (motherboard power)


anybody got any 'sperience in the 6-pin in 8-pin location?

The addition wires are using to parallel to distribute the load evenly. If you cut that down to one cable on say a 150watt gpu thats over 12 amps on say a 24 awg cable. I think 24 awg is rated at 13 amp.

Potential fire hazard. I do NOT recommend doing this.

was looking at 8 or 10awg wire..

Sorry I didn't read all that post. What are the ratings on that cable? Like 30AMP Cause that will be stiff as hell if its single core or you getting stranded?

If you want to be safe then you can say for like the 6 pin 3 12v that would be 36AMP for the single cable to offer the same protection. Depends how you want to deal with it really.

10ga 30-35-40 (60/75/90°)
8ga 40-45-50 (60/75/90°)

mainly id wanna re-grid the GPU cabling.. all the redundancy amplifies the clutter.
since most PSU use a 18ga multi-strand @ 3x a 14ga solid would be edge so a
10ga should easily carry the current.

Shit yeah I had a random cable that was 24 gauge in my draw here that must be floppy or something. I was posting while on CS.

Do you not think that its going to be a little unsightly having the loops bridging the pins at the gpu end?

i was thinking of a cap to cover the terminal and all that would be seen is the two
input leads. sleeve those two wires and done. no more flop, holds a shape,
and simple. 2 wires instead of 14...
