Hello,
I'm about to do custom cables for the OCZ ZX 1000 and the Corsair RM1000i and I just want to cross check a few things.
I did my pinout diagram for the OCZ ZX 1000 based on the following information from Overclock.net 's famous repository of power supply pin outs.
OCZ ZX 850w PSU side Pinout
MB Side ATX-PSU Side ATX
1(+3.3v)-5(+3.3v)
2(+3.3v)-17(+3.3v)
3(GND)-8(GND)
4(+5v)-14(+5v)
5(GND)-6(GND)
6(+5v)-13(+5v)
7(GND)-10(GND)
8(PG)-21(PG)-grey wire
9(+5 VSB )-18(+5 VSB )-purple wire
10(+12v)-12(+12v)
11(+12v)-24(+12v)
12(+3.3v)-4(+3.3v)
13(+3.3v)-16(+3.3v)-double wire with brown to 15(psu side)
14(-12v)-19(-12v)-blue wire
15(GND)-23(GND)
16(PS-ON)-20(PS-ON)-green wire
17(GND)-7(GND)
18(GND)-11(GND)
19(GND)-22(GND)
20(Not Used)xxxxxxxxxxxxx15(brown single wire connected with orange wire to 13 on MB side)
21(+5v)-3(+5v)
22(+5v)-2(+5v)
23(+5v)-1(+5v)
24(GND)-9(GND)
1. Is it fair to assume that the OCZ ZX 1000 uses the same pinout as the OCZ ZX 850 ? Can any one confirm ?
Here is the diagram that I traced using that information.
2. Can someone back check that diagram, just to make sure I understood correctly ? (especially for the 13th and 20th pin on the motherboard side)
From what I understood, pin 20 on the motherboard side is not used. However, looking at the standard 24 pin pcie connector, I see that pin 20 should be -5V. I feel there is a problem here.
3. Is there a problem with pin 20 on the motherboard side ?
Finally, for the Corsair RM1000i, I searched for a pinout and only found the AX1200i's pinout diagram.
4. Is that the same pinout as the RM1000i ?
5. What does the "S" on the 3.3V pins refer to ?
6. I don't see the -5V pin, as shown on the standard 24pin connector referred earlier. How is that ?
7.And finally, the 6+2pin pcie connectors are shown as having 4x 12V pins and 4 grounds. The standard connector referred earlier has 3x 12V and 5 grounds. Do I make a double wire from a ground on the PSU side to the 5th ground on the GPU side and leave the extra 12V pin on the PSU side unused ?
Thanks for the input.
