Doubt regarding making connections

Go to solution Solved by Guest,

Dude... You can go from the +12V on the 24-pin to a +12V to a PCIe connector.  It doesn't matter.

 

As long as you don't mix the voltages.

 

And make sure you have a multi-meter before you get started.

This my pinout for MWE gold 650 Coolermaster

 

I know that orange are 3.3v and needs to be connected to 24pin on mobo side. but my doubt is there are more oranges on psu side which 2 needs to be joined like

 

PSU has {7,812,16,17} at 3.3V

and mobo 24pin has {1,13,14,24}

 

What two on PSu side be connected to one of 1, 13 ,14,24?? similarly black(GRND) and

Psu cables are notoriously non standardized and can be subject to engineering stuff to the point that the general rule is to not use any cable but that which actually came with the PSU. I notice there are 24 pins mob side but 28 pins PSU side.  Implies some connections are not being used even though they are there. 

Not a pro, not even very good.  I’m just old and have time currently.  Assuming I know a lot about computers can be a mistake.

 

Life is like a bowl of chocolates: there are all these little crinkly paper cups everywhere.

Well if those are really all 3.3V or all GND (for the black ones) it wouldn't matter as they are in theory, all hooked up to the same rail internally.

 

What you could do, is use a multimeter and do a continuity test between the 3.3V pins on the PSU (while it's powered off of course) to find out if they are connected to each other.

My specific doubt is

3.3v orange on 24pin connector mobo side has 4 such pins {1,  13,  4,  24}
On psu side has  18pin psu side has 5 such pins {7 , 8, 12, 16,  17} any of two of 18 pin side should be joined with one of 24pin side.

Which two to be connected to that on 24pin side.(same doubt in case of black ground)

 And i guess i can connect red from 24pin to both 18 and 10 pin. As there are 4 on 10pin side and 2 on 18pin side.

Also,  Where did you find this drawing?  This is probably the best pinout drawing I've ever seen (because it shows the pins AND the connector shapes).

 

It seems to be from Cooler Master, under downloads for the MWE Gold (and probably other CM PSUs)

Cool.  It looks like they use the same connector/pinout as Corsair for the PCIe/EPS12V connector on the PSU.

 

I wonder what other PSUs use this same connector.  Would be nice to be able to tell people that you could use the same PCIe or EPS12V cables on brand X, Y, Z, etc.

But they did not mention any sense pins and double wire which is let down. You need to do that multimeter trick. took me a while to build to do my cables.

There are no sense wires on the PCIe or EPS12V.  The proposed sense wire is replaced with a ground.  The only double wires you would have is if the PCIe pigtails to a second connector.

My was question was regarding PSU to mobo 24pin. I found the way and finished the cables It looks like a charm now I guess(atleast for me).
