Is it safe to use modular cables from another PSU?

post #1 of 9
Thread Starter 
I need another PCI-E connection on my PC P&C Silencer Mk III 600W, but the PSU came with a second 8 Pin EPS modular cable instead of an additional PCI-E cable.

Would it be safe to use modular cables from another PSU, such as the Corsair TX750M? It appears that the PCI-Express modular connections are the same on the Corsair and the PC P&C (both use 8 pin connectors).

yes cables are cables -- so long as the connectors are the same and lead to the same kinda connector on the other end -- like you dont wanna be connecting cable with a PCI-E connector on one end to the aux 12v line of course.

My PSU is a single rail Seasonic based design. The two modular connectors on the right side seem to be identical. However, my PSU came with 1 PCI-E modular cable and 1 EPS 8 pin modular cable. What I want to do is use both of those modular connectors for PCI-E cables. Would that be a safe thing to do if I use a PCIE cable from a Corsair PSU?

As long as the pinout is the same, yes.

I read that it's NOT okay. I don't have the source right now but even my AX850 wires says "only for AX650, AX750, AX850".

Probably just said to encourage the user to buy more cables specific for the model. Basically, they want your monies.


But best to play it safe when it comes to this kinda thing.

On Corsair's PSUs, it seems like the pinouts for the 4+4 pin EPS and 6+2 pin PCI-E cables are identical as well, since it says "PCI-E & CPU" above that block of 8 connectors on the bottom right.

Keep in mind that the AX1200 is not a Seasonic Re-brand and has different cables than the lower wattage AX series PSUs (which are Seasonics).

Yeah, that's true. The Corsair PSU I'm considering using the cables from is a TX750M, which is a CWT unit. But the connectors look to be identical on the TX750M and on my PC P&C 600W (see OP for pics).
