Hi,

Well, there are more questions about this power supply, so I hope you can solve some of them:

- The first one, the one of the title: All of PCIe ports of this power supply have the same voltage or power in wattios?
- I have connected some GPUs to some of these ports. All the cables have the same capacity of voltage, or I need to be careful about that, because if I connect one of them to a PCIe that offers more voltage, the cable can burn or something like that?
- I see that some of that cables or wires has at one extreme 8 pines, like (6 +2). I have to connect the 2 pines part? FOr what are them?
- There are other cables that are 8 pines (only 8, not separated). Why some GPUs needs this cable and others needs this 8-pin cable plus the 6+2 cable?

Excuse me for my ignorance, thank you for your answers. If you need more information, tell me.

Regards

I think this would be easier if you told us what you are trying to power with this PSU and we can tell if it will work.
But I'll try anyway...
All of the PCI-E connections on your PSU offer the same "power" at the connection, there isn't a boosted connection or anything like that. The available 12v power is shared between the connections.
The 8+2 cables can carry more power than the 6 pin cables, and GPUs have certain connections due to how much power they draw.
If you GPU has a 6+2 slot and a 6 pin slot it would be wise to connect both of them yes.

Thanks for your help and quick response. I wonder to know how much power pass through a PCIe port as maximum. Is there a standard? Thank you
