Power Supply Question.

[wade7575]

I'm looking at getting an 850 Watt Power Supply for an upcoming build and I don't care if it has a PCI-e 5.0 cable because I won't be running a graphics card that needs that the new PCI-e 5.0.

I seen people on other forums saying stuff about that you ca get Power Supply's that are wired differently at the pin's that go to the motherboard,but the only thing I ever heard about different wiring was the EVGA debacle where PSU's wee sent out wired wrong.

I read in this link to Corsair that there's some change in their type 3 to type 4 where they say something about a pin out closer to the top of the article.

I haven't read anything where I have seen stuff like this PSU is only compatible with this motherboard or anything like,is there a change I'm not aware of.

I can get a Seasonic Focus 850 right now in Canada for 129.99 and it's on sale and everyone else is charging 180.00 for it.

Not sure what the first part of this post was about, but the seasonic 850w is a decent deal on a quality unit. That psu will work with whatever you get.

Some guys and I forget where I read it and I can't find it are claiming that some Power Supply's come wired differently at the end of the plug's that go into the mobo and PCI-e stuff and so on that plug into the mobo and video cards.

I know that Corsair told a friend of mine via chat that with their type 3 4 and 5 cables they are wired differently depending on model at the Power Supply itself but the at the ends that go into the mobo and video cards.

I was just wondering because I have hear of the ends being wired differently that go into the mobo itself and video cards because then you have 2 or 3 different standards for the same 24 pin connector and people would be frying their mobo's if they just grabbed any old power supply if they were wired differently at the ends that go into the mobo and video cards.

So what I'm wanting to know is there any truth to what I heard about some power supply's being wired differently at the ends of the cables that go into the mobo and video cards that you need to watch out for.

The plugs that go into the power supplies are/can be different between brands and even between models of the same brand. The ones that go into devices are standardized. The cables from an EVGA power supply won't work in a Corsair or seasonic one for example

I don't think it matters as long as your PSU works fine. Nearly every brand has different plugs/connectors on the PSU side. It can be a problem only if you want to replace any cable, except for Corsair and maybe 1-2 other brands. Unless you want a modded PC with custom cables, it doesn't matter.

I got looking at the manual for the X670E Creator mobo from ASUS because I wanted to see a few thing's and I have never needed to use the 6 pin socket for extra power for the PCI slot to give the graphics card more power if needed.

Is the extra 6 pin found on many motherboards or just on certain models,I know in the ASUS manual it talks about if using 2 graphic's cards.

If you buy a new PSU the cables will be right. You don't need to worry about it unless you are buying aftermarket cables, like custom ones for example.

For pcie power as you stated along with fast charging capability. It literally says that on the page you showed us at the bottom. Are you using multiple gpus? Want/need 60W fast charging out of your pc?? If no, then don't use it. Optional.

Like everyone said about the cables... when you buy a psu, they are right for the psu. Motherboard side is standardized. You don't need to worry about mismatching unless you're buying second hand cables.

I just wasn't sure how much that 6 pin socket was used on motherboard is all.

Thanks for all the help and clearing that stuff up guys.

It's used as much as you want, or not all.

It's plugged in on my board for charging purposes... though, I think the 27W without it is enough to super fast-charge my phone (Samsung S22+, 25W) anyway. So maybe if you want to power/charge laptops off your PC. I never found it to be useful, but, perhaps you can.
