PSU Connectors?

[venomx]

Currently and in the future do most GPUs use 8 pin or 16 pin connectors ?

Im asking because currently my RX 580 only uses 8 pin but in future i may need 16



If you see in the picture my PSU does support 16pin however it would be very difficult without bending cables drastically...

It would be 8 + 6 or 8 + 8.

Not 16 in one connector.

Most are 8+8 these days at least on the higher end cards not sure about the 580 probably 6+8.

Either way its better to have a separate power rail for that i.e. a separate cable for each, if available.

I wouldn't say most are 8 + 8. It just depends.

I'm guessing at the question here, but that cable is designed to feed one GPU, so can be bent to fit without issue.

ah yeah I see the question now. Ideally you'd have different rails supplying each input to the GPU.

Have you not got another 6/8 pin connector coming from your PSU? Most recent ones have had that for years

My 580 only has 1x8 pin connector on it.
Had a look in my case and there are no more 8 pin connectors

Regarding the photo I posted do you guys think it would be possible to use both of them cables or not ( If i was to buy a more powerful GPU in future ) ? Like I said i'd have to really bend them to get both to fit at the same time

My RX580 only uses 1x8 pin so thats fine, but my concern is that some use 2x8 pin which would be really difficult to bend both cables round

Come to think of it, I only have a 500w PSU so 2x8pin GPUs would require more power right ?

I've had a quick check of some upgrades from the RX580 and most require 8pin only anyway

How does my RX580 compare to most other GPUs for 1080 gaming ?

I think for us to properly advise you we'd need to know what PSU you have

The cable should be able to bend fine if you bend it at the unsleeved section in the middle. It should be able to bend/fold over so that both connectors can be positioned next to each other.

 

[3t3P]

you could warm it with a hairdryer or low heat in the oven before bending, only 50 degrees or something for five mins

I thought that using one GPU cable with 2 8pin on them was bad practice??

I use two seperate cables for my 8+8 for my GPU.

Try the Power Supplies subforum instead you'd get better responses in there.

Agree. Can't say I've heard of that brand.

Separate cables and or rails generally best but that's not to say that if a PSU can handle it on one then why not if it's within rated spec.

Sorry double post. Is it a coolermaster PSU?

If so per the product manual you will have X2 PCI-e 6(+2) pin cables. Did you look for the second one?
Unless they mean both your connectors are on one cable as in your pic, they must intend for it to be used!

Your 12v rail capability is 38A. While it's been a while I've had to think rail specs that strikes me as a fairly decent number and the PSU is from a reputable brand I should think it would be fine.

Others might chime in.
