Daisy chain gpu cable

[ArronMay]

I've got the rx 6800 and a tx750m. Will I be fine powering the 6800 with a daisy chain cable? I've been looking around and people saying I need another seperate cable for it. Am I fine or nah?

Welcome to the forums!!!

 

Daisy chaining two cables will put extra load and amperage through a single PCIe cable from your PSU. Some people on the forum here will say nothing has happened to them with this but I'd advise otherwise. Use two separate PCIe power cables to power your 6800. It doesn't hurt anything other than having two PCIe cables running to your graphics card, which may not look as clean.  

 

You don't want to use one of those brown $1 store extension cables to run your household vacuum cleaner right?? You would overload the extension cable with too much amperage, causing the sheathing of the cable to melt.

Alright thanks for the answer. Do you know what PCIe power cables I should buy on amazon, all I keep seeing are short extension cables. I'm in the UK if that makes any difference.

I use the daisy chain method.  Works fine.  But if you want to buy a new set of cables, make sure they are made specifically for the model psu you are using, or you will have a really bad time.  The psu side of the cables have a very specific pinout.

Specifically for the TX750M? or any cables for corsair in general?

Check cablemod UK/EU

 

So you do not have any cables or what?

I'm not too familiar with that end of PCIe power cables as the power supplies I've bought have extra long cables. @miagisan is correct though about power supplies having a different pin out from the PSU side so buying the correct cables is a top priority so you don't send 12V through ground on your expensive graphics card.

I think ill just buy an RM750X since it comes with 4 cables and cancel the tx750m then. Thanks for the help.
