PCIE Cable for Corsair, 65CM Male to Male 8 Pin to 6+2 Pin GPU Power Cable for Thermaltake, ARESGAME Modular Power Supply (25'') (Black 18AWG)

Can confirm this works well with a Corsair RM850e power supply and an RTX 3090 ROG Strix GPU. Cables are a little more flimsy than the stock cables, so the gauge may be slightly less. That being said, they don't get warm to the touch so I'm not worried about them in the long-run. I can definitely recommend these!

I'm using these with Nvidia RTX 3090 GPUs and they are working fine.The PCIe outputs are functionally the same, even though the pins come from different wires than the Corsair HX1500i cables.I used a multimeter and continuity testing to verify, as I didn't want to fry a 3090. Here's the diagram, showing the ground ("G") and +12V pins for both the Corsair and Certusfun cables. Even though they come from different wires, the pinout achieves the same ground and +12V on all the same output pins.Cable thickness is good (looks like 14GA, and not the 16GA of some other cables) and same size as the original Corsair cables. I have no doubt they would deliver adequate current to the GPUs.

Incredibly tight fit. So tight, it may seem you’re going to break the connector, because it doesn’t go all the way in. You know what though? It works, and it stays in, and I’ve been over-clocking ever since.

I mean, it's a cable. Solid build and cable quality, good value for the cost, fits well into my power supply.It's a cable, it works; hard to mess up.

Like another reviewer mentioned, there is no gap between 2 of the PSU facing connectors on the cable. Making it impossible to fit.Listing description specifically states this cable is compatible with my Corsair RM 750X. The list of incompatible devices on the description gives no indication this cable would be incompatible with my PSU.No wonder why the product page has a is warning label about high return rates on this item. The description misleads people into thinking it is compatible with their power supply, when that is clearly not. This needs to be updated.In theory, you could take a slim hot knife and create the gap where it is needed.But there are 2 problems with that:1. You will no longer be able to return the item.2. If the pin layout is different in any other ways, it will not work and could potentially break your PC equipment.The cable sent is also not missing a metal piece in one of the little squares like in the OEM plugs. This shouldn't cause any problems with fit, but depending on the layout of the pins and if this extra pin terminates at the other end, it is difficult to say if this would cause issues assuming the main issue with the gap is fixed.

Good price for what I needed

I bought 3 of these for my RX 7900 XTX running off a Corsair CM850X psu. They were all pinned correctly and it's running perfectly. Corsair offers these for $30 or you can buy them for $10 each here. No brainer to me.

I have a PSU with a port for PCI 6 pin expansion but didn’t have the cable. Got this and it felt solid at the wire and connector level. No issues or complaints with this so far, and have been running it on a high power GTX 1080ti gpu.
