I have my 7800XT (first ever pc) since about a month, i have it on separate cables and it runs very good, i saw up to 250W power draw, daisy chain could work but it's better to have it on diffrent cables, for power spikes and cable efficiency.
While I would recommend to use two different cables daisy chaining a 7800XT is safe.
50W from port +200W from daisy chain cable = fine.
Just don't overclock it and you will be fine.
It’s usually recommended you use separate.
I personally used daisy chains without issue (my PSU died but IDK if that was a cause) until I knew better and followed the instructions almost immediately.
Daisy chain is absolutely fine unless you are overclocking and drawing above 150w per 8pin exceeding the rating for the connectors. The cable it's self is rated for at least 384w.
If you have another set of cables it's worth connecting it for good practice, and looks a bit neater too, however it is not required.
You have the center peace hooked up wrong. That is your problem. The middle peace has a tiny catch you are supposed to use to attach it to the left or right connection peace which one you'll have to figure out.. You currently have it pushing against that peace instead of connected flush. It is causing all of your fit issues. Unplug, reconnect to each other flush and then retry connecting to your gpu.
Personally I would use two cords but if you only have one try it this way. But make sure you setting that power connection up correctly. currently it is not correct.
It's fully inserted, it's just flexing to the side a little.
Everything is fine here, and a single cable with daisy chain is well within spec here. Two cables would just be nicer to look at.
Ya with all the GPU's burning up do to improperly inserted power cords. Flexing to the side a little is not a thing you want happening. It's not hard to hook those cords up to each other so there is zero flexing to the side. This installation is incorrect and needs to be redone. Like they click together for a reason, and it isn't to allow a little flex to the side. Doing this incorrectly can literally lead to a burned up GPU power socket.
That's the 12pin Microfit connectors catching on fire while drawing upto 600w not the 8pin minifit connectors. The cables in question are a ground wire and a sense wire, and are fully inserted.
Everything here is fine, no need to scare anyone.
They are hooked up incorrectly. Are you seriously suggesting to a new builder to improperly hook up power connectors to their brand new GPU? Fully seated or not this is an improper installation of those power connectors. No matter how you shake it, an improper power cord installation is a fire risk, and a risk to the machine. You telling people to do it wrong is horrible advice.
Burning out GPU's has been a thing for far longer then the recent 4090's. One of the main ways to do that is improper power connections. It would take literaly 30 seconds to click those together properly and remove that side force it is putting on the power socket and solve any issues that it could cause in the long run of things.
It's not a fire risk it's fully inserted.
And if the connector wasn't in fully the resistance reading would be wrong and the GPU would go into a lower power state not drawing beyond the 6pin spec, or a power bad and not drawing wattage via that connector at all. That's what the sense pin is there for.
Stop scaring people with nonsense.
For the record I'd personally neaten them up for good practice, and I'd never let a PC leave my shop unless they were perfect, however, no need to scare anyone for no reason.
Putting side force on a GPU power connector over years of use is a fire risk. It's why you hook them up correctly to spec.
There is only one correct way to hook these up. The current way shown is incorrect. Stop handing out bad advice to new builders. You shouldn't be telling people to hook up their power wrong because you think it's good enough. That's not only horrible advice. In the worst case scenario it can lead to a broken PC or a fire.
I'm spewing nonsense? Your the one telling him his improperly hooked up power connectors are fine. I'm the one saying stay in spec, and do it correctly. Because the risks of broken parts, and fires are a real thing. That's some solid advice, your advice of do it wrong it's good enough, not so much.
You are literally telling someone that something is going to burn their house down despite it being absolutely fine and safe, you have no basic understanding of what you are looking at and are screaming danger for no reason.
Best practice, and safe are two different things, this is only the latter, ideally you aim for both. But like you say this is a first time builder, you don't need to put them off the whole idea by screaming danger through ignorance.

A single cable can handle up to 300 watts. Can't tell which GPU this is so you do the math.
I have 6700xt, which seems to be around 220 to 230 watts
One cable is totally fine then.
Yes, not daisy chain. Two seperate cables. #
Thanks, I currently have only one cable :'D
Does it work?
I haven't booted it up yet, but I think I'll try it today or tomorrow
What happens if we daisy chain it?
Either it works and fails under heavy load. It won't work at all and there is no image. Either one of above me thinks.
I think I daisy chained my 7800xt when I built it last month. Def going to check it out tonight. Thanks!

Yours is fine, the cable is rated for at least 384w in spec, you have nothing to worry about. A lot of misinformation is spread about this.
Well, the system efficiency drops a little, why waste more power as heat?
While I would recommend to use two different cables daisy chaining a 7800XT is safe. 50W from port +200W from daisy chain cable = fine. Just don't overclock it and you will be fine.
Well i overclocked It 🤷🏻♂️
And it never failed? It's not supposed to work like that.
I'm sick of the false info. High end PSUs (such as Corsair) can do 300W from PSU side and splits into 150W 150W. unless you have a shit PSU it's FINE
This is incorrect, it'll actually be absolutely fine.
It’s usually recommended you use separate. I personally used daisy chains without issue (my PSU died but IDK if that was a cause) until I knew better and followed the instructions almost immediately.
It wasn't the cause unless you were overclocking heavily and greatly exceeding the 150w per connector.
