CPU has 2 ribbon connectors made up of 4 wires each. The top wire swaps over to the bottom

Comparing it to other cpu modular cables I have as spares top pins always go to top and bottom to bottom. https://imgur.com/a/4L2TJHr
Power supply is an antec neo 850w bought brand new
Should I risk running it and just plug it in or wait for tomorrow to check with a store who probably has no clue either?
no, the spares are from a super flower, worse case I will put a test plug in and get the multi meter out. Looking at some PSU pin outs it seems weird that they would invert the wires in the psu and seems it would be easy to put the wrong ribbon in one of the connectors.
Use the cables that came with the PSU and not cables that came from elsewhere (unless custom built for this build from a reputable custom cabler).
On the PSU end the pinouts are unique to each brand, on the motherboard/GPU/device end they are all standard.
Using cables from an old install is a quick way to fry your components.
Its thrown me off since the vga cables are flat, they use cable ties to try and keep the cables all flat which makes sense since its their cheaper psu with no sleeving. The cpu is also cable tied but has the swap which I thought was a kink which brought my attention to it.
The pinouts can be wrong even for the same brand of psu but different product lines, let alone 2 different brands.
ALWAYS use the cables that came with the psu. You would have to be an idiot not to.
Correct, Corsair's site below details model/cable compatibility as an example:
Check with multimeter, 12V EPS cables should be +12V across the top 4 pins and ground for the bottom 4 pins.

If you know how to use a multimeter, then definitely do tests and don't trust a retail store employee or anyone online - find out yourself.
Worst case for a 12v short direct to ground would be blowing up your mobo + CPU, but it might just trip the internal PSU circuit breaker. You'll be responsible regardless of what advice anyone else gives you…
I put a multi meter on it last night, power is on the bottom connector which is why the ribbon cable twists over. My post made it sound like I was going to use a spare cpu cable, I was just checking it for reference.
thanks all
Are both cables from the same model of power supply? There is a reason that cables from model different power supplies are not always interchangeable.
