I shelled out just to be sure (bought cables with two ends though, since they're for some reason cheaper than single connector ones — makes cable management a bit messier). I haven't seen it to pull more than 200w so far though, although the only game I've been testing it with was Elden Ring which is admittedly not the most demanding one (even in 4k with everything maxed).

Is this really such a big of a concern? I just built a new system recently with 7900 XTX and Corsair RM850x as a PSU, and it came with only 2 PCIe cables with daisy-chain ends (ridiculous amount of SATAs though for some reason), so one of the connectors on the GPU is currently using that. Should I shell out for an extra cable? Corsair ones are ridiculously overpriced where I'm at, €23 for a single one.
