Well, I am seeing $30 difference so it may depend on your budget and availability.

But if me, I would likely go for the Corsair. I am not a huge fan of Corsair PSUs but their RM series have been reliable. That said, I choose it because it is ATX 3.1 and the others are still 3.0. That may not mean anything today, but a year or two down the road, it might.

I've had 3 rm750x and they all performed well. No complaints. Can't say anything about the others.

As I mentioned, I could get all three for the exact same price, but based on reviews, reports and whatnot, they still differ: for example the Corsair one is "only" rated as Gold from Cybenetics, because the efficiency on high/above room temperature is not enough to justify a PLATINUM rating, while the other two are doing okay on that part (but their overall performance is lower compared to RMX)

Thank you for the feedback!

I think one of us is confused (I am not ruling out that being me).

The Corsair is marketed as being Gold certified so there is no reason to suggest it would justify Platinum rating.

Note the requirement for 80 PLUS certification is 87 to 90% efficiency while Cybenetics Gold is 87 to 89%. That single percentage point is insignificant in this comparison.

If all 3 are the same price where you live, then for sure, the Corsair is the one I would get.

The Pure Power 12 M is "speculated to be high end tier" since it has no professional reviews. i'd pick the Corsair since it's a brand new platform and the only ATX 3.1 Unit.

12 M is HEC built

Hello, I'm having problem deciding which PSU I should choose between these three:
if it's the Corsair RM750x ATX 3.1 its a no brainer (the 3.1 has the knob for the fan control)
the previous model was excellent but not ATX 3.X spec
Core Reactor II is also very well built (also made by CWT like the RMx) but Ive heard some complaints about customer support. Right now Adata has hard to beat prices in NA for PSU.
Pure power 12 M is fine, well built for HEC but at equal prices i would go for the other two. I would use the Pure Power no problem if I got it at a discount.
