Performance and where it ranks
Two different questions, side by side. Performance compares what the hardware can do; Value compares what that capability costs at today’s price. A product can rank high on one and low on the other — that gap is the point.

What to check in your build
A case that takes ATX power supplies
The size is set by the case: ATX cases take ATX units, small cases take SFX (some also SFX-L).
180 mm of power-supply bay, plus room for the cables
Case makers list the longest power supply the bay takes; modular cables need extra space behind the unit.

What should I upgrade to from the Corsair RM1000x ATX 2.53?
For the same capability today, the closest current product is ASUS TUF Gaming 1000W Gold; for a meaningful step up, NZXT C1500 Platinum is the best Value among products at least 30% more capable.
