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.

Balanced has no letter: it is a weighting preset, not a capability rubric. A grade answers “how well does this handle that job?” — price is never part of it. Relative Value puts the current market price back in.

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).
140 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.

FAQ
Why does Relative Value change when I choose another scenario?
Each scenario changes the weights applied to capability, price and the other published factors. The hardware facts stay fixed, but the value question changes, so its score and rank can change too.
Why can Amazon appear without a tracked price?
Amazon listing snapshots can participate in Value while fresh. We show Check on Amazon instead of its price; confirm the current price and availability at the store. When no current listing snapshot exists, Amazon is a search link only.
