Check the depth before you order

At 180mm deep this is a long power supply. The ATX reference depth is 140mm and most cases quote a limit between 160 and 200mm. 180mm leaves very little room for the cable bend behind the unit, which is where tight installations actually fail rather than at the stated limit. Measure from the rear panel to the front of the PSU shroud, and subtract at least 40mm for cables.

Sizing honestly

1650W is more than almost any single card gaming build will ever draw. It makes sense for a workstation with two high draw cards, for a machine that will be upgraded into that territory, or where the 230V Indian mains lets the unit run comfortably below its peak. For a single card gaming system, 1000W or 1200W is the sensible bracket and costs considerably less.
