Seriously none of you guys even mentioned that the quality of a PSU isn't just about the number of watts it can give?
i did hint that the fsp unit is preferred as it is a top tier unit (which in my mind automatically translates to better quality). to add on, psu quality also does not depend on brand: corsair makes junk tier units while gigabyte does sell decent units.
the best way to determine quality of a psu is by searching up reviews of the specific psu u are looking at. and not just """reviews""" that build a system with it and says it power on ok, but reviews that actually teardown the psu and test various parameters of its power output like ripple, protections and voltage regulation. if u cant find reviews, then u can fall back on the psu tier list here:
https://cultists.network/140/psu-tier-list/a good rule of thumb is to not skimp on the psu. locally there are units that are priced quite cheaply that make good quality ones look like bad deals when looking at power output alone, but u cant really go wrong with psus in the $150-$250 bracket in terms of quality, warranty length and in some cases value.
