As per CCC this is the cheapest this power supply has been going back to ~June 2024. Next lowest price was like $135 October 2024. Going to have a very hard time finding a platinum rated SFX power supply for less than $150. There was a Cooler Master V850 Gold SFX for $125 around Black Friday. This is better rated Platinum and compared to Corsair 850w Platinum pricing (~$180 and rarely on sale) this is a great deal for when the insanity on new components pricing finally subsides or for upgrading an existing system
