Plug and play

Installed the Corsair RM850x into my build the same night, everything detected first time. PowerHouse SLS also updated my BIOS for free when I asked. Steady.

Good price for genuine stock

Box sealed, serial matched the warranty. Cheaper than the big chain stores. Will buy the rest of my parts here.

Legit local set

Was worried about parallel import but this one is local set with proper warranty card. WhatsApp reply also fast, they kept the unit for me until Saturday.
