Hi I recently found a Corsair hx1000 used for 90€. He'd doesn't have a receipt but since it was released in 2017 it still has 7 years left on the warranty he doesn't have indicating that it should hold for a long time. Is this a suspiciously good Price and should I avoid buying it without warranty?

Edit: he is also verified with digital I'd in the sight so he is most likely not a scammer because then they'd instantly know who he is.
