Nothing is future proof, everything dies sooner or later. I like Cosair PSU, from thier first HX-520W/620W, TX, HX650, AX-850, RM850x, RM650x and the laltest RM850x 2021; Also Seasonic Evo and X-460; Antec Neo-HE, TruePower series and many others brands/models.
Most of them die after their 5 warranty period, even the Corsairs. Both HX 1st gen malfunction just before their 5 years warranty, Convergent was kind enough to replace them with HX-650 with new 5 years, need to top-up though; The AX850 also die just before before its 7 years, replaced with RM850x.
My experience is PSU will die faster in hotter enviroment, if the casing do not have great air flow. But I would rather buy a new PSU every 5/7 years than to endure noise everyday.
Eventhough almost every--except RMx--for now--Corsair PSU models die on me, I would still recommend them, atleast they lasted more than 4/6 years. If you venture enough, Amazon SG was selling RM850x 2021 for S$125 last week and it arrived today. Note that, Convergent will not warrant them and shipping/RMA 2~3 kg PSU oversea is gonna cost you. With 2/3 price of local unit, if it works for 5 years, I'd be happy.
