Need help with the new 3.0 ATX and 5.0 PCIe or older PSU. Im currently building a pc with RTX 3080 and Ryzen 5700x and plan to upgrade to a RTX 4080-4090 in 2-3 years and after that to the new 5-series. Also switch to AM5 in about 2-3 years or skip it completely.

So do I need a future proof PSU with the 3.0 ATX and 5.0 PCI-e so that I don't need a new psu when I eventually get a 4080 or 4090 and later the 5-series. I would like my psu to last the 5-10 years period.

Currently looking at non 3.0 ATX versions like: Asus ROG-STRIX-1000G or Corsair RM1000x, 80 PLUS Gold

And 3.0 versions like: be quiet! Pure Power 12 M or Corsair RM1000x, 80 PLUS Gold
 
pure power 12 M is not as good in terms of build quality as others you have listed .
if you want psu for future upgrades it is better to get atx 3.0 -
this way you don´t need a reduction to power new nvidia graphics cards .
for example phanteks AMP 2.0 is solid and doesn´t cost that much
MPG A1000G or thermaltake toughpower GF A3 are also solid options .
sligtly more expensive and even better would be asus strix aura .

Thanks for your reply. So basically im in a situation if I buy a 120-150$ PSU for my RTX 3080 (850W/1000W) or spend about a 100$ more for the 3.0 ATX for future builds and would pick a 1000W definately in that situation. Do you think 1000W 3.0ATX would be enough for 4 & 5 Series GPU:s ?

Currently looking at my stores stock selection, i'm looking at the following. The non 3.0 ATX is around 150-170$ and the 1000W 3.0 ATX are around 220-230$.

NON 3.0 ATX :
1. Asus ROG-STRIX-850G, 80 PLUS Gold
2.Asus ROG-STRIX-1000G, 80 Plus Gold

3.0 ATX:
1.Asus 1000W ROG STRIX Gold Aura Edition, ATX, 80 Plus Gold
2.Asus TUF Gaming 1000W ATX
3.MSI 1000W MPG A1000G
4.Thermaltake 1000W Toughpower GF3 - TT Premium Edition
