Hello,

I need some advice regarding a PSU for my future build:

- CPU: Ryzen 7950X

- Cooler: Arctic Liquid Freezer III 360 (3 included fans)

- RAM: 64 GB G.Skill 6000 MT/s

- GPU: hopefully RTX 5080 at a reasonable price

- Drives: two M.2 SSDs and two HDDs

- Case: Phanteks G500A (4 included fans)

• These are currently the lowest prices in my country for the following models:

Super Flower Leadex III Gold Up 850W (SF-850F14GE)      - 110 €

Super Flower Leadex III Gold Up 1000W (SF-1000F14GE)    - 134 €

Super Flower Leadex VII XG 850W Gold (SF-850F14XG)      - 137 €

Super Flower Leadex VII Pro 850W Platinum (SF-850F14XP) - 153 €

Super Flower Leadex VII XG 1000W Gold (SF-1000F14XG)    - 168 €

*The SF-1000F14XP is not in stock right now, I don't know when it will be available again. 😔 

*The Leadex III units are the new ATX 3.1 ones mentioned here:

• Some alternatives to Super Flower:

Corsair RM850e 850W Gold 2025 (CP-9020296-EU)    - 141 €

Thermaltake Toughpower GF3 850W Gold (PS-TPD-0850FNFAGE-4) - 144 €

Corsair RM850x 850W Gold (CP-9020270-EU) - 145 €

Thermaltake Toughpower GF3 1000W Gold (PS-TPD-1000FNFAGE-4) - 160 €

Cougar Polar 1050 Platinum 1050W (CGR-PR-1050)    - 161 €

Corsair RM1000e 1000W Gold 2025 (CP-9020297-EU)    - 174 €

• And some models with higher wattage just to show price comparison:

Thermaltake Toughpower GF3 1200W Gold (PS-TPD-1200FNFAGE-4) - 168 €

Cougar Polar 1200 Platinum 1200W (CG31PL120000P01)      - 184 €

Super Flower Leadex VII XG 1300W Gold (SF-1300F14XG) - 187 €

From my research it seems that 850W would be enough for this build, and more than 1000W starts to be overkill.

If so, which model from these listed above would be the ideal choice?

Thank you.
