Question CORSAIR CX-F Series CX550F RGB 550W for RTX4070?

genca · May 8, 2024

I can grab this psu for decent price rn, it will be paired with asus dual rtx4070 and probably ryzen 5 7600, 32gb ram, 2 1tb ssds? It will be used for 3d modelling and animation

For 20 bucks more i can grab seasonic focus gx550, but id like to avoid that as it is highly above my budget

If I were you I wouldn't look at 550W units, more like 650W or higher. Having head room just means you get to hold onto the PSU for longer.

Where are you located, what is your preferred site for purchase and how much have you set aside for your PSU's purchase?

Minimum PSU recommended for an RTX4070 is 650W.

80euros max, thats like 31.000ft

I thought i could get away with 550w, as 4070 can draw 200watts

Don't mess with PSU requirements. NVIDIA says 650W, so stick with that. There's headroom in there as a safety factor for sure but do you really want to bet the rest of your system? A cheap or under specc'd PSU can get VERY expensive VERY quickly.

An ATX3.0 unit with 12VHPWR connector is a much better choice for a RTX 4070. Raise your budget and get this Thermaltake GF A3 650w
