These are my specs:
PSU: Corsair RMx Shift Series RM750x
MoBo: ASUS TUF Gaming B650M-E wifi
CPU: Ryzen 7 9800x3D
AIO: Water Cooler MSI MAG Coreliquid M360
GPU: RTX 4070 Super
RAM: 2 x 32GB Kingston Fury Beast 6000MT/s
FAN: 4 Rise Mode Hex Turbine PWM
Nvme1: 1TB ADATA SX8200
Nvme2: 2TB WD Green SN350
SSD: 1GB Generic from AliExpress
HDDs: 2 x 1TB Seagate ST1000DM003

I used a calculator from Corsair and it recommend me a 650W supply. I got this one because it was on the Cultists Network High-Tier

I don't overclock and will never. I may upgrade for a better mid-range GPU in (2+ years) and a bigger SSD Nvme.

Was him right or full of BS?

Thank you!!
