Question Need help with a PSU selection for a 4090 and I9 build

[Bladeriderr5]

Hi All,
I am in the UK and speccing a gaming/software dev PC as per below:

CPU: Intel Core i9-13900KS 3 GHz 24-Core Processor with Contact Frame Upgrade
CPU Cooler: EK cooler 360mm RGB Nucleus
PSU: ???
*Motherboard: MSI MEG Z790 GODLIKE EATX LGA1700 Motherboard
Memory: Corsair Dominator RGB Black 64GB 6800MHz DDR5 Memory Kit
Storage: Seagate FireCuda 530 4 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
Storage: Seagate FireCuda 530 4 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive
*Storage: Seagate FireCuda 530 2 TB M.2-2280 PCIe 4.0 X4 NVME Solid State Drive (for virtual machines)
*Storage: Crucial MX70
*Video Card: MSI Suprim X GeForce RTX 4090 24 GB Video Card
Thermal paste: Thermal Grizzly Kryonaut Pro-Grade Thermal Compound
Fans: 15x NF-A12x25 PWM
Accessories: Lian-Li strimer cable(s) for 24-pin and 12vhpwr
Case: 7000d

However, I am struggling to choose a good PSU. I was keen on the Seasonic but the Prime PX and TX are to be released in summer with full ATX 3.0 compliance. There is the MSI Meg @ 1300w, but the Seasonics seem to be the better products.

What other recommendations are there and for this sort of spec, what watts should I be looking at?

Thanks

This is what I run with my 7950x3D/4090 rig.

EVGA Supernova GT 1300W

I've used EVGA PSUs for years with no issue.
