Question Is the MSI MPG A1000G PCIE 5.0 1000W PSU okay for this build ?

[Zaselim]

Hello everyone,
So I am building a PC this month and the parts will be:

I9 13900k
Asus Rog Strix Z790 E-Gaming
Asus Rog Strix RTX 4090 OC or Asus Tuf RTX 4090 OC (most probably I'll go with Tuf OC because Rog Strix OC is in back order)
Corsair Vengeance DDR5-5600 RGB 32x4= 128Gb (Dominator is not available and import costs double the price after tax/customs)
Samsung 990 Pro 2Tb x2
WD Black SN850X M.2 4Tb
Seagate Iron wolf pro 7200rpm 256Mb Cache 18Tb
(and I'll be adding my old SSDs (1x m.2, 2x Samsung 870 Evo, and 4 HDDs)
Cooler Master Liquid ML360R (in my current build which i bought last year in August)

Now I originally wanted (and still want) MSI MEG Ai1300P (Platinum) PSU but it is not available and has no date of availability, even the MEG Ai1000P is not available.
But the MPG A1000G (Gold) is available and MSI is the only ATX 3.0 PCI 5.0 PSU brand available here.
So will the MSI MPG A1000G be fine with my build or should I wait until MEG Ai1300P becomes available?

Also how's the Zotac Gaming RTX 4090 AMP Extreme Ario compared to Asus Tuf OC? As it is also easily available and my only reason for choosing Asus is because of 2 HDMI ports?
I'll really appreciate the help, thanks.

For RTX 4090, minimum, i'd look towards 1200W PSU, while 1600W PSU would be preferred. E.g any of these three 1.6kW "kings",

1000W PSU is too little for RTX 4090. RTX 4090 is rated as 450W GPU but with 4-way 12VHPWR adapter, can easily pull 600W. And if you add in transient power spikes, which increase GPU power draw even further, to ~900W, you do not have anything left over for the rest of your build. Hence minimum 1.2kW PSU, while 1.6kW PSU is better.

What are GPU transient power spikes? A video to watch:

A 1000w ATX3.0 PSU can handle 20ms spikes up to 2000w without shutting off. The MSI A1000G ATX3.0 should be fine.

Is it any reason ur using ASUS stuff so much?

The way ASUS have treated their customers in the AMD AM5 fiasco id be embarrassed to go near any of their products whatever they are.

They r a scumbag of a company.
