Will my AX860i be enough for RTX 4090?

[zaselim]

Hello, How are you?

My current system is 

I7 6700k

Asus Maximus VIII Hero

Corsair Vengeance LPX 3200mhx DDR-4 16x4= 64Gb Memory

Cooler master Liquid ML360R

Samsung 870 Evo 500Gb x2

Adata XPG spectrix R 2Tb

Seagate HDD 7200 rmp x 4

Corsair AX8600i

I will be upgrading my System throughout this year and I am getting Asus Tuf RTX 4090 OC first so i wanted to ask, as the tittle suggest, will AX860i be enough for the time being.

I will be upgrading everything to I9 13900k, Asus Rog Strix Z790 E-Gaming, Corsair Vengeance DDR-5 5600mhz x4, Corsair AX1600i and the first thing i will be updating after the card will be your AX1600i PSU in 3 to 4 months. So in the mean time can i use RTX 4090 with AX860i PSU? 

I'll really appreciate the help, thanks.

It should be enough. Like most of the 4090s, it has a 450W power limit. The 6700K might at most run over 100W. So even if you allow another 100W for system resources, you are still very reasonable at 650/860W. I don’t think you can make 650W anyway. My 4080 is a 450W gpu and is paired with an overclocked 13900K and my real life loads peak in 550-600W range with a lot an extra gear and lights. 
 

You will need a multi-PCi-e 8 pin to 12VHWPR conversion cable. Don’t know if that gpu has one in the box.

Thanks for replying, My PSU doesn't have 12VHWPR conversion cable, GPU has that in-box nvidia's 4x8pin connectors to 12+4 16pin socket. I was looking into this 2x8pin to 16pin conversion cable https://www.bestbuy.ca/en-ca/product/corsair-600w-pcie-5-0-psu-power-cable-cp-8920284-black/16578294 but i don't know if my PSU is compatible with it.

Do you have any ideas if AX860i is compatible with this cable or not?

Thanks.

from the table, this AXi is type 3 PSU so it will work, since these 8 pin sockets on the PSU are the same pinout between type 3 and 4.

It will also be compatible with the AX1600i which is type 4.
