Good day , 

Can someone please tell me how much watts PSU should i get for  6 ++  rx vega 64  and possible upgrade for more cards on future ? 

should 2 PSU of 1600Watts each would do the job ? 

currently i have only one rx vega 64 undervolted running at 100-130 watts  ,  with a psu of 850w

Go to this PSU Calculator and input the maximum of 8 RX VEGA64 and the rest of the hardware in your computer: https://outervision.com/power-supply-calculator

This is will give you a general idea of how large of a PSU you might need.

NOTE: I inputted 8 Vega64 and 3700X CPU and one M.2 NVME Drive and 6 fans and one Blu-Ray drive and it said you need a Recommended 2645 Watts PSU.

Your will differ depending on what Hardware you input into the Calculator.

This PSU website mentioned you need a minimum PSU of 1100 Watts for 2 Air cooled Vega64 in Crossfire and PSU of 1500 with 2 Vega64 Liquid Cooled Edition.

One undervolted RX Vega 64 Liquid GPU die can pull 350-400W when gaming at 4K Ultra.
More power is required for the rest of the Graphics Card. 

You can see the recommended PSU for a system with a single RX Vega 64 reference card here. 

750 Watts.

hello there , mine is stocked . at wall outlet is drawing between 130-180 watts  , at mine program is saying that drawing between 100-130watts   , the current psu is 850 + if i will start adding cards on current psu do u think i will burn something ? 

Because im new at at this . lets say i have 10 cards of rx vega all undervolted at same frequency as the currently one . on watts etc 

if its drawing on wall output 180 watts , its not calculated 180 watss x how many cards i have ? lets say to be safe is drawing 250 wats each  x 10 cards  = 2500 watts ,  a 2 x 1600PSU would u think will keep the system sable 24/7 ?
