Is it necessary to supply power to the processor 8 pin + 8 pin on x570 master?

Question

Power Supply

Hello everyone, I ran into this question
. I'm buying a Ryzen 9 3900x and an X570 AORUS MASTER motherboard and I have a power supply from the current Thermaltake TR2 RX 1000W [TRX-1000M
]
PC CPU (x2 8 pin CPU)
But the old power supply does not have the necessary connectors, it only has 24 pin + 8 pin and 4 pin CPU
Is it necessary to think about replacing the PSU or is there enough power from the old PSU?
Thanks in advance!

Answer 1

two 8 pins per CPU

Your percent devours 105 watts of power at 12 volts - this will be a current of about 9 amperes. This current flows through 8 pins (if you use both connectors, they are probably in parallel there), or four, if you use only one.
My verdict: for 9 amps, 4 pins are enough (i.e. one connector), using both is unnecessary. BP has one - that's it and that's enough.
Adapters with Molex are highly undesirable, Molex is not designed for such a current, it will melt and someday this will lead to a short circuit.

Is it necessary to think about replacing the PSU or is there enough power from the old PSU in general?

Change a powerful kilowatt PSU due to the lack of a second 8-wire tail??? Do you have too much money?
If it is unbearable to use the second tail, then open the PSU and solder this tail directly to the board, without adapters, to the same points as the existing one.
