Be sure to supply power to the processor 8 pin + 8 pin x570 master?

Hi all, faced with such a question

Buy Ryzen 9 3900x and motherboard X570 AORUS MASTER and a PSU from current PC Thermaltake TR2 RX 1000W [TRX-1000M]

Advice on nutrition

Motherboard requests the food: the Main 24 pin + two 8-pin CPU (x2 8 pin CPU)
But the old power supply has the necessary connectors, he only has 24 pin + 8 pin and 4 pin CPU
Definitely need to think about replacing the PSU or overall enough power from the old power supply?
Thanks in advance!

two 8 pin CPU
Your percent is eating for 12 volts wattage 105 watt - it will be a current of about 9 amps. This current goes through 8 contacts (if you use both connectors, they're probably in parallel), or four if you use only one.
My verdict: for 9 amps enough 4 contacts (i.e. one connector), use both too. BP has one - that's it and enough.
Adapter with Molex highly undesirable, Molex is not designed for this current, it will podplavleniya and someday this will lead to a short circuit.

To change powerful kilowatt PSU for lack of a second 8-wire tail??? You have that money surplus?
If it is unbearable to use a second tail, then open the PSU and solder the tail directly to the Board, without adapters, on the same terms that are available.

Sometimes enough.
Buy an adapter from Molex to 4pin, it should pull up.
