Power consumption question

[matrixman]

Okay, 

 

I have a question. 

 

I am upgrading and I already have the parts coming in but I was just curious.

 

My current PC has

 

CPU: i5-4690s 

GPU: 980 ti Classified EVGA

Memory is 16gb ddr3

Storage: Samsung 200gb Sata SSD

1tb Seagate hdd 

 

Antec TRUE POWER 750w 7-9ish years old

 

 

My new pc is going to have 

 

CPU: R5 5600

GPU 6700xt

1tb nvme

16gb ddr4

Enermax REVOLUTION D.F. 2 850 W

 

The question is, which one will be more power efficient. Or draw more power. 

 

Using same peripherals intill I get more money to upgrade.

I think its going to draw almost the same power, but itll be much more efficient, a 750w psu could still be good four your new upgraded computer

 

I have an rx 7900 xtx and a i9-10900f running of a 700W psu..........

Your new PC will be much more efficient in terms of how much work it can do with the power it draws, but that draw will probably be about the same as your old one.

to answer what i suppose is the question,  no you should not use your ancient psu to save a few bucks...
