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...

The new PC might draw more idle power.

Intel's platform reached exceptional idle power consumption with their 4000 and 6000 SKUs. My 6600K with a 1070 drew less than 20 W, my AMD AM4 and AM5 systems are drawing 2 to 4 times that (including the GPU). However, they are way more efficient and powerful if you actually need the performance (and it's more fun).

I would recommend to optimise idle and standby power on your new computer as much as possible. Switch off standby USB power (saves up to 10 W of constant power draw), use S4 or even S5 states and set short times for display sleep and auto-standby. Idle and standby / switched off power consumption can save you a whole lot of money. Each one Watt reduction of constant power draw will save you 4€ annualy here in Germany. Running my AM5 platform 24/7 would cost around 250€ per year. That's 1/8 of the cost of the build.
