So although a new graphics card might be the biggest consumer, each part adds up. So with the increasing TDPs, you have to consider a higher capacity power supply.

But with the rising power consumption of all these and rising costs, efficiency might be more important. So we bring you a range of options for you to pick from.


What are the Ryzen 7000 TDPs?

When it comes to looking at power supplies you want to know how much power you need. With one of the specifications of PSUs is how much power they can provide.

So to know how big of a power supply you need, you have to add up your components. So we first look at the TDPs of the new CPUs.

There we see 170W for the top two choices, Ryzen 9 7950X and 7900X. Whilst the lower two options, the Ryzen 7 7700X and Ryzen 5 7600X, have a rating of 105W.

Although in terms of AMDs spec, these tend to be the thermal design and not direct power consumption so it is likely higher than that.


Do I need a new power supply for Ryzen 7000?

If you already have a power supply to use then no you won’t need to upgrade it just for these CPUs. You only have to consider it if it’s not powerful enough.

The power connections are staying the same for motherboards and CPUs so no need to worry about that. You just have to make sure it can sustain the whole system and not cause shutdowns and issues.


What are power supply ratings?

When you’re comparing different power supplies, they will tend to have different 80 PLUS certifications. This is a test to provide the efficiency of the PSU.

It is important as one of its jobs is to convert the AC power in your house supply to DC for your computer. This produces heat and inefficiency means a loss and waste of energy that you still pay for.

So a quick rating will give you an idea of how well it will do its job.
