Hi there

I will be upgrading my system and I've been wondering if I will need to buy a new PSU aswell

I did some calculations online for PSU wattage and it seems like it won't be enough if I add up the TPD from the CPU cooler, but I really wanted some more experienced opinion here

My PSU is an EVGA 850W Gold Plus

The new specs are going to be:

MOBO: Asus Z790-E or similar
CPU: i7 13700k
CPU Cooler: DeepCool Assassin 4
RAM: 2x16GB DDR5
GPU: 4070 ti
1 NVMe
2 SSD's
1 HDD

No overclocking

Thanks in advance

Show us your calculations.

The video card is rated at 285 watts maximum as far as I can tell.

I've used Coolermaster website to do the calculations, which gave me around 700W, but they don't have an option to choose a CPU cooler
And from what I've seen on Amazon, DeepCool Assassin 4 will have a TDP up to 280W

No, but with that cooler and with any air cooler you will need to undervolt and further limit your CPU anyway. Best air coolers run fine up to 200 watt and your CPU can use 280 watt.

Air coolers don't use any power other than a very tiny bit for the fans.

I'm not clear on why the cooler is relevant to your choice of power supply.

So, I'm apparently misunderstanding.

What did Coolermaster say about the power used by your motherboard??

By your NVMe?

By your RAM?

By your CPU?

Piece by piece.

Or nothing but a total?

Damn... I guess you're right. How dumb of me hahaha.
Maybe the description of the CPU cooler is referring that it can deal with a CPU that draws up to 280W?
