450w power supply for rtx 3060

[Ryzxnn]

So I am thinking of getting an RTX 3060 and I really do not want to get another power supply. My current one is a Corsair CX450M. Will I need to upgrade say to a 600W or 550W or can I run it smoothly with my existing one?

A 550W would probably be a good investment, but it depends on your cpu

most likely it'll be fine (depending on the rest of your PC)

 

you can always upgrade if it's not

I have a 1700x

I would recommend upgrading to a 550w then

Friend of mine is running a GTX 1080 off a CX450, that's combined with a Ryzen 5 3600.

With about 200 watts for the 3060 and 115 or so for the 1700X, give or take 100 watts more for the rest of the system, you would be within the power budget. Personally I would trust the CX450 because they have proven to be able to handle transient loads pretty well and your setup isn't terribly demanding. But you could upgrade if you like, especially if you plan on upgrading to a more demanding CPU and perhaps getting a 3070 or something in the future.

Well if I were to upgrade to a newer Ryzen then that would mean even less TDP, and I probably won't get a 3070.

A Ryzen 5 5600X or 3600 would be more mild, but a 5800X might be boosting more aggressively. I've seen some measurements that put them in the 115-130 watt range. The 2700X for example was also a slightly more power hungy chip.

 

Of course this depends on your motherboard too. If you're running a cheapo A320 motherboard or a bare VRM board there's a good chance the 1700X isn't reaching its full capacity.

I will probably upgrade later if I really need to, but seeing how Windows 11 will run fine on the 1700x, for the future I probably won't upgrade.
