Is it enough wattage?

[cheese2drippyYT]

I have an rtx 3070 be a ryzen 5 4500 with 16 gb of ddr4 ram and I need a new power supply so that I have the right connectors for my gpu and I’m not too sure if 550w is enough as that’s the only one I can find within my price range.
I also know you aren’t supposed to cheap out on your psu or whatever just wondering if it’s enough

It should be fine.

I would honestly go higher.
The 550w would probably be enough but it'd be cutting it a tiny bit close and PSUs are generally something that are annoying to replace so it's advantageous to get one that is better than what you necessarily need, particularly if you plan to upgrade sometime within the 5-7 years.

needs an update but we know the watt usage of each gpu for rtx 3xxx or 4xxx

rtx 2080 ti "250W" is roughly like a rtx 4070 super "220W" in terms of wattage...

psu brand/model?

for gpus, do not use the chained/shared connectors

pci-e 6pin, only requires 2x 12v power pins, 75w
pci-e 6+2pin, requires all 3x 12v power pins and thicker cables, 150w

they are chained to use 2x 6pin , but not good enough for 2x 6+2pin

550W would be fine, 4500 doesn't use that much power and the 3070 is a 220-250W GPU

I’m only putting the 3070 into my build temporarily as I’m planning to build a new pc I just wanted to buy the 3070 used and I saw a good price and I thought that I may as well just put in in my pc for the time being
