Which one did they send you?

You shouldn't be looking at a brand and their advertised wattage alone, more so it's internal construct based off of reviews by reputable folks.

What are you trying to power with your PSU purchase? Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
Chassis:

Even if you got the grey labelled CX550 unit brand new, you should be looking at a reliably bult 650W~750W unit to power your build, consisting of an RTX3060Ti.

Stick to one thread please

Why does he need a 650w - 750w PSU for a system that consumes 300w at most?

I expect the "reliably built" statement is important, not the "650W~750W" power output which is more than enough for a modest build.

I bought an inexpensive CX550 for a 10-year old LGA1150 system and the PSU is as light as a feather (well almost). Only 3 SATA power connectors and definitely not at the top of any PSU tier list. It does the job but I wouldn't recommend a CX550 for an important build.

In another PC I have an RM650. Much better build quality. Heavier. Superior circuit design. More outlets. Modular design (which isn't essential for me).

On my server builds where I have lots of hard disks, I buy something from the RM850 series because they have 10 SATA power connectors. I don't need the 850W, but I do need lots of power outlets.

Most of my rigs bumble along at 70 to 120W so I don't need a 550W+ PSU, but it's becoming more difficult where I live to find a reasonably priced good quality PSU below 500W rating. In the past 250W AT/ATX PSUs were common.

I just put up with the cost of operating a modern PSU well below the 50% point on its efficiency curve.
