psu CX450 for RTX2060 or GTX1660TI?

[Ceriumin]

Hello, I am planning on purchasing a gtx1660ti or an rtx2060 to replace my gtx1050. My system also contains these specs:

Ryzen 5 2600
16GB 3200mhz RAM
B450m-a

I have found a 1660TI mini EVGA and an RTX2060 mini EVGA (has to be mini for my case size) for the same price of £260. However my limit is my CX450 PSU. I used a wattage calculator and I average at 339 WATTS with the RTX2060 however people say its extremely innacurate. Others say the minimum requirements (in this case, the RTX2060 is 500w) is exaggerated. I have no idea whether I should risk it and buy the 2060 and experience issues or buy the 1660ti without stress. FYI i will be playing at 1080p@60 at highest settings but i may use RTX for 2 games. However for many reasons, i will not buy a new psu. Please don't go in depth about the PSU and not come up with an answer. Finally, I dont have rgb, and i will not overclock. I use 1 250GB SSD and 1TB HDD if that helps. Thanks in advance.

CX 450 is fine for your setup including RTX2060. Nothing to worry about.

450W is plenty for the R5 2600 and RTX 2060, your whole system would hit around 300W under full load (including fans/motherboard/storage), I wouldn't worry about it.

Power supply calculators are basically always wrong. 

 

Ryzen 5 2600: about 85 watts at most

Rtx 2060: 200 watts, and that's being generous

 

Only thing to mind is that the cx450 only has a single pcie 8-pin connector

Yeah I knew they were accurate but to some extent it is probably close. And I can confirm that I have a 8pin (6x2 and a extra 2x1). Does it really matter anyways that there is only 1?

It matters if you get a model that needs two

450W should be fine

Doesn't the RTX2060 only require 1 8pin PCI-e? I won't be upgrading anything further.

there are models with more connectors, though those are the more expensive models so if you're buying on the budget end it's not a problem
