Do I have to buy new PSU?

[konditv]

Hi!
My current specification is:

i5 10400f
Cpu cooler SPC Fera 5
Msi h510m-a pro
Palit gtx 1050 2gb
Kingston fury 2x8gb 3200Mhz (I know its only working 2666Mhz on my motherboard)
ssd samsung evo 860 250gb
hdd toshiba p300 500gb
Monitor Acer KA242Ybi 24inch FHD
2nd Monitor some sort of old office Dell 19inch

PSU: be quiet! system power 8 400W 80+

I want to buy a new GPU and im thinking about one of RX 6600/6600XT/6700. Budget is tight so most likely its gonna be RX 6600. The question is, will my psu be enough or do I need to buy a new one?

Thanks for any advice!

Ideally, yeah, but I think it's worth a try with the bequiet, so I'd only upgrade if you have problems.

Thanks.
But if I was to buy a new PSU in overclockers shop, which one would you recommend? max price 70£. I can also get Corsair TX550M 550W Gold for 70£ on amazon if its better than those in oc shop.
