I have a core i5 3470 and a Foxconn 2ABF Motherboard. What Would Be A Good Graphics Card For This?

I am looking to upgrade my EVGA GTX 750 TI SC to EVGA GTX 960 SSC but I only have an EVGA 400w psu. My specs: AMD Ryzen 5 1400 @3.75ghz (I can go back to base clock speeds if I have to) 2 x 8 gb 3000mhz ram Asrock B450m Pro 4 Deepcool cpu cooler 4 case fans ssd and 7200rpm hdd Will I be able...

My power supply is a Cooler Master Elite Power 400w (rs-400-psar-i3).I know that this psu is not a good one but i don't really want to change my psu at this time.And I also have an SSD in my system.

i'm planning on upgrading my GPU from GTX 1050 Ti to GTX 1660 Ti. I'm concerned whether my PSU is enough for the new GPU Mobo: Asus H81M-D CPU: i7-4790 RAM: 2x 8GB 1600 DDR3 HDD: 1x 1T, 1x 160GB PSU: Silverstone 400W PSU Has CPU water cooler but forgot what the brand or model is NO case fan

So, my PC is using Ryzen 3 2200G, i've used it for doing programming works and some gaming, i didn't use any VGA since i built it. When i play some game such dota2 / paladin / etc, i usually OC it little (arround 3,8Ghz for cpu and 1500Mhz Gfx), i won't push it harder cuz i feel i don't need it...
