The video card will be fine for that price, although you won't get amazing performance out of it. (a mix of medium and high settings should get you 60 FPS at 1080p in almost all modern games). The Kingston SSD is also well priced (hopefully it's the newer UV400 version, the V300 has a bit of a nasty reputation when it comes to performance)
If you plan on upgrading your GPU then when looking for a power supply don't skimp on it. Make sure it's 80+ rated, with active PFC and all of the other protections inside and has at least 1 PCI-E 8/6 pin cable (I don't think the GPU you currently selected needs one though according to EVGA's website, unless the link you gave is not the exact model with those clock speeds). As long as the GPU has at least 1 external power cable for GPUs, even if future GPUs need more than 1 you can just use some cheap 2x4pin (molex) to PCI-E 6Pin adapter cables.
Depending on what you plan on upgrading to, we are looking at different power requirements: for up to RX 580 or GTX 1060 6GB an 500W PSU should be enough (450W will be cutting it close for an RX 580 - it depends on the other components). Beyond that you might be looking at 600 to 800W (for an GTX 1080 TI you want a minimum of 600W with 750W being optimal)
If you plan on using SLI/Crossfire (which I don't recommend) make sure the PSU has enough amps on its +12V rails to power everything (the GTX 1050 and 1060 don't support SLI).
Yeah, it's the UV400. To be honest I'm absolutely fine with that GPU, as I said if it's not doing what I want I'll switch it out after a while. Thanks for the advice on the PSU, I'll be looking for one soon.
