HP Omen 500W PSU

I'm thinking about purchasing an HP OMEN prebuilt gaming desktop. I'm concerned because it only has a 500W PSU. It also has a 8700k CPU and a 1080TI GPU. Is the 500W PSU powerful enough to run games at 4k resolution without putting too much stress on the system and causing problems later down the road?

While 500W PSU can power the HP Omen, it's too close for comfort. GTX 1080 Ti is 250W GPU, add the rest of the system to it at 200W and you're looking 450W. OC your CPU/GPU and you're looking to blow your PSU.

For a system like that, minimum PSU wattage should be at least 600W (according to Nvidia) while 650W is a safe zone. So, if you go with that prebuilt, replace the PSU with higher wattage one. Anything from Seasonic is solid choice, e.g Seasonic PRIME 650 80+ Titanium (which is the best 650W PSU money can buy at current date and which also powers my Skylake build, full specs with pics in my sig).
