If your power consumption is actually 250 then go for a 500w PSU. You'll get better efficiency.
Anandtech (rip) used to be my go-to for PSU efficiency curves.
Also never cheap out on the PSU. If your shit PSU dies, it might fry every component in your PC, if your good PSU dies, you can just replace it.
I once had a PSU fail catastrophically- arcing, visible from around a corner and down a hall, and quite loud. I didn't want to go near it, circuit breakers were closer anyway, but I didn't know which one so I just hit them all. Once replaced, I fired up the machine and... I think the cmos was cleared, but other than that, no ill effects.
Better efficiency is only part of it, you'll also get better longevity on the power supply.
I have a few 1k watt PSUs left over from my bitcoin mining days and all but one of them are still good.
