CX450M is the only quality PSU I can find for less than £50 on pcpartpicker, if you want more wattage and don't want a piece of crap you'll have to spend a bit more but 450W is fine for a GTX 1070 or lower and an LGA 1150 or Ryzen CPU.

It's actually not better quality than the CX450M, Corsair is a newer design with better construction, similar quality capacitors, and the same 5 year warranty. If you can find one for £40 then link it because I'm not seeing it.
