i have an old PC that i plan on upgrading next year i hope, but meanwhile my PSU is acting up, my current specs are fx 4130, r7 and 8 gb ram dd3, plus some crappy mobo from asrock 93n78dfx (cause i can be really cheap sometimes), 1 hdd and 1 dvd writer

Is there any solid psu i could buy around 75 euros, preferrably bellow that can support my current build and in the future maybe something like a ryzen and also an ssd?

My old psu was something cheap at 650w but upon further reading the wattage don't seem to matter as much as i thought
 
Solution
If you can find the CX550 or CX550M for ~7EUR more (and available locally) then sure, go for it. No harm in having a little extra available.
