Hi all, recently my computer had coil whine issues. I singled out the components that was making the noise was the PSU.

System Specs:
I7 4790
H97 PC MATE
Zotac GTX 1070 8GB mini
Hyper Evo 212 Led
Hexa Core 80+ 550W PSU

The screeching sound comes on and off, it isn't affected by games or anything it just random. Is this problem serious? Will it adversely affect the other components?

I actually want to upgrade/change my pc but I plan to do it maybe mid next year or maybe even this christmas if pc parts are on sale. I do know that the PSU isn't exactly good and definitely want to get a much higher quality one, so can I afford to wait? Would really appreciate some advice!
