Will my power supply hold up any longer?

I have had my power supply for a long long time, and I can agree with other reviews that it is of great quality and is quite efficient. However, I have noticed some throttling in my system since my Ryzen upgrade and have noticed that even though I'm used to my fans sounding like a jet engine, my PSU has gotten way, way louder. Before my upgrade, while gaming with my headphones on, the sound was nonexistent, however now the sound is getting through and ruining my experience. I'm starting to wonder if I need to upgrade my little power supply.

I currently have an XFX TS 430w PSU, and it has held up but I noticed that people will similar specs to be have much larger power supplies and I'd hate to buy something new that I don't need. I never really saw this coming since my older processor had a 95 watt TDP while the Ryzen chip has a 65 watt TDP.

Current main specs:

CPU: AMD Ryzen 5 1400 @3.2GHz
RAM: 8GB Gskill Ripjaws V 2400MHz
GPU: AMD Radeon RX 470 8GB
Mobo: MSI B350 TOMAHAWK
PSU: XFX TS 430w PSU

My previous CPU was an AMD X4 880K @4.0GHz with a Gigabyte F2A68HM-HD2 and it provided a severe bottleneck with my GPU

The PSU doesn't have any way of affecting CPU or GPU clocks. It either provides enough clean power or it doesn't and the PC shuts down or reboots.

If you want something quiet, the power rating does not matter that much as long as you have enough from a good quality PSU since a 80+ Bronze PSU will produce about as much waste heat for a given output power regardless of whether it is rated 430W or 850W. If you want to really cut down on noise, you need to reduce the amount of waste heat the PSU produce and that means looking at 80+ Gold or better.

Of course, a slight bump in output power margin wouldn't hurt either. (And may be necessary since there aren't many good quality 80+ Gold PSUs below 500W to choose from anyway.)
