I am going to be building a new PC as mine is really outdated. However i can remember changing the PSU and not long after the PC just got put in storage and forgot about. It is a Corsair CX500. I know its not modular but the new PC is on a super tight budget. Will be powering a ryzen 5 1600 or 3200 and a GTX1660 or RTX2060. Storage will just be SSD and nothin special with cooling.
Thanks in advance for your input.

Ryzen 5 CPU and a mid range GPU isn't exactly a "super tight budget".

Since we don't know exactly what you need, and with what budget, it's tough to say. I'd definitely be aiming to replace that CX500 though. It's an old, low quality unit.

Your PSU should be able to handle that just fine. So long as you don't try any overclocking especially on the RTX card if you decide for the upgrade. The power draw in overclocking RTX and Ryzen 2 CPUs is pretty impressive.. I'd recommend a new PSU if the one you have is 5+ years old though, and in terms for upgrading you want to always have about 200 watts in the case for overclocking and keeping yourself somewhere within your efficiency curve.

Hmm, not entirely. Wattage isn't the issue, it's the quality of the unit. 500W is perfectly sufficient for an overclocked R5 3600+RTX 2060, so long as it is good quality. It's not necessarily ideal, but it's definitely enough.

Do you mean they draw a lot of power when overclocked? If so, not really. You're not going to be messing with voltage on NVidia GPU's, so "overclocking" them isn't going to hugely increase power consumption. Also, they pretty much do the job themselves now with GPU boost anyway really.
As for Zen2, it doesn't have much overclocking headroom anyway, but even if you do manage to get a decent manual overclock, it's also not going to significantly increase power consumption. Unless, of course, you're using a 3950x on LN2 or something ridiculous.

An R5 3600 @ 4.3GHz all core will still pull less than 100W.
The RTX 2060 is going to be pulling roughly 250W, give or take depending on specific model and whether or not it's overclocked. 225W on the lower end under load, and it's unlikely that even the highest end, manually overclocked RTX 2060's will pull more than 325-350W.

I'd agree that an upgrade is a good idea though.
