I currently have this budget build.

I am planning on making the following upgrades (i.e., RAM, CPU, GPU, cooler, storage) if I can get them for cheap on Black Friday/Cyber Monday.

According to the voltage estimator, I can still run things with my current PSU. However, if I could snag a way better PSU for relatively cheap, say 850W, perhaps I should. That way I will be set for a new PC in 4-5 years (PSU wise).

Is there any issues with going with such a high PSU relative to computer voltage?

If there are other suggestions, I am from Canada.
Thanks.
