Seasonic G-650 PSU, good enough for my new Ryzen build?

[starmanwarz]

I've had the G-650 for a few years now powering an OC'ed 4770K and 780 and I'm building a new PC with:

3700X
5700 XT Nitro
16GB RAM
3 fans
2 SSD's
2 HDD's

Is it going to be enough? It was quite expensive at the time and it's supposed to be a high quality PSU according to reviews.

650 Watts is probably fine, it doesn't matter that it's older tech, right?

It's this one:

Excellent, thanks guys.

One more question, I'm also getting a new case (Fractal Design Meshify S2) and I see that in these newer cases the PSU is at the bottom of the case instead of at the top, is this going to be a problem?

The bottom of the case with the psu drawing air through a filtered vent from outside the case is where the psu should be. Having the psu at the top of the case and using it as a exhaust fan was always a bad idea as the psu will run hotter, the fan louder and the extra heat could potentially shorten the life of the psu. Also, psu's are power/efficiency rated at a certain temperature. The Seasonic G series are rated at 50 degrees C so not so bad for them but others are rated at 40 degrees or even 30 degrees or less for the poorer quality ones. Exceeding those temps will affect efficiency and power delivery and in the case of cheap psu could even make them fail.

Ahh makes sense, thanks. And I wondered what that bottom boxed area is in the Fractal Design cases
