Like EVGA, like Corsair, like be Quiet!, the same rules apply.
"Brands" sells units manufactured by various players in the space. Each "brand" typically has offerings from various manufacturers (SeaSonic, FSP, HEC, CWT et al) and they vary in quality. Some use an established platform with no changes, others require some tweaks.

EVGA, specifically have (among others)
500W, 430W, 500-700B etc - all HEC made any pretty poor quality. I wouldn't run anything greater than a 1050TI...
What kind of budget do you have for a PSU? And where are you located?

That's a ~250W TDP based on the CPU + GPU choice. Say 50W for the balance, a quality 450W unit could be more than capable.
Personally, I'd lean towards a quality 550W unit for a system of this nature.

The CX550 from Corsair is competitively priced, in the US at least.

650W is overkill, and "brand" alone doesn't determine quality. EVGA have some quality offerings, but they also have some pretty budget units too.
 

I said a trusted brand like EVGA, they shouldn't buy from some sketchy brand. It was just an example. And 650W leaves them some room for upgradability in the future. Not to mention, it's always good to have some extra wattage.

BT from SuperFlower and BQ's from Andyson & HEC -- Ok for budget units, a little better than ^^, but still not for heavy use IMO.
B2's and B3's from SuperFlower - Pretty decent
GS and PS from SeaSonic - Good quality
G2, G3, T2, P2 all from SuperFlower. - Good quality

Notice some of the "brands" in there play in various spaces? Built to a pricepoint as dictated by the "brand". So there's much more that goes into it than simply "a trusted brand like EVGA"

That's not to pick on EVGA specifically, they're all at it.

Some of the only "brands" who manufacture their own PSUs are SeaSonic and SuperFlower (there's a couple of others). Typically, those offerings are good quality throughout..... but I'm sure theres' some budget units that could be found.

Independent reviews of a specific unit is what you should reference, not simply a "brand" (be it EVGA or anybody else).
