Capstone G is so-so. Voltage regulation and ripple suppression are okay by today's standards when compared to high-end units that get 0.3% regulation and under 20mv on all rails. but all is within spec. It does have Unicon capacitors which OklahomaWolf says is completely unknown to him, so that's another problem, and it's an electrolytic. Enesol polymers are no concern, but the Unicon is.
I think you're going off the review for the unit he linked to, which is not the same as the model he linked to on PCPartpicker, however, even the techpowerup review for the 1000w G Capstone says:
Voltage regulation could be tighter
I expected a little higher overall efficiency, and the 5VSB rail is inefficient as well
No MOV in the transient filtering stage
Noisy operation overall
Less than 16 ms hold-up time
All of which indicates a less than great unit, but there's clearly worse choices out there. For my money, I'd go with this, IF you actually need a 1000w unit, which is unlikely unless you're running a high end crossfire configuration:
