I'm building a system with a Ryzen 7 7700X, RTX 5070 Ti, 32GB of DDR5 memory, two SSDs totaling 2TB, and a B650 motherboard. My current power supply is an Antec Atom G 750W 80+ Gold semi-modular unit. It doesn't have a native 16-pin connector, so I would need to use the adapter included with the graphics card. Should I replace it with something like the NZXT C1000 Gold Core, or is the current 750W unit sufficient? I'm based in Southeast Asia and don't expect to upgrade my graphics card until around 2030.

The 750W capacity should be enough for this configuration, so you don’t need to jump all the way to 1000W. The main reason to replace the current unit would be getting a newer, higher-quality power supply with a native 16-pin GPU connector instead of relying on the adapter. Availability and pricing in Southeast Asia may affect which model makes the most sense.
The Antec Atom G is generally considered a lower-tier unit than the better modern options. For a 5070 Ti, I’d prefer a reputable high-tier 750W or 850W model with the appropriate native connector. An NZXT C750 should be sufficient if it is the current ATX 3.x version and has the required 16-pin cable, especially since you aren’t planning a future GPU upgrade. Just verify the exact model and connector before buying.
That clears things up—if a 750W NZXT is enough, I’d rather spend about $100 on that than pay extra for a 1000W unit.
I’m in Southeast Asia. Is there anything better than the NZXT C1000 Gold Core that I should consider?
