It comes down to two numbers. ASUS recommends a 550W PSU for the RX 9060 XT and a 750W unit for the RTX 4070 SUPER. The RTX 4070 SUPER has 12GB of VRAM, while the RX 9060 XT has 8GB. So if you want a lower PSU recommendation, look at the RX 9060 XT; if you care more about memory, look at the RTX 4070 SUPER. Both cards are listed as 2.5-slot. They each use one power connector, but it's a different type on each card, so the connector doesn't make either one better.
Condition:
- The 750W figure is ASUS's recommended PSU for the PRIME GeForce RTX 4070 SUPER 12GB GDDR6X OC Edition, not for every RTX 4070 SUPER card.
- The 550W figure is ASUS's recommended PSU for the Dual Radeon RX9060XT 8G GDDR6, not for every RX 9060 XT card.
- The RTX 4070 SUPER's 12GB is GDDR6X. The RX 9060 XT's 8GB is GDDR6.
- The RTX 4070 SUPER takes one 16-pin connector. The RX 9060 XT takes one 8-pin connector.
