My Enermax Revolution D.F. 750W recently failed after running a Ryzen 7 5800X3D, RTX 3070 Ti, and MSI B550M Mortar system reliably. The computer was completely dead with that PSU but booted immediately after I installed an older 850W unit, so I'm confident the Enermax was the problem.
Since I need a replacement, I'd rather buy a high-end, future-proof unit than another 750–850W model. I may eventually run two powerful GPUs drawing roughly 350–400W each, so I'm looking in the 1500–1600W range.
The system is housed in a Thermaltake CTE T500 TG ARGB Snow, which has an approximately 180mm PSU length limit. My priorities are excellent electrical performance and protections, strong transient handling, ATX 3.1 support, two native 12V-2x6 connectors if possible, full modularity, and a 10-year warranty. I'm more interested in platform quality and independent testing than the 80 Plus label alone.
The NZXT C1500 Platinum currently looks promising because it is 1500W, ATX 3.1, 180mm long, and includes two native 600W GPU connectors. I'm also considering the Thermaltake Toughpower TF3 1650W Titanium and the older GF3 1650W, although the TF3 seems to include only one native 12+4 GPU cable.
Are there other top-tier 1500–1650W PSUs that are 180mm or shorter, and which model would you choose for this setup?

The ASRock Taichi TC-1650T looks like one of the best matches. It is 180mm long, fully modular, ATX 3.1, Titanium-rated, has two native 12V-2x6 cables, and comes with a 10-year warranty. Independent testing also shows strong overall performance, so it fits your requirements better than many larger 1600W models.
The NZXT C1500 Platinum seems like a very practical choice here. Its 180mm length, ATX 3.1 design, dual native 12V-2x6 connectors, and strong independent test results line up closely with your goals. I’d compare its protections, noise profile, and warranty terms directly against the ASRock before deciding, rather than choosing solely by the Titanium versus Platinum efficiency label.
The Seasonic Prime TX-1600 is an excellent platform, but it is too long for a case limited to 180mm. It would be worth considering only if you change cases later. Also keep in mind that a 1600W PSU can place substantial demand on a household circuit when heavily loaded; in North America, checking the circuit rating is sensible before planning sustained loads above roughly 1400W.
