more power through the same wire gauge, 800 VDC versus 415 VAC — NVIDIA's October 2025 figure, stated without a published basis

|---|---|
| Scope | NVIDIA's own statement, comparing a three-wire DC feed (POS/RTN/PE) with four-conductor 415 VAC; the article gives no gauge, ampacity, power factor or calculation. Its May 2025 article gave ~85% for the same shift. |
| Caveat | Not a sizing figure. At equal current per current-carrying conductor, a two-wire 800 VDC circuit carries about 11% more power than a three-phase 415 VAC circuit at unity power factor (800·I vs √3·415·I), and about 1.7× the power per current-carrying conductor (400·I vs ~240·I). Chapter 4.7 works the comparison. |
