8-pin PCIe to ATX 12VHPWR Adapter Included with RTX 40-series Graphics Cards Has a Limited Service-Life of 30 Connect-Disconnect Cycles

PSUs with native 12+4 pin ATX 12VHPWR connectors are few and far between, which means some of the first adopters of the GeForce RTX 4090 "Ada" graphics cards will rely on the adapter cable that converts 8-pin PCIe power connectors into one 12VHPWR connector that plugs into the graphics card. Cards that stick to the baseline specs include adapters that convert three 8-pin PCIe connectors (for 450 W output that matches the RTX 4090 reference specs); whereas some premium overclocked RTX 4090 cards, such as the ZOTAC RTX 4090 AMP Extreme, include adapters that convert as many as four 8-pin PCIe to a 12VHPWR, maxing out its 600 W power delivery capability. The product page of the ZOTAC AMP Extreme has an interesting sentence describing this in-box adapter: "Limited service life with up to 30 connect / disconnects."

Apparently the adapter is only good for up to 30 connect/disconnect cycles safely, before you'll need another one. For most gamers who'll install the card and forget about it for years, this shouldn't be an issue. However, for overclockers and enthusiasts using the card on an open-air bench and who rely on a lot of moving cards around, this could be an irritant. Tech journalists (reviewers) swap graphics cards out a lot, too, but then they're likely to have several such adapters lying around from multiple samples, or a PSU with a native 12+4 pin connector.
