MSI GTX 780 Ti Lightning Pictured, Overclocked, and Tested

Ahead of its launch, French tech publication Le Comptoir du Hardware scored an early sample, and wasted no time in taking high-res pictures of the card, its innards, and putting it through a battery of benchmarks. Their first opinion? That EVGA's GTX 780 Ti Classified K|ngp|n has met its match. Taller than most graphics cards, and thicker than two slots, MSI GTX 780 Ti Lightning is based on the same new-generation TriFrozr cooling solution as the GTX 780 Lightning. Its underlying PCB is unchanged, too. The card draws power from a pair of 8-pin PCIe power connectors, and conditions it using a gargantuan 20-phase VRM. The VRM uses two separate controllers for GPU and memory+PLL. The GPU and memory both draw power from the power connectors, while only the PLL draws power from the slot. This way, memory OC isn't held back by the PCIe slot power supply.



The PCB also features consolidated voltage measurement points, independent fan headers for each of the cooler's three fans (letting you control individual fan-speeds), and dual-BIOS. The cooling solution is features multiple aluminium fin stacks that draw heat from a large nickel-plated copper base, using seven 8 mm-thick heat pipes; which are ventilated by a trio of fans. MSI claims that the cooler is capable of handling thermal loads of up to 550W. The "Lightning" logo on the cooler's top lights up to the thermal load the cooler is handling. It's white up to 150W, gets brighter between 150W and 210W, and goes red beyond 210W.
