ZOTAC GeForce GTX 770 Extreme Edition Detailed@ 2013/07/02
The GTX 770 Extreme Edition features the same exact PCB as its predecessor, featuring a 12-phase (8+3+1) VRM, which makes use of noise-free chokes, a combination of conductive polymer and tantalum capacitors, three proadlizers (multi-phase capacitors for power conditioning), and International Rectifier PowIRstage driver-MOSFETs. A combination of CHiL CHL8318 (8-phase) and CHL 8214-03 (4-phase) chips are used to run the VRM. The main heatsink uses a copper base (not vapor-chamber) to make contact with the GPU, from which five 8 mm-thick nickel-plated copper heat pipes sprout out, transporting heat to the far-reaches of the heatsink. A pair of 92 mm PWM-controlled fans ventilate the heatsink, which are held by a sporty aluminum shroud.
