[OC Guide] Buildzoid and the GTX 570 Epower Project

Buildzoid has put together an interesting video which covers everything related to adding an power board to a video card. For most hardcore, extreme overclockers installing a power board might not be the most difficult thing in world, but for many less experienced Overclockers it can be a fairly daunting task. Many of Buildzoid’s YouTube followers (fans?) were in the dark about what power boards are, so the purpose of this video is to generally demystify what one is, what it does, and how it works – a great tutorial for newer Overclockers.

Buildzoid starts by giving an intro of what a power board actually is by introducing his modded GTX 570 card to which he added an EVGA Epower board. The card is pretty long in the tooth at this stage, but regardless it’s a card that at some point really benefited by having a power board added. The card in question is a GeForce GTX Sonic Edition from Palit. As GTX 570 cards go this one has what could be a called a fairy under-powered VRM (or a pretty crap one to use Buildziod’s colorful vernacular). It has a four phase VRM which frankly no Overclocker would trust too much beyond stock settings and stock voltages, which is why it was a ripe candidate for such a mod.

To remedy the card’s less than stellar VRM, the installation of an EVGA Epower card was the perfect solution to unleashing the true potential of the Nvidia Fermi GPU. The Epower card allows you to add an EVGA Classified specification VRM, similar to what EVGA used on their Classified GTX 680 and 780 cards – in other word, a damn fine VRM. The card features 14 phases, plus control circuitry. The Mosfets and controllers used are from International Rectifier and are pretty good quality.

As well as the Epower board, Buidlzoid also covers the modifications he made on the rear of the card, including various sensors and more. You can find the video here on the Actually Hardcore Overclocking YouTube channel.
