EVGA GTX 580 Classified Internal Details
For graphic cards with custom PCB's like the EVGA GTX 580 Classified a look under the hood can bring new found understanding to the purpose of a card.
Once we remove the plastic shroud surrounding the Classified we start see some of the magic that EVGA has included in its latest iteration of the GTX 580. First we have the large 8cm blower style fan that helps give some much needed extra cooling to the entire card. Following that we have a slightly redesigned heatsink that dissipates part of the heat generated into a user's system but for the most part will exhaust all heat out of the rear of the Classified.
To see the bare PCB of the GTX 580 Classified we must first remove a the heatsink that covers the entire PCB board helping give some much needed cooling to the VRM's and other components. Under that we have what looks like a normal GTX 580 except every component has been overdesigned to take the extra abuse that overclocking can generate.
Rather than Samsung GDDR5 memory that we are typically finding on cards we review on Benchmark Review EVGA has used twelve Hynix H5GQ2H24MFR-T2C 2Gb GDDR5 memory modules to create the 3GB framebuffer the Classified has. Each of these modules is rated for up to 5Gbps at 1.5v.
EVGA has included three NEC/Token 0E907 film capacitors on the Classified. Each capacitor is rated for 2.5v and 900uF and is designed to help provide a cleaner power input to both the GPU and the VRAM.
EVGA claims that the Classified is able to handle 1000w of power. In order to achieve this EVGA has used quite a large number of VRM's and power management circuits to help make sure all of this power is delivered in a safe and clean method so that users can get the best possible overclocks out of the Classified.
