Environmentally
friendly computer hardware is a growing trend, and while performance videocards
are usually the worst power-hogs the situation is steadily improving.
The ASUS EAH4890 uses two 6-pin PCI Express power
connectors in addition to the power it draws from the PCI Express x16 slot
(total card power ~190W). This is a little less complicated than high-end
videocards that demand the less common 8-pin PCI Express connector. Let's take a look at how much power the ASUS EAH4890
draws in a typical computer system.
Total System Power Draw
Comparisons
Here's how the ASUS EAH 4890 HTDI/1GD5/A videocard
stacks up in real life against a couple different cards. PCSTATS measures total
system power draw and compares that in 3D loaded (max value recorded in
3DMark06) and idle states (at Windows desktop).
The power supply used in each test is an A-PFC compliant
PC Power and Cooling 750W model.

Overall power draw numbers show that while the ASUS
EAH4890 HTDI/1GD5/A videocard does require two PCI Express power connectors,
this videocard is hardly a power hog. Under load it draws significantly less
power than older dual-GPU AMD Radeon videocards or NVIDIA videocards in SLI
mode, the two configurations that come closest to matching its performance.
Next up PCSTATS overclocks the ASUS EAH4890 HTDI/1GD5/A,
boosts the GPU voltage, then overclock it some more!
