More Features

EVGA nForce 790i Ultra SLI comes with other smaller features, like on-board reset and power switches, which are quite convenient for overclockers.

This motherboard also has a POST (Power On Self Test) diagnostics display. This feature allows you to know through a series of two-digit codes what is wrong if your computer doesn’t turn on.

This motherboard uses solid aluminum capacitors on the voltage regulator circuit, as you can see in Figure 6. This is great because it prevents the infamous capacitor leakage problem. The other electrolytic capacitors used on this motherboard, however, are regular ones, manufactured by Samxon, which is a Chinese company (Japanese capacitors are better). This motherboard also uses ferrite chokes on the voltage regulator circuit, which is great, as they provide a lower power loss. In fact we had complained that on EVGA nForce 780i motherboard the manufacturer used regular iron coils instead of ferrite ones and is always good to see whenever a manufacturer improves the quality of their products.
