    nem érdekel ez most :) ez számomra zéró infó, és asszem neki is. Erre ugyan kár sávszélességet pazarolnod :)

    Én csak annyit hámoztam ki eddig, hogy az UVP opcionális dolog, mert nem is része az ATX specifikációnak, illetve egy másik fórumon találtam róla ezeket:

    Under Voltage Protection (UVP)

    "UVP is on the DC side of things.
    Let's say your +12V drops to +10V. This will force your motherboard, graphics cards, etc. components to work harder to maintain THEIR operating voltages. A good power supply has full range voltage input capability (typically 90V to 260V) and transient filters. Odds are that a brown out the drops your line voltage from 120V to 90V isn't even going to faze your power supply. If there's a near power outage, odds are the PSU is just going to shut off and you'll lose whatever you're doing or working on. That's where a UPS comes in handy. Even if power goes out, your UPS will keep your PC running. If you're worried about frequent brown outs, you can always get a line condition to keep your line voltage at a steady 120V, but if you get a decent line interactive or online UPS, it's going to have voltage regulation built in, so I would just go that route.

    UVP is important for fault protection and short circuit protection.

    AC UVP is often referred to as "brownout protection". As AC voltage drops, the current across the APFC components increases, so low AC means high stress on APFC. Most APFC controller have brownout protection features."
