Using a power supply tester, a technician measures the +12 V rail at 11.1 V under load. ATX supplies should stay within ±5% of nominal. What should they conclude?

Answers
AThe reading is normal, because any value above 10 V is acceptableLa mesure est normale, car toute valeur supérieure à 10 V est acceptable
BIt is out of tolerance, so the power supply should be replacedElle est hors tolérance : l'alimentation doit être remplacée
CThe tester needs new batteries, so the reading can be ignoredLe testeur a besoin de piles neuves, donc la mesure peut être ignorée
