Lub hwj chim mov hauv PC muab ntau qhov hluav taws xob rau cov khoom siv sab hauv hauv lub computer los ntawm cov khoom siv hluav taws xob. Cov voltages no tsis tas yuav muaj tseeb, tab sis lawv tsuas tuaj yeem sib txawv nce lossis nqis los ntawm qee qhov nyiaj, hu ua kam rau ua.
Yog tias lub tshuab hluav taws xob muab cov khoom siv ntawm lub khoos phis tawj nrog qhov tshwj xeeb qhov hluav taws xob sab nraud qhov kev zam no, cov khoom siv hluav taws xob yuav tsis ua haujlwm zoo-lossis tag nrho.
Hauv qab no yog cov lus teev cov kev zam rau txhua lub zog hluav taws xob hluav taws xob hluav taws xob raws li Version 2.2 ntawm ATX Specification (PDF).
Power Supply Voltage Tolerances (ATX v2.2)
| PSU Tolerance Table | |||
|---|---|---|---|
| Voltage Rail | Kev siab ntev | Tsawg Voltage | siab tshaj voltage |
| +3.3VDC | ±5% | +3.135 VDC | +3.465 VDC |
| +5VDC | ±5% | +4.750 VDC | +5.250 VDC |
| +5VSB | ±5% | +4.750 VDC | +5.250 VDC |
| -5VDC (yog siv) | ± 10% | -4.500 VDC | -5.500 VDC |
| +12VDC | ±5% | +11.400 VDC | +12.600 VDC |
| -12VDC | ± 10% | -10.800 VDC | - 13.200 VDC |
Txhawm rau pab thaum kuaj cov khoom siv hluav taws xob, peb kuj tau suav qhov tsawg kawg nkaus thiab qhov siab tshaj plaws uas siv cov kev kam rau ua tau teev tseg. Koj tuaj yeem siv peb ATX Power Supply Pinout Tables rau cov ntsiab lus ntawm lub hwj chim txuas pins muab qhov voltage.
Power Good Ncua sijhawm yog lub sijhawm nws yuav siv lub zog hluav taws xob los pib ua tiav thiab pib xa cov hluav taws xob zoo rau cov khoom siv sib txuas. Raws li Desktop Platform Form Factors Power Supply Guide [PDF], Fais Fab Kev ncua sij hawm (hu ua PWR_OK ncua sij hawm hauv daim ntawv) yuav tsum yog 100–500 ms.
