Micro ATX vs Mini ITX
Mini-ITX thiab micro-ATX yog cov qauv hauv computer desktop. Lawv txhais cov xwm txheej tshwj xeeb ntawm qhov loj me, lub zog xav tau thiab cov khoom siv, peripheral connector / add-ons thiab connector hom ntawm lub computer system. Nws feem ntau cuam tshuam txog kev teeb tsa ntawm lub motherboard, chav tsev fais fab thiab lub chassis ntawm lub computer system.
Micro ATX
Micro ATX, tseem hu ua uATX, mATX, lossis µATX, yog tus qauv qhia hauv xyoo 1997 raws li ATX specification. ATX yog tus qauv tshwj xeeb ntawm cov motherboard tsim los ntawm Intel lub tuam txhab hauv xyoo 1995 raws li kev nce qib los ntawm AT tus qauv. ATX sawv cev rau Advanced Technology eXtended. Nws yog thawj qhov kev hloov pauv loj ua rau kho vajtse teeb tsa ntawm lub khoos phis tawj hom duab.
Cov lus qhia ATX txhais tau hais tias qhov ntsuas qhov ntev, cov ntsiab lus txuas, Cov Khoom Siv / Cov Khoom Siv Hluav Taws Xob thiab cov khoom sib txuas ntawm cov motherboard, lub zog, thiab lub chassis. Nrog rau qhov tshiab specification, interchangeability tau qhia nyob rau hauv ntau lub Cheebtsam ntawm hardware, nyob rau hauv lub desktop computers. General microATX board muaj qhov ntev ntawm 244 x 244 mm.
ATX tus qauv qhia txog lub peev xwm los siv ib ntu ntawm qhov system rau add-ons thiab txuas ntxiv rau lub motherboard, thiab nws feem ntau hu ua Input / output vaj huam sib luag, uas yog lub vaj huam sib luag tom qab ntawm lub chassis thiab siv los txuas cov khoom siv. Kev teeb tsa ntawm I / O vaj huam sib luag yog tsim los ntawm cov chaw tsim khoom, tab sis tus qauv tso cai yooj yim rau kev nkag mus uas tsis muaj nyob rau hauv AT configuration ua ntej. Cov yam ntxwv no muaj nyob hauv cov tshuab micro ATX tshiab, ib yam nkaus.
ATX kuj tau qhia PS2 mini-DIN connectors rau kev sib txuas cov keyboards thiab nas mus rau motherboards. 25 tus pin parallel chaw nres nkoj thiab RS- 232 serial chaw nres nkoj yog qhov tseem ceeb tshaj plaws ntawm cov khoom txuas txuas rau hauv ATX motherboards thaum ntxov. Tom qab ntawd, Universal Serial Bus (USB) connectors tau hloov cov khoom txuas saum toj no. Tsis tas li Ethernet, FireWire, eSATA, audio ports (ob leeg analog thiab S / PDIF), video (analog D-sub, DVI, HDMI) tau teeb tsa hauv cov tshiab versions ntawm ATX motherboards. Lub micro ATX tuaj yeem suav hais tias yog ib qho txiaj ntsig ntawm ATX tus qauv. Cov ntsiab lus mounting yog tib yam; li no tso cai rau micro ATX motherboards kom sib haum nrog lub chassis ntawm tus qauv ATX system board. Lub ntsiab I / O vaj huam sib luag thiab cov khoom siv hluav taws xob yog tib yam, tso cai rau cov khoom siv thiab cov khoom siv sib hloov tau. Txawm li cas los xij, tus naj npawb ntawm cov khoom sib txuas tam sim no hauv microATX board yog qis dua tus qauv ATX board.
Lub hwj chim siv hauv microATX tshuab yog tib yam li ib qho siv hauv ATX. Lub hwj huam mov muaj peb lub ntsiab zis voltages ntawm +3.3 V, +5 V, thiab +12 V. Ntxiv Low-power −12 V thiab 5 V standby voltage kuj muaj. Lub hwj chim txuas nrog lub motherboard siv 20 connector, uas yog tsim los txo cov kev sib txuas tsis raug uas yuav ua rau muaj kev puas tsuaj tsis zoo. Nws kuj tseem muab +3.3V khoom ncaj qha thiab tshem tawm qhov yuav tsum tau ua kom 3.3V tau txais los ntawm 5V mov.
Mini-ITX
Mini-ITX yog ib daim qauv ntawm cov motherboard uas tsis muaj zog uas tsim los ntawm VIA thev naus laus zis hauv xyoo 2001 thiab feem ntau siv hauv cov qauv me me hauv computer architectures.
Lub mini-ITX (mITX) raws li khoos phis tawj muaj kev ua tau zoo piv rau cov qauv zoo sib xws nrog kev siv hluav taws xob qis dua. Mini-ITX motherboards muaj tib lub qhov mounting li ATX, ua rau cov laug cam muaj peev xwm muab ntsia tau rau hauv chassis tsim los rau cov qauv lossis MicroATX motherboards. Lawv muaj tsawg dua qhov nthuav dav dua li microATX motherboard. Txawm li cas los xij, ua suab nrov tsawg dua piv rau lwm lub tshuab ua rau nws zoo tagnrho rau cov tshuab computer me thiab nyob ntsiag to. Yog li ntawd, lawv feem ntau siv ua yeeb yam hauv tsev PC's.
Thaum ntxov, lub mITX siv EPIA 5000 thiab EPIA 800 processors, uas kuj yog tsim los ntawm VIA technologies. Txawm li cas los xij, tam sim no lwm cov tuam txhab tau lees txais mITX thiab ob qho tib si Intel thiab AMD processors txhawb nqa mITX architecture.
Mini ITX vs Micro ATX
• Micro ATX yog daim ntawv qhia tshwj xeeb tsim los ntawm Intel Corporation raws li ATX specification. Mini-ITX yog tsim los ntawm VIA technologies.
• Mini ITX me dua micro ATX.
• mITX tsuas muaj ib qho PCIE nthuav dav thaum micro ITX muaj ntau dua ib qho kev nthuav dav, tab sis tsawg dua tus qauv ATX system.
• Mini-ITX ua suab nrov tsawg dua piv rau microATX raws computers.
