meron ako dito 450w atx smps.

nagtataka ako 2 connectors: 20-pin & 4-pin.

although total 24 pa rin, parang di standard ang connector.

ano sa tingin niyo?

original ATX is 20 pin, then 'yung mga bago is 24 pin. kaya 'yung ibang power supply na medyo bago or during transition, merong 20 pin plus 4 pin connector (same as mine).

parang ganito:

dba mga master may nabibili nang adoptor para dito diko lang sure masyado parang yong 20 pin magiging 24pin pag nilagay ang adoptor.

may tanong nga pala ako,

bakit dami-dami ng wires ng atx, whereas paulit-ulit lang naman yung mga wires...? tulad nyang 24pins na post mo, apat na 3.3V. kung issue ang current, bakit di nalang gumamit ng isang malaking wire? dami tuloy messy wires sa loob ng casing. wala pa naman akong talent mag-ayos nyan. heheh

yung current sir, pag ginamitan ng makapal na wire mahirap i distribute sa iba't ibang peripherals, isa na rin yung noise kapag isang wire lang yung malaking bahagi ng noise galing sa isang peripheral mapupunta sa isa pang peripheral

manipis lang yung copper foil ng motherboard ... kailangan i-distribute yung current

yung mga nabibili sa pc express & villman, hiwalay ba yung 4-pin & 20-pin connectors?

balak ko kasi bumili... ang kaso baka di compatible sa mboard ko (hiwalay sila).

kahit hiwalay, pwedeng pagtabihin yan... actually, kumakabit yang hiwalay na 4pins sa connector na 20 pins...
sa tingin ko, compatible naman yan. standard naman yata ang lahat na motherboards... anong mobo mo? tignan natin yung specs...

dahil ang isang contact pin ay limitado sa 6 amperes according to spec...so kailangan ng maraming wires...ant then for every supply merong dapat na return wire, black wire yon...

mostly po may standard na ginagamit pag gagawa ang isang company ng isang ATX power supply....

they should follow those constraints in designing new one.
except pag gawa dito sa china may hokus pokus na yan malamang.

here is the lik to such standards: http://www.formfactors.org/developer/specs/ATX12V%20PSDG2.01.pdf
