Chapter 1: Ang suliranin.





Last June 2004 ko lang nakuha itong psu padala mula sa Amerika.  Stable naman siya(Overclocked settings) for about 3 weeks of normal use when weird things began to occur.  Merong mga pagkakataon na pag press ko yung power button, tatakbo yung pc pero bigla na lang siya mamamatay.  Mga less than one second naka on then biglang off.  Ni reseat ko lahat ng peripherals, nagkabit ng wire for ground, ni reset ang bios, then test ulit kung gagana na.  Still, pag press ko ng on button, tatakbo siya then biglang mag o off.



Medyo nagduda na ako at sinalpak ko ang generic 300w psu na kasama dati sa tornado case ko.  Pinindot ang power button at gumana naman siya.  Normal naman lahat at walang instability issues. Binalik ko siya sa default clocks then switch ulit dun sa ttake psu.  Binuksan ulit ang pc ngunit bumalik na naman ang problema…



Confident pa rin ako dahil baka may issues lang sa peripherals ko kaya nag isolate ako isa isa. Still, ganon pa rin yung problema…  Isip, isip, isip…  Ginamit ko na ang brute force method(explained later) dahil desperado akong mapagana yung psu.





Brute Force Method (explained)



Nag experiment ako dun sa mga molex ng psu. Pinagpalit palit at isa isa inaysolate hanggang sa makarating ako dun sa 20wire power rail na nag ffeed ng power sa board.  Habang naka on yung voltage regulator, tinanggal ko yung 20wire power rail sa mobo at sinalpak ito muli(halfway). Nagulat ako at tumakbo yung computer(without pressing the power button). Umikot ang fans, umilaw ang leds, etc. Pero this time, naka red lang yung hdd led at parang walang activity yung pc kundi on lang siya.  Tinulak ko yung 20wire power rail para kumabit ng todo at namatay yung pc. Pinindot ko yung power button at voila, no probs at naka boot ako hanggang sa desktop.







Chapter 2: WTF?





Ginamit ko siya ng ilang oras para ma test for stability. Nag overclock ulit then check for stability. Tumakbo siya ng matino for about 1 week at sa hindi inaasahang pagkakataon, bumalik ang dating problema. Pag pinipindot ko yung power button, natakbo siya for about one second then mamamatay na lang bigla. Naalala ko yung Brute Force Method at ginawa ko ulit ito. Tinanggal ang power rail na nagffeed sa mobo at sinalpak ito muli(halfway) habang naka on ang voltage regulator. Voila! Tumakbo siya ngunit walang activity. Binaon ko yung power rail at namatay yung pc. Pinindot ko yung power button at tumakbo na siya ng normal at nakabalik sa desktop.





Epox 8K9Ai lang ang mobo ko noon. Nagduda ako dun sa motherboard ko kasi baka yung power rail port ang may problema. Since may plano naman talaga ako magpalit para maging nforce2 na ako, bumili ako ng epox 8rda3i.



Kinalas ko ang lumang mobo at kinabit ang bagong 8rda3i.  Akala ko’y dito na matatapos ang nakakaasar na problema ng pc. At sa hindi inaasahang pagkakataon, pag pindot ko ng power button, nandun pa rin ang problema--Mag oon siya ng mga 1sec then mamamatay na lang bigla. Ginawa ko ulit ang Brute Force Method at gumana naman siya ng normal muli.





Chapter 3: Pagkabigo





Hindi naman  ako nawalan ng pag-asa at masaya pa rin ako hanggang ngayon sa psu na mejo may toyo. Hanggat napapatakbo ko siya ay masaya pa rin ako kahit may mga pagkakataon na bumabalik ang problema dahil May Brute Force Method naman ako hehehe.



Walang specific date at totally random pag nangyayari yung sumpong ng pc na ito hanggang ngayon. Dumating ako sa punto na hindi na gumagana ang Brute Force Method. Hindi ko na siya mapatakbo ng normal at lagi na lang sya namamatay pag bubuksan ko. Stock psu na lang gamit ko ngayon. Mejo mahina at hindi na stable ang pc di tulad nung sa dating psu.



Ilang buwan ko rin ito pinag eksperimentuhan at tiniis para hindi I post sa ppc. Ngayong dumating na ako sa sukdulan, panahon na siguro para maikwento ang aking suliranin…





Chapter 4: TULONG!



Mga peepol at ekspert, na experience nyo na ba ito ?

May remedy pa ba ?

Sayang naman psu ko :(



Chapter 5: Pasensya na



Pasensya sa post kong ito. Sobrang desperado talaga at bwisit na bwisit na aku sa psu na ito. Salamat :)

master tony,



maari po bang mag post kayo dito ng schematics and somewhat detailed instructions fot modifying/reinforcing the power supplies that come with the cases today like tornado, epraizer etc.



thanks po and good luck

I have a generic 350Watts psu, i use it to power my Mobo pent4 2.8, 512ddr, dvd cdrw combo, cdrw, 80g hd with hd cooler, gforce5600U, and 9 fans! 11 including nb chipset fan and coolermaster cpu fan. Ok naman psu never encounterd problems. naka chempo lang ako siguro ng ok na generic, knock on wood! But im going to buy an enermax 475W! im upgrading my rig to a prescott or canterwood, a 915 or maybe 925 chips, i cant use my generic 350w coz it has only a 20pin power connector. aka atx v1.3

saan po kukuha ng power yung 2nd psu? can you piggyback it to the psu that powers the mobo?

Nasa Russia yata si Tony ngayon.

Just saw this discussion on ATX PSUs with 20 or 24 pin cables when using a MSI K8 Neo4:

Quote
The 24 pin connector is called EPS12V. This is a non-ATX but ATX-derived spec created by the Server System Infrastructure (SSI) group that has been until now reserved for serve r (multiprocessor) boards. It includes a 24pin primary connector, that has the same layout as a 20 pin connector, with four additional lines. It also ups the auxiliary +12V connector from 4 to 8 pins.  Again, the existing 4 pins are identical...it is just expanded. This is of course to accommodate the higher power consumption of multiple processors.

With modern processors dissipating 120 or more watts, however, even single processor boards are beginning to require more power. That is why many modern boards, especially with the anticipation of dual-core chips, are beginning to accommodate the spec. Adapters exist to convert the connectors either way, and many of the latest power supplies in fact come with a 24pin connector attached, and an adapter to convert to ATX standard 20 pin.

Quote
The basic ATX spec is 20 with an optional 4 pin +12v, while the
SSI spec is 24 pins with an optional 8 pin +12V.

It is entirely possible that the motherboard would work with a regular ATX
power supply. You would have to check with the motherboard manual to see if that is the case. The connectors themselves are electrically and physically compatibile--the SSI spec just defines additional pins. If they are absolutely required or not would be dependent upon the manufacturer; MSI states that you can use either a 20pin or 24pin with the Neo4, according to the manual. Should you choose to get an SSI spec power supply, yes, the EPS12V spec is what you are looking for. Antec makes a True550EPS12V if you're interested.

To further complicate matters, after looking at the Neo4, it uses a 24pin
primary plug and the 4 pin ATX +12V plug. Most EPS12V supplies (including the Antec above) come with the 24pin main, and both the 4pin and 8pin +12V auxillary connectors.
It is only with the heart that one can see rightly; what is essential is invisible to the eye.

mga veterans and mga ser! desperado din po ako! namumulubi ako sa pag gastos sa rig ko. ayoko ito masira! meron akong Dynamo 450w. hindi ko alam kung kaya nito ang specs ko. at balita ko nakakasira ng rig ang mga cheapy na psu!

axp 3200+,msi k7n2 delta-L, 3 x 256ddr pc2100, radeon 9550 ee, 20+10gb hdd, tt volcano 12, cmi soundcard, dvd rom, floppy, 1pc 92mm 6000rpm fan(intake), 1 80mm(intake) 3000rpm fan, 3pcs 80mm 3000rpm fans(exhaust).

ano po sa tingin nyo? at ito po rin ba ang dahilan kung bakit ang takbo ng proc ko eh 2.191ghz lang instead na 2.200+? kailangan ko po ang mga tulong nyo!

hindi ako sure sa mga P4 dynamo pero may mga nakikita kong users nun dito na naka overclock pa ang PC pero ok naman.

para sa akin. maganda mag invest ka sa mga mas kilalang PSU makers.

tignan mo sa bios yung FSB Spectrum seto mo sa 0 or disable. kasi baka naka 1%

one way is using a program, like everest, to know your current voltage on the 3.3V, 5V and 12V rails.

the acceptable deviation is +/- 5%. for example, the 12V rail, the values you should be reading should be between 11.4V to 12.6V. the closer the reading is to 12V, the better.

better PSUs have good feedback circuits and parts; better overall construction and parts for the sake of discussion; to maintain the voltage at the right levels.
I can see what you see not. Vision milky then eyes rot. When you turn they will be gone, whispering their hidden song. Then you see what cannot be, Shadows move where light should be. Out of darkness, out of mind, Cast down into the Halls of the Blind.

hehe, i have 4 fans and now its anoying na. an extra PSU will build more heat inside my casing so i never thought of getting a 2nd PSU, just upgraded my PSU to 450wats nalang
