Need Help For Smps Power supply problem with 5 Hdd

I have pentium 3.00 with 5 Hdd and 1 dvd writer
Many times computer wont detect Hdd attached to raid card

i have 4 hdd attached to raid card , sometimes it detects 2 or 3 hdds only . sometimes all 4
but all hdd is working properly so there is 100 % no problem in hdd
some times it wont detect raid card also , if it dont detect raid card i open cabinet and remove the card slightly and then push it agian .

i want to know whether mine power supply or Smps is enough

i have Zebronics 400 W power supply . i think it is for 600 - 700 Rs

Question is should i get new smps and if yes for how much watts
Like 500 watts true power or which one

Your Post is in wrong section.

BTW did you tried connecting all the HDD's without RAID Card or with a different PSU ?

I know the PSU is a bad, but to handle 5 HDD's, IMO it should work fine.

Anyway check what i mentioned above & post the results.

Pentium 3 motherboards are known to have problem to detect multiple HDDs and if the HDD size is higher than 160GB. Also 400W PSU is little underpower to power 5 HDDs along with other components. Get a 600-700W local PSU from Foxin, intex or Frontech, price will be within 700 to 900 bucks.

Problem is with your mobo, not with PSU. (assuming that you don't have graphics card or sound card(s) )

why problem is with motherboard

i tried to remove 1 harddisk and it detects harddisks many times .
and i tried to remove any one hdd not any specfic one
i think should i go for higher smps or not

also i cant connect 5 hdd to motherboard without raid card as motherboard has only 1 ide port.
i don't have graphics card or sound card as it is builtin on motherboard.
i have 2 gb ddr 2 ram.

Speedfan shows this . can any expert tell me is power requirment low as it is 400 W Zebronics .

vcorea 1.36V
vcoreb 1.52V

+ 3.3 V 3.33V
+5 V 5.08V
+12 V 12.28V
-12 V 1.95V
-5 V 2.80V
+5VSB 5.59V
VBAT 3.20V

You have already got your answer. Your motherboard is too old to run 5 HDDs without any problem.

50 % times 5 Hdds runs without any problems . if i remove 1 Hdd 70 % times no problem. if i remove 2 Hdd then no problem at all .

mine is 915 Motherboard

i want to know is Zebronics 400 W power supply enough

^^
Bad PSU. But even then your board would not support.

I was asking which smps to buy
400 w or 500 w true power supply - vip brand - it is above Rs 2000

A

board is supporting sometimes like in 10 times start it is supporting 7 times all 5 hdd
but i think when there is power problem the computer after starting windows disappears any one hdd

Speedfan shows this . can any expert tell me is power requirment low as it is 400 W Zebronics .

+ 3.3 V 3.33V
+5 V 5.08V
+12 V 12.28V - now it shows 11.05 or 11.31 many tims

And your budget for buying new PSU?

P.S. don't go for any cheap brand like vip.

no graphics card and no sound card

NO I dont think so , mine motherboard supports 6 HDDS

Listen to him.

no he is wrong

.
only 1 thing i dont understood
Enhanced dual +12V output capability - it has 12V1 and 12V2
how to connect that
i have connected main powersupply 20 pin into 20 pin and 4 pin motherboard cable to motherboard . now where is that 12V cable to connect .

A

now everything is ok
i have put 6 hdds (includes sata hdd also) and changed the power supply
power supply was giving problems not motherboard

so the suggestion was wrong for changing motherboard .

^ as mentioned earlier.
