Well i just assembled my computer and something went wrong. I turned it on, and everything would power up, fans would move for like half a sec then turn off. I didnt know what was wrong. I double checked everything, and everything appeared to be right, and i asked people what to check and i checked it all and double checked it. I then figured that my mobo, processor or power supply was bad. So i tested my mobo with another person's power supply and same thing, then i tested my psu on their mobo, and it worked fine. So i figured the mobo was the problem. But just to be safe i sent the processor and mobo back for new ones. I just recieved the new mobo and processor should be back by friday, or sat.
However, some new information came to light. I have the new K8N Neo4 platinum mobo from MSI, and apparently it needs an atx 2.0 power compliant source. I have the thermaltake W0014 480W source, which is not atx2.0 i believe. So does this sound like the problem, should i send my psu back and get one that is atx 2.0? Plz respond need help!!!!

This is a link to a new psu im thinking about getting...is it atx 2.0 compliant, i think it is but want to make sure. And just in case i am running the amd64 3200 processor. Thanks for any help..

ps. i just found out that apparently my psu is 2.0 compliant from this link, what are your thoughts everyone?????

well i just found out that link i had for the supply i was thinking is exactly the same one i have, just that tigerdirect says it is 2.0 compliant. So i dont know, what should i do?? anyone know what my problem is???help needed plz
 
1. symptoms described can be from multiple causes, power is one of them, but the others would be
a thermal cutout, mobo isnt reading a CPU heatsink fan and is shutting down do to "fan failure"
ensure the fan is plugged into the right header on the mobo
its shutting down because the CPU is getting too hor,
ensure the heatsink is properly seated and the thermal interface material is properly applied

2. ATX 2.0 is a mobo spec
ATX12V is the subspec for power supplies
the latest two are ATX12V v1.3 & v2.01
a supply outputting sufficent amps per rail for your config from either spec will work on that board provided there are the correct connectors, connectors alone arent an indication of the compliance to one spec or another, basically an ATX12V v1.3 supply will have a single +12V rail, natively under the spec it has a 20 pin main power connector and a 4 pin +12V auxillary mobo connector
ATX12V v2.0 will have dual +12V rails and natively have a 24 pin mobo connector and a 4 pin auxillary connector

there are many hybrids with a single +12V rail and a 24 pin + 4pin connection
there are even ATX12V v1.3 supplies with EPS12V connections (24 + 8 pin) one is running my sig

3. you need to determine the amps per rail your config requires
watts mean little these days

if youd post your config Id give you a hand
include everything that is drawing power ;)
(all fans, lights, buses ect)
 
well just to let you know, i tried the power supply on the mobo with just the ram and processor and essentials connected. but i will list everything that is going to draw power.

amd 64 3200+ socket 939
MSI K8N NEO4 platinum
corsair xms xtreme memory 1 gig 2-2-2-5 ddr pc3200
seagate 200 gig sata 7200 rpm
sapphire x700 pro video card 256mb
NEC 16x dual layer dvdrw
4 case fans 80mm
zalman copper heatsink with fan
sony floppy drive
dragon case

i think thats it, let me know if it sounds like im missing something important, thanks for help. And my power supply is already listed too, so you should know everything..
 
OH, and im almost positive that the heatsink was on there correctly and that the thermal compound was applied right, and i am positive the fan was plugged into the right part, the cpu fan slot on the board, pretty hard to miss. But thanks for the help. And plz help out with probs, thanks again.
 
are you plugging a 20 pin ATX power connector into the 24 pin connector on the motherboard?? if so, make sure to plug it in so the hook DOES NOT line up with the catch on the motherboard. It will stay connectected provided you seat it all the way in. It's best to use a native 24 pin power supply with these SLI boards, but my a8n worked with the old fortron 530 plugged in as I described. but it's soooo much more stable with the new antec TP 550 eps.
 
my motherboard is not sli first off, but the board does accept either the 24 pin or 20 pin connectors, it doesnt matter. And my power supply came with the 20 pin to 24 pin converter and i tried it both ways so i dont think that is the prob. ANy other suggestions? Ice czar did u look over my stuff, what do u think????

your problem is a lack of amps on the +12V rail
that supply is rated for 18A and thats before applying a derating curve for temperature which in the case of TT
Id say to be about 1\3rd making it effectively 12A

whereas refering to the link above your theoretical maximum is 21.1
but a real world worse case senerio would likely be about 18A

you need to upgrade to a new supply either an ATX12V v2.0 cheap seats being the Fortron Blue Storm, Higher priced the Antec Neopower
or a more powerful ATX12V v1.3 supply w\ the 24 pin connector
Powerstreams are nice
sort of depends on what your budget is like
that supply simply predates PCI-E and doesnt stand a snowballs chance in hell of powering that config

ThermalTakes arent all that highly regarded around here, not that they are "bad" just overhyped, more flash than go, just basic spec compliance and industry "typical" exaggeration of capacity and amperage
 
The power supply has enough power. Trust me. It sounds like the motherboard is grounding out to the case. Try taking everything out and assembling the componants on the motherboard box and start it by shorting out the two power pins on the mobo. If it starts then, it's grounding out to the case.

horse hockey :p

CPU = 7.4A
GPU\PCI-E = 6.25A

while the mobo could be grounded and thats good advice ;)
that PSU isnt up to a PCI-E AMD64 config
total wattage doesnt mean Jack these days
that config could easily be powered by a 350 watt supply

if the amps are on the right rails
the point is they arent
 
your not running 6.25 amps of +12V through a PCI-E bus now are you?
a fairly healthy portion of the power driving your card is coming off the +3.3\5V rail
 
well i tried taking it out of the box to see if it was grounded to the case, and it still didnt work, did the same thing.
Good news is that my buddy has an ocz powerstream 600w, very nice, that should more than power it right?
 
definately overkill almost :
make that room for that 6 drive RAID array :p
 
well i have some new info to post. I plugged in everything, except the cpu because my new one comes monday, and everything turned on fine, worked great. And this is using my thermaltake psu, so does that mean that i should be good when i get my cpu, and that if it doesnt work, then just use the better psu. Because i know everything i have in there now works perfect, the diagnostic lights tell me the problem is the cpu is in wrong, but that is because its not even in. So my mobo and everything is working, but when i put the cpu in, will it draw so many amps that i will need a different psu, in this case it will be the ocz, but is that what that means?
 
nobody answered my previous question...could someone tell me that since my mobo and everything is working fine now, that when i add the cpu, will that draw so many amps, as for the power supply to not be able to provide them? plz answer if u could, i have had many different opinions
 
your CPU is the single most power hungry component you have
and you can likely plug that in and start up as well

but likely not without eventual issues
beacuse all the components are dynamic in thier power consumption
the supply reacts to that and converts power (AC>DC) as required
its total capacity for your config isnt high enough given your likely operating temperature

shadowbreaker513 clammed up as soon as I pointed out you where running a PCI-E config and he wasnt

you want a high quality supply with a minimum of 30A on the +12V rail(s)
(and 18A aint goin to cut it for reliable day to day operation, especially when that rating was likely done near 25C)
 
will my comp be ok running this psu for a week or two though, just until i can get that ocz powersteam?
 
maybe, maybe not

I have no real idea what the "idle" draw is like on a PCI-E card
but it didnt work the first time did it?

the colder you can get the supply the more capacity it will have
peg your CPU & GPU though your going to have a problem
so ...no gaming

then of course things could go wrong with an overtaxed supply and end up frying components
 
well i put my new cpu in and the same thing happened, it would turn on for like half a second then turn off right away. So my power supply just simply cant handle it right? And i took your advice and ordered the Antec Neopower, that will power it no problem right?? Please let me know if i am correct in my assumption, because if this thing doesnt fix my problem, damn i will be mad.

yup Id say it simply doesnt have the juice to run that config, even for a startup
the Neopower has 30A across the dual +12V rails and will power it no problem

in the meantime if that board has onboard video or you have an old PCI video card youd likely be able to run that once you pull the PCI-E card that is
pill the PCI-E VideoCard and I bet it will fire up no problem :p
 
my board doesnt have onboard video, and i dont have an old pci card, and i tried starting without the video card and nothing happened, is that normal?

only if there isnt enough power to start or unless something is fried of course
otherwise it should beep like crazy because there is no card
just like if there is no RAM
well that is true of AGP based boards, I havent played with PCI-E boards



correction > the Neopower has 33A (18\15) on the dual rails
 
well the new power supply did not help the problem..................however i did solve the problem, when put the zalman fan on, my friend who was helping me(suppossed to be the computer guy, but everyone makes mistakes) did not inform that there was suppossed to be cardboard washers inbetween the mounts and the motherboard. This was shorting it, and thats why it was shutting off, but i am up and running and the comp is working great, thanks to all who lended support.
 
so it was only shorting with the CPU installed? :p

generally there arent any washers between the mobo mounts and the mobo
the holes on the mobo have a metal ring, and as long as the mounting pegs (typically brass, pressed steel or plastic which is non-conductive anyway) arent touching any circuits outside that ring your good to go.

the most common reason for a mobo short is a mounting peg that isnt supposed to be there,
not lining up with a hole and contacting a circuit on the back of the board

I always startup my new rigs in the cardboard box with just a speaker, CPU and Heatsink and go for alot of beeps :p
add in the RAM AGP keyboard and mouse and access the BIOS

then I mount the mobo and repeat, if successful I start adding drives and cards ;)


what supply did you get?
 
i got the neopower, it is working great, i already have everything up and running, next i have to learn how to overclock....that will come soon, thanks for help
