psu is faulty! Do a RMA

 

[MUZAKKIR]

is there any compatibility issue with motherboard

 

[erocker]

Recheck all of your connections. If they are good and the problem persists it's a faulty PSU. Yes, yours and any other ATX standard PSU is compatable with your motherboard.

Problem occur after i installed gfx gts 450 but when i remove it from slot then still there is problem so i should rma it

Check if you have plugged in properly first, I thought my Coolermaster Extreme 460W was junk but it turned out the extra 4-pin plug to the motherboard was not connected properly (although the on switch is pretty faulty because once you turn it on, you can't turn it off back to the O )

 

[MUZAKKIR]

so what do you think is the problem with mobo or psu

 

[Jetster]

You guys just to conclusions too fast. Take it apart and start testing. First the PSU. Just short the green and black and plug it in. Google the wires to short just incase there not green and black and then do a bench test with just the basic parts. You probably have a short or the HS CPU is not seated correctly. however that PSU is known to go bAD

For us to know if it is the motherboard, it might be a good idea to post the actual type you have. This sounds vaguely like a P5 reboot issue.

i hv dg41rq

i hv dg41rq

Ah, I didn't notice that that weird string of characters was supposed to be a motherboard model number.

Anyway.

First try resetting the CMOS. Then, try booting with only 1 stick of RAM and disconnect everything else except for the optical drive. If that works, add your HDD and see if you can boot to your Operating System.
Then, add the second stick of RAM. Keep adding components until it fails again.

Hi

It may be the onboard VGA, if the issue occured after fitting the gts 450

did you remember to disable your onboard VGA? settings are in your bios. when you fitted your gts 450, you will have needed to boot to your bios setup and disable the onboard.

reset your bios and try again

use a different powersupply to make sure everything else then the psu is 100% working! then you may upgrade or do an rma

 

[micropage7]

try to unplug the psu and leave a while
then re plug it again and check all the connection
but it looks your psu is bad, usually it happens on shortcircuit condition
so better re check again, if you aint move or add any hardware in your cpu, i guess the problem could be from your psu
if that just RMA it

i hv already select auto detect opt for gfx and listen when i plug my old unbranded 450w supply then the system boot fine can u tell me how can a reputated brand like corsair give me a bad psu which i bought yesterday

It happens all the time. You get PSU's, HDD's RAM, CPU's all from reputable brands but turn up DOA. It's just a luck of the draw and completely normal.

When you turn the PC on and it turns off; does it turn itself back on afterwards?

 

[MUZAKKIR]

so thats the problem with my psu

 

[scaminatrix]

Don't know. It could be this:
Say, for example, that your mobo or GPU is defective. Your new PSU has protection built into it which shuts it down when something becomes unsafe. Your old cheap PSU doesn't have this protection. So it could be a defective component triggering safety protection in your PSU.

When you turn the PC on and it turns off; does it turn itself back on afterwards after 5-10 seconds?

 

[MUZAKKIR]

no it does not turn itself back but u say that it could be mobo or gfx when i run my system with unbranded ps then everything work fine

 

[scaminatrix]

First thing you should do is test the PSU as Jetster said. Remove all PSU connections from your PC (very important) and unfold a paper clip.
Turn off the PSU at the switch/wall plug and get the 24-pin motherboard connection. Stick one end of the paper clip into the green wire. Then stick the other end of the paper clip into any black wire.

Turn the PSU on at the switch/wall pug and see what happens.
If it stays on, then it's working. If it shuts down after a few seconds like before, then it's broken.

Remember to remove all PSU connections from the motherboard (if you leave the 4-pin CPU connection in you will fry your CPU. If you leave the 6-pin plugged into your GPU, you'll probably fry that, etc. etc.)

You can go here for the whole guide.

interestingly enough I just had two corsair psus that had to go back for rma (purchased 2 weeks apart). I could power them on using a paperclip but they wouldn't power on a machine.

 

[MUZAKKIR]

i hv plug my psu in another machine and same problem occurs so its definately my psu now i will send it for rma

 

[MUZAKKIR]

so its the psu guys

 

[xBruce88x]

yea i've had bad luck with corsair units... picked one out for a friend of mine, the thing died after a week. i since replaced it with a cheap iMicro 400w psu. been running fine for a year or so now.

 

[MUZAKKIR]

hey tell me is this faulty psu
