Dead PSU?

16 posts in this topic

Posted

Earlier today my PSU (Rosewill 630watt) appears to have died. it's 2.x years old as i got it sometime early 2010.

my CPU/Motherboard/RAM (ASUS P8H61-M LX Plus MOBO/i3-2120 CPU) i got May 2012 and everything has been stable so far until today when the PC turned off mid-day and the PC would not turn back on.

so is it safe to assume my PSU is dead?

p.s. i never had good luck with PSU's as in this same PC i have replaced the PSU once already and this will be the 2nd time (first PSU lasted from March 2006 til early 2010). but i am planning on getting a 'Seasonic 520w' which has a 5 year warranty for $75 out the door which is here... http://www.newegg.co...N82E16817151093

Wouldn't say for sure that its the PSU. If you can get another one, do plug it in and check if the computer responds or doesn't.

Seems like its the PSU but no way to tell for sure

Possibly could be dead.

First things first though obviously try a different wall plug and power cord if you can.

Then take the side off your case, with it plugged into wall, is there a light on your motherboard lit up even with the computer turned off?

^ As above, check for power lights on your motherboard. Is it at all possible to check the psu in another machine?

well there is no power light on the motherboard right now and it's plugged in.

only thing i have to test the PSU on is a motherboard sitting on my floor which is the old one i had replaced May 2012 with the current board. but that board (ASUS A8N32-Sli Deluxe) still works fine.

is there a way i can just plug in the power to the board etc just to see if it starts up WITHout installing it into a case since that would be a big pain to do right now since i would have to remove my current mobo?

Try jump starting the PSU: http://forum.overclo...hread.php?t=394

i just tried that and it appears to be dead.

just to make sure i did it correctly i had it unplugged and then had it (the paper clip(steel one obviously ;)) touching the green/black prongs and then plugged it in and nothing. then i even flipped the power switch a couple of times while the wire was there and nothing. then just to make sure i even had the power switch one way and then tried to do the paper clip as it was in one position and nothing and then removed the paper clip and tried the other position on the on/off switch on PSU and still nothing. so that should have covered pretty much everything you can try with that paper clip according to that article.

so it's pretty safe to assume the PSU is dead now?

and by the way... thanks for your time and everyone else.

p.s. i placed the order for that SeaSonic above in my initial post as hopefully getting a PSU with a 5 year warranty will finally give me a PSU that lasts but i have a feeling with my luck that eventually ill be making a claim on that warranty, lol. but supposedly the capacitors are of higher quality on those higher warranty PSU's?

If it doesn't jumpstart using the paper clip method, it's more than likely dead, although off I were you, I would still try a spare psu on the newer board just to make sure there's nothing wrong with the system, that is, if you have a spare one to test with. Sounds like it's history to me though. (The psu, that is) (Y)

Whoops...*IF I were you...auto correct got me, lol

Could be the fuse inside the power cable or the PSU that's dead.

A 2 year PSU should NOT be dead unless it's a very cheap one.

Rosewill is about the cheapest you can get, n_k.

Yeah, thats the best option is to test with another PSU but i don't have any other one to try otherwise i definitely would just to make sure the system is stable etc.

technically i got another PSU but... it's powering a old Athlon 1.2ghz (the PC i am using to type this) which obviously won't work with newer style boards.

but anyways... is it uncommon for a PSU to fry the board (and other components) when they fail? (i have had 3 PSU's die and, so far, none harmed my motherboard or any other components)

Yeah, it was cheap at the time as i needed something cheap but provide decent stable power and that was basically my best option back then.

but since it only lasted 2 years and some odd months it just goes to show it's pretty low quality in terms of it's longevity and this new one (SeaSonic 520watt) should be much better due to 5 year warranty.

p.s. i do leave my PC running 24/7 though.

My Seasonic 550W has lasted me 3 full system upgrades. And still works like a champ.

Leaving your computer on 24/7 does not really matter.

yes, it's pretty uncommon, but you know, just to be sure and all never hurt anything....but I'm 99% positive that just the PSU was affected, by the sound of it. (Y)

Well i just got the PSU (Seasonic 520watt) in today and i just finished installing it not long ago and so far so good as everything starts right up and so far everything seems stable as ill probably run a Prime95 test and FurMark test on it for CPU/GPU stability etc.

but anyways... thanks for everyone's time. i appreciate it ;)
