PSU's keep burning out

[jaybee]

I'd replace the mobo. I'd put money on it being that.

The Case is an Xblade with the PSU at top

Hello Summermoon,

I used to have a problem with quality/branded PSU's dying a lot after approx 12-15 months of 24/5 useage, they were all fitted in an older Chieftec Dragon (full tower jobby) with the PSU mounted at the top of the case!

It's not something I can prove but I have a strong hunch they all over-heated and slowly became faulty? . . . seems like a design flaw if you ask me having a PSU mounted directly above a possible hot running CPU and exhausting a lot of the system heat? . . . . since then I've used a bunch of Antec chassis's (P180, P182, 600, 300) which all have the PSU fitted in the lower part of the case and so far so good . . .

I remember being suprised the first time I placed my hand behind the PSU outake fitted at the bottom of a case and feeling cool air blowing out . . . up to that point I had only previously felt warm/hot air coming from a PSU!

Well Got my new PSU HX-850 and fitted it this morning, PC's still running fine. 9 Hours and counting running 3d Mark Vantage on continuous loop. Should bed it in nice.

Electrical smell has gone too now

Not using the surge protector. Too scared to now lol.

Checking the Corsair Forums it seem a number of peeps have been having the same problems even with the PCi-e cable!

Someone asked for numbers - which numbers ? volts, amps drawn etc., not sure what your after.

New MB - RMA Asus - OMFG the last RMA I did with them took 18 months!! and 123 emails only to be sent a replacement with a warped board!! The next one arrived a month later and work TG!

 

[Summermoon]

Left it running overnight all ok but the electrical smell is back!

I had a Corsair PSU go with an ear popping bang upon switching on the wall socket a while back. Some water might have got inside or the wall socket was dodgy, no evidence could be found of either though.
If in doubt, get an Enermax.

I still think its the motherboard. Asus claim to have improved their rma process recently, perhaps they have. I'd suggest buying a new board, not made by Asus, installing it then submitting the Asus board for rma. Sell the replacement on when it arrives in six to eight months.

Expensive, but motherboard failures often are. You'll be unhappy if the new corsair dies in a couple of day. Burning electrical smell isn't a good sign.

I know Westom loves data, but a cpu destroyed when a power supply fails definitely suggests that the motherboard connecting the two is likely to be damaged. Deductive reasoning > measuring everything imo.

Thats not good, I would rebuild your pc again,, cos sounds like somethings shorting or a bad component.

i think PSU just die randomly...

i mean i have lived in 3 premesis and between them i have lost (over last 9 years)

400w Antec
580w Hiper R Modular
520w Corsair HX

one at one home, one at uni and one at my new house...all on different mobos...im hoping my 600w bequiet does a better job.

 

[thingemajib]

but the switch over from mains to batts may not be quick enough to stop surges getting to your equipment tho, but it must be fairly quick for the pc not to die on switch over??

capacitors are your friend when it comes to switching power sources

That's so weird, as there are others that have never had one fail like myself. Including the cheaper brand ones. In fact I have to chuck them as they often last too long.

The modular Hiper psu's were notorious for having poor quality capacitors that would just go, often taking everything with them so not a surprise there

Well its still going strong even restarted it a few time and seem ok.

Corsair say that the adhesive used with the Capacitors is the cause of the smell!! New one on me but hey.

IVe started an Overclock and its up to 4Ghz and running it full power. PSU drawing 655 - 703watts at present (3 GFX in SLi too) just to see if it will break something or flush this mother board out

Im so FO with it.

Won't be taking the wife out for dinner for a few months if it goes and I NEED an new I7 980x!! (Dreamer)

 

[Summermoon]

Well I guess alls ok now. Backed the OC down to 3.8Ghz as out side temps are getting hotter here (75.C)

The surge protector is the culprit - Pluged my printer in and started printing POOF! Printers dead! Though only a dead fuse. REplaced and it went again. So much for the protection when it alone destroys stuff!!

Intelli Panel from ONe click - you'll be hearing from me soon.

Thanks for all your help guys and some good learning material on UPS's

Glad you got to the bottom of it. I have a thread all about surge protectors and how useful/useless they may be. A quick search of the forum will find it if you're after more info, though beware, it's a long read.
