Computer won't post after circuit breaker tripped...

[JBourke]

Hi guys, this is kind of a long story...

About 3 months ago my computer wouldn't turn on after moving into a new apartment, I took it to a technician and he confirmed either the motherboard or the CPU was faulty. I figured this was probably normal since it was almost a 4 year old gigabyte motherboard. I replaced the motherboard and CPU and things have been running great for a few weeks until this morning.

I noticed that none of the outlets on the left side of my apartment were working, so I reset the breaker and plugged everything in. The minute I plugged my computer in the breaker tripped, now my computer won't post at all in any outlet in the apartment.

I am so frustrated and dumbfounded at this, I hope my new components aren't fried. I'll post my setup...

Asus Z87-Pro Motherboard
Intel i5-4670k
OCZ Modxstream Pro 700w
Gigabyte GTX 460 1gb
Hyper 212 Evo CPU cooler
Antec 300 Illusion Case
Samsung Spinpoint 500g HDD
Sony Optiarc Disk Drive

I would suspect the PSU.
Would recommend buying a cheap PSU tester, Disconnect ALL connectors from the PSU and plug into tester and try powering on, If it still trips circuit breaker - PSU is Bad, If it does power on then ?? does it pass the PSU test.

NOTE: passing a psu tester is NOT a 100% "good to go", just a warm fuzzy.
Your PSU is listed as a tier 3 PSU, But personally I've never bought a OCZ PSU and never would - they do have a few that are listed in tier 1 and 2.

And Yes if the PSU is bad it could have taken out any, and all, components connected to it.

PS - As a matter of course, I would have replaced the PSU when you replaced the other components.

I brought it to a repair shop (as this seems out of the realm of my knowledge) and they were able to get the motherboard and fans on with a separate PSU, (got a d7 debug code on the asus motherboard) although the computer itself won't post (although it was just a quick test). Is this a good indication that my motherboard is fried? I know i'll get an answer regardless in a matter of days but I want to start researching different parts to get.

I'm thinking the PSU is fried and either the GPU or the motherboard...

Any PSU recommendations? I also now want to invest in a surge protector...

http://www.eggxpert.com/forums/thread/323050.aspx is what I've always used as a general guideline, Seasonic and Corsair being ideal brands.

It's better to wait for the definitive answer from the person who is physically handling your PC. We can only speculate as to what may be the problematic / damaged pieces.

Really not going to try to 2nd guess status of MB ect - Requires checking.
On PSU, Your system, with a mild OC say upto 4.2, 4.4 Ghz and upto a 7850 gpu will be under 300 Watts.
My system: i5-2500K @ 4.2, w/7850 GPU, 12 gigs ram, 2 SSDs, 2 HDDs plus a Blu-ray burner is ONLY about 200 Watts.
@50 watts as measured at the wall outlet.
I only recommend Tier 3 and above, ig possible I go with tier 2.
Min PSU Silverstone 450W:

or
Seasonic 430 W: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151074

Little more head room:, go with 500->600 (500/550 max, 600->650 Max if planning on Xfire or SLI w/2 gpus up thru 78xx series)
520 W Seasonic: http://www.newegg.com/Product/Product.aspx?Item=N82E16817151093
600W Silverstone: http://www.newegg.com/Product/Product.aspx?Item=N82E16817256071

For other choices here is the "tier List": http://www.eggxpert.com/forums/thread/323050.aspx

Added; (biopolar) reference Corsair - Yes they make some excellent PSUs, the TX and HX followed by the GS series. I have the corsair TX650 in one build. The CX is a tier 3 PSU which is in my "acceptable list", but personally tend to go with a higher quality. biopolar - I see you have the cx750 so please no offense.

Is there any ramifications for having too much wattage? I want to upgrade to a GTX 770 or a 760 (perhaps Volcanic Islands GPU when they arrive) in the future so I was thinking of getting a SeaSonic X Series X650 Gold http://www.newegg.com/Product/Product.aspx?Item=N82E16817151088. I don't plan on SLI or crossfire, but I do want to overclock my CPU and GPU.

I keep hearing Seasonic is an excellent PSU brand and I don't really want to mess around with a PSU that may be faulty in the future. I'm thinking the PSU caused my first motherboard to fry and possibly caused what is happening now.

The 650 Seasonic is an excellent choice.
The only downside of a "Large" PSU is when at Idle if Your power consumpution is less than approx. 20% the efficiency drops off - SO REALLY no Biggy

'personal experience' bought a logitech 550 watt psu for first build. pc would shut down under load- replaced psu with corsair tx650 works bewautifully but when i began thinking of sli'ing a couple 770's i was forced to change once again. now i run a 1000w modular ocz 80+ gold psu . moral of the story is A) dont buy anything cheap and expect it to perform. B) and most important, make sure your psu will handle your current and future needs. i could have used the @250 ive spent to buy a fantastic cpu and still have some left for fun tickets.
