[wiz_heero]

Hello guys, I need some help here I build a new system and its running smoothly then my PSU 500w got burned I change my PSU to 650w,the system running smoothly again. i change my os to window 7 its perfectly running. in the middle of nowhere the system shutting down, i need to turn on again to power up the system. what do you think the problem? hardware or sort of software that running in my system?

MSI 890FXA-GD70 AMD890
AMD Phenom II X4 955 BE
HIS ATI Radeon HD5770 1GB 128Bit GDDR5
4GB DDR3 1600 G.Skill RipJaws Dual CL9
500GB WD Caviar Blue 16MB SATA
Tornado 650w

maybe something is over heating or its power supply

What are your temps? run a benchmark program and monitor your temps while at 100% cpu load. That way you'll know if it's a heat issue.

 

[micropage7]

usually it related to heat, if it shut down, does it need a time before you can trun it on again, if yes. i guess its caused by the heat
try to check the fans, the hsf and make sure all connected and run well
does it bsod sometimes too?

 

[wiz_heero]

i already monitored the system temps gpu temp 46°c cpu 39°c - 53°c chip set 35°c - 47°c

the only program running in that time when the system 1st shut off is plants vs zombie.. hehehe...

Well, can you link us to your power supply? It probably might not be the problem, but unknown brands/crap quality power supplies can cause this to happen. Tornado seems like an unknown brand.

 

[wiz_heero]

Yup tornado is unknown brand, the 1st PSU that i have is tornado 500w... where suppose the problem? guys do think the cause of the shutting is my motherbaord but the system runs perfectly...

It's most likely the PSU. I'd replace it with a better brand. Corsair, Seasonic, Cooler Master, OCZ, NZXT, and many other main name brands in the market will be worth your money.

 

[1nf3rn0x]

It would be good if you could open up your computer case and write all the numbers listed on the side of the power supply. A good brand power supply is a must. Corsair, Seasonic, OCZ, Thermaltake, XFX, Gigabyte, Antec etc are all good brands for power supplies.

 

[wiz_heero]

thanks guys... i check it later... ill make some test run, i will update you guys...

 

[Radical_Edward]

Also great recommendations, thank you 1nf3rn0x.

That is what i was about to say , so yeah! right down how many amps it gives you on the 3.3v , 5v & 12v

some budget case packed with generic psu, it built using cheap stuff and we know some generic performance is 'like that' so you shouldnt expect so much on its reability and power, especially if you run your rig extensively and on heavy task.
If youre on budget and your rig just run for daily use and you stand the rig on standard i guess 500watts is pretty enough

I runs some sort of tested yesterday...

1st thing happened when i 1st switch on the avr no power in the avr, then i change the fuse in the avr and switch on, switch on the system after 5mins the system turn off again. its happened 3times, and i enter the bios after i saved the setting the system power off again, its happened 2 times, and the 3rd times the system power aff again and automatically power on and after 30mins its power off again, i transfer the power cord into another power socket, system runs 1hrs without shutting, after that system power off again.

this morning I tested the system again without using an avr the system runs fine an hour but i need to shut it down. later I check it again

thanks guys...

 

[silkstone]

definitely sounds like the psu can't cope. either that or you don't have a very stable electricity supply to your house

Also, load the bios up and look at what your temps are.

Voltage reading

CPU Vcore - 1.400V
3.3v - 3.344V
5V - 5.087V
12V - 11.704V

Side panel of PSU Voltage

+5V = 45A + 3.3V = 26A

+12V = 20A + 12V = 2.0A

+5VSB = 2A + 5V = 0.1A

 

[wiz_heero]

Guys thanks.... i already fixed the problem... i changed my PSU, AVR and fixed the electrical wiring...

There is a great PSU guide in hardware section of this forum. Take a look at manufacturers and buy one. I had a PSU problem until I changed to Corsair XH 620W. If u want to check your's rig stability, especially the PSU, I recommend stressing your PC with prime95 and furmark at the same time (stress your CPU and GPU at the same time). When I did it with my old 500w PSU by unknown manufacurer after 15 mins I started smell burning from my PSU and then it shut down immediately.
