MA785GT-UD3H - restarts and power off

[bpjl]

Hi.

Sorry for my poor English. My name is Laszlo and I am the owner of the MA785GT-UD3H. I have a problem with it for a few days.

Whenever I want to run a game or 3D Mark 2011 tests the computer restarts or power off. At first I thought the power supply fault. So I bought and installed a SilentiumPC Deus 600W 80Plus Bronze G1. Unfortunately, it did not help. I reinstalled the system and drivers - did not help.

Here's my setup and a few screenshots:
AMD Athlon II x4 630
Gigabyte MA785GT-UD3H
12GB DDR3
MSI GTX560Ti Twin Frozr II

GPU-Z:
 


AFTERBURNER:



CPU temperature after an hour of work at 100% load:



MemTest after a night of testing memory:


So I thought that my video card is damaged. However, when I inserted another card to my computer it still shuts down or restarts. Thats why I thing that mainboard may cauce these problems.

I might add that the problem was not before. About 4 days ago suddenly started to have problems.

Any suggestions? Any help?

What Revision is your motherboard?

Are you running the latest BIOS for it?

No offense ,but that power supply is a C.R.A.P.Dual rail poor design ,no Continuous power rating and strange name are few of the hints.
I wonder what you had before if you say this is a good one.

Get a real power supply and see what happens
Something like a Corsair 600 should be ok for that rig.

Revision is 1.0 and I flashed bios for newest today.

Earlier I had CHIEFTEC GPS-450 and as I say problem started few day ago. Earlier everything was OK.

Chieftec as a brand  is ok ,but the 450W  would not be enough for the system.Chieftec usually overrates the power by around 50W ,but otherwise ,electronically speaking, they are ok ,decent.
So the first was not enough as the second PSU that has 600W on the sticker only.

Get a good PSU and your problem should go away.

I guess I have to admit you're right.

I went with my parts to a friend and we started to test everything.PSU causing problems. At Be quiet! Pure Power L8-CM-730W unit, everything works perfectly.

Today I'm going to buy a new power supply. I wonder if should buy this one - Be quiet! Pure Power L8-CM-730W (I've tested my stuff on this unit and everything was OK. No hangups or poweroff). Or choose something else at a similar price + / - $ 120?

You should buy that as you ve already tested it ,but you can choose something similar quality wise.Corsair ,OCZ , Seasonic could be good choices in the ~650W watts zone.You need a power supply able to deliver 40-50 Ampers on the 12 V rails continuous having in mind the configuration you are having now and a possible CPU upgrade.
If you need a cheaper one Sirtec or Chieftec could be good choices ,but keep in mind they add 50W to the real power on the sticker,so substract 50W to get the real wattage.
