Title: computer restart for no reason - suspect PSU problem Post by: CounterStrike on December 08, 2013, 02:38:42 PM Guys,
I have been using cgminer mining with 3 GPU (R9 280x) for about 3 weeks with seasonic 1000watt platinum PSU. But today it just restart my whole comp immediately when I start mining with 3 gpu but it work with 2 gpu. I only draw 780 watt from wall with 3 GPU so power isn't the problem. What can it be? Thanks... Title: Re: computer restart for no reason - suspect PSU problem Post by: vm1990 on December 08, 2013, 05:44:25 PM heat?
or the motherboard cant handle 3 cards. try 2 gpus and if it stays stable for a day or 2 then its either a dodgy card or more likely the motherboard or PSU is having trouble keeping up with the gpus Title: Re: computer restart for no reason - suspect PSU problem Post by: zhinkk on December 08, 2013, 07:28:52 PM That does sound like a PSU problem. Is there another high wattage PSU you can try in that system?

I would suspect the PSU only if it resets when the PSU is warmer like mid-day since it will draw more watts at that time. My 4 card rigs would swing 50 watts depending on the time of day. |
