Hi guys

I have a question for you, I built a computer and I noticed suddenly shutdown of my computer all the components running ok.
My system
Asus rampage extreme lga775
Qx9770
Ddr3 1600mhz x4
X2 Hd4850 x2 2gb
X10 120mm fans
Is it possible that the power supply isn't powerful enough for my system?

I wouldnt say 1050 is double what you need, but you certainly don't need a 1000 watts. A Corsair TX750 or any quality 750W PSU should do the job fine.

I also thought this power supply will do the job but why some reviews on line says that 2x hd4850 x2 2gb crossfire setup will draw up to 800w together without the other parts.
The processor is 130w that's all ready 930w the rest for motherboard ,memory 120w left .Or maybe my north bridge was getting very hot because is water cooled i can't monitor the temp.

Just did a little research and those GPUs are POWER HOGs, using close to 390 Watts each at full load. Also they are OLD, since they are based on GDDR3 memory, which is super slow for modern titles. You do need a 1000 Watts PSU, and you need to work to invest in a newer GPU. Your TWO HD 4750 x2s, so basically four GPUs, have the combined power of a modern day HD 7770 Ghz Edition. A $120 card, plus that HD 7770 is a GDDR5 card, which will make it even better. Also that HD 7770 only uses 80 watts...

XFX 1050W PSU.

Expensive as all get, you might be better trying a new PSU and GPU combo.

Thanks for your help guys

I'm thinking to upgrade the gpu I have the power supply already hopefully I can sell the hd 4850x2 2gb and also the water cooled northbridge need an upgrade.

Thank you for everything guys much appreciated
