Power Supply Upgrade/Problem

Hi everyone.

My original problem, i am sure is my power supply. However i would love a second opinion.

I have just upgraded to the cross hair V main board. My computer has been restarting randomly during intensive game play. it didn't do this before my upgrade. my PSU is 500w but ridiculously cheap.

Would you say it's the problem?

Secondly as i have said above i currently have a 500w PSU. I am thinking of upgrading to the antec High Current Gamer 750 watt.

I have filled in the system specs. do you think it will run my computer perfectly. also i will be getting 16GB DDR3 1600MHz RAM and an ATI 6970 will the antec PSU be enough?


I have done researchantec PSU seem's good but - recommended PSU for gpu is 750 and i think my mainboard is 600 so i arn't sure if i'm meant to add them up or just go for the 750.

Thank you all
I have tried multiple PSU calculators and found them to be shockingly awful

It seems to me that without alot of peripherals a 500 watt should be fine. I never 'cheap out' on hardware so I wouild recommend Antec or Rosewill.

As to the random restarts it could be a PSU but I wouldn't rule out other issues such as heat.

cheers for the quick reply. I have been upgrading in a funny order. Instead of getting the PSU first i got the processor then the board. PSU on thursday and then hopefully i can game again :)
Dont think colling is an issue though rarely gets above 50c.

Why you don't skimp out on the PSU,

Just because it says 500W on the label doesn't always mean that's what it can output.

Get a Seasonics modular 650W or above. It may not be your problem but it will be eventually.

What does that mean? A motherboard is not going to use 600 watts.
