Failling power supply

post #1 of 6
Thread Starter 
Here is my problem, my computer will sometime fail to post and when it doesn't it will often lock up shortly after finishing booting.
However, if I boot into safe mode and give my computer about 10 min to "warm up" before rebooting then I won't crash for as long as I keep the computer on.

I'm thinking my PSU might be on the brink of failure, any advice before I pull the trigger on a new one. I'm currently looking at the Corsair HX850.

Your PSU is an old Super Flower its not made by Xion

And you dont need anywhere near 850 watts yet alone 1000 watts

550 watts is all you need if you have one video card

I'm thinking of adding a second 7970 very soon, which is why I want a 850W PSU

EDIT: I still have the box for my PSU and it clearly says XION on it.

It's the AXP-1000P14HE

Yes but your PSU is not made by Xion its a Super Flower PSU

The HX850 you want is not made by Corsair either

You dont need 850 watts even for two cards

Other than at then end when he says a higher wattage PSU is just wasted energy going in the PSU its pretty accurate.

In fact a 850W under a 700W load would be more power efficient than a 750W PSU under the same load (if both have the same 80 Plus rating)
And I like having the head room since it also means the fan wont run as loud.

No he got the part about efficiency wrong

If you want an 850 despite its more then enough you can get better then a HX850
