Upgrading from 6850

[tristan]

my friend had a 1000 watt ocz psu which probably was never pushed over 600 watts and it died after 2 months, it might just have been bad luck but as i said a lot of people on this forum have had bad experiences with ocz.

Took the PSU's case off and it looks to be a true 4 rail PSU... Unless I can put 3 of the 12v rails onto the 7870's two connectors I'm going to return it.

IDK why I listened to the sales person. He didn't even know what micro-stuttering is...

Hope I'm wrong though.

if you can buy a xfx psu. they are made by seasonic, and they only have one rail, so it doesnt matter what you plug it into.
something like this will be fine

Not looking forward to the hour drive back to microcenter but its worth it.

If you've opened up the psu it normally voids the warranty so idk whether youll be able to return it. Then again it may be different in the us

You're right; however, with a heat gun and some other stuff the stickers are back on and you can't tell it's been open.

hmmmmmm fair enough then

Just did furmax burn in test with 7870 OCed to 1150/5000 with intel burn test running at same time and no problems. I did notice that when furmax is running I get lower GFlops on intel burn test. This PSU seems to be doing okay.

For now. "cue evil laugh"

GPUs steal some power from the CPU when they're processing data, hence the loss of CPU grunt.

Took back the OCZ PSU and got a Corsair TX750 Enthusiast series v2. Very happy with this PSU.

I'd had one of those, brilliant little thing.
