If you're overclocking to 6.5GHz then I suspect you should be more worried about obtaining LN2 or DICE than whether or not your PSU can take an extra 50W...

Sarcasm or no?

Thread Starter 
Ok, well my CPU under DICE at 5Ghz, and with my 5870, and 1 hdd, i maxxed out my old OCZ Zseries 650W PSU. So im thinking a CPU alone can easily pull 400W+ at 6.5+ and have been told this on more than one occasion and thats why im worried about multiple rails, not being able to supply the power. That leaves 800W for GPU's and the rest, of which i want headroom. I have another 5870 i can lend for bench session etc. so...

And once bulldozer is out, im hoping the the ROG boards will have 4 PCI-E slots to run quad crossfire at benching sessions.

So that is why i want the headroom.

Quote:
That said, I cannot see a Corsair PSU being less efficient or of lower quality than an Antec one.
Agreed, they are pretty much on par with each other, but as mentioned, I need 100% modularity. Not even the 24pin ATX connector must be fixed.

Lol, he obviously has not read this thread, and hence the other side of my concern.

I need a high wattage rail for the CPU, but at the same time not too high to do this, AARRRGGGG, why can they make a customizable rail system, so i can have like 8 rails on a day to day basis, and for a OC session, drop it down to liike 2 massive rails, and then just change it back afterwards...

To be honest you won't see much of a difference in real-world testing. We've tried and tried to duplicate real-world scenarios with a real system where you could see the limitations of a single-rail setup (or a modern multi-rail setup) and it just doesn't happen.

If you choose an AX1200 and have any problems, just PM me and I'll take care of it for you.

Single rail psu's aren't dangerous, it's just the consequences are MUCH worse if something does go wrong. chances of a problem don't increase, but the damage from one does.

Exactly. +50 rep and this plastered all over the screens of everyone bugging me about this issue.

edit: single rail psus require more vigilance on the user's part as to not overload it. Take a multi rail and a single rail and overload the *** out of them. The single rail might handle it, but it would be very easy to fry something. The multi rail will shut down from the protection kicking in.

this * does not * mean the single rail handled it better than the multi rail.

The single rail would be struggling just as much.

I'm pretty sure he meant to do that to add to the sarcasm.
