So choices are:

SEASONIC 750W:

SEASONIC 850W:

oh and here is gtx580 sli power draw figures

http://www.overclock.net/power-suppl...sli-power.html

why pay more


exactly the same guts as the seasonic x-850 but corsair gives a 7 year warranty as opposed to seasonics 5 years

As that post shows he is pulling 711 watts from the wall. Factor in efficiency and it's a good bit less then that. Also you will rarely ever get to that much unless you are trying to by running Furmark and Linpack at the same time. 750 watt is perfect for two 580s. Either the AX750 or the X-750 will work. They both are amazing power supplies. I would just go with whichever is cheaper.

Just don't forget who linked the X-750 Seasonic first

I love my 650 and is more than overkill for my single 580. Everything I've seen a 750 will make do for SLI. I wouldn't think there would be much OC room though. Usually bumping voltages on the CPU will start really eating extra wattage up. The previous post showing 711 max draw at the wall is also synthetic just like he said, but if you like running benchmarks over clocked it might get a little hot on the PSU. The seasonic though can probably handle a fair bit over its stated load without fault.

That's 711 watt FROM THE WALL. With power supplies and their efficiency you are pulling less then that from the the power supply... You have no need for an 850 watt power supply whatsoever

Anything between 650-750W will be more then enough for a single 580. Avoid Ultra the only thing ultra about them is how horrible of a unit they produced.

I read that it was from the wall and even put that in my post from the wall. I understand what your saying, but OCing adds some extra wattage. On top of that, maybe the OP decides to upgrade to two 590s, or 680s down the road. That Seasonic PSU is going to be good for many YEARS and I always believe it's best that if affordable, to buy a little more than you need in case you get deep pockets and want more. Saves you from a future upgrade later. That's just from my personal experience, but ultimately is the OPs decision.

Anyway, my vote is the X-750 Seasonic. If you had some time to wait a bit, the X-850 goes down under 200 sometimes like around 189 I think I've seen it for. The corsair 850 unit is no slouch either though. Can't go wrong with Seasonic or corsair considering they are essentially the same units with logos swapped. I believe the particular AX850 you speak of is the logo swap version of the seasonic X-850 so save yourself some bucks if you really want the 850. Seasonic has just never done me wrong so I buy those. Corsair has burned me on RAM before so I'm not a diehard fan of them like I was.

Yeah I've read a lot of bad reviews on corsairs customer service and I've heard they have really good products but If the customer service sucks they don't deserve money. For now I'm looking to to buy the corsair 850 but if the seasonic goes down I'll go with them all the way. Anyways once again thanks guys , you guys helped me a lot and game me a lot more knowledge on power supplies... This is why I joined the forums so I can learn more.
