Right,

Asking us to spec a PSU without giving us a PC spec is pointless. We need details of the machine you're running it on.

Straight away rule out anything over 850w. 1000w is silly for anything other than triple 580's. it wouldn't surprise me if triple 680s can be run on an 850w PSU, your 7970's pull around 250w each.

I'd go with the seasonic x750 gold myself. $150 I think they are over in the states. I wouldn't pick anything you've put up the top here.

We need to know cpu and gpus at a minimum, and your overclocking intentions. Ideally we need ram, hdds/ssds, fans, other peripherals as well.

Search on here for psucalc, its a great tool made by OCN members.

Oh well. Here it goes:
3930k overclock as high as possible (5.0 with 1.5 volts is 317 watts)
Water2.0 Extreme
EVGA x79 FTW
Radeon HD 8970 when released and overclocked to the pants
Patriot Memory Viper 3 Series Venom Red DDR3 16GB 1600MHz
CM MegaFlow RED 200mm
CM Red LED FAN 4x, 2 case and two to replace the fans on the 2.0
CM Storm Stryker
Barracuda 1TB 7200RPM
Plantronics 780
Yamaha NS-SP1800BL

I want this PSU to last, and I know that the PSU gives less amps over time, and umm... Will want to crossfire as much of 8970's as possible. Not more than 3.

That's more reasonable smile.gif

You can still do a xfire setup on a 650w PSU of the 7970's, if you're doing tri-fire then i'd personally go with an 850w psu just for a little peace of mind, but in realistic terms it'll still be more than enough biggrin.gif

Even with your overclocks and your watercooling etc, 650w for xfire is more than enough, those cards will pull around 220w each, so you'll be well within for the rest of the machine. I'd put my money on around the 600w mark all in all.

Just don't go and get 10w fans (scythe ultra kaze 3k RPM)

One thing you seem to be doing is overspec'ing a lot on the machine and giving miles too much wattage. You can run things like xfire 7970's and SLi 680's on a 750w easily.

I had SLi570's on a 650w PSU, original post btw has been edited.

I heard that the PSU will over time provide less power. Is that correct? Because maybe if not, I can get a 100$ PSU and get a 100$ SSD biggrin.gif

that's not entirely true,

If a PSU is being loaded at 85% I think it is the capacitors don't degrade as much since they are being stressed regularly. However, if you take a 1.2kw PSU and throw it in a machine that is utilising 400w, that's an 800w difference so you're running it at what? 25% of load or something? That will cause it to degrade and then over time it won't be able to give the rated load.
