Hi im looking for a PSU for my gaming system

My system specs are

Intel i5 2500k 3.30 @ 4.6 oc
Asus P8Z68-V
Corsair 8gb Vengeance ram 1600
Corsair H60 Liquid Cooler
Corsair Force 3 120 gb SSD
500GB SATA-III 6Gb/s Barracuda Hard Drive
Nvidia KFA2 560Ti extreme overclock edition
Iyama Prolite 24" 1080p monitor

i have a crappy artic 600 watt full Mod psu that i bought like 8 years ago and ive been meaning to upgrade the psu for a while but never got round to it. It still works absolutely fine but every other part of my pc is brand new and i think it deserves a new psu to go with it :P

I plan on buying another 560ti at the same time when i have chosen my PSU
so it has to be able to handle 2 of these cards

i was thinking a 750watt psu would be plenty , but i cant decide which one to go for. I really like corsair though

so any suggestions , i use pc mainly for gaming , i see the gaming corsair psu i think its called corsair GS800 but it isnt modula but i like the look of it would it have all the cables i need to power all of the above that i have mentioned?

Running SLI/XFire through a single 24" monitor is a complete waste of money :eek:

If he decides/can afford to go multi monitor and SLI/XFire he can upgrade the PSU then as well :)

i will be going 3 monitors eventually , but can i ask why it would be a waste of time? im not dissagreeing i would just like to know why so i dont make a mistake
 
Basically, you'll be investing x amount of pounds in a GPU just to sit in your system for bragging rights alone.

The sheer horsepower in a middle to top end single GPU is more than enough for a single monitor. Indeed some of them will quite happily power 2+ ( of course with Nvidia you'll need 2 for 3 monitors = time to switch to a single AMD :) )

I made the same mistake with the older 5870 series. When I had a little look at the actual work load of the 2nd GPU ..... it was just idling. And that was across 3 monitors, Hence I switched to a single GPU.

The idea of getting a "bigger" PSU for "future proofing" is also complete twaddle IMO, Again I made the mistake of getting a top end PSU... waste. It's pulling full wattage from the mains all the time that it's switched on but hardly using half of it.

Stick with a mid range one as suggested.

i bought last night XFX 750W XXX Edition Modular '80 Plus Silver' Power Supply

and a second 560 ti http://www.******.com/284529-kfa2-gtx-560ti-ex-oc-edition-1gb-gddr5-dual-dvi-mini-hdmi-56ngh6hs4itz

i do plan on buying 2 more monitors of same model with my next pay check

i was debating the idea of just buying a 580 and selling my 560ti but ive done some research and 2x 560ti aparentely completely outperforms a single 580.

i went with the xfx psu over the corsair ones due to the fact that xfx are rebranded sea sonic power supplies and they aparently are very good psu's (from what ive read)

Er, that's twaddle.

The PSU will only draw the amount of power it requires from the mains to power the components it's connected to.

Assuming equal efficiency then a 1250W PSU only uses the same amount of electricity as a 750W PSU when connected to the same components.
