Hi I need a psu for my build thats modular and Can Support 2 Graphics Cards
My build Consists of
i7 4790
Asrock Z97 extreme 4
Nzxt h440
6 120mm fans and 1 140mm fan
gtx 750 ti(physx)
Gtx 780 ti(Main)
16 gb g. skills trident x 2400 mhz cl10

Also i plan on buying a ASUS PB278Q LED monitor 27" 60hz 1440p monitor
i saw on tweak town that you can overclock the 60 hz to 85 hz.
Will this void the warranty and does it damage ir or decrease lifespan.
plus will i notice a large difference in games. i dont often play games such as battle field for or CS:GO.

I would spend $10 more and get this psu for the single +12v rail rather than the antec with dual +12v rails

do not get corsair AF fans , get bitfenix spectre pro fans , i will explain why
Bitfenix spectre pro 120mm fan - CFM 56.22 noise 18.9dba
corsair AF 120mm CFM 52.19 noise 25.2dba
Both - same price bitfenix pushes more cfm and is quieter for the same price
bitfenix spectre pro 140mm fan CFM 86.73 noise 22.8dba
corsair AF 140mm CFM 66.4 noise 25.5dba
big difference on the 140mm with CFM

Hi Samuel Lawrence
A single 780ti requires 42A on the +12v rail and a 600W PSU minimum
for your 2 780ti's you will need a minimum 950 watts
For the price this is a great option , this is larger than you need , will give you heaps of headroom and 108A on the +12v rail
and is fully modular and has a ten year warranty and has high grade japanese capacitors ,
this is overkill but 1050 watt seasonic is $295 and has 87A on the +12v rail , for an extra $40 you get the higher wattage ,amperage and ten year warranty

I was assuming he meant 2 cards total, including the physx card, but I could have been wrong.

Heres what i was thinking for a 780 ti and 750 ti. Its modular rater as a tier two psu an will do me good. If i plan on sli( which i probaly wont id probaly upgrade to 800 series which will be lower power consumption) ill buy a better rater one but for 1440p it seems 1 780 ti will work for 2-3 years and buy then i would of upgraded
Do you guys think this will work
the only cable that isnt modular is the atx power connector
