So my build will be finished soon and I'm wondering if a 1000w psu can supply enough power for it???
these are the parts:
Motherboard: MSI X99A Godlike Gaming Carbon Intel X99 LGA 2011 DDR4 USB 3.1 Extended ATX Motherboard
Graphics Card: Gigabyte GeForce GTX 980 Ti XTREME Gaming 6GB GDDR5 Graphics Cards (2-Way-SLI Setup)
SSD: Samsung 850 Pro 2TB 2.5-Inch SATA III Internal SSD (2x)
HDD: Western Digital Black 2TB Performance Desktop Hard Disk Drive - 7200 RPM SATA 6 Gb/s 64MB Cache (2x)
RAM: Corsair DOMINATOR Platinum Series 32GB (4 x 8GB) DDR4 DRAM 3333MHz C16 Memory Kit
CPU Cooler: EKWB EK-XLC Predator 360 All-In-One CPU Liquid Cooling Unit
Processor: Intel Core i7-5960X Processor Extreme Edition
Case Fans: EKWB EK-Vardar F3-240 High Static Pressure 140mm Cooling Fan

THANKS IN ADVANCE!
 
Solution
1000W would really be overkill. You're better off going with a higher quality 850W (e.g. EVGA 850 P2) and maybe getting a sleeved cable kit.

By the way, have you already bought the parts?
it not the total wattage of a power supply you have to look out with a gaming rig it the max amp on the 12v rail and how close to the rail max you are. you dont want to load a power supply to 80-90 percent of the 12v rail it run hot and loud during gaming and may ripple out or not hold. oversizing a unit will also help when the caps age.

yes, I have bought all the parts, the final step is just to build it!

 


All PSUs of any respectable quality are rated based on the wattage of the 12V rail and are fully capable of running just fine even at 100% constant load. Lower-end quality units may not hold up for long under such load, but units like EVGA G2s and Corsair RMx/RMi series can run with that load just fine within their expected lifespan.

If you're buying quality units capacitor aging is also not an issue since at 60-70% load its lifespan will be way beyond what you need.

Maximum power ~ 740 W. Recommend quality PSU rated at a minimum of 900 W.

A few suggested quality PSU's -

Antec HCG-900

EVGA SuperNOVA 1000 G1

EVGA SuperNOVA 1000 G2

Protip: don't base power requirements off either calculators or what the manufacturer says the card consumes. You can run a single 980 Ti with a consumer CPU comfortably with even 500-550W PSUs (assuming they're not junk), a couple of 980 Tis with an i7 Extreme won't require more than an 850W unit.
