What power supply should I get?

[Marioraider18]

This is going to be my pc setup. I dont think I will ever do SLI but maybe Overclocking

CPU: Intel Core i7-5820K 3.3GHz 6-Core Processor ($378.99 @ SuperBiiz)
CPU Cooler: Cooler Master Hyper 212 EVO 82.9 CFM Sleeve Bearing CPU Cooler ($26.98 @ OutletPC)
Motherboard: MSI X99S SLI Plus ATX LGA2011-3 Motherboard ($199.99 @ SuperBiiz)
Memory: Kingston HyperX Fury Black 16GB (4 x 4GB) DDR4-2666 Memory ($164.99 @ Newegg)
Storage: Samsung 850 EVO-Series 250GB 2.5" Solid State Drive ($97.95 @ OutletPC)
Storage: Western Digital Caviar Blue 1TB 3.5" 7200RPM Internal Hard Drive ($52.49 @ OutletPC)
Video Card: EVGA GeForce GTX 980 Ti 6GB ACX 2.0+ Video Card ($649.99 @ Amazon)
Case: Phanteks Enthoo Pro ATX Full Tower Case ($99.99 @ Amazon)
Power Supply: EVGA 1050W 80+ Gold Certified Fully-Modular ATX Power Supply ($134.99 @ NCIX US)

Does it matter what type of power supply I get? Is watt the only indication of what type of power supply I should buy? Is the power supply above overkill?

Yes it is overkill for a single GTX 980Ti build. You could get the EVGA GS650W instead if you not gonna add another GTX 980Ti.

Overkill.... Nvidia GPUs are generally efficient.
EVGA SuperNova G2 750w gold modular for u...

Total overkill since no SLI in the plans, this EVGA G2 unit one off the best http://pcpartpicker.com/part/evga-power-supply-220g20650y1

"Does it matter what type of power supply I get?"
Yes it matters. Types are ATX, SXF, TFX etc...different sizes for large or small cases.

"Is watt the only indication of what type of power supply I should buy?"
No. Continuous available 12volt amperage is the key factor.

"Is the power supply above overkill?"
Yes. You don't need that much power for a single GPU. 650 watts from a high quality PSU is fine.
