New build with Titan X

[Zilent]

So, this is the updated build list for my 4x GPU system (all cards inside closed chassis):

1 x LEPA MaxPlatinum 1700 (P1700-MA-EU)
4 x MSI NTITAN X 12GD5 - GF GTX TITAN X 12 GB
1 x Gigabyte GA-Z87X-OC Force
1 x Intel Core i7 4790K / 4 GHz
4 x Kingston HyperX Savage DDR3 8 GB 2400 MHz
1 x Samsung 850 EVO MZ-75E500 - SSD 500 GB - SATA 6Gb/s
1 x Chenbro 19 4HE RM41300G EEB (RM41300-FS81)

Regarding the Power Supply. One could probably go with the 1600W (1700W peak) version:

So I haven't decided on that, but the price difference is minor.

Obviously, if I lived in a country, where the z97 version of the MB (like GA-Z97X-Gaming G1 rev. 1.0) was cheaper, I'd go for that, but here it's a lot more expensive actually (double up).

Any last concerns to address?
