Which PSU to pick?

[saelondo]

Looking for a new PSU and got a little bit confused.
Recently I bought Cougar GX-S650, which looked like an awesome choice for its price (Tier 3 in the PSU Tier List) - but it died after 2 days (around 20 working hours). A faulty unit most likely, but quite a stressful experience.

So, the PSUs I’m considering for the replacement are (the budget is around 100$, the region is CIS, Kazakhstan):

Seasonic SS-600ES, 600W
Seasonic S12 II, 620W
BeQuiet, System Power 9, 600W
BeQuiet, Pure Power 10, 600W

My specs:

Motherboard: ASUS H97M-PLUS
CPU: Intel Core i7-4770
RAM: 16,0Gb Dual-Channel DDR3 at 665MHz
GPU: 4095MB NVIDIA GeForce GTX 970 Strix (ASUS) [no overclocking, but I may use MSI Afterburner to speed up the fans a little bit]
HDD: 1863Gb Seagate ST2000DM 001-1ER164 SCSI (SATA) [with possible connection of the second one of the same grade]
Monitor: DELL P2012H, LED, 20'' (1600x900 resolution)
Optical drive: Optiarc DVD RW AD-7260S SCSI
[PSU (current, the one I'm going to replace): HuntKey APFC 700W]
UPS: SVC V-1200-F (1200VA / 750W)
Other: Wi-Fi router, Xbox wireless controller; standard USB mouse and keyboard; sometimes I connect a hi-res TV screen with a HDMI cable

Will 600W really suffice (OuterVision PSU Calculator (on Expert Mode) gives me around 500W of recommended PSU Wattage)? Which one would you recommend (not necessary from the above-mentioned four)?

Thank you for the answers!

Anything 450 watts or over from a quality OEM is sufficient for your build. From those listed, I'd choose either the Seasonic S12II or the Pure Power 10.

The Pure Power 10 is more up to date than the Season S12II, however the Season S12II is more reliable.

Here a Tom's Hardware review from the BeQuiet! Pure Power 10:
