Is this PSU enough?

[Erstikos]

I'll buy this PC build in few days:
CPU: I5-6600k
MOBO: MSI Z170A Gaming PRO Carbon
GPU: MSI R9 390
Case: Silentium PC Gladius M45W + 2 fans on top
Cooler: Silentium PC Fortis 3 HE1425
RAM: 2x 8Gb HyperX Savage 2400MhZ
HDD: WD Blue 1Tb
SSD: Transcend 128Gb
+ DVD Burer

So, my question is: Is be Quiet! Power Zone 650W enough for this build?

That depends on what you're going to fill all of those expansion slots of that big ATX motherboard with.

650W has about 200W spare capacity so it should suffice for most things, but a second 390 will need a bigger PSU.

As per Endless.It will be fine at this stage, but if you're goping crossfire or adding other accessories I'd consider going up a size.

That should be plenty fine and should give you some overclock headroom for both gpu/cpu.

theres a handy calculator from cm that can be used to estimate power usage:

Unless they've massively improved, I'd highly recommend NOT using calculators since they seem to be wildly inaccurate. Instead, check reviews which measure real power usage.

Coolermaster use the eXtreme Outervision calculator, http://outervision.com/power-supply-calculator and that's by far the most accurate and frequently updated of them ime.

A quick run through the Be Quiet! PSU calculator with my 2 configurations shows that it's simplistic, inconsistent and inaccurate.

Use my rig as your first calculation then switch to an i3 3220 and an R9 270.

Socket 1155 does not support the E3-1230 v3. Why does the latter calculation get flagged for connectors (my 970 has 1x 8-pin, my 270 uses 1x 6-pin)? No consideration given for optical drives (or lack of), USB powered devices, fan controllers...
