Yes it is ok, but usually i prefer Corsair RM or RMx, Seasonic Focus Gold, Bitfenix Wispher, and Cougar GX-F (good brand, cheaper price since it's OEM Brand from HEC iirc), all of them from the range from 650w to 750w, just pick which one suits you best for the price. Your country voltage should be +-10% 240v @50hz, so if you could see the psu label 80+ somthing 230v EU, you should be ok to pick them.
Also, after you install the PSU, use 1 PCIe power cable per slot on the gpu, do not daisy chain them as there is some problems if you do daisy chain the psu, so use separate cable per pcie power slot (yours 2x8pin, so do 1 cable per 8 pin each from the psu), it should be like this:
