Yes, of course!

Hello Dave I would rather go for an 850W power supply, since only the 3080 needs a 750W power supply. LG Flo

In my case, it was only delivered with a German plug last week.

this should work without any problems. the "M" stands for modular, which means you can only plug in the connections you need in the power supply. with this power supply, you have fixed connections that cannot be removed and are either needed or not.

...no, required power supply unit power min. 600W !!!

2x Yes.

Please refer to the GTC under 7.1: Digitec Galaxus or the retailer shall guarantee that the ordered product is free of defects and functional for a period of 2 years after delivery or store collection. .... etc.

Normally it does. If this is not the case, please contact the customer service so that they can send you an appropriate cable.
