Yes, it is. In my opinion, however, the RTX 2060 for 300 CHF is not a good choice (price-performance-wise), just for information.

Wow.

You are too late, they were available today at 1pm

Probably because someone else was quicker than you and bought it before you completed your purchase. Items in your shopping-cart are not reserved and can be purchased by someone else. Remember, these are times of crazy demand for GPUs.

TDP: 160 Watt Recommended power supply performance: min. 550 Watt

This is due to the demand for GPUs, since the entire RTX30xx series is out of stock and the RX60xx XT series is out of stock, many people are also reaching for "older" GPUs, which is why the price is shooting up again.
