- The campaign runs from May 4 to May 18, 2026 (“Campaign”).
- The list of products currently available in the Campaign (“Products”) can be found on this website below.
- A Product is considered purchased at a discounted price as part of the Campaign only once the order has been confirmed by Alza and the payment has been completed by the customer. Simply placing the Product in the cart does not constitute a purchase. If the Buyer selects cash-on-delivery payment, submitting the order to Alza within the Campaign period is sufficient, but the discount will only be valid upon successful payment upon delivery.
- Alza reserves the right to limit the number of Products a single buyer may purchase during the Campaign for certain items. Should such purchase limits apply, Alza's system will automatically prevent buyers from adding more Products to their cart than the permitted purchase quantity for the duration of the Campaign.
- Available stock of select Products will be allocated among consumers in the Czech Republic, Slovakia, Austria, Hungary, and other countries served by Alza.
- Discounts on Products are valid only during the Campaign period or while supplies last. Alza reserves the right to change the selection of discounted Products at any time during the Campaign.

Alza Days - PC Power Supplies
Computer power supplies are standardized according to the ATX format, created in 1995 by Intel as a standard arrangement of components in computer cases. At that time, it replaced the older standard AT format. In 2003, Intel tried to replace it with BTX, but manufacturers did not switch to that format and instead ATX was revised several times. The latest and current versions are ATX2.2, and smaller formats mATX and Mini ITX.
As the ATX format developed, there were also changes in power supply - ie, in the area of computer resources. Therefore, it is now using ATX power supply for computer assembly versions 2.0, 2.2, 2.3 and 2.4 which differ in the main power connector, which plugs into the motherboard. It is therefore necessary for you to match the selected source to a version compatible with the motherboard.
When deciding which power source to buy, it is important to know the overall performance specification (given in watts and must be sufficient for the computer system - eg. For desktop computers 350-400 W is sufficient), cooling type and the amount and variation of additional power connectors.
