In the world of data centers, discussions about energy efficiency are often dominated by one topic: cooling. Manufacturers compete to develop increasingly efficient cooling systems. And yes, that matters. But in the race to lower temperatures, it is easy to overlook the second equally fundamental pillar – one without which everything else becomes irrelevant: power supply.
Our experts often emphasize that power supply and cooling are the two essential elements without which a data center simply cannot operate. They are like the heart and lungs of a living organism – the failure of one immediately affects the other and the entire system. However, when viewed through the lens of business priorities, power supply takes the lead. Why?
Power Supply – the Foundation of Business Continuity
Let us imagine a data center as a fortress protecting your company’s most valuable assets: its data and systems. Cooling is like the walls and moat – it protects against overheating, which is a very real threat. But power supply is the foundation and the only road leading to the fortress. If the foundation collapses, the entire structure – even with the strongest walls – becomes useless.
The same is true of power. Even the most advanced, perfectly cooled servers are nothing more than a pile of expensive, useless hardware without electricity. A power failure is not just a technical issue. It means the immediate paralysis of critical business processes, the risk of data loss, halted transactions, and very real financial consequences.

Efficiency vs. Reliability – Where Is the Balance?
Our experts also point to an important distinction. From an energy-efficiency perspective, cooling offers greater potential for savings. It is responsible for a significant share of total energy consumption, and optimizing cooling systems can substantially reduce electricity costs. Power systems, while they also consume energy, tend to generate smaller losses – modern UPS units can achieve efficiency levels of 95–98%.
However, when business continuity becomes the priority, the order changes. A temporary fluctuation in temperature inside a server room may not necessarily have catastrophic consequences. Even the briefest interruption in power supply, on the other hand, can lead to equipment damage and data loss. That is why it makes little sense to ask which system matters more. Both are critical, and both must operate in perfect synergy.
How Does Talex Approach Power Supply?
We understand that what matters most to our clients is peace of mind – the confidence that their systems will run continuously, 24/7/365. That is why at Talex Data Center we take a no-compromise approach to power supply. Our infrastructure is built on two fully independent power paths. From separate utility connections, to distinct switchboards, dedicated UPS rooms, and two power distribution units in every rack – redundancy is designed into every layer.
We invest in equipment from leading manufacturers, with efficiency reaching up to 98%. This is not only a guarantee of reliability, but also a source of tangible savings. We regularly test emergency scenarios to ensure that, when a critical moment comes, every part of the system performs exactly as planned.
Cooling matters. Energy efficiency is essential. But everything begins and ends with stable, uninterrupted power supply. It is the foundation on which we build the security and business continuity of our clients’ operations.
