The Antec CSK1000 PRO ATX3.1 is more than a power supply. It’s the electrical backbone of your high-performance PC, engineered with precision to support next-generation systems with unwavering reliability and operational efficiency. Drawing from Antec’s legacy of innovation, trusted by builders and gamers alike, the Antec CSK1000 PRO is designed to handle the demands of modern computing environments with intelligence, versatility, and confidence.

At its core lies a 1000W continuous power output, certified under 80 PLUS® Bronze standards to deliver up to 90% efficiency under typical loads. This translates into reduced energy consumption, lower thermal output, and ultimately, a more stable platform for your most intensive tasks—whether you’re rendering large-scale assets, deep into a gaming session, or running demanding productivity suites.

The CSK1000 PRO is fully ATX 3.1 certified, meeting the latest Intel power delivery specifications. It also introduces support for PCIe 5.1, with a dedicated 12V-2×6 connector (capable of delivering up to 600W) designed to power the newest generation of graphics cards, including the NVIDIA® GeForce RTX™ 40 Series. This forward-compatible approach makes it an ideal choice for users building today with tomorrow in mind.

The semi-modular layout gives you the flexibility to customise cable routing based on your build, improving airflow and minimising clutter. Pre-attached essential cables reduce setup time, while detachable connectors provide additional configuration freedom. The result is a cleaner, more breathable system interior, particularly valuable for airflow-optimised cases and minimalist builds.

Engineered for silence as much as performance, the Antec CSK1000 PRO features a 120mm silent fan governed by Antec’s proprietary Thermal Manager system. This intelligent fan control algorithm adjusts speed in real-time based on system load and temperature, delivering the cooling you need without excessive noise, perfect for both high-performance gaming environments and creative workstations where acoustic balance is key.

Underpinning it all is CircuitShield™, Antec’s comprehensive suite of industrial-grade protections. From Over Voltage Protection (OVP) and Over Temperature Protection (OTP) to Short Circuit and Surge Protection (SCP and SIP), the Antec CSK1000 PRO actively defends both itself and your system components against irregularities and power anomalies.

Compact in size yet robust in output, the 140mm chassis ensures compatibility with a wide range of enclosures, giving builders the freedom to design without compromise. Every detail—from the clean cable layout to the reinforced components—is a reflection of Antec’s commitment to quality, dependability, and purposeful engineering.

For those seeking a PSU that matches technical excellence with system-level harmony, the Antec CSK1000 PRO ATX3.1 is a power solution you can build around, with assurance.

I had an issue with my laptop and Anton was very professional and helpful. He offered after hours delivery for my laptop at no extra charge and was able to diagnose the problem and gave a solution all in less than a day. I’ll definitely recommend their services.

I serviced my laptop with CompuMaster that was working like a glorified typewriter with flat keys. Anton collected it at my house late afternoon and I had it the next day midday. Anton kept me informed throughout the process. The work was cost effective, the service was top- tier! If I had not shamed his hand, I’d be convinced he is AI! Service like this just doesn’t exist anymore… Do yourself a favour, call him for all your device needs - he’ll sort you out faster than you can say AI! Keep up the stellar work!!!!👏🏾👏🏾👏🏾

Anton really went above& beyond from the moment we first spoke to assist in sorting out an initial beep(Bios error) on my laptop. Ended up being a much more difficult job in total but he sorted it all. The laptop is running smoothly again - I will definitely use him again and recommend him

I needed ink for my printer and most suppliers around Centurion were out of stock. Anton was relentless in his search and went the extra mile to source the ink from Joburg when others couldn’t help. His persistence and willingness to assist were greatly appreciated. He was also quick to respond to both calls and online messages, which made the whole process easy and reassuring. The company was a little slow with the invoicing, but that’s understandable — Anton is clearly more of a hands-on tech person than an admin person! Overall, great service and a big thank you for your help. Highly recommended.

The service was extremely awesome and Anton who happened to be the one fixing my laptop went above and beyond to help me fix my laptop, charged me less than I was supposed to pay if I’m being honest, he even fixed things he honestly didn’t have to which is heart warming and made me feel extremely comfortable. Honestly the best service I’ve had with laptops by far
