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-2x6 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.

Significant Improvement in Performance with Liqui Moly Jectron
Size: 300 Milliliter
I've been using the Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner in my vehicle, and I am thoroughly impressed with the results. The 300 ml bottle, though compact, has made a noticeable difference in the performance of my car. After adding the Jectron cleaner to my gasoline tank, I noticed an improvement in the engine's responsiveness and smoothness within just a few drives. The idling has become steadier, and the acceleration feels more robust and refined. It's as if my car has regained a level of vitality that I hadn't realized was missing. The cleaner is incredibly easy to use – simply pouring it into the fuel tank before filling up ensures it mixes well and distributes evenly throughout the fuel system. I appreciate that this product is designed to be compatible with all gasoline engines, making it a versatile choice for different types of vehicles. One of the most significant benefits I've observed is the reduction in start-up problems and engine hesitation. It's clear that the Jectron cleaner effectively cleans the fuel injectors, improving fuel atomization and combustion efficiency. This has not only enhanced the driving experience but also contributed to better fuel economy, which is a fantastic bonus given current fuel prices. The blue color of the liquid and the design of the bottle make it easy to identify and use, ensuring I don't mix it up with other products. Despite being a single 10.14 Fl Oz pack, this cleaner packs a punch, proving that a little goes a long way. In conclusion, the Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner has exceeded my expectations. It has revitalized my car's engine, improved fuel efficiency, and provided a smoother, more enjoyable driving experience. I highly recommend this product to anyone looking to enhance their vehicle's performance and maintain the health of their fuel injection system.

Reputable, reasonably priced fuel additive to clean valves, with handy dispenser. Not all comes out.
Size: 300 Milliliter, Size: 300 Milliliter
Honest review of Liqui Moly 2007 Jectron Gasoline Fuel Injection Cleaner - 300 ml , blue @ $8.68 at time of order. I recently acquired a 2002 Ford Taurus with the 3.0L V6 and DOHC. It only had about 131,000 miles on it, but I noticed it seemed like there would be some intermittent misses in the firing. Other than oil changes, I do not believe that this vehicle was mechanically well maintained. After some research and reading reviews of products, I opted to try some injection cleaner as one step in a treatment regimen. I will endeavor to update this review with results after giving it time to work. Likes: Amazon Prime shipping, returns and refunds within 30 days of receipt. Reputable product. The price point seemed reasonable, especially if it works as advertised (10.1 ounces, single treatment can). Comes with dispensing attachment for easier pouring. Dislikes: The design of the can and pouring mechanism left a small amount of product inside the can of valve cleaner. Even completely inverting the can it wouldn’t come out. Granted, it wasn’t a whole lot, but I paid for all of it, not for some left in the can that wouldn’t even shake out. Sorry if this sounds nitpicky, but it is also a problem for disposal afterwards as it has to sit out and evaporate or put it in the trash with flammable liquid inside. Meh: I have put several miles on since adding this to just over a quarter tank of fuel and have not noticed any improvements. I realize it might take a while longer perhaps. Hopefully this honest review helps someone decide about this product.
