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.

Lightweight and True to Size — Best for Casual Use
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
It is nice to see the Amazon Essentials brand expand from household essentials to apparel and shoes. I ordered the Amazon Essentials Men's Lightweight Knit Running Sneakers. The product is made in Vietnam and comes in a shoe box, which is nice. I've noticed that quite often, inexpensive shoes are delivered just in a plastic bag. The sneakers are ready to use and have no odors from glue, organic solvents, etc., which is common nowadays. I wear a size 9W or 9.5. These sneakers are 9.5 and feel like a typical 9.5 size, without surprises. The product is advertised as lightweight, and it is true. Each shoe weighs below 0.6 lb (265 grams). Inside is soft memory foam; the shoes sit on the foot well, snug enough and comfortable, and are easy to put on and take off. They seem like a good fit for spring and summer as casual footwear or for light gym use. The sole is simple and not designed for performance or high-impact activities. Overall, a solid, reasonably priced, comfortable everyday option, though not intended for serious running or training.

Budget buy while being as comfy and stylish as an expensive brand!
Size: 9.5, Color: Navy, Size: 9.5, Color: Navy
My 14 year old had been running his own business since he was 12. He does lawn care and snow removal. His go to shoes when it's too hot for his work boots has always been off brand hey d*de style ones which are terrible for that kind of work as they just don't have the ankle support. He's also had some Orthopedic arch supports custom made for him through the DR in the last year that he needs to use in whatever shoes he's wearing at the time. So I've been on the search for a simple pair of slip on shoes that he could wear while working long hours around our community. He's sent me this picture tonight before heading out. He said "I didn't feel like putting my arch supports in and these are so comfy that I don't even notice I don't have them!" They are sharp looking shoes that really stand out as of they were A high end pair! It's great that they can be an every day style or could be more of a sport shoe as they have the support and padding for both options. In our case they likely be green with in a day or two and it'll be interesting to see how well they wipe off between his work days. I can update this review once he's worn them a bit more. For now they have been perfect for versatility, size was true to size (I did order 1/2 size up, but only did that because he's growing so fast!) and they are definitely a great fit to a budget!!!!

Good purchase.
Size: Medium, Color: Black, Size: Medium, Color: Black
My daughter needed some black sweaters for work at Starbucks. Came across these and snatched one. Price was really good, it is soft, black color is vivid and did not fade after washing. Durable and well-made. Fits as expected...she wanted something loose on her to wear on cold nights over her shirt. Keeps her warm. It came pretty quickly. The material is soft and its comfortable to wear. Nice basic sweatshirt to have in your closet! Pleased with purchase 😊 hopefully this helps!! Oh we intentionally bought bigger for an oversized fit.
