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.

The Best for Athletics
Color: Black/Gray
This is a sleek, light wristwatch that will not weigh you down with its bulk. Forget the gigantic profile of a "survivalist" wristwatch. This unisex model is svelte and slim, not adding much to the wake you generate while swimming, or the swing of your arms while running, or the wind as it passes around your wrists and hands while you are speeding by on your racing bike. This is only 34mm across, by 35mm tall, by 11.5mm thick. The wristband is 13mm at its median working width. Timex styling cannot be beat, and neither is the resin-rubber-like material. I don't know about you, but the price is something I take a good look at. I want a watch that is reasonably priced and high-quality. I don't want to spend $200 to $1000 on a watch and worrying about being careful with it. If it gets smashed, it's only $30 to $50, not a big loss, and the quality is way better than what they were making in the 1980's. These watches are made for athletics and the real world.

Great watch, flimsy band
Color: Gray/Lilac
I bought this watch to replace a similar model because the band broke. I see this is a recurrent problem in many other reviews. However, I liked the watch enough to buy it again anyway. I found the new model easy to set, being fairly intuitive. So far it keeps perfect time. I use this watch mainly as a travel watch, and loved the dual time zone function. I am pleased that the newer model now has the ability to set 3 times zones instead of 2, which is an added bonus. The only con I see at this point is the flimsy strap. Unfortunately, the strap on this model is even thinner than on the previous one, and I wonder how long it will last. Also I wonder about the battery length. I think these watches may have been sitting around a long time. The setting showed 2012. I am afraid much of the battery life of the original battery may have already been used up and the battery may need replacing early. Only time will tell. The watch fits my small wrist fine and it is a little more attractive than the old model. I give it 4 stars instead of 5 only because of the band problem.

Fine for a man (with skinny wrists)
Color: Black/Gray, Color: Black/Gray
I have an older mens ironman which has gotten a little beat up and needs replacing. The band is much longer than I need. The metal clasp sits off-center on the underside of my wrist, closer to the part of my wrist which curves around to the front. The too-long strap sometimes flops around and catches on things. I couldn't find a smaller-band mens version, so I tried this "womens" watch (picking the most manly-looking one, of course). I like it better. The band fits my wrist much better, with the metal band in the middle and no flop. I also like that the watch is lighter and the face and band are smaller and less bulky, so it is less noticeable when I'm wearing it (cycling weight weenies will appreciate this). The face is still large enough to be easily legible and contains all of the same great features as my mens ironman watch, plus the newer versions now have an hourly chime, nice! Other info: my wrist is ~17.5cm or ~7.0" around. On this watch, I use the 6th out of 9 slots on the band. On my mens ironman, I use the 3rd out of 9 slots. Weight: this one = 28g, mens = 39g. Pics show comparison of my prior mens ironman with this new "womens" ironman. Photo order is confusing (couldn't figure out how to change that). They are: (1) side-by-side, mens on left, (2) mens band (wider and clasp is off-center on my wrist, end of band hangs over the edge of my wrist -- too long for me -- catches on things), (3) womens band (less wide, clasp is more centered on my wrist and end does hang over edge of my wrist), (3) womens watch (smaller, and looks new), and (5) mens watch, looking a little beat up.

Watch holds up in saltwater!
Color: Black/Gray
I bought this watch to use for my trip to the Galapagos Islands. I read two reviews that the watch does not hold up in salt water. I went snorkeling in the ocean 6 times, about 45 minutes each time. The watch did not leak. I did take precautions by keeping the watch under my rash guard and lowering myself slowly into the water. I also rinsed off my watch each time I snorkeled. I also bought this watch for the multi time zone feature by saving the time on the west coast, east coast and Galapagos time since I cannot change the time on my Fitbit until I land in an airport. I did not use any other features of the watch because I generally use my phone or Fitbit for an alarm or timer. The only complaint I have is that Timex now discourages changing the battery by the consumer. I changed the battery myself on my old Ironman watch. The new Ironman watch is fitted with triangular head screws. So I will have to purchase screwdrivers with triangular heads when it comes time to change the battery.
