										<content:encoded><![CDATA[<p class="p1">Acer has unveiled its TravelMate X4 14 AI business laptop and two sustainable Vero laser projectors, targeting small and medium businesses (SMBs) and hybrid workforces with AI-enhanced productivity tools and eco-conscious design.</p>
<p class="p1">The announcements at IFA 2025 reflect growing demand for intelligent business solutions that balance performance, mobility, and environmental responsibility.</p>
<p class="p1">The TravelMate X4 14 AI (TMX414-51) is designed specifically for SMBs and mobile professionals requiring robust performance in a portable package.</p>
<p class="p1">Powered by up to Intel Core Ultra 7 Processor 258V delivering 115 TOPS of overall performance, it runs Windows 11 Pro with full Copilot+ PC experiences.</p>
<p class="p1">AI features include Recall (preview), Click to Do, improved Windows search, Cocreator in Microsoft Paint, and Live Captions for real-time multilingual translations.</p>
<p class="p1">These tools aim to enhance productivity and collaboration for distributed teams.</p>
<p class="p1">Weighing just 1.27kg and measuring 15.9mm thin, the laptop doesn&#8217;t sacrifice durability for portability.</p>
<p class="p1">It meets MIL-STD 810H standards, withstanding vibrations, humidity, and extreme temperatures, essential for professionals who travel frequently.</p>
<p class="p1">&#8220;As AI is becoming increasingly important in modern business workflows, small and medium businesses need devices that integrate intelligent tools, robust security, and mobility,&#8221; said James Lin, General Manager, Notebooks, Acer Inc.</p>
<p class="p1">The 14-inch 16:10 WUXGA display provides ample screen space for productivity tasks, with an optional OLED panel offering 500 nits peak brightness and vibrant colours.</p>
<p class="p1">TÜV Rheinland Low Blue Light certification (hardware solution) supports better eye comfort during extended use.</p>
<p class="p1">Acer PurifiedView 2.0 and PurifiedVoice 2.0 technology, paired with DTS:X Ultra Audio-enhanced speakers, ensure crystal-clear video calls, crucial for remote collaboration.</p>

<p class="p1">Both models feature IP6X dust-proof rating and 24/7 operation capability for demanding use cases, plus 15W built-in speakers with dedicated sports modes.</p>
<p class="p1">Reinforcing sustainability commitments, both projectors incorporate 50% post-consumer recycled plastic in their chassis and use 100% recyclable packaging.</p>
<p class="p1">The TravelMate X4 14 AI will be available in Australia (timing TBA) starting at $2,499, competing with business laptops from Lenovo ThinkPad and HP EliteBook series while offering superior AI integration.</p>

<p class="p1">These prices position them competitively against business projectors from Epson and BenQ.</p>
<p class="p1">Microsoft&#8217;s Mark Linton, Vice President of Windows + Devices, noted: &#8220;With powerful performance, enhanced security, and unique AI experiences, it&#8217;s an ideal choice for today&#8217;s professionals looking to upgrade to a PC that prioritises portability and performance.”</p>
<p class="p1">The launches demonstrate Acer&#8217;s commitment to the business sector, offering AI-enhanced productivity tools and sustainable solutions that address the evolving needs of modern workplaces.</p>

										<content:encoded><![CDATA[<p class="p1">Acer has announced the Predator Orion 7000 desktop, a high-performance gaming system designed for enthusiasts, content creators, and professionals demanding uncompromised power and cutting-edge features.</p>
<p class="p1">The desktop represents Acer&#8217;s flagship gaming offering for the Australian market, combining latest-generation processors, graphics, and an innovative cooling solution in a striking chassis design.</p>
<p class="p1">The Predator Orion 7000 (PO7-667) features up to Intel Core Ultra 9 processor 285K with an integrated NPU for AI workloads, ensuring lightning-fast processing for gaming, streaming, and multitasking.</p>
<p class="p1">The processor&#8217;s AI capabilities extend beyond gaming, supporting content creation and productivity applications.</p>
<p class="p1">Paired with up to NVIDIA GeForce RTX 5090 graphics, the system delivers ray-traced visuals and advanced AI capabilities including DLSS 4 with Multi Frame Generation.</p>
<p class="p1">It also provides access to NVIDIA NIM Microservices, state-of-the-art AI models that allow enthusiasts and developers to build AI assistants, agents, and workflows with peak performance on NIM-ready systems.</p>
<p class="p1">Memory and storage specifications match the high-end components, with support for up to 128GB DDR5 7200 MT/s XMP RGB RAM for seamless multitasking and memory-intensive applications.</p>
<p class="p1">Storage options include up to 6TB SSD for blazing-fast load times, plus up to 4TB hard drive capacity with support for two 3.5-inch drives.</p>
<p class="p1">To maintain peak performance during demanding sessions, the Predator Orion 7000 employs the Predator CycloneX 360 cooling system with CPU liquid cooler.</p>
<p class="p1">The advanced thermal solution features a unique fan layout and open channel structure that boosts cooling efficiency by 15% and lowers motherboard temperatures by 9°C.</p>
<p><img decoding="async" class="wp-image-98775 aligncenter" src="https://smartoffice.com.au/wp-content/uploads/2025/09/0125477f-6f4a-4116-b96d-0f598c456734.jpg" alt="" width="624" height="624" /></p>
<p class="p1">This engineering ensures optimal airflow and heat dissipation, allowing components to operate at full potential without thermal throttling.</p>
<p class="p1">The result is consistently stable gameplay even during extended gaming marathons or intensive rendering tasks.</p>
<p class="p1">The system is housed in an EMI-compliant tempered glass chassis with customisable ARGB lighting, allowing users to personalise their setup&#8217;s appearance.</p>
<p class="p1">The 45L chassis incorporates 65% post-consumer recycled plastic in its total plastic content, demonstrating environmental consideration without compromising on style.</p>
<p class="p1">Connectivity options include Killer Ethernet E3100G and Wi-Fi 7 for low-latency online gaming, alongside Thunderbolt 4 for versatile high-speed connectivity with peripherals and external devices.</p>
<p class="p1">The comprehensive I/O ensures compatibility with current and future gaming accessories.</p>
<p class="p1">The desktop also features Acer Intelligence Space, a smart hub of AI applications designed to boost creativity and productivity beyond gaming applications.</p>
<p class="p1">The Predator Orion 7000 will be available in Australia in late Q1 2026 from Harvey Norman, starting at $8,199.</p>
<p class="p1">This pricing positions it against premium gaming systems from competitors like ASUS ROG Strix and MSI MEG series, though the inclusion of RTX 5090 graphics and advanced cooling may justify the premium.</p>
<p class="p1">For Australian gamers and content creators seeking a no-compromise system with the latest technology, the Predator Orion 7000 represents Acer&#8217;s most ambitious gaming desktop to date, combining raw performance with thoughtful design and sustainability considerations.</p>

<p class="p1">Complementing the laptop, Acer introduced two new Nitro monitors offering immersive visuals across different formats and price points.</p>
<p><img decoding="async" class="wp-image-98771 aligncenter" src="https://smartoffice.com.au/wp-content/uploads/2025/09/9c576ecc-f522-4fc0-a68a-545785bf4f31.jpg" alt="" width="1087" height="725" /></p>

										<content:encoded><![CDATA[<p>Six years ago, Acer was struggling, their product mix was wrong, Alienware was the #1 PC gaming brand, then along came new management, followed by a totally new PC range, then came the Predator gaming brand.</p>
<p>Today Acer is a PC gaming powerhouse and at their New York reveal today, the #1 gaming brand rolled out a new generation Predator gaming range with most of their new range set to become the benchmark for gaming enthusiasts.<a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_120551.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95328" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_120551.jpg" alt="" width="1670" height="812" /></a></p>
<p>The highlight of Acer&#8217;s gaming line up is the Predator X desktop, while this is still undergoing some tweaks but whrn it does hit high street stores later this year Acer is confident that it will become the ultimate desktop for hard core gamers.</p>
<p>With its dual Intel Xeon processors more commonly found in top end servers and all powerful CAD and video editing workstations this machine is packed with processor power.</p>
<p>Some say it&#8217;s overkill for a gaming machine but when killing is counted in milliseconds and you need the ultimate video rendering this is the machine that seriously excited hard core gaming writers at Acers New York reveal.<a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_120137-1.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95326" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_120137-1.jpg" alt="" width="1670" height="812" /></a></p>
<p>And for those who want a top end gaming machine but don&#8217;t need dual core Xeon processors Acer has an all-new gaming range built around Intel&#8217;s new Core+ CPUs, which come with Intel Optane memory built in.</p>
<p>At the top end of this category is the Predator Helios 500, a 17.3-inch monster laptop with up to an overclockable Core i9 processor. You can configure this beast with up to 64GB of RAM and either 1TB of SSD storage or a 2TB spinning drive.</p>
<p>There is also an overclockable GeForce GTX 1070 graphics and either a 1080p 144Hz screen or a 4K panel.<a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_114921.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95324" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_114921.jpg" alt="" width="1670" height="812" /></a></p>
<p>Stepping down in size there is the Helios 300 which comes in a new colour white, along with a white bag and matching mouse.</p>
<p>The &#8220;chic&#8221; white-and-gold colour scheme along with a faster 144Hz display is aimed at the style conscious consumer who wants a great looking machine that has a lot of grunt under the bonnet said one Acer executive.<a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_114819.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95321" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_114819.jpg" alt="" width="1670" height="812" /></a></p>
<p>It&#8217;s not as powerful as the Helios 500 but it does have a Core i7 chip, GTX 1060 video and 512GB SSD option (or 2TB disk).</p>
<p>Australian pricing for the new Acer range has not been announced.</p>
<p>For those who prefer a desktop box over a notebook Acer is releasing the Predator Orion 3000 and 5000 workstations that come in a tower configuration.</p>
<p>You can configure with whatever your budget extends to.</p>
<p>From a Core i7, dual GeForce GTX 1080 Ti card and 3TB of storage (plus a 512GB SSD), to a smaller Core i5 chips and GTX 1050 graphics card.<a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_134935.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95313" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_134935.jpg" alt="" width="1670" height="812" /></a></p>
<p>Then there is the Nitro 50 which maxes out at a Core i7 and GTX 1070 but includes features such as a Qi wireless charging pad.</p>
<p>Both the Orion 5000 and Nitro 50 will be launched in Australia in the second half of the year.<a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_135010.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95315" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_135010.jpg" alt="" width="395" height="812" /></a><a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_135205.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95317" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_135205.jpg" alt="" width="1670" height="812" /></a><a href="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_135257.jpg"><img loading="lazy" decoding="async" class="alignnone size-full wp-image-95319" src="https://www.channelnews.com.au/wp-content/uploads/2018/05/20180523_135257.jpg" alt="" width="1821" height="885" /></a></p>
