In today’s fast-moving world of PC hardware, power delivery isn’t just a technical detail — it’s the backbone of system stability, performance, and longevity. The Antec NeoECO Gold Modular 850W PSU brings this to life with precision engineering, modern design, and over 35 years of trusted innovation in performance computing.

Designed for gamers and system builders who demand more, the Antec NeoECO Gold 850W PSU combines cutting-edge performance with modular flexibility. At its heart is a high-efficiency, fully modular power platform built to fuel the latest high-performance CPUs and PCIe 5.0 GPUs, while keeping thermals and acoustics optimised.

With 80 PLUS® Gold certification, it delivers up to 92% efficiency under typical loads, translating to lower heat, reduced energy waste, and better overall system performance. It's powerful single +12V rail delivers over 99% of the PSU’s total output, ensuring stable, uninterrupted power for intensive tasks like gaming, rendering, and content creation.

Built on Antec’s PhaseWave™ design (a Half-Bridge LLC topology with DC-to-DC conversion), this PSU offers consistently clean, stable power. Synchronous rectification boosts reliability under fluctuating loads, while the included 12VHPWR cable ensures full compatibility with NVIDIA RTX 40 Series GPUs and PCIe Gen 5.0 — no adapters needed.

Cooling is intelligently managed by a 120mm Fluid Dynamic Bearing fan. Under light loads, Zero RPM mode keeps the fan off for silent operation. As demand increases, onboard thermal sensors automatically adjust fan speed, striking the ideal balance between cooling and noise.

Inside, the Antec NeoECO Gold 850W PSU is built with premium all-Japanese capacitors, delivering tighter voltage control, lower ripple, and outstanding durability — even under sustained load or high-heat conditions.

The fully modular cable system keeps builds clean and airflow efficient. Only plug in what you need. A forward-compatible 28(18+10) pin MBU connector supports next-gen motherboard standards, making future upgrades a breeze.

Antec’s CircuitShield™ safety suite provides full protection — including overcurrent, overvoltage, short circuit, inrush surge, and more — for complete peace of mind, whether you’re powering a pro-grade workstation or a high-end gaming setup.

All this is packed into a compact, matte-black chassis and backed by Antec’s 7-year warranty. The NeoECO Gold 850W isn’t just a PSU — it’s a long-term investment in stability, performance, and evolution.

  • Return of merchandise (RMA) and Warranty

    We want you to be happy with the purchase you have made from us. If you are not completely satisfied, you may return the product to us and we will either refund, credit, repair/replace it, subject to the below terms and conditions. 

    You can return purchases for a refund (excl shipping). Please notify us within 7 days and ensure item is ready maximum 10 days after delivery date.

    Please ensure to log your return request within 7 days of receipt of your item. Please ensure to select the correct reason for return:

    - Changed my mind / Item exchange

    - Faulty on arrival

    - Incorrect item received

    All items are covered by a 12 month warranty (unless otherwise stated) which will be honoured directly by GeeWiz. All products will either be replaced/repaired/refunded depending on stock availability. Products will require evaluation by GeeWiz before a warranty claim can be accepted.

    Should the item being returned for assessment be found to be in good working order, unfortunately, there will be a collection fee that will apply.

    The collection fees are as follows:

    - For returns on items that were sent with free shipping: R198

    - For returns that had a surcharge, the same surcharge will apply for collection.

    Please log your return on your account, under the returns manager.

    We do not reimburse your fee to ship to us, but we will pay for return shipping if the item is subject to replacement. If the item you wish to return was ordered incorrectly / is no longer required / you have changed your mind, there is a collection fee that will be charged (please refer to the above) and this will be deducted from the refund amount once the supplier has credited us. Please note GeeWiz will only cover return shipping of a faulty unit within 6 months of purchase, after which, a shipping fee (starting from R198) will be applicable to you for the return of the unit.

    Any disputes relating to ordered items being short/incorrectly shipped will only be entertained if reported to GeeWiz within 3 days of delivery/collection.

    Refunds are subject to inspection of item(s) - in some cases, items will need to be sent to supplier for evaluation and testing. This can take up to 15 working days. Once a refund has been approved, this may take 3 - 5 business days to be processed.

    ALL returns are subject to up to a 30% restocking fee if item is no longer in BRAND NEW condition or if item seal/packaging has been broken.

    Please re-package safely and include all original product packaging.  

    All software products are unfortunately not eligible for credit or refund once purchased.

    After the 6-month period, you will no longer be eligible and won't be able to receive a refund. We can however replace or repair depending on the outcome after our team of professionals has inspected the product.

    Should a warranty sticker not be present on an item, the warranty is immediately null and void.

    Batteries are covered under warranty, but please note that GEL, AGM and LEAD ACID have limited cycle runs. These are typically around 200 cycles and may run out before the end of the warranty. Once the cycles have been depleted, it means the battery has reached the end of life and will no longer be a warranty claim.

    GeeWiz reserves the right to refuse a refund if the item is damaged from misuse, items are missing, or if the product is altered in any way. 

    GeeWiz or its affiliates are not responsible for damage or loss of any kind that may occur as a result of using or misusing any product purchased from us.
