Acer Predator GX850 SFX PSU Review | Leading Edge

The 80 Plus Gold-rated SFX PSU in the Acer Predator GX850. But instead of creating a bare-bones unit, the company has introduced an 850W SFX power supply for gamers, enthusiasts, and small-form-factor PC builders. Features include ATX 3.0 support, PCIe 5.0 connection, and an 80 Plus Gold rating in a fully modular design.

You also get the GX850, which is tuned for use in modern systems with power-limited graphics cards. Due to its SFX form factor, the power supply fits inside Mini-ITX and other compact PC cases while still delivering ample power.

This review will look at design, performance, cooling, power efficiency and value. We are also going to talk about what it has going for it, as well as the things that make you question whether this PSU is the right choice for your next build.

Now, let’s take a look at its features and specifications.

·         850W continuous power output

·         SFX form factor (100mm length)

·         ATX 3.0 and PCIe 5.0 ready

·         80 Plus Gold certified efficiency

·         Fully modular cable design

·         Native 12VHPWR connector included

·         Single +12V rail rated at 70.83A

·         Supports modern NVIDIA and AMD GPUs

·         92mm cooling fan with semi-fanless mode

·         Japanese capacitors on major stages

·         SFX-to-ATX adapter bracket included

·         100-240V universal input support

·         Built by the FSP platform design

·         Strong voltage regulation and ripple suppression

Acer Predator GX850: the compact design is compliant with standard SFX dimensions (100 mm long), so it is well suited to smaller gaming systems. It may be compact, but it feels solid, almost reassuring in its heft.

Moreover, the PSU has a glossy black finish, which makes it look neat and high-end for most tasks. Branding is pretty understated, so it will fit well in most PC builds. It is completely modular, which gives you a lot more leeway with cable management — particularly in small-form-factor cases. The cables are thin and pliable for a snug fit. Acer also provides an SFX-to-ATX adapter bracket for this power supply, should you ever need to install it in a standard ATX case.

Where the GX850 begins to impress is not in its features, but rather in its performance. Though this is Acer's first point-of-sale PSU, it delivers the very best in stability.

It can deliver its full 850W output continuously. In some cases, the voltage regulation is as tight over the whole power delivery chain. In testing, the PSU demonstrated solid electrical performance, with stable power delivery even under heavy gaming and workstation loads.

Moreover, ripple suppression is also excellent. The clean power output protects high-end components like graphics cards and processors, which can be rather pricey. So, users considering systems paired with high-end GPUs like the RTX 5080 or beyond, and PCIe 5.0 graphics cards in the future, should have some peace of mind with this PSU.

The Acer Predator GX850 has an 80 Plus Gold rating. Consequently, it provides good efficiency over an extended load range. Most situations see more than 90% efficiency at typical gaming loads. This translates to less energy wasted, resulting in even lower heat and less electricity consumption.

Moreover, the PSU performs especially well at or near the 50% load threshold observed with most gaming systems in day-to-day use. That way, users are assured of performance and efficiency.

A 92mm double-ball-bearing fan handles cooling. In semi-fanless mode, the fan remains off during light workloads. As a result, web surfing, word processing or video playback is almost silent. When power demand increases, the fan kicks on to keep temps safe.

However, there is a downside. The fan becomes much louder than some of the competing higher-end SFX power supplies at loads above ~700W. Given the stepped, rather than continuous, increase in the fan profile, noise becomes more of a consideration when pushed into performance-heavy processes. That said, temperatures are still manageable and thermal performance is quite good from such a small package.

We can tell right away that the GX850 is most beneficial due to its compatibility. It features a native 12VHPWR connector and support for the latest ATX 3.0 standard. So users: No adapter required for next-generation graphics cards. With an overall capacity of 850W, it's extremely capable of powering high-performance CPUs and GPUs simultaneously.

This strength lies in the robust thermal management. Internally packed, but air still gets through. Also, the double-ball-bearing fan is designed for long-term durability. It often lasts longer than sleeve-bearing alternatives, too, especially in small systems that run hotter.

For long grinding gaming sessions, the internals also stay within safe temperature thresholds. While we do hear the fan ramp up a bit under heavy load, it does not allow ambient heat to build up.

Acer used the GX850 platform from FSP. This is crucial because FSP is one of the most trusted PSU makers in history. Consequently, it leverages proven engineering and reliable internal components. Such protections are useful to prevent precious PC hardware from sudden electrical problems.

Here is what it offers:

Pros

·         Compact SFX form factor

·         Powerful 850W output

·         Fully modular design

·         ATX 3.0 and PCIe 5.0 support

·         Native 12VHPWR connector

·         Strong voltage regulation

·         Excellent ripple suppression

·         High efficiency performance

·         Semi-fanless operation at low loads

·         Quality internal components

·         Includes SFX-to-ATX adapter

Cons

·         Fan becomes loud under heavy load

·         Fan speed curve is somewhat aggressive

·         Cable lengths may be short for large ATX cases

·         Faces strong competition from established SFX PSU brands

The Acer Predator GX850 SFX PSU is an unexpectedly promising first showing from Acer. In a small form factor, it pitches nifty features for ATX 3.0, solid electrical performance and stable power delivery.

Additionally, the 850W capacity makes it ideal for modern systems and compact, high-performance PCs. The 12VHPWR connector in its native form ensures compatibility with both existing and future graphics cards.

Under heavy workloads, the cooling fan can get a bit loud, but overall, it delivers impressive performance. Then the Acer Predator GX850 is worth a serious look if you are building a Mini-ITX gaming PC or just making a powerful small-form-factor workstation.

Overall, the Acer Predator GX850 is a reliable option for users looking for a compact, efficient and feature-rich SFX power supply without compromising on power.
