Acer Predator Helios 300 (PH317-55): Full Specs / In-depth Review

4 reasons to BUY the Acer Predator Helios 300 (PH317-55)

1. Design and build quality

With a mostly aluminum build, the laptop leaves a good impression with its durability. While there were some flexes from the lid and the chassis, we hardly think that any laptop with such dimensions wouldn’t flex. The design has some minimalist qualities, such as the flat-shaped lid and base, but the Predator logo on the lid and the aggressive heat vents quickly give away its gaming nature.

The lid opens with a single hand, revealing a display with thin bezels and an HD Webcam. The base houses a pretty good keyboard + touchpad setup. The unit has large keycaps, long key travel, and clicky feedback. The WASD and Arrow keys are colored in Blue, while the whole keyboard has a 4-zone RGB backlight. The touchpad has a decent size and a smooth cover, which makes gliding effortless. The tracking is responsive and accurate.

2. Upgradeability

The laptop features two SODIMM slots, two M.2 PCIe x4 drive slots, and a 2.5-inch SATA drive bay. The RAM slots are hidden behind a metal plate, being able to house up to 64GB of dual-channel memory. Thankfully, Acer includes the necessary cables in order to connect a SATA drive in the box.

Here is our detailed teardown video, which shows how to access both the RAM, M.2, and SATA drives.

3. Display quality

The IPS display of the Acer Predator Helios 300 (PH317-55) has a 17.3-inch diagonal, Full HD resolution, and a 144Hz refresh rate. Furthermore, the viewing angles are comfortable, and the brightness is incredibly uniform across the entire area of the display. The maximum brightness caps at 314 nits in the center of the screen, 309 nits for the entire display area, and a maximum deviation of 2%. The contrast ratio is quite high – 1520:1. In terms of color coverage, the panel covers 96% of the sRGB color gamut.

Going over to the color accuracy, we had a dE value of 4.5 with the factory settings, which improved drastically once we applied our Design and Gaming profile. Here are the results with (right) and without (left) our Design and Gaming profile applied.

In addition to receiving efficient and health-friendly profiles, by buying LaptopMedia's products you also support the development of our labs, where we test devices in order to produce the most objective reviews possible.

Office Work

Office Work should be used mostly by users who spend most of the time looking at pieces of text, tables or just surfing. This profile aims to deliver better distinctness and clarity by keeping a flat gamma curve (2.20), native color temperature and perceptually accurate colors.

Design and Gaming

This profile is aimed at designers who work with colors professionally, and for games and movies as well. Design and Gaming takes display panels to their limits, making them as accurate as possible in the sRGB IEC61966-2-1 standard for Web and HDTV, at white point D65.


Health-Guard eliminates the harmful Pulse-Width Modulation (PWM) and reduces the negative Blue Light which affects our eyes and body. Since it’s custom tailored for every panel, it manages to keep the colors perceptually accurate. Health-Guard simulates paper so the pressure on the eyes is greatly reduced.

4. I/O

The laptop has decent I/O coverage, although it’s not without its shortcomings. For example, the lack of a MicroSD card reader might be a bummer for a lot of people. On the other hand, you get Thunderbolt 4 support, three USB Type-A 3.2 (one Gen. 2 and two Gen. 1) ports, an HDMI 2.1 connector, an RJ-45 connector, and a 3.5 mm audio jack.

1. Battery life

The laptop offers disappointing battery life, which is to be expected from a unit with a measly size of 55Wh. The laptop lasts for 5 hours and 52 minutes of Web browsing and 4 hours and 46 minutes of video playback. The way we conduct our battery tests is with the Windows Better performance setting turned on, screen brightness adjusted to 120 nits, and all other programs turned off except for the one we are testing the notebook with.
