The Acer Predator Helios 300 PH315-52 laptop with the Intel i7-9750h & nVidia 1660 Ti is a great performer. I've been using it as my daily work laptop with some occasional gaming for about a month. It replaced my Dell e6430.- It runs the latest games at above 60 fps with settings on high (generally speaking), usually much higher. PUBG runs at 95 - 105fps (non turbo), to 110 - 125fps (turbo) - 1080p, high settings.- The screen is excellent, 144hz IPS, and also works really well for Lightroom photo work. There is slight flex on open and close, I wish it was more ridged. It uses a metal lid and features the predator logo that is lit light blue at all times and cannot be turned off.- The keyboard feels decent for a chiclet keyboard, the keys have a positive activation feeling, are quiet, but feel slightly soft on bottom out. The back light can be turned off, but the 30 sec auto off setting cannot be adjusted. This version does not have and RGB back lighting, it's a light blue back light only. The keyboard deck, palm rest, and sides of the laptop are all one metal piece, there is no flex on the keyboard, which is excellent.- The touch pad feels really smooth, but the right/left click button areas require more pressure to activate.- Wireless card is a Killer Wireless 802.11ac i1550 (Intel 9560NGW) - Links at 866Mbps - I've not had any drop-outs or disconnects. Mainly used with Cisco APs and Asus RT3200-AC at home.- Ethernet jack is very difficult to disengage the CAT5 cable from, it seems to snag on the RJ45 connector. Luckily I don't need to use wired ethernet too often.- The web cam and mic combo are pretty standard and of average picture and sound quality. They work fine for the occasional Skype call.- The the model I got came with a 256GB M.2. 2880 SATA SSD B+M key (Kingston RBUSNS8154P3256GJ1)- Also came with 16GB RAM - 2 x 8GB Kingston ACR26D4S9S8ME-8 PC-21300 DDR4 / DDR4-2666 (1333Mhz) - 19-19-19-43 timings.- It's very easy to remove the bottom panel to gain access to an additional M.2 slot and SATA 2.5" storage bay, both RAM slots, and WiFi mini PCIe card.- The built in speakers produce pretty nice sound, they don't get as loud as I'd like them to be, but are perfectly adequate.- The fans are generally quite, when the system is used for web or light work, the CPU fan is slightly audible. During gaming they ramp up and get louder, and with turbo enabled, they get really loud, like a mini jet, and would be a definite annoyance for those around you. Head phones are recommend. I use turbo mode in PUBG, and it boosts frames anywhere from 10 to 15 extra fps.- The WASD area and palm rest don't get hot during gaming, just a little warm. The area above the keyboard and the num pad areas are where it gets hot.- On battery, I run the laptop in battery saver mode, and get about 4 hours, that's enough for a movie during a flight or several meetings of note taking / email / web.- While gaming I've noticed the battery will tick down while still on AC. I don't know yet if this is an issue. Searching around the web I've found reports that MSI and ASUS laptops do this too and it is by design; supposedly. During the course of a 3 hour gaming session in PUBG and turbo on, my battery drained to 75%. The drain is slower without turbo. I assume after the battery gets low enough, the CPU and GPU will throttle. I plan to reach out to ACER support for the official explanation.- I've picked up a spare AC adapter - included in photo, search Amazon for: 19.5V 9.23A AC Adapter Charger Power Supply for Acer Predator Helios 300 G3-571-77QK, G3-571 G3-572 PH317-51, Acer Aspire V17 Nitro VN7-793G, V15 Nitro VN7-593G Tip 5.5mm, Not Big Tip 7.4mm with Pin- It also fits nicely into Swiss Backpack - J14B-1H-A - 18.5 *12.5*7 (inches)So far I'm very happy with the laptop, it has excellent performance, very nice expandability, is comfortable to use and looks really good.
