A:AnswerThe computer currently has 16 gigabytes of RAM in two 8 gigabyte modules, so to upgrade the RAM you'd need to remove the RAM that's in the computer and replace it with higher capacity RAM. You'll need to get one or two DDR4-3200 UDIMM modules. You can get either 16 or 32 gigabyte modules, depending on how much you want to increase the RAM.
A:AnswerI'm not seeing a 600 watt power supply listed in the available parts, but your best option would be to contact the HP support team to ask if there's a power supply that has that capacity and is compatible with the computer.
A:AnswerThank you for asking. Yes, the Victus 15L TG02-0130 is highly upgradeable, with 2 M.2 slots (1 for SSD, 1 for WLAN); 1 PCIe Gen 3 x16; and 1 PCIe Gen 3 x1 slots. It supports up to 32GB RAM.
A:AnswerYes, you can. The computer has a 500 watt power supply, so you'll be able install a video card that doesn't run the system wattage over 500. And yes, you should have no problem running Spiderman on this computer.
