Question HTPC keeps rebooting

[velocci]

Hi all, I have this old PC that I use as an HTPC. It has an MSI 1050 Ti video card in it, an SSD and HDD. I keep the PC on all the time and it never reboots. it only reboots when i'm watching a movie from it. Its plugged into my AVR. I used a website that calculates how much power your PC uses and recommends how many watts your PSU should have. It calculated 300 watts and recommended that I use one with 350 watts. I realized the other day that the PSU in it only has 280 watts. Is this why the PC keeps rebooting?

I assume you're dealing with a prebuilt system? If so, what is the make and model of your prebuilt and include it's SKU. The issue you've stated is caused from a lack of power/failing PSU, when the system is taxed.

yes its a prebuilt PC. Its a Lenovo M90p. the type is 5498-RW8

Sounds like you might be lacking in terms of power.

is there a good, quiet PSU at about 600 Watts? I know I don't need that much power, but I will build a new PC soon and so I'll use this new PSU for it when I build it. In the meantime, I can put it in my HTPC so it doesn't reboot.
