I am looking to replace my old PC running 3 monitors and three SATA 7200RPM hard drives with a Dell XPS 8700 also running 3 monitors and 3 HDs. . The new Dell has an Intel i7 4790 CPU. I will be adding DDR3 memory to bring it up to 32GB. I will also be adding 2 external hard drives as backups via USB 3.0. I noticed from the specs that it comes with a 460 watt PSU. It also comes with a NVidia Gforce GT720 video card which, according to the pictures, looks like it has hookups for 3 monitors already.
Usually, when i get a new PC, i replace the stock 300 watt PSU with a 500 or 600 watt, add the 2 additional hard drives, then add the video card for the 3 monitors and add additional RAM if desired.
It looks like i won't have to add the video card and i'm HOPING i can get by with the stock PSU since it's 460 watts. I'd love to not have to mess with replacing it if i don't have to. I don't do gaming on my PC but i do watch videos and also edit DVD and Divx videos on it.
I'm assuming that, since this new PC comes with a graphics card with hookups for 3 monitors, the 460 watt PSU is made to handle that. Is that a safe assumption?
So, with adding 2 additional internal SATA hard drives, 2 external hard drives, 3 monitors, and extra 16GB of DDR3 RAM to bring it up to 32, do you think i'll still be safe with the 460 watt stock PSU?
How will i know if i need more power? Is there a good software you can recommend to monitor PSU usage? Also, what sort of signs should i be looking for that indicate that the PC needs more power?
