The eXtreme Power Supply Calculator says load 263 W, recommended 313 W. The PSU is 300W. Should I try this setup?
My mother's PC's GPU is terrible. She can't even use Chromecast properly. I now have a spare GPU that run Chromecast fine. (I wouldn't have expected Chromecast to be affected by the GPU, but her PC couldn't run it at all without a GPU. Also, when I run it on my PC, the TV displays some little graphical glitches that my old GPU did sometimes, but her PC does not cause this. Also, GPU options in Nvidia Control Panel or CCC affect the TV output.)
(Now I have a GTX 950, so the 3870 is spare)
Intel Core 2 Duo E7600 3.06 GHz
2 GB DDR2 RAM
Gigabyte GeForce 9400 GT
IDE CD/DVD burner
FSP Group 300W PSU
Planning on swapping the 9400 for a Sapphire Radeon HD 3870 512 MB. The PSU has no 6-pin connectors, so I could use the 2x Molex to 6-pin adapter I have.
EDIT: Don't say buy a new PSU. She'd be better off keeping the 9400 in that case and I'd just have to use my PC for Chromecast (it's only one site that lags for her, most are fine) If the only way to run the 3870 is with a new PSU, then I may consider one and carry it over with her new system, which may get built in the next couple of years.
