Troubleshooting suggests I should try replacing the dubious power supply that came with my Lenovo K450e. (Admittedly the motherboard might be wonky). I'd like to know if I'm choosing a workable power supply replacement.
Misadventures with intermittent soft booting described here. Speccy description of computer here.
The existing system contains the original 250W Liteon. Internet website suggests that recommended PSU Wattage for my system is 231W, which seems to me to be cutting things pretty close. The OEM provided NVIDIA GeForce video card calls for a 300W minimum system power requirement, FWIW.
I'm thinking of purchasing a Cosair 450W, 80 plus Bronze certified with a 5 year warranty. I would buy it from Newegg.com, which has a 30 day return policy albeit with a reasonable 15% restocking fee for opened packages.
In the future I might add a 2nd hard-drive. I won't be upgrading the vid card.
Running Windows 10 Home 64 bit on an Intel i7.
Will this work? (Is there anything I need to check to be sure this is the right equipment?)
ATX? EPS? What's that?
Any advice is appreciated; I haven't replaced a power supply before.
