My old APC Back-UPS was fine when i first started, had only my monitor and PC hooked up to it. When I Started playing FF14 last night the alarm started going off and sure enough with the video card kicking up its drawing too many Watts. I think this one tops out at 380. So I unhooked the monitor from the battery. This morning I started playing Far Cry New Dawn and when the game gets into actually playing its drawing more than 380 watts just from the tower. So the next step up is 450 watts I believe. You guys think thats enough, or do i need to go higher?

Just the card and CPU can possibly pull close to 350 , keep that in mind.
And the PSU is poor quality.

My old system has a CORSAIR TXM Series, TX750M, 750 Watt, Semi Modular Power Supply, 80+ Gold Certified thats less than a year old, think it'd be a good idea to replace the atng? I usually build my own systems but I'm just tired of doing it and bought a prebuilt. Didnt realize they put a crap PSU in it till you pointed it out.
