MOTHERBOARD: MSI Z97 PC Mate(MS-7850) (SOCKET 0)
MONITOR: Samsung S24E390

BATTERY: 600W

Look at any brand that offers a pure-sinewave output.
Especially newer psu's (past 10y) with active pfc, get killed pretty quick.

Dont believe ppl saying it doesn't make a difference, as i had to throw out a 150$ psu that had never seen any ocing/overload etc.
It died within 2 years (5y warranty), and event that corsair was willing to fix it, shipping cost (back) was almost half of a newer one from seasonic.
Was running on (a 1000VA APC UPS; simulated sine out) battery for about 10-30s couple of times a month, and about 5-30 mins once or twice every couple of weeks during power outages.

New unit is 800VA real sinus out, and so far psu is still running fine for 5y now, while oc the cpu (little),
and gpu (a bit more) without problem...

Look at 800VA and up. higher numbers will allow to run on battery longer, or even while gaming, which is nice, as it allows you to finish the game, and then shutdown the pc..
To "fully" match the psu, you would need around 1000VA or more.
