AX850 Gold w/ 650 ups

[babelmh13]

So a couple weeks ago, upon adding a second gtx 670, every 5 minutes or so, my ups would long beep. So my guess is that now, my system power must be drawing more than 650 watts. But that was only happening playing bf4. The only thing im switching now is my pump to an mcp655 and 1 120 rad and coooling the graphics cards. I dont thinkkk i will need to get a bigger power supply? And i guess ill need to sell my 650w ups and upgrade.. Really dont want to spend the extra money on it but mine is useless on my rig now

Your pc probably uses around 550 watts at max load. Even more if including LCD and speakers wattage. An 1100 VA UPS can support 660 watts (approximate 60% correction factor). An 1300 VA UPS can support 780 watts. Your AX850 can support peak 765 watts. It's fine. Get a new 1300 VA or higher UPS.
