Will 650w handle this?

[MrAtlas]

Hi. I have a 650w corsair txm psu, wondering whether this upgrade will mean I have to get a new psu, different sites are telling me different things.

 

I currently have:

 

3600x, 2070 super, 500gb m2 nvme ssd, 2tb hdd, 16gb 3600mhz ram, 1440p 27" monitor, gaming mouse and keyboard. 

 

***Looking to upgrade the 2070s to 3080.***

 

Will 650w be sufficient?

 

(I won't be overclocking)

 

Thanks.

it's recommended to be 750W but that is covering PSUs in the bronze and below tier as well as platinum. It will be close with the TX650, Even when you aren't overclocking the GPU will boost above the listed clocks and that causes spikes in amperage which can draw more power than your PSU is designed for. 

 

personally, I would have no worries running a 3080 on that PSU as it's from one of the better manufacturers so it has quality components.

Probably not. Nvidia has stated that it's best to have a 750W minimum to power the 3080 in a complete system, and with some rare power draw spikes, even that's pushing it (as seen and stated before in a few of LTT's videos).

I ran a 5900X and 3060ti on a 500W for a while and sure, it'll run, but don't be surprised if your system overloads your PSU and your whole PC goes kaput. Like others said, spikes can be random and could knock your whole PC out mid-game. I stressed a 5900X and 3060TI at full blast and sure, it didn't quite take it out of my 500W PSU, but play it safe and say no, get a higher wattage PSU

It will run technically, but I would reccomend at least a 750 watt or more.
