Will I be able to get away with a 500w PSU for this build for a month?

inQntrol · May 30, 2017

Hey,

I'm upgrading my system on a monthly basis and I am planning on purchasing a GTX 1080Ti to pair with my i7-7700k, 16GB RAM system but I won't have enough money to purchase a PSU if I decide to go for the 1080Ti at the end of june.

So, if I did end up going with a GTX 1080Ti, would I be able to get away with using a 500w PSU for atleast a month without any problems, or it is just better to buy the power supply first and then purchase the 1080ti the month after?

PC Part Picker says the power draw would be 485w at its highest, but I'm not sure how accurate that would be.

A "good" 500W PSU? Yes.

A CX500 Builder? I'd say No.

I'd pick up a quality PSU first of all.

I would say no considering that is a builder series.

Would be absolutely nonsensical mate.
Youre picking one of the most expensive 1080ti's out there ,
the standard strix is £80 cheaper & its got abouta 300mhz lower baseclock.

That £80 will buy you a good quality 650w psu at the same time.

For those who are thinking I'm going to buy a 500w PSU, I'm not, I'm planning on buying an RMx 850 from corsair,. I already have the 500w psu from my old build thats why I'm asking if it's an alright option instead of purchasing one straight away. I mean this CX500 i have right now is around 5 years old.

I might be buying another 1080Ti a few months after I get this one at the end of june for 2 way SLI so I would need a larger wattage PSU but I don't know if it was absolutely necessary now since I could possibly get away with using my CX500

@madmatt30 made me see a problem i was making in my purchases, I was buying the more expensive strix and i completely didnt notice.

I made a small adjustment and now I can afford an RMx850 and 1080Ti strix.
