So I'm finally deciding to build a new system and I would be getting a Sapphire Radeon R9 270X.

 

By the time my computer is all built it's going to have:

 

16GB RAM

Intel® Core™ i5-4440

MSI H81M-E33

Antec VP-450 450 watts

Sapphire Radeon R9 270X

Windows 8.1

2 SATA Drives

1 CD ROM

 

Will I have enough power to run the Sapphire Radeon R9 270X and then some?

I'm running a 285 on a 500w so you should be fine, cutting it a little close on the 'and then some' though for anything worth while..

I would not recommend getting a 270x, It is just a 270 but overclocked from factory.

Id say you should step down to the 270(The performance is similar) Or stepping up to the R9 280.

R9 270 vs 270x vs 280(Give or take 10% since it is a synthetic benchmark.

You should be fine with that PSU.

I'm not sure I like running that close. If the power supply can supply 450W but 80 percent efficiency, it would be about 360 watts.

I think I will get the normal 270. It only takes around 150 (correct me if I'm wrong).

That is not how it works. The power supply still supplies 450W, but with an 80% efficiency that means it has to draw 560 watts from the wall to reach that wattage.

Thanks! There a misconception about power supplies out of my head.

Who knows. Maybe by the time I have my system built I might have a better power supply.
