I am planning to buy the MSI RX 480 4GB, I am trying out AMD's new flagship gpus. I have little knowledge of AMD, but will the Corsair VS450 be enough for the RX 480? My specs are:

CPU: i5 4440
RAM: Corsair Vengeance 8GB
PSU: Corsair VS450
Motherboard: ASRock H81M-DGS
Current GPU: GTX 1050 Ti OC

1. The MSI is probably the best performing 480 out there... TPU said it was the 1st 480 that could give the 1060 a run for the money.

Out of the box, the [MSI 480] card is overclocked to a frequency of 1303 MHz, which is not a lot higher than the AMD reference of 1266 MHz, but throttling is reduced, which effectively increases clocks by 50 MHz when looking at the average clock in gaming states. As a result, the card is 4% faster than the RX 480 reference and 6-7% slower than the GeForce GTX 980, GTX 1060, and Radeon R9 Fury, which all have roughly the same performance at 1080p....

... this $25 increase [over the reference 480] is not unreasonable if you...

... this $25 increase [over the reference 480] is not unreasonable if you consider how much better the MSI RX 480 Gaming X performs in every single test in this review. In my opinion, this is thus far the only RX 480 that looks like it can compete with the GTX 1060 and its custom designs.

As you can see here....

In typical gaming, the card draws 196 watts and peaks at 224 watts

Compare that with the 1060 which draws 121 watts and peaks at 125 watts

So we are talking a difference of 75 - 99 watts.

Guru3d recommended a 450 watter for the MSI 480 ... The VS series is Corsair's "Builder" aka "low budget" series so that's a PSU I would not want to recommend using at it's upper limit ... so I'd be a bit wary and certainly no overclocking.

You might consider the MSI 1060 which pulls 75 - 100 watts less, it is a bit faster so you will pay a bit more but you'd get it back in electricity savings if that matters.
