[SOLVED] What PSU for AMD RX series?

[allextherat]

Hi, today I saw the AMD RX 580 and RX 570 are at the same price. I realy wanna buy one of this GPU (Rn I own an GTX 750 Ti)
So I know AMD is a huge "electricity eater" so I have a question.
I have a Corsair PSU with 550W.( Corsair NEW VS Series VS550)
Is this enough for RX 570 or RX 580? (4GB VRAM Both)

CPU AMD RYZEN 3 1300X (Stock)
8GB of Ram (Next month I will put 8 more gb of ram 2400mhz)

P.S It will bottleneck my CPU?

If you're looking at the RX570, you should be...ok. If the RX580, then you're going to need headroom. Also, if I were you, I'd replace the VS with a more reliable/robust unit(by Corsair) like the TX series. If you're on an A series of chipset board, then don't bother with higher ram speeds. If a B450 chipsetted board, then sure, you're able to look at DDR4-3200MHz ram kits.

Oh sorry I forget to mention my Mobo, is it a MSI B350M PRO VD Plus.
Actually I dont have the money to buy a new PSU, just exactley for a new GPU and more 8Gb of Rams.

I actually ordered the RX 570 4GB Edition, It was at the same price with RX580 4GB, but I don't have enough money to buy a new PSU so I choosed rx 570, I saw some benchmarks and the difference is like -10/12 fps.Not that much as I expected
