Hi to every one,
I need some advice from you about a new power supply. At least 1000w but preferably 1200w with 4 pci express eight pin (ATX Motherboard with 24+8 pin configuration). Maximum budget: 350$

My actual system:
Intel Core i7-4790K
Asus Maximus VII Formula
16 GB DDR3
Sapphire AMD Radeon RX Vega 64 Liquid cooled
1 TB SSD
2x 1 TB HD 7200 RPM
LC-Power 1050 1000w Legion power supply (that started to be unstable and making noise...little ticks)

I would like a 1200w PSU taking into account future changes on my system. E.g. a second graphic card in crossfire and, more in the future, processor and motherboard.

Having said that I'll like to ask a second advice: my previous GPU (that I've not sold yet) is a R9 295x2 and I would like to know if it's possible and it makes sense to use that card in crossfire along my actual RX Vega 64 liquid cooled (at this point it will be a 3-way crossifre being the 295x2 a dual GPU). My concerns are about the fact that the new board has 8 GB of ram for a single gpu and the old one 8 GB but shared between 2 GPU2 and about the fact that the motherboards only support 16 PCI Express lanes that means that the 2 cards would be running at 8x (not a big deal the latter being 16 lanes pretty difficult to saturate.

Thanx in advance
Marcello
