PSU for my Vega 64

[DEL 707]

I built this PC last month.

Ryzen 7 Eight Core 2700X 4.35GHz (Socket AM4) Processor
Samsung SSD 850 Evo 1TB
Toshiba 2TB P300 7200RPM Performance Hard Drive (HDWD120UZSVA)
MSI Optix G24C 24" 1920x1080 VA FREESYNC 144Hz 1ms Curved Widescreen Gaming Monitor
OcUK Value Blu-ray / DVDRW combi SATA
Phanteks Enthoo Pro M Glass Midi Tower Case
Bitfenix Formula Series 750W 80 Plus Gold Power Supply
Alpenfohn Ben Nevis Advanced CPU Cooler - 130mm
Gigabyte Aorus RGB 16GB (2x8GB) DDR4 PC4-25600C16 3200MHz Dual/Quad Channel Kit
Gigabyte Radeon RX VEGA 64 WindForce OC 8GB HBM2 PCI-Express Graphics Card
Gigabyte Aorus GA-AX370-Gaming K7 AMD X370 (Socket AM4) DDR4 ATX Motherboard

I've been having troubles with loss of display, I've asked OCUK support and they suggest the problem could be the PSU.

These cards need ideally single rail high power delivery bandwidth PSU's or you can encounter issues as you have said.

Can anyone recommend a PSU to replace my Bitfenix 750W?

It used to shut down the PC, but that was when I was running the graphics card off a single line, rather then 2.
At the moment the machine keeps working after loss of picture. Sometimes the picture will come back, other times I need to restart the machine.

Sorry, can't remember what time it happened, and I'm not show what Power Save profile is.

I was talking to some people about this when it started happening. I've increased power limit and lowered the voltage to the GPU and memory.
I'm talking the tech support at OCUK and they still reckon it could be my PSU.

Would this be up to the job?
