A better choice would be the Gigabyte Aorus P750 750w. This one has a 10 year warranty compared to the Bitfenix Whisper M's 7 years. It's a fiver cheaper too plus you get a extra 100w. It's gold rated and fully modular with black ribbon cables and has excellent quality internal components. The downside is that every cable has capacitors sticking out of them. The Bitfenix Whisper M has them on the 24 pin cable but they are covered by a large shroud. On the Gigabyte they stick out of the plugs. Supposedly they are there to give cleaner power delivery but surely they could have come up with a better solution. It's still a excellent psu though.
My basket at Overclockers UK:
Avoid a budget psu at all costs especially with a power hungry card suce as Vega. One thing I will advise is that whichever psu you end up with power the Vega with two seperate pci-e cables and don't power it from the pair of leads on a single cable. Using a single cable with Vega be it a 56 or 64 can throw up stability problems. This is sorted by using a single connector from two seperate cables. This is also a reason to get a psu above 550w because 550w and under usually only have a single pci-e lead.
