Recently Seasonic updated their flagship PRIME Titanium and Platinum series of power supplies and today we take a look at another model in these ULTRA ranges – this time in an 850 watt capacity. Their expensive 1000W Ultra Titanium unit impressed us immensely, but is the cheaper 850W Platinum another unit you need to consider for a new system build?
It seems I am constantly singing the praises of Seasonic, but its impossible to actually find a bad unit in their portfolio. I don’t think I could say that about any other manufacturer. Their recent pairing with Phanteks will be interesting to watch in 2018.
Its worth pointing out that Seasonic supply these review units from Amazon so they can’t really be considered ‘golden reviewer samples’. They arrive at our doorstep in an immediately recognisable Amazon box we all know and love.
