PCSpecialist Zircon Master R Prebuilt Review (7900X/6800 XT)

Rating: 8.0.

Cast your mind back the best part of two years and you may recall that I reviewed the PCSpecialist Vidar with Ryzen 9 5900X and RX 6800 XT graphics. Today the time has come for an update to a Zen 4 CPU and we also got to play with Samsung's latest 990 Pro SSD. Sadly the price has crept up from £2,200 to £2,849 which is quite clearly a sign of the time.

It is fairly obvious that a pre-built PC is the sum of its parts and then we take account of the build quality and price. In the case of the PCSpecialist Zircon Master R this is doubly true as we have reviewed most of the components in recent times. Luke is working on the Ryzen 9 7900X right now but has reviewed the 8- and 16- core models HERE and the Ryzen 5 7600X HERE. Luke also reviewed Corsair Dominator Platinum RGB DDR5-5200 HERE and the Corsair H150i Elite CPU cooler HERE. Simon has reviewed both the Samsung 980 Pro SSD HERE and the 990 Pro HERE and I have reviewed the Corsair iCUE 5000T RGB HERE. The final piece of the puzzle is the graphics card which has an identical specification to the reference RX 6800 XT that Dominic reviewed HERE.

PCSpecialist has done a tidy job with the build and has configured Corsair's iCUE software to provide a Rainbow Marquee light show along with cooling air flow that keeps the Ryzen 9 7900X under control.
