Alphasync Prebuilt Review: Ryzen 7 9800X3D and RX 9070 XT
Ebuyer has relied on AMD for the central components in this AlphaSync Prebuilt Gaming PC. The CPU is a Ryzen 7 9800X3D, which is the best gaming processor that money can buy while the graphics are Radeon RX 9070 XT. Our review PC came with a Sapphire Pulse graphics card and the result was a fine gaming experience. In the main we were very happy with this PC but we came across a couple of quirks during our review and one of them could well be a deal-breaker.

Testing and Performance
Geekbench 6 Multi Core
In Geekbench 6 Multi Core we see the AlphaSync Prebuilt Gaming PC performs at exactly the level we saw in our review of the Ryzen 7 9800X3D, which is precisely what we expect.
AIDA64 Memory Bandwidth
AIDA64 Memory Bandwidth throws up an interesting result as the Corsair Vengeance DDR5-6000 memory kit performs very well.
Cyberpunk 2077 at 1080p
Cyberpunk 2077 at 1080p shows the AlphaSync Prebuilt Gaming PC performing well, the results are good and very playable.
Cyberpunk 2077 at 1440p
When we turn up Cyberpunk 2077 to 1440p, the GPU can't match an RTX 4090 – as we'd expect – but nonetheless the frame rate is very good and the gaming experience is great.
Closing Thoughts
The component parts used in the AlphaSync Prebuilt Gaming PC are solid choices from reputable brands, however the motherboard lets the side down. We don't mind the choice of B650 chipset over X670, B850 or X870 however the features of this Asus Prime are very basic. The absence of USB-C ports on the rear I/O panel crosses a line that we cannot forgive and we hope to goodness that Ebuyer ups the spec of this system, even if that costs an extra £100 on the retail price.
We were very happy with the build quality of the AlphaSync Prebuilt Gaming PC and could find no flaws. On the configuration side of things we raised a question over the absent software from Asus and Corsair as we expect to be able to control RGB software. The solution, as you can see in our video, was to do the job ourselves and the end results were very pleasing.

Pros
- Good gaming performance.
- Build quality is very good.
- Plenty of SSD storage is included.
- Pricing is fair.
Cons
- There are no rear USB-C ports and only one at the front.
- Armoury Crate and Corsair iCUE not installed so RGB lighting is fixed.
KitGuru says: AlphaSync Prebuilt Gaming PC is decent enough but is let down by the USB support.
