Jeremy Q.Support is TOP!
I received my PC with a faulty graphics card, and the after-sales service from Flowup was ultra efficient. They replaced my card the same day (big shout-out to Mickael, who was genuinely great).
Lenny N.No regrets!
I invested in the BlackHawk and it’s pure joy. With the cooler master MK770 keyboard and the MSI IMMERSE GH20 headset, it’s softer than my bed. And yet I love my bed—believe me!
The after-sales service is genuinely high quality. Their responses and help are fast, with kindness and real human interaction.

Tristan X.great discovery ...
I bought a custom PC on this site; I was guided really well based on what I wanted to use it for. But above all, I got good value for my money.
I contacted the after-sales service several times to get some answers. They were very responsive, so I strongly recommend FlowUP for buying a PC.

I bought from Flowup.
I recently bought a PC built by Flowup and the experience has been flawless. The build is ultra clean (perfect cable management), the components are high-quality, and the performance is exactly as advertised—if not better.
Special mention for the secure packaging: the PC arrived in impeccable condition. I recommend it 100% for anyone who wants serious power without any hassle!Date of the experience: 13 February 2026

FAST DELIVERY AND EXCELLENT PERFORMANCE.
I received my PC in exactly 9 days! (Order placed on 10 February and received on 19 February). I’d like to thank the Flow Up team for their speed and honesty.
As for my PC, it’s the Savannah v2 with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB RAM. It’s perfect for playing 1440p at high/ultra quality on big triple-A games at 80/120 fps, and for esports at 240fps on low/high settings (depending on the games).

amd ryzen 5 5600
The AMD Ryzen 5 5600 is an attractive solution for mid-range PCs, suited for gaming as well as photo and video editing, while still offering an excellent value for money.
With 6 cores and 12 threads, it delivers solid performance and sits just below the Ryzen 5 5600X in terms of price. The Ryzen 5600 uses a chiplet design with 32 MB of L3 cache, bringing it closer to the 5600X, while the 5500 model, based on the 5600G, disables the integrated GPU, reducing the L3 cache to 16 MB and supporting PCIe 3.0 instead of 4.0.
