Jeremy Q.TOP-NOTCH AFTER-SALES SERVICE!
I received my PC with a faulty graphics card, and the after-sales service from Flowup was ultra effective. They replaced my card the same day (shout-out to Mickael, who was genuinely great).
Lenny N.No regrets!
I invested in the BlackHawk and it’s pure bliss. With the Cooler Master MK770 keyboard and the MSI IMMERSE GH20 headset, it’s nicer than my bed. And yet I love my bed—honestly!
The after-sales service is really top quality. The responses and the help provided are quick, with kindness and a genuine human exchange.

Tristan X.a great discovery ...
I bought a custom PC on this site and I was guided really well regarding the use I wanted to make of it—but above all, I got value for my money.
I contacted the after-sales service several times to get a few answers, and they were very responsive. I highly recommend FlowUP for buying a PC.

I bought from Flow up.
I recently purchased a PC built by Flowup and the experience has been flawless. The build is ultra neat (perfect cable management), the components are quality, and the performance is exactly as advertised—if not better.
Special mention for the secure packaging: the PC arrived in perfect condition. I recommend it 100% for anyone who wants top-end performance without the 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 equipped with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB RAM. It’s perfect for gaming at 1440p in high/ultra settings on big AAA titles with 80/120 fps, and for esports at 240 fps in low/high quality (depends on the games).

amd ryzen 5 5600
The AMD Ryzen 5 5600 processor is an attractive option for mid-range PCs, suitable 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 L3 cache to 16 MB and PCIe support to 3.0 instead of 4.0.
