What’s Inside the XUM Legend Budget Gaming PC

I opened up the XUM Legend to see exactly what you’re getting, and there are both pleasant surprises and expected compromises. The component selection is typical for this price bracket, with XUM prioritising functionality over brand recognition.

The Ryzen 5 5600G is the star here – it’s a genuinely capable 6-core processor that handles productivity tasks brilliantly. The integrated Vega 7 graphics are where reality sets in. This isn’t a discrete GPU; it’s sharing system memory and offers roughly equivalent performance to a GT 1030 or RX 550. That puts it firmly in “esports at low settings” territory.

The dual storage configuration is smart. The 256GB NVMe drive (likely a DRAMless model) handles Windows 11 and a few games, whilst the 1TB HDD provides bulk storage. I’ve seen XUM use various brands here – sometimes Kingston, sometimes unbranded Chinese manufacturers. The 16GB of RAM is adequate, though I’d have preferred seeing the speed specification confirmed at DDR4-3200, as APU performance is heavily dependent on memory bandwidth.

The motherboard is almost certainly an OEM A520 board with limited features. Don’t expect robust VRM cooling, multiple M.2 slots, or extensive BIOS options. It’ll work, but it’s basic. The 500W PSU concerns me slightly – not for current power delivery (the 5600G draws under 100W), but for future GPU upgrades where quality matters immensely.

Performance Tests: What Can the XUM Legend Actually Do?

I tested the XUM Legend across various scenarios to establish realistic expectations. The Ryzen 5 5600G performs excellently in productivity tasks – Cinebench R23 scores around 10,500 multi-core, which is comparable to older 8-core processors. For office work, web browsing, and content consumption, this system is genuinely snappy.

Gaming is where the limitations become apparent. In CS2 (Counter-Strike 2), I achieved 60-75fps at 1080p with low settings and resolution scaling at 90%. Playable, but you’re making significant visual sacrifices. Fortnite runs at 50-60fps on performance mode at 1080p. Valorant is the sweet spot, maintaining 80-100fps on low settings where competitive players want to be anyway.

Modern AAA titles are essentially off the table. Cyberpunk 2077 at 720p low settings managed 25-30fps, which is slideshow territory. Hogwarts Legacy similarly struggled at 20-25fps even at 720p. The Vega 7 simply lacks the horsepower for contemporary demanding games.

Where this system excels is older titles and indie games. Rocket League hits 60fps consistently at 1080p medium settings. Minecraft Java Edition with moderate render distance maintains 60fps. Stardew Valley, Terraria, and similar indie titles run flawlessly. If your gaming diet consists primarily of esports titles and games from 2015-2020, the XUM Legend can deliver acceptable experiences.

The memory bandwidth limitation is real. With the Vega 7 sharing system RAM, I noticed performance improved by 10-15% when I manually enabled XMP in BIOS to ensure the RAM ran at full 3200MHz speeds. Out of the box, some XUM systems ship with RAM at 2666MHz, which significantly hampers APU performance. Check this immediately upon receiving the system.

Thermals & Noise: Surprisingly Reasonable

One advantage of APU systems is lower heat output. The 5600G’s 65W TDP means thermal management is relatively straightforward, and XUM hasn’t completely botched the cooling solution.

During gaming sessions, the CPU settled around 68-72°C, which is perfectly acceptable. The stock AMD cooler (likely the Wraith Stealth) manages the thermal load adequately, though it does spin up audibly under sustained load. At 42 dBA during gaming, it’s noticeable but not intrusive – roughly equivalent to a quiet conversation.

The case features two intake fans with aRGB lighting and one rear exhaust. Airflow is adequate for this low-power configuration. I measured internal case temperatures around 35-40°C ambient during gaming, suggesting reasonable air circulation. The aRGB lighting is controllable via motherboard software, though the OEM board’s RGB implementation is basic.

One issue I noticed: the case fans appear to run at fixed speeds rather than ramping with temperature. This means the system maintains consistent noise levels regardless of load, which some will prefer (no sudden fan ramp-ups) whilst others will find wasteful during idle periods.

Upgrade Potential: Room to Grow

The XUM Legend’s greatest strength is its upgrade path. This is a standard ATX-style build using retail components, meaning you’re not locked into proprietary nonsense like some budget pre-builts.

The GPU upgrade path is the most obvious. Adding an RTX 3050 or RX 6600 would transform this system, though I’d strongly recommend replacing the PSU first. A quality 550W unit costs £50-70 and provides peace of mind. The case has adequate clearance for dual-slot cards up to 300mm length.

RAM expansion is straightforward and beneficial for APU performance. Moving to 32GB (2x16GB) at DDR4-3200 or even DDR4-3600 would provide more memory bandwidth for the integrated graphics and future-proof the system. This is a £40-50 upgrade that makes sense.

The storage situation is workable but not ideal. With only one M.2 slot, you’d need to replace the existing 256GB drive to upgrade to a larger NVMe SSD. The 1TB HDD is fine for bulk storage but noisy. I’d recommend replacing the 256GB SSD with a 1TB NVMe drive (£50-60 for quality models) and keeping the HDD for archival storage.

Build vs Buy Analysis: Is the XUM Legend Budget Gaming PC Worth It?

This is where budget pre-builts get interesting. At this price point, the convenience premium is minimal, but you’re also getting minimal performance. Let me break down the mathematics.

Here’s my component breakdown for DIY comparison: Ryzen 5 5600G (£110), A520 motherboard (£50), 16GB DDR4 (£35), 256GB NVMe (£20), 1TB HDD (£25), 500W PSU (£35), case with fans (£40), WiFi adapter (£15). That’s £330 in components, plus you’d need Windows 11 (£15-100) and thermal paste if not included. You’re looking at £345-430 depending on Windows licensing choices.

The XUM Legend at around £400 includes assembly, warranty, and activated Windows 11. That’s fair value, though not spectacular. The warranty is worth something – two years of parts and labour coverage plus 60-day returns provides peace of mind for non-technical buyers.

However, I must emphasise: if you can stretch your budget to £500-600, you’ll access systems with actual dedicated GPUs that offer 2-3x the gaming performance. The jump from integrated graphics to even an RTX 3050 or RX 6600 is transformative. The XUM Legend makes sense only if £400 is your absolute maximum and you understand the gaming limitations.

Warranty & Support: Better Than Expected

XUM’s warranty offering is surprisingly comprehensive for a budget brand. Let me detail what you’re actually getting.

The two-year parts and labour warranty covers manufacturing defects and component failures. XUM handles warranty claims through Amazon initially, then directly for issues beyond Amazon’s return window. I’ve heard mixed reports about response times – some users report quick replacements, others mention week-long waits for responses.

The 60-day refund period is generous and exceeds Amazon’s standard 30-day window. This gives you adequate time to test the system and ensure it meets your needs. The “lifetime tech support” claim is marketing speak – it means you can email questions indefinitely, not that they’ll repair the system forever.

One practical note: XUM doesn’t void warranty for user upgrades like RAM or storage additions, which is excellent. However, if you replace the PSU and subsequently have issues, they may argue warranty voidance. Document everything and keep original components if you upgrade.

Support is primarily via email, with phone support available during UK business hours. Don’t expect the responsiveness of established brands like CyberPowerPC, but for a budget brand, XUM’s support is adequate. The Amazon purchase route provides additional buyer protection through Amazon’s A-to-Z guarantee.
