One overview for this exact edition. Confirmed delivered totals come first; unknown charges remain unknown.
No current verified shop price. Check specifications and alternatives.
Different marketplace sellers or observations may appear separately. No delivery-time or shop-rating claim without supplied evidence. Check seller, warranty and delivery before paying. Commercial links may earn commission; this never sets their order.
No confirmed price measurements yet. The chart starts with the first observation.
We never reconstruct a price history from an advertised discount.
History contains saved model measurements, not every shop inventory update. A newer current shop price may differ from the latest chart point.
Your account tracks saved, verified model totals against the target. Shop inventory can contain newer prices.

The exact EU edition has useful electrical test evidence. Check GPU connection, cable set and case clearance alongside rated power.
A good fit forYou need this specific EU PSU and have checked connections, load and clearance.
Look further ifYou expect cables or features from a later RMx or RM850e without checking.
Start with full code CP-9020200-EU: this is the EU-cable edition of the 2021 RM850x. The existing North American variant and later RMx models remain separate products.
An independent test identifies this exact EU code and favourably assesses voltage regulation and ripple under its test load. That is more relevant to electrical assessment than home anecdotes, but does not establish every unit’s lifespan.
Two limited 2021-generation accounts differ on audible electrical noise; their cable regions are unknown. Check full-system load, the required GPU plug, appropriate original cables and room for a 160mm PSU plus cable bends.
An 850W and ATX label is not a complete fit check.
Conditions: One March 2021 Hardwareluxx investigation, explicitly CP-9020200-EU.
Meaning for your choice: Use relevant measurements for electrical assessment and check your connections.
Limits: No guarantee of every unit’s lifespan or noise.
Two self-reports explicitly identify a 2021 RM850x. One owner finds a small electrical noise distracting; another describes his own unit as barely audible.
Neither report confirms its cable region.
Assess noise in your PC and check the exact EU code and appropriate original cables. These accounts show different perceptions, not a defect rate or proof of electrical safety.
Limited 2021-generation context, not a separately established EU-owner sample. The RM850e opening post and cable-interchange advice are excluded. Electrical safety and causes of noise are not inferred from home accounts. Small self-selected sample of self-reported owners; purchases and accounts are not independently verified. Not a representative survey or a Specufo member score. · Checked 2026-10-29
Test configuration and limitsExternal voltage, ripple and noise testing of one exact EU sample in 2021. Not current retail stock, a modern GPU setup or a long-term failure test.
No Specufo hands-on test. Hardwareluxx examined the explicitly identified EU variant in 2021; different pages are one investigation, not additional samples. Owner context is available only at 2021-generation level.
Experiences form a limited model-level selection. Multiple posts from one owner, sponsored experiences and republications are not additional independent measurements. Region, RAM, firmware and test conditions can change outcomes.
Speed, battery runtime, camera quality and reliability require relevant evidence. Conflicting opinions are not averaged into a misleadingly precise score.
The source reading record distinguishes manufacturer facts, external tests and self-reported owner contexts. Test conditions and edition limits remain attached to the findings. This is not a Specufo lab test or member rating. Versions, software and use can differ; read the test limitations.
Match the shop listing to these details. A similar name does not prove the same configuration.
