User Experience

To thoroughly assess the GameMax GX Rampage 1050W power supply, we built a test system equipped with high-power components. This setup enabled us to push the PSU’s capabilities and observe its performance under substantial load, ensuring it could provide stable and adequate power to each component. Here’s an outline of the key parts used in our testing system configuration:

To assess the GameMax GX Rampage 1050W’s performance, we ran a comprehensive stress test using demanding tools such as FurMark for GPU load, ROG RealBench, Cinebench R23, and Prime95. Each test ran for at least an hour to ensure sustained stress across both GPU and CPU components. The maximum power draw recorded during this testing phase reached approximately 764 watts, using a GeForce RTX 4090 paired with an Intel Core i9-14900K, a high-power combination designed to push the PSU’s limits. Impressively, the PSU maintained stability without any issues throughout these intense sessions, demonstrating reliable performance under load.

Throughout the testing, the PSU temperature remained stable at around 52ºC, suggesting that the GX Rampage 1050W has substantial headroom beyond our peak draw. This stability under pressure is particularly valuable for users running demanding applications or gaming setups, as it indicates that the PSU can manage spikes in power requirements without sacrificing performance or safety.

Switching to gaming tests, the power draw stayed slightly below the stress test peak, but the GX Rampage 1050W continued to handle the workload effectively, operating quietly even during prolonged gameplay. The minimal fan noise can be attributed to the efficient 135mm Silent FDB Turbo Axial Fan, which cools the PSU without excessive sound output. This quiet operation makes the GX Rampage 1050W a great option for builders who value a low-noise environment while gaming or working, as the fan’s efficient design manages heat effectively without adding noticeable noise to the system.

First Impression

For budget-conscious gamers and builders, the GameMax GX Rampage 1050W stands out as an affordable yet reliable power supply, priced at $159 with an 80+ Platinum efficiency rating. Its 1050W capacity offers sufficient power for mid-range setups, as well as room for future upgrades, making it a practical option for those wanting a balance of performance and value. While higher-end PSUs offer superior efficiency and extra features, the GX Rampage 1050W holds its own as a dependable choice in this price range.

Interestingly, while the GameMax product page has yet to reflect the update, the GX Rampage 1050W is covered by a robust 10-year warranty—a competitive feature among 80+ Platinum-rated PSUs. This extended warranty adds value and peace of mind, especially for builders focused on longevity.

Overall, the GameMax GX Rampage 1050W delivers stable, quiet performance with adequate wattage and comes with a convenient accessory bundle. While it may not offer all the high-end features of premium models, it’s an attractive option for budget builders aiming to maximize performance without overspending.
