Corsair RM1200e Power Supply Review
Conclusion
2026’s RM1200e is a big upgrade over its predecessor
Releasing a new PSU with the same name as an older model isn’t new for Corsair. While an older PSU called the RM1200e exists, it doesn’t have much in common with this new model. For starters, we’re reviewing the PSU’s white model today. The old version didn’t have a white model. Additionally, the original didn’t ship with a native 12V-2×6 power connector.
This new model doesn’t just give the RM1200e a facelift and refreshed electronics; it feels like a fundamentally different product. Its debossed cables make it feel more premium than its predecessor, and then there are hidden changes like Corsair PinProtect
This doesn’t feel like a model refresh; it feels like a step up
The killer feature that the new Corsair RM1200e offers is PinProtect. It’s per-pin overcurrent protection for 12V-2×6 power cables. This feature prevents potential 12V-2×6 cable melting incidents by cutting power to your graphics card if excessive current flows through any power pin for an extended period. This prevents damage by cutting power before heat builds up and connectors burn. This feature is built into the new RM1200e and requires no software or configuration to use.
With its new enclosure, updated electronics, new features, and debossed cables, the new RM1200e doesn’t feel like a refresh; it feels like an upgrade. Yes, it targets the same efficiency levels as before, but it offers users a more premium aesthetic alongside valuable new features. If you worry about potential 12V-2×6 cable melting incidents, Corsair’s PinProtect feature is a valuable add-on. This puts the new RM1200e ahead of most competing PSUs, since few on the market offer the peace of mind PinProtect delivers.
The new RM1200e is an efficient PSU that delivers strong ripple performance and valuable features at £169.99. It’s not the most efficient PSU out there, but it’s also not the most expensive. Climbing the PSU efficiency ladder can get expensive quickly, and this PSU delivers solid value for your money. This PSU isn’t just a refreshed RM1200e; it’s a better RM1200e.
