Epilogue
The RM750e unit’s overall performance is notably lower than the new RM750x, which is the point here since the RMe line is below the RMx one. If you want my expert opinion, Corsair’s RMx line is among the best in today’s market, so if you want a PSU for the next 5-10 years, I suggest you don’t think of the extra cost and get an RMx ATX v3.1 PSU since besides increased performance you will also get low noise output and increased reliability. But since this review is for the RM750e, I must also devote some lines about it. I cannot say that the RM750e impressed me enough. It offers ATX v3.1 compatibility, is silent, and delivers full power without issues, even at high temperatures. Still, ripple suppression could be better at high loads, and the same goes for transient response in general, while the load regulation might be within 1% on all rails, but still it isn’t that extra-tight. The protection features, OCP at 12V and OPP, also need adjustments to have a longer gap between normal and high temperatures. Typically, a PSU is stressed way more under high temperatures, so it only makes sense to have lower OCP and OPP triggering points under stressful conditions than normal operating (temperature) conditions.
For those concerned about NVIDIA’s new RTX 5070 and 5070 Ti graphics cards, if you don’t go wild with the processor (CPU) and its operation profile, the RM750e (ATX v3.1) will handle them just fine. But you should always consider the CPU’s power consumption because, for example, an Intel Core Ultra 9 Processor 285 has close to 450W sustained power consumption with an Extreme Performance profile applied!
