The new Intel specification requires better efficiency at 2%-10% load and new timings (T1 and T3 to support modern standby mode). This was not easy/cheap to achieve, so Corsair couldn't just replace the current RMx in the market with a new, more expensive version without tangible differences. So the capacitors and fan was "down graded" (though Hong Hua is a fantastic fan manufacturer) to allow this "new version" of the RM to meet an acceptable price point. The review here just made this unit be one of my recommended 650 models, tied with the EVGA G2/P2 and just below the Seasonic 660XP2! Seraph (Laptop 2) CPU: i7 6700HQ GPU: GTX 970M 3GB RAM: 2x8GB DDR4 Storage: 256GB Samsung 951 + 1TB Toshiba HDD Model: Asus GL502VT Yeah, I believe you are confusing the RMx and RMi with the older, mostly discontinued RM line. And of the old RM line only the 750w and 850w versions that were first made by Chicony Power Technology had the bad reputation. Anyone bashing the RMx and RMi doesn't know what they are talking about. Once misinformation gets out there it's hard to get it corrected though.
Only info I found online was quite a few people saying to "avoid the RM750 as it's a "Tier 3" psu... Whatever that means... They are both Gold rated?? OVP (Over Voltage) | UVP (Under Voltage) | SCP (Short Circuit) | OTP (Over Temp) | OPP (Over Power) This is a quiet PSU. The difference between it and the 650 P2 is so small as to be imperceptible. Efficiency Rating
Completely modular cables means you only connect the cables your system needs, and the wide range of included cables adds broad compatibility with modern graphics cards and motherboards. The 5VSB rail is highly efficient, losing only to FSP's HG650 and its advanced 5VSB circuit. Power Consumption In Idle And Standby DC-DC Converters: 2x UBIQ QM3054M6 (30V, 61A @ 100°C, 4.8mOhm) & 2x UBIQ QN3107M6N (30V, 70A @ 100°C, 2.6mOhm) PWM Controllers: uPI SEMI uP3861P The RM650x easily meets the ErP Lot 6 2013 directive's requirements.

Primary side: Half-Bridge & LLC Resonant Converter Secondary side: Synchronous Rectification & DC-DC convertersFun fact: Removing the caps from the cables saved A LOT of money. As you can see, it didn't have much impact. The caps in the cables in other models are only there to appease reviewers (like Aris) that compare ripple from one model to the next within mV of each other. Unfortunately, we didn't test the EVGA 650 G2 with 115VAC input, so we can only compare the RM650x to EVGA's 650 P2. As you can see, the performance difference is notable. Then again, the 650 P2 is a Platinum-rated PSU while the RM650x only satisfies the 80 PLUS Gold standard. We should also note that with 230V input, for which we have test data for the 650 G2, the RM650x clearly leads with a 3.54% difference (EVGA 650 G2: 96.46%, Corsair RM650x: 100%).
