Our verdict	Excellent performance and noise level at a mid-range price.	Unmatched efficiency and silence for the price of a high-end PSU.	Reliable, fully modular, and well-balanced for most users.	The Pure Power 13 M is a fully-modular, 850 W PSU that delivers 90 % Platinum efficiency and a 3-year warranty.	Corsair’s RM850e is a fully-modular, 850 W PSU that offers 90 % Platinum efficiency and excellent build quality.	PCIe 5.0 readiness gives it a future-proof edge over similar wattages.	Leadex V Platinum Pro is a 1000 W PSU that offers the highest efficiency (96 % Platinum) and the best price-performance for high-end builds.	Seasonic’s Focus GX-850 is a fully-modular, 850 W PSU that delivers 90 % Gold efficiency and excellent build quality.	The SFX benchmark with platinum efficiency and excellent support; small-form-factor buyers have no better long-term bet.	The MSI MAG A850GL is a fully-modular, 850 W PSU that supports PCIe 5.0 and delivers 90 % Gold efficiency.	Compact form factor is nice, yet it lags in noise and build quality compared to peers.	Good all-rounder but slightly behind the Corsair and MSI units in price/performance.	The Thermaltake Smart 700W is a budget PSU that only offers 80 % Bronze efficiency and has been criticized for noisy operation.	The Gigabyte GP-P750GM is a non-modular, 750 W PSU that offers only 80 % Bronze efficiency and has been noted for its noisy fan.	Corsair’s CV650 is a very low-cost, non-modular PSU that only delivers 80 % Bronze efficiency and lacks the build quality of higher tiers.

Where it falls short	Priced higher than some alternatives	High price Overkill for most builds	Priced slightly higher than some budget options Costs a little more than the MSI A-GL budget units	Nothing recorded	Shorter 7-year warranty versus 10-year rivals	Limited fan speed options	Retail presence and warranty service outside Asia are thinner than Seasonic, be quiet!, or Corsair	Nothing recorded	Nothing recorded	Component selection is a step below the flagships	Higher noise than larger units Build quality less robust Solid but not exceptional on the bench The SF750 does everything slightly better in the same niche	Not fully modular Only 80 % Gold efficiency Mixed reviews on build quality An aging platform	Only 80 % Bronze efficiency Noisy operation Outdated relic topology with entry-level protections PSU tier lists have placed it in their lowest acceptable or avoid tiers for years	Only 80 % Bronze efficiency Non-modular Noisy fan Center of a documented mass-failure scandal, with units failing catastrophically under load	Only 80 % Bronze efficiency Non-modular Poor build quality Group-regulated topology
