450W Power Supplies

↪ Notes: 650W is technically rated Cybenetics Silver

↪ Notes: Also known as CSK[w]H. Not printed on the logos.

↪ Notes: Mediocre transient response and low quality caps.

↪ Notes: Terrible ripple suppression, especially on 12V (well over 100mV under full load), OCP is not set properly, low efficiency, low quality fan.

↪ Notes: Design modified for multiple 12V rails: 3 on ≤550W, 4 on ≥650W

↪ Notes: Platform is somewhat mediocre, no direct transient response testing available and not the best choice of capacitors.

↪ Notes: "85% 230V only", ketchup and mustard cables. Outdated and no official 80+ certification, only on the tier list since it's still on their website.

↪ Notes: Identical internally to the MasterWatt Bronze. Only difference is the exterior appearance.

↪ Notes: Braided cables, some units manufactured between Oct. 2019 to Mar. 2020 (lot codes 194448xx to 201148xx) recalled for potential failures.

↪ Notes: Standard cables

↪ Notes: Black "CX" lettering on gray label; Double-sourced between GW & CWT; technically qualified for 80+ Silver but badged as Bronze.

↪ Notes: Black "CX" lettering on gray label; Double-sourced between GW & CWT; technically qualified for 80+ Silver but badged as Bronze.

↪ Notes: Grey label

↪ Notes: Grey label; OCP doesn't work properly, allowing the voltages to fall out of spec, very poor ripple suppression on 5V, failed transient testing on 3.3V

↪ Notes: Internals appear to be variable based on region/batch.

↪ Notes: Net graded to Tier E due to it being group regulated.

↪ Notes: Single EPS cable. Great electrical performance but OTP is not claimed.

↪ Notes: Decent overall performance despite being ACRF on the primary side, double ball bearing fan.

↪ Notes: No OCP on 12V. High RMA rate due to MLCC cracks, similar to other HEC-built EVGA PSUs

↪ Notes: OCP on 12V doesnt exist. OPP is set too high. Sleeve bearing fan.

↪ Notes: Platform is an old Super Flower design, but is actually produced by RSY.

↪ Notes: Doesn't claim necessary protections. No real 80+ certification label on the unit.

↪ Notes: Actual +12V capacity is ~5-10% lower than advertised wattage.

↪ Notes: Either dual sourced or XWY replaced HKC.

↪ Notes: Either dual sourced or XWY replaced HKC.

↪ Notes: Terrible electrical performance under crossloads (effect of Group Regulation), and overall poor performance otherwise.

↪ Notes: Low quality sleeve bearing fan, ripple exceeds ATX specification, low quality capacitors, and a 3 year warranty.

↪ Notes: Some units produced before 2018 may experience shutdowns with high transient draw GPUs.

↪ Notes: SFX-L

↪ Notes: EU/JP only? No stated manufacturer warranty outside of mandated EU 2 year warranty.

↪ Notes: Fanless

↪ Notes: No OTP and OCP (12V) present; low hold-up time (out of spec); poor soldering quality.

↪ Notes: 3 separate versions dependent upon region, most groupreg. Also a 230V only version. Essentially unrecommendable due to platform variation.

↪ Notes: Multiple inexcusable protections malfunctions despite good electrical performance.

↪ Notes: Missing crucial safety protections, very old platform and very poor build quality.

↪ Notes: Over 500mV of ripple at 110% load on the +12V line is inexcusable (over 4x the ATX specification limit). Clearly a major design flaw.

↪ Notes: Poor electrical performance from an unknown OEM; fails all 12V transient response testing per F14 Lab's testing.

↪ Notes: Claims to be DC-DC, but internal shots show otherwise; false advertising.
