Thermaltake Power Supplies

↪ Notes: Aggressive fan profile, ~40+ dbA output.

↪ Notes: Questionable fan quality, two EPS connectors on the same cable. Otherwise qualifies for A tier based on performance.

↪ Notes: OTP claimed; tested working in other GPR-based units in similar configurations.

↪ Notes: Excellent noise profile despite uncompetitive overall performance. Poor load regulation on the 5VSB rail and poor transient response on 3.3V.

↪ Notes: OPP works, OTP claimed; tested working in other GPR-based units in similar configurations.

↪ Notes: OCP is set much higher than necessary on all rails.

↪ Notes: Quite loud under full load, ~39dbA

↪ Notes: 5VSB OCP needs tuning (59mV ripple); An EPS cable can fit into a PCIe socket and vice versa, but they're not electrically compatible.

↪ Notes: Be wary of "2024 Version" 750/850W! Original is 160mm long, "2024" variant is 140mm long

↪ Notes:

↪ Notes: Semi-digital

↪ Notes: Europe, India and Japan model.

↪ Notes: Be wary of 2024 OEM/Platform change in the N.A. market!

↪ Notes: Be wary of 2024 OEM/Platform change in the N.A. market!

↪ Notes: Unnanounced OEM swap. Technically invalid 80 Plus certification, but did qualify for Gold in testing, as advertised.

↪ Notes: Single-sided PCB, voltage drops right before protection trip points on the minor rails; however, the protections did engage in time.

↪ Notes: OTP doesn't work

↪ Notes: OTP is set over 200C or doesn't work.

↪ Notes: Limited special edition model for 25th anniversary, no indication of any internal changes

↪ Notes: Very beefy platform, however OTP doesn't work; very loud. Would be tier A- if not for OTP not working.

↪ Notes: No MOV

↪ Notes: Costdown GX1 with 85C Chinese caps and a sleeve bearing Yate Loon fan; intended for OEM/SI market.

↪ Notes: Transient response was tested but values were left out. OPP is set very high, but the PSU handled it and shut down safely and properly.

↪ Notes: While a functional platform, the other two "known" 750W variants are unidentifiable.

↪ Notes: DC-DC, but 12V capacity is rated awfully low, at what a GR would typically be (672W or 56A).

↪ Notes: Poor thermal management; fan has to work very hard to prevent OTP from kicking in. Can get as loud as ~60dbA (!) under high operating temps.

↪ Notes: Be wary of 2024 CE-Link variant! GX1 costdown. If CWT based, 588W on 12V output for 600W.

↪ Notes: No proper transient testing, too old.

↪ Notes: OTP works on the 1200W model, however the 5VSB OCP is so out of tune, ripple suppression exceeds 100mV.

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

↪ Notes: Under crossload, 5V rail experiences high ripple >100mV, doubling ATX spec.

↪ Notes: Unknown number of suppliers. Missing crucial safety protections, very old platforms and very poor build quality.

↪ Notes: Very poor build quality and unknown number of suppliers, crucial protections not claimed.

↪ Notes: Black casing, white sticker. Unknown number of suppliers for this unit. Versions that have been tested have malfunctioning OCP, OPP, and SCP.

↪ 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: Malfunctioning protections that don't engage in time before the minor rails experience a huge voltage drop out of spec.
