650W Power Supplies

↪ Notes: 5 year warranty, OCP is set way higher than necessary on the minor rails.

↪ Notes: Though a sleeve bearing fan is used, 1st Player backs it up with a 7-year warranty.

↪ Notes: OCP is not claimed on any rail (although it most likely exists for the minor rails only), very low +12V line output relative to total capacity.

↪ Notes: Costdown Core Reactor II

↪ Notes: ATX 3.0 refresh

↪ Notes: Despite markings on the DC-DC daughterboard indicating CWT GPU, internal shots confirm CWT GPX.

↪ Notes: Decent electrical performance, although some components are of questionable quality.

↪ Notes: 650W is technically rated Cybenetics Silver

↪ Notes: No OTP claimed

↪ Notes: No OTP claimed

↪ Notes: Overall very low build quality

↪ Notes: Double-sourced between HEC and Andyson

↪ Notes: Double-sourced between HEC and Andyson

↪ Notes: Claims APFC, "90+" badge, extremely low 12V output relative to total, as is per usual for terrible PSUs

↪ Notes: Improperly set OCP allows for abysmal voltage drops past ATX spec.

↪ Notes: No transient response testing found.

↪ Notes: Cost-down SSR-FM platform. White 750W is available.

↪ Notes: 2 850W samples died in testing during OPP/OCP evaluation.

↪ Notes: Appears to be targeted primarily at the Eastern market.

↪ Notes: DC-DC variant of the CSK Bronze; only 750W has 300W 12VHPWR.

↪ Notes: No inrush protection. Sold in the US as Earthwatts Green. 650W utilizes 105C secondary caps, 550W 85C.

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

↪ Notes: Most likely for the Asian market; sightings in China and India. Ketchup and mustard cables, different fan grille, label, and box.

↪ Notes: X8 might be a clone of CWT's GPK platform, but is similar to the M5 platform (not very good.)

↪ Notes: X8 might be a clone of CWT's GPK platform, but is similar to the M5 platform (not very good.)

↪ Notes: PPFC; e-waste

↪ Notes: 1000W model has poor transient response on 12V under 200% spike, other models mediocre. 850/1000W avail. in white.

↪ Notes: No 12V-2x6; only one 8-pin PCIe connector.

↪ Notes: No 12V-2x6; only one 8-pin PCIe connector.

↪ Notes: Ball bearing fan, 8 year warranty. Cybenetics Gold under 120VAC and Platinum under 230VAC.

↪ Notes: 2 year warranty. PSAZ Bronze w/ARGB fan. 540W, 648W, & 744W on 12V respectively.

↪ Notes: Cost-down full input new PSAZ Bronze w/ ARGB fan.

↪ Notes: 2 year warranty. 550W: 540W on 12V, 650W: 648W on 12V, 750W: 744W on 12V.

↪ Notes: Cost-down full input new PSAZ Bronze.

↪ Notes: 2 year warranty. PSAZ Bronze w/ARGB fan. 550W: 492W, 650W: 576W on 12V.

↪ Notes: 2 year warranty. 650W: 576W on 12v.

↪ Notes: 85C bulk caps, excellent noise profile.

↪ Notes: Low quality fan, 85C bulk cap.

↪ Notes: A few samples of the base platform died when subjected to sub-90VAC stress tests per JonnyGuru. Proceed with caution under 120VAC, especially in areas prone to brownouts.

↪ Notes: Both EPS connectors share a cable, poor regulation and transient response on minor rails; only a 2 year warranty.

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

↪ Notes: "90% 230V only", claims meeting 80+ Gold without certifying. No direct transient response testing but platform is well reviewed.

↪ Notes: Receives a "-" subtier due to its age. Only kept for legacy purposes as it is still listed on Chieftec's website.

↪ 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: Electrical performance is decent (although no transient response data) but simply not recommendable due to age.

↪ 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: Protections don't kick in nearly in time before the voltage on the minor rails falls out of spec under ~108% overload.
