Chieftec/Chieftronic Power Supplies

↪ Notes: Good build and component quality, with good ripple suppression and a decent noise profile. Notably, Aris received a PPG-C sample with a higher capacitance bulk capacitor, different from what other reviews had. PPG-C and PPG-S are identical aside from modularity.

↪ Notes: Platform is well reviewed although no direct transient response data.

↪ Notes: Semi-digital

↪ 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: Decent electrical performance but OTP is either not present or set too high (>200°C ) which is useless. See testing here. 2 year warranty.

↪ Notes: Fundamentally a Polaris ATX 3.0 refresh. Load regulation is somewhat subpar on the 1050W model.

↪ Notes: Sleeve bearing fan, during OPP testing at around 30% of the 500W model do the minor rail falls out of ATX specification.

↪ 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: 3 year warranty; 85C bulk cap, and not one of particularly good quality, either.

↪ Notes: 3 year warranty; 85C bulk cap, and not one of particularly good quality, either.

↪ Notes: OPP is functional but offers only a 7% increase over the nominal value, beyond which the rails fall out of ATX spec for the 1000W model.

↪ Notes: Voltage regulation is out of ATX specifications on the minor rails; also not independently regulated.

↪ 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 Outdated and no official 80+ certification, only on the tier list since it's still on their website.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: "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 Outdated and no official 80+ certification, only on the tier list since it's still on their website.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 Outdated and no official 80+ certification, only on the tier list since it's still on their website.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: Only basic voltage regulation and ripple data found here. Not recommendable due to age; only kept for legacy purposes (still on website.)

↪ Notes: Yellow on black label; no 80+ certification and aging. Not certain on topology but not recommendable regardless. See review here. No OCP.

↪ Notes: Blue label. No OCP.

↪ Notes: Doesn't claim OCP.

↪ Notes: "85% 230V only", ketchup and mustard cables, not independently regulated. Doesn't have OCP according to this review.

↪ Notes: Fake 80+ 230V only certification label, ketchup and mustard cables, not independently regulated. White label. No OCP.

↪ Notes: Fake 85% efficiency label, black on yellow label; it's also old. Not certain on topology but not recommendable regardless. See review here. No OCP.

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