550W Power Supplies

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

↪ Notes: 650W is technically rated Cybenetics Silver

↪ Notes: Pro and Pro RGB Modular are the same internally.

↪ Notes: 1000W model might be DC-DC, unable to confirm without a proper teardown

↪ Notes: 1000W model might be DC-DC, unable to confirm without a proper teardown

↪ Notes: 1000W model might be DC-DC, unable to confirm without a proper teardown

↪ Notes: 1000W model might be DC-DC, unable to confirm without a proper teardown

↪ Notes: Overall very low build quality

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

↪ Notes: Updated M5+

↪ Notes: No transient response testing found.

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

↪ 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: 650W has poor 3.3V transient response

↪ 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: Not to be confused with the downgraded non-modular Pure Power 12!

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

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

↪ Notes: Looks exactly the same as the regular System Power 10 internally. Unless later testing proves the above issues are not present, detier to E.

↪ 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: "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: 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: White model available, same internals.

↪ Notes: "Semi-digital" - offers digital fan control and monitoring via MasterPlus software; actual components are analog.

↪ Notes: Platform is essentially a modified MWE Bronze V3.

↪ Notes: Basically G1208 updated to ATX 3.1

↪ Notes: Modified MWE Bronze V3, same as G Gold V2.

↪ Notes: Basically G1208 updated to ATX 3.1, no 12VHPWR.
