Kolink Classic Power 400W Power Supply Review - What do you get with €40?

💥 Model number: Kolink Classic 400W 💥 OEM: Casecom 💥 Members on this line: Four, 400 - 700W. 230V input only. 💥 Efficiency: 80 PLUS Bronze, Cybenetics Silver (87%–89%) 💥 Noise: Cybenetics A (20–25 dBA) 💥 Modular: No 💥 Dimensions: Compact (140mm depth) 💥 Price: €40 💥 Warranty: 3-years 💥 Power Specifications: Single +12V rail 💥 Power Distribution: 348W at +12V, 80W on the minor rails, 350W Max continuous power, 400W peak. 💥 Cables: 1x EPS, 1x PCIe, 3x SATA, 2x 4-pin Molex 💥 Cable Length & distance between them: Long enough cables with only 100mm distance between peripheral connectors 💥 In Cable caps: No 💥 Internal Design / Build Quality: Double forward topology on the primary side and synchronous rectification on the secondary side. Pair of DC-DC converters for the generation of the minor rails. 💥 Caps and Fan manufacturers: The filtering caps are by AsiaX. The sleeve bearing fan is by Alpine, a brand not that well known but quite large. 💥 High-Temperature tests: This PSU doesn't struggle with 350 W at almost 35 °C ambient. Applied up to 385 W at 37 °C. 💥 Fan Speed profile at high Temperatures: Not that aggressive. 💥 Load Regulation: Load regulation is tight on all major rails. 💥 Ripple Suppression: Ripple suppression is excellent at 12 V, 5 V, and 5VSB, and satisfactory at 3.3 V. 💥 Transient Response: Mediocre on all rails but 3.3 V, where it is terrible. 💥 Hold-up time: Hold-up time is not that far removed from 17 ms. The power ok signal is accurate. 💥 Inrush Current: High with 230 V input. 💥 Protection Features: OCP at +12 V is reasonably set, and the same goes for the 5 V rail. OCP at 3.3 V is set quite high for no good reason. OPP is higher than 130%. You should not make the PSU exceed its maximum rated power output for prolonged periods of time, however. Even though essential in a PSU, there is, no over-temperature protection, and this platform lacks surge protection as well. 💥 Conducted EMI Emissions: They are low. The EMI filter does a very good job. 💥 Average Efficiency: High, reaching an average score of 88.23% with 230V input 💥 Average PF: It is not so high, but not bottom low either. 💥 Average Noise Output: This is a very silent power supply, especially if we take into account its price range and efficiency. 💥 Overall Performance: It does very well, scoring between the XPG Pylon 450 and the Cooler Master MWE Bronze 500. 💥 💥 💥 Bottom Line 💥 💥 💥 All in all, this is a fine PSU. That said, if I could make any changes, I would use better caps on the secondary side, a higher-quality fan, properly set protection features, the addition of OTP and surge protection (an MOV), and either a correction to 350 W in its advertised power output or better parts that allow it to actually handle 400 W continuously. All these changes would make it slightly more expensive, which users in need of a mainstream power supply won't like. That said, If you want to spend a bit more and need something that can deliver more juice, you should take a look at the Corsair CX450 or XPG Pylon 450. Pros 👍 • Very affordable • Quite a capable platform for its price • High overall performance • Efficient platform for the price • Silent operation • Tight load regulation • Very good ripple suppression at +12 V • Low conducted EMI emissions • Flat, black cables (not modular) • Cables are quite long • Compact dimensions Cons 👎 • Marketing advertises this PSU as 400 W even though its continuous maximum power output is 350 W • No MOV in the transient filter • No OTP, and OCP/OPP triggering points are not correctly set • Mediocre transient response (especially at 3.3 V) • PF not that high • Sleeve bearing fan and low-quality filtering caps on the secondary side • Hold-up time below 17 ms • High inrush current • No modular cables, and the AC power cord has not been included #HardwareBustersInternational #Kolink #ClassicPower 💘 If you find our content helpful, please subscribe to our channel. https://www.youtube.com/HardwareBuste... 🔔 If you enjoyed this video and you want to help others to enjoy it as well, please support us by adding captions in your native language https://www.youtube.com/timedtext_vid... 🏁 Share this video with your friends:    • Kolink Classic Power 400W Power Supply Rev...   📢 Follow us on social media: Facebook:   / hardwarebusters   Instagram & Twitter: @hardwarebusters 00:00 – Intro 00:11- Product Presentation & Main Characteristics 01:04 – Power Specifications 01:44 – Cables 02:16 – Internal Design & Build Quality 03:09 – Caps’ & Fan Manufacturers 03:43 – High-Temperature Tests 04:12 – Fan Speed Profile 04:18 – Load Regulation 04:26 – Ripple Suppression 04:36 – Transient Response 04:48 – Hold Up Time & Power Ok Signal 04:59 – Inrush Current 05:09 – Protection Features 05:56 – Conducted EMI Emissions 06:03 – Average Efficiency 06:13 – Average PF 06:18 – Average Noise Output 06:27 – Overall Performance 09:21 – Alternative Suggestions 09:55 – Pros 10:26 – Cons
