Kolink Continuum KL-C1500PL PSU review – one for miners!

Kolink are using a 135mm Yate Loon double ball bearing fan inside (Model: D14BH-12). It is rated 1V 0.70A. We have seen this fan in some other power supplies in recent years, including the Corsair AX1200. It can get quite loud under load but has been chosen for long life characteristics due to the target demographic (predominately miners).

The Fan is controlled by a digital circuit (MCU) due to the fact that analog fan control has proved to be a problem for some designs. MCU also allows for better Hysteresis and refined precision. These are inherently louder fans so they clearly don't want to exacerbate the issue further with sloppy fan curves.

We can see from the images above that the OEM partner is Enhance. An OEM I rate quite highly when they decide to make a higher end unit. They are also known to be quite cost effective and this Kolink KL-C1500PL supply is one of the cheaper 1500watt Platinum units on the market.

Soldering quality on the main PCB and daughtercard is overall very good. There are a couple of large overhead style heatsinks to ensure there is plenty of cooling capability inside the unit. The cooling fan situated directly above should ensure they run cool.

This particular unit looks quite familiar to the other 1500W Enhance units I have seen based on the newer LLC Primary and DC-DC secondary implementation. When I spoke with Kolink about the design they said they made 50 changes to the regular Enhance models to improve performance and fix minor concerns. This is a design unique to Kolink right now.

The primary stage features three high grade 105c Japanese Nichicon capacitors rated 450v at 560uF per capacitor. This gives a total output of 1680uF. This really is immense!

Protective Circuits:

• OVP/UVP (over- and undervoltage protection).
• SCP (short-circuit).
• OPP (overload).
• OCP (overcurrent on the rails +12, +3,3 and +5 Volt).
• OTP (overheating protection.
