    The time has come to try out Lian Li's small power supply and I see that it has almost nothing to envy from its bigger siblings!
    Very nice finish and 'fabric' cables, although not all of them, only the pcie/cpu/mb (I wish they were all like that).
    It carries all the protections that a serious power supply should have, as well as 80+ gold certification. However, I would also like to see Cybenetics certification.
    The motherboard cable is a bit shorter compared to the others, but they did this to help with cable management in small cases (for which it is designed).
    One more complaint is that I would like it to have a third pcie cable and not just 2, one of which is pig tail, so it could provide a third connection to a graphics card.
    It also includes a cable-adapter to connect directly to a card with 12vhpwr, but you have to be careful where you plug it into the power supply, as the manufacturer recommends two specific ports.
    It is very quiet even under load, although its fan starts working when it exceeds 300w.
    It loses one star because it could improve some of the issues I mentioned above regarding the cables, and I would like two more years of warranty (from the 5 given to 7).
    Overall, I am very satisfied!

    This review is about the color: White

    I managed to get the white version for a white build in the Lian Li O11 Mini that was requested. The power supply was tested on a Z590-i with a 10900KF at 6.0 and a 3090, and even though it would be used in a machine with much lower requirements, it held up well and quite willingly. In games, the fan took a while to activate at 21:9 1440p, and when it did, it was overshadowed by the 3090 trying to cool itself, so I didn't expect it to be audible in a lower-end machine at all.
    In the final machine that was installed to stay (5930k on X99 with 980Ti), it simply fell asleep and we only heard that it exists when I ran a Cinebench after 9 months just to see if it was still working and hadn't burned out. Maybe there should have been a fan test button on all (gold and above) power supplies. All of its cables are sleeved and the connectors are also white. It lost the 5th star because it was available at that time for only 190€, which even now would be an expensive price. The price of around 140-150€ would be reasonable.
