Life Lessons on PSU's and Things I Learned the Hard Way - Yes, the PSU is Great for its Size
(Please forgive the quality of these photos, they were quick ones staging part of my home lab).I feel obligated after reading a couple of the reviews to throw my two cents in because this is great little PSU for its intended use case. First, I encourage you to always do your own independent research before buying a product, there are too many reviews/posts nowadays that are either bot generated from a competitor or written negatively when unfortunately someone perhaps didn't understand how the product fits into whatever they are working on.Let me start with Lian Li as a company, this is not so

Very nice!
So far, this is just want I wanted.The function test was perfect. CPU 24, CPU 4+4 good to go.Fan never kicked in, so I haven't evaluated the noise level.Haven't added all my drives or installed in a case yet, but I'll update this if I encounter any issues.Don't have an external GPU in this build, so those connections were not tested.Also have no need of the 12V 10-pin connection, so that was not evaluated.I noted a comment about cables being to long for one builder: Only the 4+4 cable seems longer than necessary, but the ribbon cable was easily folded and velcro or twist tied closed.

Brand new in Box, Dead
Power supply was DOA. I’m absolutely disappointed with Lian Li’s product quality. I have no idea how a power supply can leave the factory without being tested.Keep in mind that Amazon has been nothing but a headache processing this return. I ordered this item on August 11th, received it on August 12th, and sent it in on August 13th to be returned. I have spoken to three useless customer service agents who have promised the return to be credited back within 24 hours. And it is now August 26th. Still with no refund processed. I highly advise anyone purchasing any computer parts from Amazon to st

Great value for money and very quiet for SFF builds
The V1 of this unit was very loud and had some power delivery issues. V2 fixes that and it's very quiet even when the fan spins up which is very rare in my case. I'm running this in an SFF build with a Ryzen 5 5600 and Radeon RX 6700. Both are undervolted and tuned for lower power consumption, so the PSU fans never spin up.For the price, I don't think you can get anything better than this. Just be aware that if you're running power hungry components, it will run hot!

Make sure the item is compatible with the case you buy
It is a very nice PSU but the mini case I bought was specifically set up for the standard (not small) form factor so I had to return it and get a regular ATX PSU… I am sure it is a fine unit.
