Review: Very solid choice - This is a great PSU. It is a bit noisy if you are anal like me and others on this review page. If you'd like to void the warranty and put a quieter fan in this PSU my suggestion after trying the noctua route is to not use noctua (the fans people are recommending on this review page are not rated for this psu in terms of cooling efficiency and in my case the fan wouldn't even turn on unless I hooked it into my fan header on my motherboard even though its 12v in the psu and on the noctua fan. A more proper recommendation and expert advice would be to purchase Delta AFB0412HB 12V DC 0.16A Fan 40mm x 40mm x 15mm from ebay for 6 dollars. Be sure to check the polarity of the 2 pin/wire for this fan to ensure it matches the existing scheme/configuration. I believe its reversed but like I said, check for yourself. But Delta AFB0412HB 12V DC 0.16A Fan 40mm x 40mm x 15mm is a much better option than the Noctua. Don't waste your money on the noctua 40x10mm as not only is it too small and would require duct tape to cover the gap on the outside of the psu after its installed, its not even strong enough to push air in an efficient manner. Anyhow I wish you all good luck in your DIY this psu. For those not that are not ANAL like me, the noise is really not that bad. But I'll let you be the judge as I have tinnitus so I hear ringing in my ears anyway.
Review: Heavy - I don’t understand why flex is used instead of SFF PSUs when they weigh about the same but the SFF is actually smaller.

### ⭐⭐⭐⭐⭐ Solid affordable option
*by M***9 on February 20, 2025*

I used it to power an internal drive chasis outside of a Lenovo m720q running as a backup server with a wire jumper running between the atx-24 pins so that it would power on without being plugged into a motherboard. It was rock solid. Eventually I built a server and this fit the chasis for that so it is still running 24x7. I’ve had no issues so far.
