Plenty of juice to go around!
I use this in my main ITX build, it powers my rig quietly and efficiently, the cables and connections are of great quality and this is definitely a great piece of kit! Here's my setup: Cooler Master NR200p ITX case, i7-11700, 32 GB Corsair Vengeance RGB Pro, RX 6650 XT. It powers the heart of the rig and also all of my Case fans, upgraded CPU cooler! Definitely recommend for a solid, reliable PSU for your tiny build!

Very nice power supply
Nice, affordable powersupply. The fan is pretty silent, and everything works fine. The 24 pin connector cable could have been a couple of inches longer , but it worked fine for my setup

Quiet and effective
Replaced exact same PS - the first gave out after five years, possibly due to fine drywall dust getting in when doing some minor repairs. The new one works great and is much quieter. Hoping for a long life.

Great while it lasted. 4 months :(
I was pretty happy with this PSU while it lasted. Just a touch under 4 months and it shuts off unexpectedly after about 20-30 minute now. Only using half the power, PSU has built in Graphics so not much power. Very disappointed.

Good PSU, short cables
Good product, really compact and great recommend for itx build (even if the case supports ATX psu’s, because this has an adapter to save extra space). Be aware the cables are really short, so if you're Putting this in a Micro ATX case, you’ll need extension cables so they reach the motherboard.

Defective - no power!
I tested it with a multimeter and it refused to generate any power. Tried two different units, same result!

Faulty
Great till it's started to shut off every 20 minutes after 4 months of use. Tried every troubleshooting but came to a bad power supply.

Loud! Louder than all the other fans in my computer even when they run on full power.. for this price I wouldn’t normally care but they blatantly lied by saying it’s quiet..
