So far so good. Running my 7800x3d and 9070xt no sweat. Just power housing. Got power room for later upgrades whenever next generation graphics cards come out. The individual sleeving IS a bit of a pain in the ass HOWEVER.... it also makes routing cables in a very tight case stupid simple. I could care less about RGB lmao. I dont go for looks I go for performance. And its whisper quiet for me so.... no issues.

This thing is amazing. Installed in a Lian Li B4-mATX case which had to be slightly modified to fit this on the SFX bracket but definitely worth it. Running a 14th gen i9 CPU, RTX5090 GPU with 3x M.2, 9 fans and full custom liquid loop. So far no issues under load but will update if a power spike causes shut down
This power supply is so small and quiet. It was quite smaller that i thought it would be. It has been running in my new build with a power-hungry AMD 9950X processor, AMD 7900 XT graphics cars, 7 fans with LED, 64 GB RAM with LED, thousands of more LED's everywhere else, two small internal screens powered by the power supply, a crap top of accessories. I am pushing it as much as I can. I use high intensity photoshop files, play all types of heavy games, and i never been able to over power it. I been runnig it since September 2024, so far no issues. Very easy to install. Do not waste your money
2nd one I have purchased - first was the 1000watt for other ITX mobo build, this was the 1200 watt for new compact ATX build in Mechanic Master C34 Pro case... worked like a charm... super quiet... plenty of power and size is great since I wanted to build a compact system. These are awesome. PC is in case below just behind the LONG Graphic card, would not fit a standard ATX PS... but this SFX was a dream fit and extra room when done.
Excellent quality PSU BUT it does NOT have nearly enough cable ports on it to supply most gaming motherboards(Which use two Motherboard cables to fuel the board). It only has a port for ONE single motherboard and ONE single GPU cable that's all and No Sata. I'm glad this was the wrong PSU for my case because now I actually have something to return it for. Crazy how they limit what you can power with a 1200 watt PSU Like you can't even come close to utilizing that amount of power with only one mobo and one GPU cable... No way.
Powering my 9959X3D & 5090 just fine 👌
Cables are nice and soft. Braided but bends easily. Replaced the old evga 1000p2. Slats over the fan are interesting. Not preferred but well machined. Hefty PSU for its size. Go small and don't have to worry about changing cases. Noise, Can't hear it anyways.
Using this in a system that has 3x nvmes, 9800x3d, 32gb ddr5, and rtx 5090. The unit was placed outside the case to test for any shorts with the liquid metal i used for the cpu. While the PSU fan didn't spin up right away - that kind of caused it to get super hot to the touch once I powered down after playing for about an hour and a half. I didn't have the tools to measure the psu's temperature, but it must've been high enough to almost burn me. This might be normal for a psu so I'm not sure, but definitely don't touch it after intensive use and make sure you have fans to cool it. (Ambient air
