  • GREAT PS - size is awesome, plenty of power
Style: LOKI|SFX Size: 1200W|Black
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. ... show more

  • A work of art!
Style: LOKI|SFX Size: 1200W|Black
Such a work of art! Such beauty! It is running my Asus CROSSHAIR X870E - Asus ROG Astral OC BTF, Custom water loop for the CPU blissfully, the main reason why I choose this was to be able to use the Corsair air 5400 & the Bitspower AMD Revo Block, standard PSU will not work if your using that Water Block in this case, Took the idea and concept from GGF Events on YouTube. You will need a SFX/L PSU or you will have to modify the Corsair 5400. Overall I’m impressed and glad it’s not a DOA like others experienced. ... show more

  • Fantastic small size PSU.

Fantastic PSU if you need to use a high end PSU in a smaller case.

  • Good but concerned about longevity
Style: LOKI|SFX Size: 1200W|Black
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 temperature isn't enough unless you have AC) ... show more

  • Highly recomended
Style: LOKI|SFX Size: 1200W|Black
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 on off brand power supplies, this one really give you your money's worth for its performance. ... show more

This thing is a beast. Looks great and has plenty of power. It is more then my machine needed. The fan only kicks on when needed. RGB looks great through the side of my case. the small form factor would fit any size case. highly recommended

  • Solid PSU, the one to get for future proofing
Style: LOKI|SFX Size: 1200W|Black
I decided to downsize my build to a ITX build since I use external cooling (Mora 420) - I have this PSU in a Ncase M2 Grater, powering a 14900k overclock & and 5090 Founder Edition. I did notice the PSU gets pretty hot under heavy loads but assume its within normal operating conditions. PSU has been rock solid and its is nice to have the new ATX 3.1 standard along with (2) 600W PCI connectors for future use. 10 year warranty keeps my mind at ease. Great quality factory cables as well that are easy to maneuver in tight spaces. Titanium rated is a huge win in the form factory as well since I came from a EVGA 1600T2. Highly recommended! ... show more
