  • Is too much power a bad thing?
Style: TITAN GOLD Size: 1200W
My first PC build. Radeon Sapphire 7900XTX with AMD Ryzen 7 7800X3D in a Montech King 95. Aorus Waterforce 280 AIO and single 120mm fan, three Lian Li SL 120 V2 and three Lian Li reverse blade SL 120 V2. After watching videos and doing some research I determined that I could probably get away with 850w but the plan was to go with a 1000w PSU. Amazon happened to have this on sale for the same price so I went ahead and got it. This came with all the cables I needed, and some I didn't need to use. The GPU has all three 8 -pin slots filled. Everything seems to be running fine, though I'm not experienced enough to recognize issues that may result from lack of power. Last thing to note is that the cables are fairly rigid. I'm guessing the beefier cables are meant to accommodate the power it can dispense. ... show more

  • Tier A High-End PSU
Style: TITAN GOLD Size: 1000W
After looking on cultists.network for a PSU upgrade from my EVGA 450W Bronze Plus PSU, The Montech Titan 1000W was one that caught my attention and it has definitely been great for my upgraded build. Currently running Ryzen 5 3600 (soon upgrading to Ryzen 7 5700x3d), RX 6800, and 4x8GB 3200 MHz RAM. The Titan is able to provide all my components with more than enough power at quiet noise. The smart zero fan feature is nice to have and I don't ever hear the PSU ever ramping up. When turning on/off my PC, there is a noticeable click which is normal. Another thing I noticed unlike my EVGA PSU, is that when off, there will be no electricity going through the PSU at all which was nice when upgrading the rest of my components. I was able to get it for $99 before tax which was honestly a steal for this during the time since most 850W Gold Plus PSU sold around that price. ... show more

  • 1000w unit great quality super good price
Style: TITAN GOLD Size: 1000W
Upgraded from EVGA G3 750w. PC started OCP shutdowns while gaming after swapping 2080 Ti for a 3090. Problem solved now. I appreciate the minimal packaging, ATX 3.0 support, and high quality components. Competing unit manufacturers charging much more for equal performance.

  • Caused Shutdowns
Style: TITAN GOLD Size: 1000W
Upgraded my old PSU to get ready for GPU upgrade. Worked ok for the first couple of days. Then the random shutdowns every hour. It’s possible that I just got unlucky, but I won’t be trying montech again for PSUs. Even the cables felt a bit low quality compared to other brands I have tried. But that wouldn’t have been a big deal if it wasn’t causing my PC to lose power and cause shutdowns. ... show more

I bought a Montech case to go with the power supply and the two went together perfectly. After two weeks and several tests, I can't recommend this enough.
