Review: Great High Quality ATX 3.1 PSU (2026 Update) - UPDATE: When I originally ordered this PSU it was ATX 3.0 and my unit had some issues with mild coil whine even after a replacement. I switched to an NZXT C1500 and sold the original PSU to a friend. I had originally given the PSU a 4-star rating. I just changed my PC case to downsize my build foot print as such while the NZXT C1500 fit it was the maximum possible PSU length and I couldn’t reinstall the cable/SSD cover and so I decided to reordered this PSU. I was pleasantly surprised to see that its been refreshed and it’s now an ATX 3.1 with a 12VHPWR 2x6 it’s got a really distinct blue head on the connector now which will easily tell you if it’s fully seated hopefully mitigating any issues or potential fire hazards. Another new surprise is that now Seasonic includes cable combs for your PSU cables. I always thought this was a strange omission since they made such a big deal about the individually sleeved cables. This makes the cables look much cleaner in my build and overall elevates the PSU compared to before. The last and nicest surprise for me is that at idle or under load my PSU is nearly slient. I can’t hear any coil whine and it’s only audible via the fan when my ear is directly next to the case where the PSU is. This is excellent and now the only coil whine I hear in my build is rather obnoxiously from my 4090 FE. Overall this is great revision to an already excellent PSU. My only real gripe is the price. There are plenty of other PSUs in this spec at lower price points. That said Seasonic is well known for their reliability and honoring their lengthy 12 year warranties without fail. New rating for the ATX 3.1 variant is 5-stars.
Review: Exactly what you get and well worth it! - Runs great. Fantastic warranty. Comes with all you need just can’t fit in place of a tiny PS. It’s full size. Great price especially with a Longer than average warranty. If you have a newer case ( not like smaller Dell or such it takes almost no time to install. Even comes with the new 12pin connector for the latest and greatest GPU. As far as heat, far less of a problem than cheaper power supply’s. I run Server with 7 drives and dual Xeon processors. Heat has not been a problem for me. Runs warm but considering it’s 1200watts, it’s average on the cooler side.
