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: Runs a 5090 without spending a fortune. Seasonic quality. - As expected from Seasonic it works perfectly and has plenty of cables. The were nice enough to send me the updated power cable for my 5090 for the cost of shipping despite being past the 90 day cutoff from day of purchase. It hasn't melted yet after a couple months of gaming. Power supply is quiet and I don't notice it. As it should be.

### ⭐⭐⭐⭐⭐ Great Power Supply
*by S***0 on April 3, 2024*

This is a great power supply for 1200W but it was a steep price. I want with another brand and after about two weeks that power supply went out so I decided to go with this brand since it been around for awhile and is a manufacturer of power supplies for other companies also. It still going strong over two or three months without any issues. I bought two of these, 1 for my son and the other for my computer and they both worked well. I would recommend buying these if your machines need 1200W or less power. This also comes with the 600W power supply cable and is the new standard for the Nvidia 40 cards. The only thing I would do differently is buy the gold version of this as there is that big of a difference between gold and platinum efficiency ratings.
