lucky1 Posted December 7, 2007 Posted December 7, 2007 I'm looking at purchasing a Corsair 620W PSU. Unfortunately, I recently became aware that there may be an issue with this PSU and the NF4 Ultra-D because it is manufactured by Seasonic. Was the Seasonic DFI compatibility issue fixed? Are Corsair 620W PSU affected? If yes, has this been corrected in any product revisions? Thanks Quote Share this post Link to post Share on other sites More sharing options...
Guest element Posted December 7, 2007 Posted December 7, 2007 I used an early model HX620 with my Ultra-D. Thus as far as I am concerned it was fine. Not a huge load as I only had modest hardware back then. Nevertheless it was a rock solid unit. Quote Share this post Link to post Share on other sites More sharing options...
Sharp Posted December 7, 2007 Posted December 7, 2007 The issue was fixed (new revision A3) quite a while ago and does not involve the Corsair PSUs. Quote Share this post Link to post Share on other sites More sharing options...
lucky1 Posted December 8, 2007 Posted December 8, 2007 The issue was fixed (new revision A3) quite a while ago and does not involve the Corsair PSUs. The information from the last few pages of the Seasonic incompatibility thread contained some conflicting information. There were a few posts suggesting that the issue would be fixed in a 3rd revision. However, a page or two later there was an official response from Seasonic posted that more or less refused to acknowledge any problem, nor was any statement made about a fix. The reason I posted this question was due to a conversation I had with a member of Corsair's tech support a few days ago. The support tech more or less conveyed that the 620HX would not work with the Ultra-D motherboard, even though the NF4 Ultra-D was compliant with ATX 2.01 and that they'd had some issues with that board. I figured I would post here to try and receive some clarification since I'd seen a few people with the DFI NF4 Ultra-D and Corsair 620HX configuration.

Guest element Posted December 9, 2007 Posted December 9, 2007 Good Idea perhaps you should PM the corsair rep ( yellowbeard AFAIK?) Quote Share this post Link to post Share on other sites More sharing options...
Yellowbeard Posted December 9, 2007 Posted December 9, 2007 Actually, I would go with what our Tech Support guys said. They have access to the PSU info that I don't. DFI 939 boards predated my time at Corsair so those guys are the best source of info. Quote Share this post Link to post Share on other sites More sharing options...
AMDZen Posted December 11, 2007 Posted December 11, 2007 What kind of problems are we discussing? I use an S-12 A02 and I have no issues at all. I also have a corsair 620HX so I can try that and I'll let you know if that one has any issues, but I can't imagine it would. Let me know what I would be looking for Quote Share this post Link to post Share on other sites More sharing options...
larrybody Posted December 12, 2007 Posted December 12, 2007 I have both the HX620 and the HX520 units. Replaced the failed Antec unit in my Nf4 Ultra-D with the HX520 almost a year ago and it dosen't miss a beat. Liked it so much I used a HX620 for my Core2 e6600/8800GTS build last June. The quality is evident as soon as you open the box. This is the first I have heard about any incompatability issues. Quote Share this post Link to post Share on other sites More sharing options...
AMDZen Posted December 12, 2007 Posted December 12, 2007 OK well as my sig says (it might have changed because I'm going to go change it after this post) I had (until last night) a Seasonic S12-600w rev. A02 PSU installed on my system. Never had an issue. I recently purchased a Corsair 620HX from eBay for 100$ and the Antec Nine Hundred Case. I transfered my current rig into the Nine Hundred and also installed the 620HX. I am going to put the Seasonic in my rig downstairs as it needed a PSU upgrade (my other rig is an HTPC with 7 HDD's and only had 430 watts) and I also wanted a quieter PSU in the HTPC. Any way, I just transferred all my components last night but so far I have had zero issues. I wouldn't hesitate for a minute to purchase one of these baby's - they are sweet. I lose the plug configuration a la antec PSU's but its Seasonic so boy is this thing quiet and efficient. Best all around PSU's on the market EDIT: OK my sig holds both my machines, but I have used both the S12 and now the 620HX without issue on my DFI MoBo Quote Share this post Link to post Share on other sites More sharing options...
lucky1 Posted December 29, 2007 Posted December 29, 2007 Just to update thread... After some discussion with Angry, I went ahead and took the plunge on a Corsair 620HX. Installed the unit in the second week of December in combination with a DFI NF4 Ultra-D. No stability issues have been encountered that can be attributed with the Corsair unit in this build configuration. Sig updated...
