This power supply, unfortunately did not work for me. I bought it for my new build pc last week, around first of July, at CompUsa. First off, it would run fine, when I first turned my pc on for the first time. However, it would shut off randomly, after sometime of use. So, I downloaded latest bios(1205) for the asus board. That seemed to solve the random shut off. Once pc was together, everything was smooth and working great.
Did 3dmark 06 test twice. Worked like a champ. No problems so far. Did stress testing with prime95. Computer shut off about 30 minutes into test. Also, same thing with memtest86. Would run about 30 minutes and shut off. The only clue I had was the log file from prime95. It did not show any errors from stress test. This lead me to believe that the psu could be the problem, since the computer would shut off, around the same amount of time of stress testing. I put in my older TPII 480W antec and all problems were solved. Stress test ran all night with prime95. As a side note, when using the neohe 550, I saw that one of my dual cores processors was sporadic in task manager. It didn't keep at full 100%. However, with TPII 480, both cores were full 100% with little fluctuation in task manager. The neohe 550 just didn't supply clean power to my system. It was fluctuating too much. Even though my multimeter showed everything was peachy within +-3%, the power supply was not cutting it. Weird. I'm not an electrician professional. So, I could be doing that wrong.
I was really dissappointed with the neohe 550. It is a great design and quite. The sleeved and removable wires was great. I was hoping to keep it far into the future for upgrades. Antec really dropped the ball on this particular unit. The problem maybe related only to asus motherboards, however, it's a PSU! That should be the last thing you would expect to have problems with when it comes to compatibility. If you have an asus, I would advice to go elsewhere for psu. Antec is great company. However, instead of RMA'ing the neohe, I'm going to just get my money back at CompUSA and stick with the Antec TruePowerII 480. The TPII-480 runs like a champ and is stable with my new system. It may not be SLI compliant, since it's not 500w or more, however, I would bet a good bit it would work just fine, if I ever add another 7900GT to my system. I guess I will find out, if I ever do go sli.

. Notice my SN starts with S0604
and is an A4
version. So, according to the link, it should work. However, this is not the case for me. Antec is still great PSU, just not the neohe. I give it two thumbs down.
