Great so far.

Rating + 5
Tech Level Tech Level: high - Ownership: 1 week to 1 month
Pros: This PSU is very quiet, even while gaming. Probably why Seasonic's are so popular with the HTPC and silent PC crowd. It's one of the first power supplies with a >= 80% efficiency rating so your money goes further. Sleeved cables, modular connectors, and a big variety of extra cables, including 4 pci-e connectors. Voltages stay very constant. IDU reports 12.000V, 3.300V, etc. with very little variation, within thousandths.
Cons: None so far.
Other Thoughts: My computer was acting up with the Antec TP2-550 so I decided to get this one, and all issues went away.

Seasonic OEM's most Antecs PSU's, but seem to be of higher quality? Only time will tell.

I hated to spend this much on a PSU but I hated to burn up the rest of my system too with an inferior unit.

My setup is a Antec P180, Intel E6600 and D975XBX, 2 hdd, and eVGA 7950GX2.

This user purchased this item from Newegg
Pros: High build quality; Unit is quiter than hard drives and case fans. Air has never been above room temperature coming out. Stable
Cons: Cost. Very tight fit in a Thermaltake Armor case. It can be put in, but be patient.
Other Thoughts: Seasonic was a brand I've never heard of. I read a couple reviews, and decided to give them a shot after some issues with An***. I've bought three since (550,600,700) and will not buy any other brand. You get what you pay for.

Tech Level Tech Level: average - Ownership: less than 1 day
This user purchased this item from Newegg
Pros: quiet
well constructed cables
Cons: only worked for a few minutes and then the 12v rails gave it up had to RMA
Have to mount it upside down in a case like the Antec 1200 or 900 (not a big deal)
Other Thoughts: Have to give this a low rating but it sure is a nice PS

Tech Level Tech Level: somewhat high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: Quiet, rock solid, modular.
Cons: Somewhat stiff cables.
Other Thoughts: This PSU went into my Antec P182 case as a long-term investment. I'm planning on it lasting me through at least 1-2 builds, and so far, I can say that it's doing so. It is dead silent, and I've never had a problem related to power with the system. The cables were long enough to reach all the connections I needed them to - even when routed through the significantly longer cable-management systems of the Antec case. The modular system is nice because it means I don't have extra cables clogging up the inside of the case. The cables WERE a little on the stiff side, but the overall quality of the PSU more than makes up for the minor inconvenience of the stiff cabling.

Tech Level Tech Level: high - Ownership: 1 month to 1 year
This user purchased this item from Newegg
Pros: This is a quite PSU. I have owned dozens of SeaSonic PSU's and have never really had a noisy one. This one has nice sleaved cables. Almost all of the cables have good length. all the cable lengths were good and It installed nice into my P-180 with the exception of one.
Cons: The 8 pin CPU Cable is to short. the 4 pin is long enough though. you would think they would make these the same length.
Other Thoughts: I have a P-180 case, Asus P6T deluxe v2, With a a Zalman led9900. The 8 pin power cable was short and would not reach although the 4 pin would. I found this to be ridiculous. the cable extension cost me around 8 bucks. thought that was to high priced. but all in all great power supply.
