Pretty happy with with this so far.,
After my old power supply’s fan started to make noise I decided to just go with this fanless one to hopefully get rid of any future problem like that. The power supply has to be positioned so it’s vents face up and they recommend a well ventilated case.
My case (Antec Solo II) actually has a vent right above this so it works out well but a well ventilated chassis will do just fine.
I also tested power consumption between this and my older power supply; The “80 plus gold” is no joke… with my CPU and video card at full load my old power supply pulled 302 watts, with this one it’s down to 280 watts…
Anyways so far I’m happy as the quality of this looks superb but if anything changes I’ll update this review.

|Painful high-pitched noises!,
I recently bought two of these and built two identical computers. Unfortunately, there is persistent high-frequency noise coming from both supplies. The noise is a combination of constant whining and intermittent sounds that almost sound like beeping.
I’ve tried to overlook the noise, but it’s actually a bit painful being in the same room with it. Even strangers that didn’t know about it upfront have commented and asked to move rooms.
I contacted Seasonic and received a prompt, professional reply stating: “… we have noticed that in certain configurations, there seems to be a feed back look from MB or VGA to the PSU and then the PSU amplifies the sound. We see it often as system dependent…Regardless, the noise has no bearing on the quality, performance and reliability of your power supply.”
I’ve tried reconfiguring the cabling and system configurations. Some are better, some are worse, but I’ve never been able to get rid of the noise.
There’s really only one reason to get an expensive, fanless power supply: quiet. On that note, these units fail miserably for me. They’ll be heading back soon.
Credit where it’s due: this is a beautifully made unit that oozes quality. It even comes packed in a soft drawstring pouch with an additional sturdy, Velcro bag for cables. There’s also a lot to be said for such direct, honest and timely responsiveness from tech support. I really wish I could keep these power supplies.

|Efficient, slightly noisy until you break it in,
EDITED TO ADD: I think this machine needs a break-in period, because after about 100 hours of use, the noise disappeared.
First, I love the efficiency. This baby pays for itself over time, if your old PSU was less efficient. It’s near 90-91% efficiency for a huge part of its rated specs, like 10% load all the way up to 100% load (460W). Second, 460W is enough for all but the most power-hungry systems. A top CPU, near-top GPU, mobo, a few hard drives and an optical drive, RAM, and a few USB accessories will eat less than 460 watts unless you overvolt/overclock. The main downsides are that it has to be installed facing holes-up, so dirt can drift down into it over time (so you can’t use this with most cases where the PSU mounts on top unless there is a hole on top of your case); and it also occasionally emits a high-pitched sound that I find annoying. It’s been doing so less and less each day I’ve owned it, though. I got a cheap filter intended for a case fan, and placed it on top of the PSU to prevent dust from drifting down into it.
