Seasonic X-650 review at Jonnyguru
http://www.jonnyguru.com/modules.php?na ... 2&reid=169
During testing, seems like the fan is off until 300W, it's very amazing though they are using an open-box testing.

DC/AC/efficiency/loss
62.4W/70.3W/88.8%/7.9W
134W/148W/90.5%/14W
It is THE most efficient PC PSU you can get by FAR. And silent for most SPCR-style systems during all operation, and for most other systems as well at least during idle.
Basically it looks like the king of all PSUs. Just can't afford one (nor do I need to replace another quality PSU for years anyway).

Did you read page 3? That's not an open boxnetmask254 wrote:though they are using an open-box testing.

However it's likely most of these are going into P182-type cases where they have their own thermal zone.JVM wrote: "Now, the company also told us temperature will determine the fan speed, so the fan may not turn off in a particularly cramped or poorly ventilated system."

I doubt it. Many have read the reviews and more will read them and people will want it, regardless of what kind of case they have--as long as it fits.lm wrote:However it's likely most of these are going into P182-type cases where they have their own thermal zone.JVM wrote: "Now, the company also told us temperature will determine the fan speed, so the fan may not turn off in a particularly cramped or poorly ventilated system."

Re: Seasonic X-650 review at Jonnyguru
I believe so, but think they have set a relatively high threshold to start up the fan, which is benefitial from their high efficiency.JVM wrote:"Now, the company also told us temperature will determine the fan speed, so the fan may not turn off in a particularly cramped or poorly ventilated system."netmask254 wrote:http://www.jonnyguru.com/modules.php?na ... 2&reid=169

For me, it's very interested on the temperature-noise profile after fan is turned on (wait for SPCR's review in future possibly). Otherwise, Antec's P18X or other cases who place the PSU at bottom and breath external air directly (e.g. Silverstone Raven2 & FT02) would be a good emulation of open-box.
Reviewed now also by Hardware Secrets that have PSUs as something of a speciality.
Top results all the way! (Noise levels not commented, other than that the fan is off while the PSU is somewhat cool.)

Nope, it's used to manage inrush current by shorting the NTC thermistors once the unit is powered up. If it disconnected the mains, you'd get no standby power.Ksanderash wrote:There is a relay on the pcb. I bet it disconnects the high voltage circuitry from AC main to avoid unwanted energy waste when standby.

My cheap InWin 30$ PSU draws about 14W AC in standby itself. The motherboard adds only 1.5W being connected by ATX24.
And if the standby module is connected directly to AC main, bypassing relay? This schematic solution can be viewed in Antec Signature SG-850. Maybe it isn't the case, but that is how high energy economy can be succeeded.If it disconnected the mains, you'd get no standby power.

Yeah... like "unplugging" heatsink from CPU/GPU under full load...Oklahoma Wolf wrote:The SM-268 wouldn't respond well to that... trust me. I speak from experience when I say replacing MOSFETs in there is no funfrostedflakes wrote:wired to a switch so they can shut it off for brief periods of time during the testing to take noise measurements.
And even just disabling active part of cooling would increase temperature very fast...
Everyone can easily check how fast CPU core temperatures rise when heat output rises from idle to full. Sudden dramatic decrease of cooling power would do the same.

So this source is mistaken? I thought Oleg Artamonov is enough honoured person concerning electronics, and PC PSUs especially, to do such mistakesThat isn't the case in this unit, or in the Signature either IIRC.
