Specifications and Packaging
The Seasonic Snow Silent-750 power supply is rated for a combined, continuous output power of up to 750 watts and comes with all modular cables. The PSU includes universal AC line input (automatically adjusts to the AC line voltage) and active PFC, which makes the unit more environmentally friendly to the local power grid. The Snow Silent-750 features a single +12V rail that can deliver up to 62A (744W) of power. The power supply is also ErP Lot 6 2013 compliant and Intel Haswell processor ready.

Dimensions: 170 x 150 x 86mm (D x W x H)
Packaging and Parts
The Seasonic Snow Silent-750 power supply arrived securely packed inside a sealed retail box that highlights the unit's main features and specifications.
Like all premium Seasonic power supplies, the PSU is nicely protected inside a cloth bag; but instead of the traditional black, this time we have a white bag with Platinum lettering.
In addition to the power supply the package includes a heavy duty power cord, mounting screws, Seasonic name badge, a multi-language Owner’s Manual, Warranty card, Velcro cable ties, wire ties, and a white box containing the modular cables.
The Seasonic Snow Silent-750 PSU comes with twelve modular cables and one 4-pin FDD cable adapter.
(1) CPU 8/4 pin, (1) CPU 8 pin, (1) M/B 24/20 pin, and (4) PCI-E 8/6 pin
(1) 4-pin FDD adapter, (2) peripheral 4-pin, and (3) SATA
The only thing I would like
The only thing I would like to see is 2-4 fan headers for semi-passive case fans.
Also 15-20% passive operation threshold (X-series) makes more sense then 50% as it is kind of hard to dissipate 375W out of the case without a fan.
I’m sure that you’re mistaken
I’m sure that you’re mistaken about the 375 watt dissipation. At 92% efficient, it would be something like 30 watts, before the fan kicks on.
I have had zero issues with any of the Seasonic power supplies that I’ve purchased and have an older 750 watt model in my main rig. I would definitely consider something like this for a future high-end build.
Exactly. The rest of the heat
Exactly. The rest of the heat is energy used by the PC though it would be more than 8% heat dissipated by the PSU since it would suck some heat back into the power supply.
That’s why it is also based on the temperature.
I was talking computer case
I was talking computer case not power supply case. If you deliver 375W to power your computer you need to get rid at least this amount of heat from the computer case.
Would it be easy to swap the
Would it be easy to swap the fan out for something like a Noctua? I believe some of their 140mm fans work in 120mm openings.
Why would you do that when
Why would you do that when one of the main reasons is to get the special fan? Does Noctua even make fans or do they just rebrand too?
Very nice, but why is it
Very nice, but why is it upside down? Everything is oriented as if the fan is expected to be pointing up, but in almost all cases it will be installed with the fan pointing down. Old cases put the PSU above the CPU with the fan down, and modern cases put the PSU at the bottom with the fan pointing down to pull in outside air from underneath. Why would they be expecting the fan to usually point up?
Valid question is why there
Valid question is why there are so few cases where motherboard is turned 90 degrees.
Actually, there might be more
Actually, there might be more people than you think installing the PSU with the fan up (myself included). With a PSU mounted in the bottom of an ATX case with the fan up – it adds to overall case cooling. This can help suck warm case air out of the sometimes stagnant area below the GPU card. The trade-off is causing the PSU to run a little warmer than it would with the fan down (sucking cool, outside air) but good PSUs like the Seasonic, are rated for up to 50 deg C operation. Not for everyone, but a good option for some.
The fan is sucking air in,
The fan is sucking air in, not pushing air out. It’s blowing over the internals of the psu. If it was installed on the top of a case it would act as an exhaust. Which would be optimal as heat rises.
At page 3, I think that fan
At page 3, I think that fan curve hysteresis is actually increased. Reducing hysteresis actually increasing the frequency of fan switching on-off when temperature is near equilibrium at setpoint.
