Seasonic Snow Silent 750W Power Supply Review

Packaging, Contents, Exterior And Cabling

Packaging

The box that the Snow Silent 750 comes in is similar to the one used for the 1050W unit. It has a white background and on the front, bottom-right corner, there is a small photo of the PSU along with the 80 PLUS Platinum badge; a capacity description is in the top-right corner. The technical and power specifications table is depicted on one side, while on the other side we find an angled photo of the PSU with the modular panel exposed.

On the back of the box, Seasonic highlights the most important features of this unit, devoting a small paragraph to each of them. These features include Platinum-rated efficiency, a modular panel with integrated DC-DC modules for lower energy loss, high-quality 105 °C electrolytic capacitors, a FDB fan and the hybrid fan operation. An interesting graph shows the fan speed in semi-passive and normal modes. According to it, up to typical loads and with 25 °C operating temperature, the PSU operates in passive mode, outputting zero noise.

Contents

Inside the box, the PSU is protected by packing foam, and it is also wrapped in a white bag with Seasonic's logo on it. Additionally, the bundle includes two sets of Velcro straps, several zip ties, a set of fixing bolts, a case badge, an AC power cord and the modular cables. There is also an owner's manual along with a piece of paper depicting the PCIe power connector recommendation for graphics cards with more than 230W power consumption. For high-end GPUs, Seasonic recommends using two PCIe cables (instead of only one with two connectors). Funny enough, the Snow Silent 750 doesn't have PCIe cables with two connectors; therefore, you have to use two PCIe cables for cards that have double PCIe inputs.

Exterior

The Snow Silent 750 features a unique look thanks to its white paint, white fan and brushed frame around the fan grill. However, we believe that Seasonic could have been more progressive in designing the unit's front, where a classic honeycomb-shaped exhaust grill is used. On the sides of the PSU, the letter "S" (for silence) is stamped onto the chassis, and a nice silver line enhances the look. The power specifications label is placed on the bottom of the unit. Finally, the dimensions of the Snow Silent 750 are smaller compared with the 1050W model, since it uses a more compact PCB.

The PSU's modular panel has lots of sockets, including six with eight pins each. Unfortunately, the on/off switch for toggling hybrid mode is located on the back side of the PSU, so accessing your system's internals becomes necessary if you want to change fan modes.

Cabling

We would prefer to see white-colored cables to match the chassis. Unfortunately, Seasonic includes black cables, probably because the cost of white cables would need to be passed along. The stealth, black sleeved cables are all flat except for the ATX cable, which has the normal, round shape.

    Most likely they did it this way to avoid having two switches on the outside face of the PSU. If they had placed both switches there I can see people reaching around the back of their case to change fan modes and accidentally turning off their PC because they flipped the wrong switch.

    This would look awesome in my H440!

    Yea to be honest I prefer the fan/hybrid toggle on the INSIDE of my case anyway. I put my Seasonic Platinum 650W in hybrid mode a long time ago and forgot about it.

    I don't see any need to flip the switch on and off, in fact I can't think of a single good reason why I would ever want to touch the thing again. So for me, it would be a con to have the switch on the outside of the case.
  • Aris_Mp
    this switch is much smaller than the on/off one so it is really hard to mix them up. Also the on/off switch is harder to activate. In any case as a reviewer I see this as a con, not a serious though. Some users out there will share my opinion while others won't.

    If you were looking at the back of the PSU, then yes, but I'm assuming the more common situation where the user is reaching around the back of the case where they can't see. In this scenario, one would have to feel around the back with their hand so it's much easier to get it wrong. I almost never use the switch on the back of my PSU, so every two or three months when I DO use it, I have to fumble around in the back to find the switch. For your average user, having two switches back there would just be asking for trouble.

    A lot of companies are putting the hybrid switch on the inside of the PSU. Just like the new units EVGA is putting out. It makes no sense to put the switch on the outside due to confusion with the on/off switch

    180 dollars for this? No.
  • JQB45
    I'd pay $150-$180 USD for this PSU and not just because its pretty.

    For a rock-solid PSU with a 7-year warranty? This thing would power my next three or four computers. $180 for not having to buy another PSU for a decade is a damn good deal.

    Regarding the fan switch, my PSU has a similar feature, and honestly, I imagine most people would set it at installation and never change it. I sure haven't.

    Indeed a PSU is an investment, something that unfortunately most people cannot see or understand while on the same time they have no problem spending serious money on GPUs and CPUs.

    You can keep a good PSU for many system builds while a not reliable, cheap PSU besides breaking down fast can also destroy many of your system components.

    Been looking for this on jonnyguru.... the 1050 watter scored a 10 in build quality and performance. My son bought the 1000 G2 cause it was cheaper than the 750 at the time.... the 1000 G2 is way too dang noisy. This wuda been nice.

    I paid 54 dollars for a psu that its damn near the same quality.

    This psu in this review is horrendously overpriced.

    Getting a good deal on a PSU that was released a while ago is one thing. That PSU had and has an MSRP of $90. Not $54. It's also bronze rated. Not saying that is a bad thing or a relevant thing, but efficiency does affect the MSRP of PSU's.
  • JackNaylorPE
    1. The current price is MSRP and will hold until there's some competition from vendors. The 1050 came out at $255 ... its $202 now; once there are enough supplies in the channel, it will be $139-$144 ... probably less

    2. My son has a 1000 watt G2, I'd pay $50 if I didn't have to hear that fan all day, The G2 matched the performance and it's $105, the HX750i is surely worth the extra $10... The Antec HCG matches the BQ and it's $85

    3. But like anything else, if you want that binned GPU, the best overclocking MoBo, the price premium suffers from the law of diminishing returns. Michael Phelps made millions coming home from the Olympics with Gold Medals .... how much did the guy with the silvers make ?

    4. It is damn perty :)

    A real nice street racing engine might cost ya $15k .... wanna take 2/10's of a second off that and ya can spend $50k

    Yeah exactly it's an investment as much as the actual PC itself is. And I've seen enough builds on this site where I almost instantly recommend that people spend more money on a PSU. You're paying $350 for an i7 and $600 for a GTX 980TI, yet you won't pay more than $75 for a Corsair CX750. I mean WTF??? Like 99% of the time on this website the answer to most people's problems with their system is "buy a new PSU". And it is really sad when people don't see that's a huge investment.

    I have both 850W and 750W versions of the G2 and I've never seen an issue with either one in regards to noise.
  • junkeymonkey
    lots of folks just don't see a psu is the hart and life blood of a build and top stable build quality goes a long way.. spend 2000 bucks on a build and 64.95 on a psu .

    Especially when a 750 watt EVGA B2 is like $55

    Well... it's a matter of perspective. If you have two Gigabyte G1's, twin CPU fans, and say 6 case fans, you're not going to hear the PSU fan ... but if you invested a boatload of money in water cooling components, the radiator fans are spinning at 350 - 500 rpm under normal usage. The noise associated with that is below the audible range of hearing. To have that peace and quiet disturbed and your investment negated by the lack of a quiet PSU fan is disheartening.

    It's about time we get a white PSU.
  • JackNaylorPE
    Well there was this .... and it was $180 five years ago.

    NZXT Hale90 850W (9.5 performance / 10.0 build quality)

    This is better and cheaper considering inflation.

    That sure is one sexy PSU! I have the Seasonic 660W Platinum PSU, but I might haver to kick her to the curb for this fine young lady. I can just see her sitting inside my Enthoo Pro, now. That big window on the side of my Enthoo Pro would show her off real nicely. :P

    Nice job, Seasonic!
