true power supply reviews are difficult to come across on YouTube and that there's a good reason for that I recommend you stick to sites like Tom's Hardware and Johnny guru for the fine details we can't test things like load regulation hold up time and ripple levels the equipment is just too expensive and I honestly doubt we'd ever realize a true ROI so simply put those topics are for the specialists and I'll happily defer to them but in this case there are a few things we can talk about and test I'd like you to meet the silverstone nightjar 450s XL the vnj 450 falls under the sfx elf form factor which is the awkward middle child between standard ATX and sfx power supplies it's an interesting size especially considering it won't fit in many small form factor cases including one my favorite the fractal design node 202 though to be fair silverstone themselves of do manufacture many cases for which this psu would be perfect you just gotta have one of those on hand but another issue is that silverstone doesn't include an S effects to ATX adapter either so unless you specifically got a case begging for SF XL which I doubt you'll need to buy an adapter online if you wish to use this PSU in a standard ATX case which is what most people have on hand I've linked one down below it by the way if you're interested if you want to pair this PSU with something larger than a conventional SF XL chassis what you will find in the box is a manual the unit modular cable sets and a power cable the PSU is fully modular and the cables are slightly shorter than ATX especially this a pin eps cable this one will not fit in a traditional ATX chassis it's way too short so you can definitely see you know how Silverstone sculpted this power supply to fit in their style case right in a case that supports s FX L but not necessarily ATX this unit by the way does come with four sets of eight pin VGA cables so if you want to run two graphics cards that are to eight pin cards apiece then you could power that through this unit although I doubt the wattage rating would be enough to run a dual graphics card config so you just have to kind of feel it out but in most cases it's not going to work you just have that breathing room if you want like a you know overcooked card that maybe has I don't know 3/8 pin connectors which is very hard to come by but in most cases you're not gonna worry about graphics card power at all with the unit like this next on the list is silver stones 80-plus platinum rating for this unit quite a large feat for such a small unit especially for one without a fan which is perhaps the biggest selling point here the idiot plus rating system scales system load with total power draw from the wall and a platinum rating signifies a minimum peak efficiency of a 92% this peak occurs somewhere around the 50% load which in this case is around 225 watts you're likely to go a bit higher than that in most builds you'll get around 300 watts or so but this is still plenty of breathing room for most conventional single CPU single GPU configurations recall that higher ratings yield lower energy losses in the form of heat when power from the wall is rectified and transformed the only tier higher than platinum is titanium by the way reserved for the most efficient PSUs on the market in this case though the NJ 450 is rating is more than satisfactory especially given its load wattage but perhaps the biggest selling point again of this unit is its fanless design and according to silverstone the unit is capable of maintaining a full load temperature of approximately 40 degrees celsius while not having a fan that is impressive you can imagine how technically difficult that was to achieve silverstone uses several grooved heat sinks along the frame of the unit to increase surface area and convection with the air and even when enclosed in a tight case basement the temperature remained safely below this level under loads I feel like this is extra breathing room just to you know cya right this is where I expected things to heat up quite a bit past spec but to my surprise Silverstone left significant Headroom in this 40 degree rating and actually took it upon myself to disassemble the unit I was a very pleased to see that they were passively cooling almost every major component in there from the inductors to the transformer they were all being passively cooled with thermal pads that were then contacting the shell of the PSU so they're using the entire frame of the unit to keep the components inside very cool and that's how they get rid of the necessity of a fan so a very unique engineering here and I expect we'll see more of this in the future only a few power supplies out there claim you know the fan design and this one here appears to be very well engineered at least from what I can tell by taking off the top and side panels it's such a strange like feeling I don't know listening to a dead silent power supply this thing makes no noise at all member this is converting AC to DC it's splitting up power loads along a single 12 volt rail like it's it's doing a lot of work and it is getting quite hard but the the elimination of a fan in here just makes it so I don't know alien like it's just that it's such a big step forward and I do expect that we'll see more like this in the future again but for now I mean there are very exclusive lineups that don't feature fans this is one of them the fact that they were able to keep it so small at the same time right SFX elf smaller than traditional ATX and delete the fan is I guess it's just an impressive feat I mean I tried listening for any noise at all I tried listening for coil 1 from the inductors any rattling in the transformer it is dead silent and it doesn't really make sense to even throw up a you know a DB graph because it doesn't compare to anything else with a fan I mean this is truly a silent unit so all of my initial testing has proven this to be a great power supply now long-term reliability is a different story but you guys know me if anything does happen even if it's a fault of my own I won't hesitate to expose it though I highly doubt this PSU will have any QC issues based on what I've seen and thus far so a great job Silverstone in my book now what you guys think in the comments below that's a different story possibly what power supply you sporting would you consider this for a small form-factor build I want to know in the comments down below let's duke it out if we disagree totally fine with that give this video a thumbs up thought it was cool dislike it if you feel the complete opposite or if you hate everything about life you can click that red subscribe button if you haven't already and stay tuned for more
