Pros: If you are in the market for an SFX power supply, then you are aware that options are of course more limited, and trusted brands who make them are key to having a good, dependable one. Sometimes this comes at heavier price premium, and I usually love to poke fun at Corsair for having higher price to value (as in I usually think they find that fine line of how much they charge for what you get). Don’t get me wrong Corsair is and always has been quality brand in my book, but at a higher premium.
Now I started looking in to this SFX power supply and I am impressed with everything about it. Corsair left no detail of awesome out of this, and for just at $90 (at the time of this review) I think it is worth every cent. This is my humble opinion of course, and I’ll explain why.
The unit weighs in at just under 2 lbs. They condensed a lot in to it, it has an over kill amount of awesome features that cause this hefty little power supply to be a heavy hitter in the SFX arena.
It’s fully modular, not semi, but fully, that’s impressive for its form factor, delivery, customization options (should you want to have custom cabling done for it, in the event you have a tower to show it off in)
It is an 80+ Gold certified PSU, what this means is the following for efficiency:
- At 20% (load/utilization) its functioning at a solid theoretical 87% efficiency
- At 50% (load/utilization) its functioning at a very nice theoretical 90% efficiency
- At 100% (load/utilization) We’re back to the amazing theoretical of 87%
But it gets better as this little monster features Active PFC. Active PFC stands for active power factor correction, it utilizes onboard features to correct power issues (or attempt to do so) utilizing this feature can generate mid-high 90’s in efficiency consistently. Active PFC also plays a factor in to diminishing harmonics.
Stay with me, because there is a third factor to why this is all great.
Corsair has implemented a Zero RPM feature, which keeps the fan off until temperature controls tell that it needs to function for cooling. So how does this all somewhat tie together?
We already have a highly efficient PSU, in conjunction with Active PFC to reduce sound and increase the efficiency even more. Now adding in the Zero RPM feature, we might have one of the quietest, and strongest little SFX PSU’s on the market. Corsair has created a real contender, at a very easy value point.
Lastly, reading over all the features, while I hope to never have to test this on a power supply, it seems it would be what I consider ‘server grade dependable’
- Over volt protection (power surge)
- Under-volt protection (brown out esque situations)
- Short circuit protection
Cons: I sat here at an impasse in my mind. I feel obligated to point out cons, flaws, even things I am opinionated about that make me feel like this product could be, or do better… That’s just not the case for once. I’m surprised by this, if I had an award to offer, I would offer it to this SFX PSU.
So if you are looking for a con, I just can’t provide a good one…
I don’t like the way the felt (that the PSU was wrapped in) felt on my hands.
The logo for Corsair on the felt, was too dark and hard to see.
Overall Review: While the use of SFX PSU’s are more specific in hardware applications (form factor, and tower support requirements), this little beastly contender sits at the very top in my book. If you’re looking for something good, something quiet, something modular, something that delivers enough power for the current generation platforms, perhaps hold this one in high consideration.
A power supply is not just a power supply, it is the heart that pumps the blood to the entire machine. You want it to be strong, it is crucial and vital. While it is my subjective opinion, anything less, is no longer good enough for my standards. At least for now.
Pros: The build quality and electrical aspects of this power supply are great. My HTPC power right up and played HD movies just great. The high efficiency ratings mean this power supply will (and has) run very cool with scarcely ever a need for the far to even need to turn on. With the computer on and even under a load, the fan never came on for me (it never got hot enough). It turns on for a moment when the power is first tuned on, and then turns off until there is a need for air circulation.
The power output is great, especially for such a small form factor. The modular cables can allow some de-cluttering of small cases and improve air flow.
The warranty is for 5 years and that is a good amount of time. And should the power supply fail, it has plenty of safeties to prevent it from wiping out all the other parts of the system.
The aesthetics of the power supply are also great. Not many people will see it inside the case, but should you do a custom build on a flat surface you won't need to worry about the looks. The wires for the power supply are also all black and bonded together.
Cons: I have removed an egg from the power supply due to a number of small things that added up during the installation in my Mini-ITX case.
The first problem I had was the shroud around the power switch in the back hit the back plate of my case. There is no spec for saying how far from the edges any non-flat part needs to be (I checked), so it may not all be on corsair. Nonetheless, I had to flip the power supply 180 deg. in order for it to mount properly. However, doing this greatly reduced the clearance between the fan and the case, thus hampering air flow when the fan comes on.
The next problem I ran in to was the orientation of the SATA power connectors. The wire and plug of the SATA connector is 90 deg. This is not good for me as the drive I use is mounted flat on another part of the case. I was able to make it work, but there is more strain on the PCB connector than I like. A straight connector would have suite this particular case better.
Another problem I had was the way the modular power cords were bonded together. The wires were laminated in parallel so the height of the cable was the diameter if the wire and the width was the sum of the diameter of all the wires. This means the cable can really only bend up/down and not left/right.
Finally, where the modular cables plug in to the back of the power supply does not work well with my case as other things are cramping the space. This one is largely on me and the case and isn't entirely the design of the power supply. If the cables could plug in to the power supply at a 90 deg angle, it would be much easier.
Some of these problems are specific to my particular case, but small cases are cramped and attention needs to be given to where the power supply will be used.
Overall Review: Take a good look at the way the case is laid out and how everything will fit before choosing a modular power supply (which will require more room in the back for the power supply connections). Also pay attention to the locations of the power connections for the motherboard and peripherals. The pictures for this product are fairly accurate (note that in one picture, the white text describing the connectors is missing. The reality is that the white text is on the product and just missing from the picture for some reason).
Do your homework, and make sure it looks like it will fit. There is a chance you will be better off with a non-modular power supply or with one having more flexible wires. But there is also a chance the flat wires will be better for you. So do your homework and think about it.
+SMALL form factor
+Superior quality components
+plenty of cables for any install
When I received this power supply, I didn't realize it was a small form factor PS. The first thing I though when I opened the box, “well isn't that cute”, but powerful. So make sure you check dimensions for your case! It is great seeing these small form factor power supplies as PC's are shrinking. Especially now that that the power requirements for video cards has gotten back under control. I peered inside this power supply and was really impressed with the quality of the build and the components used. This is very important to me, as your power supply is the MOST important component of any system you build. Never skimp there..never! And you will have much more stability in your systems. After going modular, I can never go back to pre-made dongles of connectors. Once I finally got this little guy installed in my system it ran perfectly. I also checked all rails with an O-scope and all rails were exactly in tolerances and the power was very clean. For the quality of this little guy I would say it is fairly priced and present the user with a long lasting value that will probably outlast the pc it is put in. The fan was ultra quiet and I could barely discern it was even spinning!
-NO adapter plate
-Ribbon style cables.
-switch and cable socket not centered
- Only ONE SATA cable,
- no SATA adapters for Molex
Honestly, I am baffled for the price of this unit why an adapter plate for a regular ATX form factor was not included! Horrible move on that one Corsair, you should correct that mistake immediately. Like many others here I do not like ribbon style cables. It is because of their rigidity, tension, and poor twisting ability. They cause many problems and sometimes can actually cause failure in connectors, especially on delicate SATA connectors. I was able to adapt and make due. BTW my friends who read this take this one piece of friendly advice. NEVER mix power supply cables from other power supplies. I lost over 4TB's of movies once because I did. There apparently is no standard at the PS connectors for a specific layout. What really infuriated me though was there was no included Molex to SATA adapter. Because there is only one SATA cable with 4 connection, but it is practically impossible to only use one SATA connector to connect 3 or more devices
Last complaint, why is the power switch and plug not centered to the PS. It would make it much easier for people to mount in different cases. Even when they have to make their own adapter plate like I did.
Overall Review: UPDATE- As of 11/11/17 This power supply 12v Rail can no longer handle gaming with a gtx1060, It worked for almost a year so I can only conclude that the components are weak in this power supply. I cannot recommend this PS if you are going to put any type of significant load on it.
UPDATE 2: I have since had this product RMA from the fine people at Corsair. I have to say this is the first time in a long time that the RMA process was great. The people really do care about customer satisfaction.. At least I hope they treat everyone this way and not just a Neweggspert. Which I am pretty confident they do, because they did not have to honer the warranty since I did not buy the product. The process was pretty fast overall and I received a brand new power supply. So thank you Corsair..you just stole away some future business from EVGA! Due to good customer service!
Pros: super quiet and efficient, fan only comes on when it reaches a set internal temp.
really slick looking, not that many will notice this in a tiny case.
only got slightly warm to the touch in an o.c.'d I5/few big fans/8gb ram/dvd/ssd.
12.12 and 5.03 dcV under load.
Overall Review: this is made for small cases that take sfx ps hence the cabling will be short and will not bolt into an atx opening although you can buy an adapter and longer cables.
Pros: Modular cables = less mess since you only use what you need.
80 Plus Gold certified (I saw a 10% drop in draw at the wall compared to the stock Dell PSU it replaced in my XPS 8700).
Whisper quiet, I can't hear it over my GPU fans.
Quality build. Solid, heavy. Built like a tank.
5 year warranty.
Cons: 90 degree SATA power might be an issue for some. I was able to work around it.
Overall Review: Perfect fit in my Dell XPS 8700 that had a PSU that was dying out of warranty (reboots, etc.). Swapped it in in under 20 minutes and my kill-a-watt showed around 10% improvement in power usage and no more random reboots. Excellent product!
Pros: • Modular cables – use only what you need. Fully modular.
• 80 Plus GOLD Certified.
• As quiet as a PSU can get. Even after loading up the unit with my power sucking video card.
• Quality design and finish
• Minimal packaging.
• 5 year warranty (see other thoughts).
• Overall, an excellent PSU.
Cons: • Power cable from PSU to MB is too long for my build – the PSU and MB power connector are close together. Because it is thick, it is hard to hide and tuck away. I guess I would pay a bit more to get two or three optional length cables. Because the unit is modular, this would be an upsell.
• Ribbon cables are not for me: I really prefer them to be sheathed
Overall Review: • Corsair is a good company. Warranties for hardware are usually a given. Corsair is excellent with warranty replacement. The difference between Corsair and other manufacturers of PSU units is that I TRUST Corsair not to blow up and set my house on fire.
• A 5 year warranty is good when considering a PSU. I have been building machines for years and know that PSUs will die an angry death within the first year, or will last seemingly forever. My current rig is a Corsair 750 that has been going strong for 7 years now.
• My build was in a “SILVERSTONE Black Aluminum skin reinforced plastic front panel, 0.8mm SECC body MILO Series ML03B Micro ATX Media Center / HTPC Case” with Silverstone SFX to ATX power supply adapter bracket. The case has the room for a full power supply, but with this power supply, I get more room. Bonus!
• The quiet fan operation is fantastic for an HTPC, where you do not want to know it is there. Love it.
• I got the total power draw up to 265W and the fan did come on – I think it was because of the poor air circulation of where my HTPC is – it is in a somewhat open wooden console. I can feel the heat, so the fan must be driven off of that, obviously. However, when the HTPC was idle, the fan did not come on – at least not when I checked it multiple times.
Pros: We tested this Corsair SF450 450W SFX 80 Plug Gold Modular PSU in two different systems, a small form-factor home server and an ITX gaming HTPC, and in both cases it performed flawlessly, delivering the power needed to keep the systems up and running smoothly.
Solid build quality.
Fully modular design.
ATX quality in an SFX form-factor.
80 Plus Gold Certified.
5 Year Warranty!
Corsair, a trusted name in the industry.
It had more than enough power to handle our mini-ITX AMD A10-7850K based gaming HTPC, running 8GB of Radeon DDR3 1600 and an MSI R7 370. Have a more powerful ITX build in mind? Go for the 600W version!
The modular design means no unnecessary clutter or air-flow obstruction in your small form-factor build. It's quiet operation with smart fan control means no loud fan noise during your gaming sessions or when trying to watch movies or streaming TV. Overall, this is just a fantastic little PSU!
Cons: There were no notable cons during our testing.
Overall Review: This Corsair SF450 450W SFX 80 Plug Gold Modular PSU is a great option for small form factor builds where quality power is needed! So if you're in the market for an SFX PSU, then this little powerhouse gem needs to be at the top of your list.
Pros: Opened the box and was really surprised by the small size. Used to brick like power supplies of the past. Finally, the form factor of power supplies is going the way of CPUs. Replaced my older 600w Corsair that is about a year old, and the sound level of my system has really diminished. Night and day contrast. I would recommend this power supply on the ability to lower decibel levels alone.
With all the modular cables plugged in and comparing it to the elder Corsair Power Supply I replaced, it is akin to handling a stalk of brocoli compared to a fat octopus.
Runs, cool quiet and efficient. Perfect for a small form factor build for medium gaming and home entertainment streaming.
Yes, it costs a little more than older yet more powerful power supplies, but I doubt you will miss the heat and noise of last year's upgrade cycle. Highly recommended.
