Pros: - Semi Modular design is great for micro atx builds!!
- continuous running 120mm fan but fairly quite
- Solid construction & stable voltages
- Tons of connectors for everything - whatever you have it will power it.
Cons: - I've been running this CX450 for the past few weeks on my test bench powering an old PhenomII and still haven't seen any hiccups or problems with it. Corsair makes great PSU's so I don't foresee having any issues.
Other Thoughts: Wish I had more to say about this PSU but it's been great. It's honstly the quietest part of the test bench compared to the Chipset cooler, CPU cooler and video card. The Corsair fan completely outperforms all of them. My test rig which I've had lying around is a PhenomII X4 945 3.0ghz, 4GB Ram, nVidia GeForce GTX 285 running on a PNY SSD. So that's pretty good power draw even at idle and it's been great. Highly recommended.READ FULL REVIEW
Pros: - Inexpensive
- Small USB, will easily fit beside other USB devices
- Works just fine on Windows 8.1 & Windows 10 machines but drivers WILL be needed
- No dropped connection during the 2 weeks of testing - very reliable
- 802.11AC throughput is phenomenal for such a small adapter!
Cons: - No 802.11n 2.4Ghz wireless capabilities - no, it will not see any G or N 2.4Ghz Based networks... AC Only
- Because of AC only - range will suffer a bit as AC isn't meant to give improved range over throughput
- Dislikes USB 2.0 ports on AMD APU based platforms / Seems to work fine on Intel Z170 Chipset USB 2.0
- Windows will not recognize this adapter out of the box - be prepared to install drivers
*this is more of an observation, but this little adapter seems to run hot. But after 2 weeks of constant use it hasn't been a problem
Other Thoughts: Testing was performed with the following devices. I use a Buffalo AirStation Extreme AC1900 router. I used my HTC One M7 with AC Wifi for comparison, and Speedtest.net for the results below.
Bedroom 20ft from Router in Living Room
TP Link Archer T1U -44 to -46 db 50.66 Mbps Down / 7.59 Up
HTC One M7 Phone -49 to -51 db 50.56 Mbps Down / 7.44 Up
Bathroom 30ft (farthest point + most walls in between device and router)
TP Link Archer T1U -57 to -69 db 16.80 Mbps Down / 6.19 Up ( first test timed out but news sites & youtube loaded slowly)
HTC One M7 Phone - 54 to -65 db 32.99 Mbps Down / 7.78 Up
Outside Back Deck Area 30ft
TP Link Archer T1U - 53 to -56 db 43.50 Mbps Down / 7.67 Up
HTC One M7 Phone - 54 to -60 db 57.59 Mbps Down / 7.80 Up
So there you have it. My home is a modest two story with close to 1600sq ft. of space and I was able to use my laptop in all areas of the house. So for an average home I think this little adapter would serve many of you quite well. If you are looking for range though you should look elsewhere. As it only sees AC networks you'll be disapointed if you need to go much further than 30ft or so from the router. But inside that range it's speed and reliability is very good. Remember, you need to have an 802.11AC based router, if your still stuck on N or any 2.4Ghz tech this is not the adapter for you.
With it only seeing AC networks I think this really limits it's usefulness. With it's lack of working well on USB 2.0 on AMD (who knows why) you can't really recommend it for older laptops that the Wifi Adapter have failed in to replace them. Most that old won't have USB 3.0 ports and those that do I really doubt their wifi cards have failed or will fail any time soon. Alternatively, most newer budget laptops only have N 2.4Ghz radios, so this would be a great way to upgrade that laptop to better utilize your 5Ghz AC network. If you need that extra network speed this is a great way to get there. Or, also a great alternative for a HTPC or Server that you want to keep close to the action but don't want to run an extra cable to have to deal with. I'd love to give it 5 stars but with the lack of 2.4Ghz and it's pickiness on AMD USB 2.0 ports I feel 4 is appropriate. But performance is there! Still recommended.
Pros: *Absolutely Silent - they weren't kidding!!! THE FAN WON'T MOVE UNLESS TRULY STRESSED
*Modular Design - I think this is the way to go these days to keep air flow & cable management at a premium
*Solid build construction
*Corsair Link compatible for even greater finite control!
*Incredibly stable voltages and handles everything like a champ!!!
*Professional packaging - to those that care. The cables came neatly packed in a dedicated pouch. Solid protection for shipping!!
Cons: *Corsair LInk Cable did not come with my review unit. Matter of fact, several of the Corsair products I've purchased or reviewed that had Corsair Link Capability seem to not come with the cable. Which is really disappointing. Corsair Link is a cool feature that users would find invaluable once enabled.
*Though I was unable to truly verify it appears that the +5v & -5v rails were a bit off of their targets according to CPUID HW Monitor app. Claiming just +4.435v and -6.400v respectively. With that said, CPUID looked to have trouble even reading the Gigabyte Z170 Gaming 7 board so take this observation as just that and not necessarily fact. Otherwise, this PSU has been rock solid. I'm impressed.
Other Thoughts: As running an 850W PSU was complete overkill for me, as a review item I tried my best to slap this thing around a bit. My rigs specs are the following:
Intel Core i5 6600K @ 4.1Ghz (mild overclock I know - max is 4.6 but I can't get it to run stable yet)
Gigabyte Z170x Gaming7 Motherboard
GeiL 16GB (4x4) DDR4 2400 Ram - Quad Channel
Samsung 850 Evo 250GB, FaSpeed 250GB SSD, 2x Seagate 750GB HDD, 2x WD Green 2TB HDD
MSI Radeon R9 370 2GB GDDR5 Video Card
Corsair H80i CPU Cooler
Not top of the line by any stretch but a decent machine to be sure. Again, my goal was to find out if/when the RM850's thermal sensors would start to initiate cooling and trip the fan on. With my trusty P3 meter at the wall I got to work.
System Boot peaked at 91w. No Fan. Next, I recently picked up Street Fighter 5 for PC since I don't own a PS4.
Street Fighter 5 Online Ranked peaked at 139w. No Fan. Next I fired up Project Cars, knowing it demands surpass SF5 by a lot.
Project Cars 10 minute prototype racing peaked at 175w. Still No Fan. Shocked... I wanted to see if the magic number was 200 or even higher. So in addition to running Project Cars, I fired up 6 instances of CPU Burn In and left all my browsers open. 186w later... still nothing. Finally... I ran 3D Mark Vantage benchmark which got me close to my 200w goal with 196w's at full load. And you guessed it... the PSU fan never spun up. Not even once! That feature is not just marketing guys blowing smoke, it's the real deal.
I'm sorry guys, wish I had a tougher rig to throw at this thing. Maybe I shouldn't of given away my FX-8350 ;) It could break 200w easy! lol But, there you have it. Those of you looking for performance, but most importantly silence look no further. With most of our rigs sitting between 50 & 100w on the daily I suspect the fan may only turn on a few times a year. Impressed. Indeed.
