Corsair CV450, CV Series, 80 PLUS Bronze Certified, 450 Watt Non-Modular Power Supply - Black

This is a review for the 450 W version (modular)I'm not affiliated so I only speak from a hobbyist perspectiveI've used this PSU twice. Once in 2017, and now in 2020 as well. You can trust a brand like crucial and I think it's the best value for money. My philosophy is to save a buck and spend on a reliable PSU (like this one)I can confirm it runs well with the following parts so far:i54570si74790Ryzen 5 3600Nvidia GT1030Nvidia GTX 1650Nvidia GTX 1060 GB...plus SSDs and RAM and bunch of coolers (7x Arctic 90 mm)Being modular it's a plus, saving you from cable clutter etc. The cables themselves are properly protectedSo...for a low TDP system based on the above (don't trust me and don't PSU calculator before choosing a PSU), this is the one for me. It's well balance between stability and power delivery, quiet, small to fit any standard ATX case, and hasn't crashed (even while OCing the 1650)

When I first looked at the CorsairCV550 I thought that a bit expensive but I'm glad I bought it, the build quality is very good the fan is quiet and the cables are good quality and there is lots of SATA power connections and various other power connections and PCI-E connections needed on ATX boards.I have bought cheaper PSU's in the past and you need to start adding extra SATA and PCI-e cables etc.

Since this is a corsair product I had high expectations despite the moderate price. I'm happy to report these were met, the power supply has had no issues so far and the fan is quieter than my case fans by a significant margin (Golden Field 120mm white led).The cables are black sleeved as you can see in the photo which is great for maintaining aesthetics, although I'm not sure as to why corsair wouldn't advertise this on the amazon listing and instead show ugly ketchup and mustard cables.450w is enough for most (definitely not all) budget 1st 2nd and 3 gen ryzen 3 and 5 builds with graphics cards under the GTX 1660 super in terms of power draw (above this and you may want to consider more wattage or simply better quality with the CX/TM lineup). Always check your total system power draw with a service like PC part picker before building. Edit: on the amd side RX 570 is ideally the highest power drawing card you want to go with , an RX 580 should be fine but I wouldn't reccomend it and neither does AMD.Overall for the sale price of £23 that I paid this is a shockingly good deal. Time will tell how it holds up.

V SERIES™ CV550 POWER SUPPLY QUIET AND DEPENDABLE 80 PLUS BRONZE EFFICIENCYULTRA EFFICIENT CV series is 80 PLUS Bronze certified, providing up to 88% efficiency for less heat and lower energy costs. CONTINUOUS, RELIABLE OUTPUT Like all CORSAIR power supplies, the CV Series does exactly what it says it does: deliver continuous power at full capacity, no matter which wattage variant you choose. LOW-NOISE OPERATION A 120mm thermally controlled low-noise cooling fan only spins at high speed when your power supply is under heavy stress, slowing down for quieter operation at lower loads. COMPACT DESIGN CV series enclosures are only 125mm long, ensuring an easy fit in almost all modern PC cases.

Corsair CX 450W:Overview:A well priced and well performing power supply for prebuilts, office computers or lower power draw gaming PCs. The horrors of the Corsair CX (GREEN) models aren't to be confused as this is a well rated unit with 80+ Bronze efficiency.I needed this for a R3 1200 | GTX 1050 system, with some headroom for a small upgrade; a higher end system would be better suited with a higher wattage unit in order to not stress the PSU and keep within the highest point of the 80+ specification - efficiency rating.Advantages:£40, going budget doesn't always mean a huge loss of quality or features80+ Bronze RatedSimple, not industrial and not 'gamery' aesthetic with a well fitting label.Fan noise doesn't stand out from either my Corsair AF 120 (Quiet Editions) or my AMD Ryzen Wraith Stealth cooler.Disadvantages / Desired improvements:One feature you do miss out on is modular cables (At least for the unit I got), and since the cables are wrapped and have some 'heft' to them cable management isn't as much of a breeze as with modular units.Whilst a low wattage unit, which also runs "cool" to "luke warm" from idle to full load; there is no ventilation on the front of the PSU - the side that faces inside your case. Again, this seems like a minor flaw due to the small amount of power it will put out, but if I was running my computer under load 24/7 as a, say, budget home server - I would get slightly uncomfortable about any possible hotspots.Though not exactly a disadvantage; I've only had this for a couple of months, it may fail on me tomorrow as it is my first time using this specific line-up, so do take what I say with a grain of salt as your results may vary.

I have two SSD and two SATA hard drives in my PC. I had repeated problems with the SATA hard drives reporting errors or being unreadable. I read an article that said it can be caused by a weak PSU. This seemed to be confirmed by the failures happening when I plugged something into the USB to be charged such as my phone. Since replacing with this PSU I have had no further problems with the hard drives.It is also much quieter than my old PSU. The PC is under the desk and I can hardly hear any noise from it now.
