Corsair AX Series, AX850, 850 Watt, 80+ Titanium Certified, Fully Modular Power Supply

This PSU is an absolute unit. With the titanium rating and being from Corsair you should expect nothing less but the best. PSU is dead silent, never heard any fan sounds. Power distribution is VERY stable and has miniscule to no fluctuations. Cable management is a breeze with full modularity. Installation was a pleasure and very quick. The badges and kit that comes with the PSU are top notch quality. It comes with many many different cables, a handy transport bag with everything you could to think of. This took my streaming PC to the next level. By the way, EXPECT TO SAVE, I’ve saved a consistent $10 a month off my energy bill just switching to this PSU alone.

I have been building PCs for over 35 years and I use Corsair power supplies in many of them. This company's rep is still very good. I have plenty of power for my accessories. I highly recommend these power supplies to all who need reliable and energy efficient power for their home-built PCs.

Got this to do some upgrades to my old rig. New case, fans, cooler and a CPU/GPU overclock later and my 6 year old PC is now more like a 2 year old PC haha.

Great PSU, very quiet, with an amazing efficiency and also modular with is a plus.

comes with all the cables you will need for the current ASUS Crosshair MOBO. Super quite. and runs cool at 450w loading. Nicely labeled and package. Expensive but is worth it. So far it has not blown up my system , been in operation for about 2 months straight.

I made a choice to invest in a high-end power supply to last me the next decade or so with great energy efficiency, and the AX850 fit the bill.What's great about it so far?Upon receiving the unit, the AX850 came in a padded box with optional magnetic strips to showcase the PSU, and a pouch containing all the essential cables for your PC. These cables do have a slight issue, which I will address later down this review.The unit itself is sturdy, and comes with a large fan to cool itself down under heavy load. Pretty much your standard PSU nowadays, except much more premium than the other PSUs on the market. It's based off a design from Seasonic, so you can ensure the reliability of this unit to be excellent. Overall it's designed well for the price range it is at.The bad?There's no digital power meter to gauge how much your PC is consuming while at idle or under load, and the cables that come with the PSU itself are quite stiff and tough to work with, especially for those building in a SFX computer. I'd recommend going aftermarket for the ease of installation to give you some peace of mind and well, no stress while plugging things in.

I cannot find any faults with this power supply. So far, it's been running smooth, quiet, and with zero hiccups.

I have total 28 SSDs in my PC. First I tried EVGA 1000 G3, but it has only 3 SATA and 1 Perif. The SATA cables have only 3 ports each so total 9 SATAs. I bought many y-splitter cables to connect all the SSDs, but it ended up with unstable disk access.This PSU (Corsair AX850) has 4 SATA and 2 Perif. Each SATA cables have 4 ports each so total 16 SATAs. I still have to use some y-splitter cables, but all SSDs are accessible all the time.I'm very happy with this PSU.

great unit, couldn't ask for much better, install was easy , although a tad tight in my case, being modular is a bonus so you can take out wires you will never need. never hear units fans and can shut the fans off ( mine stay on but is silent anyway) .. came with plenty of plugs and a nice wrap for extras plugs. would recommend for sure , this PSU has no issues running my system (which is a AMD 2700x with a RTX 2070super 32GB RAM and 1TB M2.SSD with another couple SSD .

What can I say?! It's a top notch power supply from Corsair. Dead quiet and my PC never complains!

Nothing else that I could ask for. It's a bit expensive, I guess, but having built cheaper PCs in the past, you do get what you pay for here.

A very efficient and silent PSU that can supported the latest generation high power GPU cards.

Excellent Power supply. Très silencieux avec son mode fanless.Je l'ai mis dans le bas de mon boîtier, mais pointant vers le haut vue que j'utilise le mode fanless. C'est la configuration recommandée dans ce scénario.
