They used to have a page on Corsair.com with a table that showed all of the features of each Corsair PSU and how they differ. It's not there anymore... or it's well hidden. The letters don't really mean anything, so it can be really confusing which Corsair PSU is better than another. So I put this list together. The PSUs below are ranked from "high end" to "low end": (If you want pictures, I've attached a representative of each series here: http://www.jongerow.com/Corsair_PSU_hierarchy/index.html) AX1600i: Titanium efficiency, fully modular, FDB fan with Zero RPM fan mode. All Japanese caps. Rated at 50°C. All analog ICs replaced with MCUs (fully digital). PSU has monitoring capability via LINK or iCUE. Has a very unique bridgeless totem-pole front end with GaN transistors. AX: Titanium efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU w/o monitoring. All Japanese caps. Rated at 50°C. Until I say otherwise, all of these PSUs use a LLC resonant front end and DC to DC for the +3.3V and +5V rails. HXi: Platinum efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU, but with monitoring. All Japanese caps. Rated at 50°C. HX: Platinum efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU w/o monitoring, but a switch to choose between single and multiple +12V rail. All Japanese caps. Rated at 50°C RMi: Gold efficiency, fully modular, FDB fan with Zero RPM fan mode, analog PSU, but with monitoring. All Japanese caps. Rated at 50°C RMx: Gold efficiency, fully modular, rifle bearing fan with Zero RPM fan mode. All Japanese caps. Rated at 50°C. From here on down, all of the PSUs are analog without any kind of monitoring or control via Corsair Link or iCUE. TX-M: Gold efficiency, semi-modular, rifle bearing fan w/o Zero RPM fan mode. All Japanese caps. Rated at 50°C RM (new): Gold efficiency, fully modular, rifle bearing fan with Zero RPM fan mode. Supports new Modern Standby Mode and meets new 2% efficiency requirement of 70%. No Japanese caps. Rated at 40°C. Vengeance Silver: 80 PLUS Silver efficiency, semi-modular, rifle bearing fan with Zero RPM fan mode. Has a switch to choose between single and multiple +12V rail. All Japanese caps. Rated at 40°C. CX: Bronze efficiency, non-modular, rifle bearing fan. Only Japanese bulk cap. Rated at 40°C. CX-M: Bronze efficiency, semi-modular, rifle bearing fan. This and the VS are the only Corsair PSUs that aren't LLC and have a double forward front end. That said, CX-M at least has DC to DC for the +3.3V and +5V. Only Japanese bulk cap. Rated at 40°C. CV650: New. Bronze efficiency, double forward with DC to DC for the +3.3V and +5V. CV: Simply nothing more than VS (see next bullet), but with Bronze efficiency. Sleeve bearing fan, no Jap caps, double forward, group regulated. VS: Regular 80 PLUS efficiency. Non-modular. Sleeve bearing fan. No Japanese caps. Rated at 30°C. Double forward and no DC to DC (group regulated). SFX PSUs: Corsair SFX PUSs are true SFX form factor and not the "unofficial" SFX-L form factor. They also come with very short cables because they're made for ITX builds. SF Platinum: 80 PLUS Platinum, fully modular, rifle bearing fan. SF Gold: 80 PLUS Gold, fully modular, rifle bearing fan. Older versions of the series names currently in production (the series has been updated, but they use the same name): AXi: Used to be a full line of Platinum digital power supplies with DBB fans. AX: Used to be Platinum and before that Gold efficiency and with DBB fans. The original Gold AX was Corsair's first fully modular Gold PSU. HX: Corsair's original PSU series. It was originally 80 PLUS, then Bronze, then Gold. It used to be semi-modular and always had a DBB fan until the most recent Platinum version. TX and TX-M: Use to be a semi-modular unit with Bronze efficiency. Totally overbuilt for a Bronze PSU and therefore too expensive. DBB fan. RM: Prior to the most recent RM and before the RMx and RMi, It only had a Japanese bulk cap and was only rated at 40°C. It did have an I2C connector that reported +12V rail load and fan speed to Corsair LINK. This was also the first Corsair PSU to use an MCU to incorporate a Zero RPM fan mode. Prior to this, an analog controller was used in both the AX Gold and second generation GS that was problematic due to using only temperature to determine if the fan should spin or not. Vengeance Bronze: 80 PLUS Bronze efficiency. Came in fixed cable and semi-modular versions. Rifle bearing fan w/o Zero RPM fan mode. All Japanese caps. Rated at 40°C. Replaced by Vengeance Silver. Completely discontinued series (not made any more and series names not reused): CS-M: Gold efficiency, semi-modular, rifle bearing fan w/o Zero RPM fan mode. Only Japanese bulk cap. Rated at 40°C. Replaced by TX-M. GS: Very similar feature-wise to CX-M (same topology, etc.) but with an R- G- B- fan that could be changed with a push button on the housing. There were two generations of this PSU. The first was just 80 PLUS efficienct. The second was 80 PLUS Bronze and had a crude, analog version of a zero RPM fan mode. VX: Was cheaper than HX, but still built like a tank and too expensive, so it didn't last long in the market.

I recently built a new computer and while plugging in my headphones i heard a very quiet rattling noise coming from the PSU. I have an HX1000 Platinum. It is very quiet and I can basically only hear it if I put my ear right next to it. It just stresses me out a bit because I dont want it to eventually lead to a bigger problem and damage my other components. Is this normal and does anybody have any idea what this is? (The video makes it sound 100x louder than it actually is) also that’s the only noise the PSU makes it’s very quiet if i’m not right next to it IMG_0657.MOV

As title said, I've tried contacting Corsair via Facebook, they told me that the Premium Sleeved Cables they selling are only compatible with RMx / RMi / SF PSU. I've compare the PSU of my HX1000 (non " i " ) and the RMx PSU. They do look the exact same. I was wondering if the cables be compatible with my HX PSU. Anyone here owns a HX PSU with their Premium Sleeved Cables ? I wanted to E-Mail Corsair but there isn't...I have to create a stupid account just to contact them..

Someone please help me I'm looking to build a computer and for my power supply I want to get it from corsair but I don't know what to get or what's the difference can someone please help me thanks

Can i use thermaltake sleeve cable ( https://www.thermaltake.com/products-model.aspx?id=C_00002832 ) on corsair hx1200?

Hey everyone. I am really curious with this and would like some opinions. I am planning to get another GTX 970 to run in SLI. But I currently own a Corsair HX750W PSU. Looking around on PSU calculators, I think I can get away with it, but am not to sure. The reason I am going for another GTX 970 for SLI is looking at performance numbers, they are within spitting distance of a GTX 980TI. (Which I want but a bit too expensive) I know going for the single card will reduce the wattage requirements, so I wont need to up my PSU, but I don't want to discard/Sell my PSU and a fully working GTX 970. Should I upgrade my PSU to an 850W along with the extra GPU? If so, what PSU's should I look at? (From the UK, so some brands are not available here) Requirements if needed to upgrade: Modular/Semi-Modular 80+ Gold or higher Support for multi-gpu (current card has 1x 8pin and 1x 6pin, second might have dual 6pins) Not too expensive - around £80-£100MAX. Thanks.

Hi there, I'm going to upgrade several parts of my pc an one of them is the psu. Currently i have one Asus gtx 980 ti in this system and in the near future (depending on how the technology progresses) i plan to add another 980 ti in SLI config in order to push the specs a little further. Now here is my dilemma. I'm stuck between the Corsair HX850i and the HX1000i. Do you think the 850w iteration of the psu will be enough to drive the SLI config or should i go for the 1000w version, keeping in mind that there is some $50 difference in price. I'll be overclocking both cards and i could go for a custom watercooling loop down the road. Here's the rest of my specs: CPU: i5-4690K 3.5 (overclocked to 4.6) - Corsair H100i GTX AIO Watercooling unit Motherboard: Asus z97-AR RAM: Corsair Vengence 2x8 GB Storage: Samsung 850 EVO 250 GB x2 and a Seagate Hybrid HDD 2TB Case: Corsair 760T And a dedicated sound card and several fans to cool it all down. Thanks for all the help in advance.

Today is the day when the PSU hit 6 years in service when i bought it and turned it on for the first time. I'm planning to put in some expensive gear so i got worried that maybe its time to retire it? Are there actualy any risk on running an old psu?

I'm buying a PSU for my new build, and are deciding between the Corsair HX1000i and RM1000. Which one is better? My priorities: Silence (under what load it can run passive and how audible coil whine it has when the fan does not spin) Noise level when the fan is spinning Performance The price difference is insignificant. I don't care about Corsair Link. I'm planning on having the system a couple of years. Thanks! PS. Sorry if this has already been posted. I CAN NOT find the search button :unsure:

Hello everyone. I'm building a new system in a Corsair Carbine Air 540 case with two separate, pre-build water cooling systems. Depending on my pick of systems this could be a H110 (for CPU) with a H90 (for GPU), the other way around, or two H110. However, one problem I always struggle with it what power supply I have to pick. I'm gonna do a lot of gaming on it, with one GPU for now, and record these games at the same time, while editing them later. I will not however be doing any overclocking, or not anytime soon. Nor will I add a second GPU for quiet some time. I'm also not sure what series I need to pick. I like the Corsair full modular PSU's, but do I pick a AX, RX, or HX? My system mainly needs to be quiet as well, so I was thinking about RX, but maybe someone here has bad experience with those. Please let me know what you would think is best for me.

and is it good quality? i currently have a CS 750M waiting for a RM 750 but i found out its not really that good so ill cancle the order,and order a HX (AX is just too expensive) so is HX made by a good company? specs: GTX 770 2gb OC GIGABYTE (in future ill buy the most two GTX 970 sli) i5 4690K 4ghz OCed 1 120gb SSD 1 1tb HDD Corsair H90 cooler GIGABYTE Z97X Corsair vengeance pro 2x4gb running at 1600mhz

As i heard RM has bad OEM ,Capacitors and its overheating, im currently waitng for one Some say theyre fine with it , i dont want to get a bad psu thatll ruin my pc I some say that AX is overpriced Im currently mostly on HX 750i side, is it worth extra 10€ for the i one?also AX?good OEM? And which does have the best producers? And isnt overheating, too noisy Im currently on a CS 750M i cant even hear Im a bit confused right now is RM really that bad? AX is a bit too much ,but worth it? 750i or 750? Difference Good OEMs? The psu should be good for two gigabyte gtx 970
