The Differences Between All of Corsair's PSU Lines
Channel: Hardware Sugar
Date: 2020-05-09

To make things simple we generally recommend the Corsair RMx line.
► Corsair RM650x from Amazon https://amzn.to/35GN8b5
► Corsair RM750x from Amazon https://amzn.to/36IGII0
(I do get a small cut from any purchase made through the above Amazon affiliate link.)

Corsair PSUs. What's the difference between the VS, CV, CX, GS, CS, TX-M, RM, RMx, HX, AX, SF, RMi, HXi and AXi lines? Their naming scheme is confusing. They all look the same. They all point back to the 80+ standard.

We try to give a general, techno babble free, overview.
0:00 Start

3:19 VS Line
- 80+ White/Regular 80+ (lowest 80+ level)
- the internals are based on an old design, what you buy if you want quality but really can’t afford anything else
- only sold outside of the US

4:01 CV Line
-VS line tweaked to make it more efficient (internally the active Power-factor correction (PFC) circuit section is upgraded and tuned to achieve the 80 PLUS Bronze efficiency mark)
- 80 Plus Bronze

4:29 CX Line
- latest iteration is CX2017 which is supposedly meets 80+ Silver performance but is only advertised at 80+ Bronze
- good +12V rail

6:03 GS Line (discontinued)
- 80+ Bronze
- aimed towards the budget gamer
- featured RGB lights

6:49 CS
- first of the mid range PSU  series
- 80+ Gold
- good +12V rail

7:39 TX-M
- there was an older TX line which was revived as TX-M in 2017
- 80+ Gold
- all Japanese capacitors (suggests better quality for PSUs)
- An 135mm rifle bearing fan is used to keep costs down, but on the plus side, this fan lasts longer than the plain sleeve bearing ones. 

9:21 RM
- 80+ Gold
- based on RMx 2018 design with some small changes to make it cheaper (eg. they used a cheaper fan)
- supports Modern Standby
- RM uses Teapo/Elite caps 

10:53 RMx
- 80+ Gold
- has capacitors in the cables
- RMx uses a CORSAIR-designed low-noise rifle bearing fan.
- RMx uses the NipponChemicon/Nichicon  caps 

11:44 HX
- basically the RMx but 80+ Platinum
- the HX750 is a frequent reviewer favorite

12:06 AX
- 80+ Titanium

13:18 SF
- 80+Gold and 80+ Platinum versions
- SFX power supply for SFF builds
- all Japanese capacitors (suggests better quality for PSUs)

14:23 RMi/HXi/AXi
