keep Corsair HX1000 or new RM1000x (2021)

[pinkua]

Hello,

 

I have been using a Corsair HX1000 for 2~3 years now and today my friend gave me a free new RM1000x (2021).

I wonder which one is better.

I have no idea if I should swap PSU just because I got a new PSU from a friend.

So here I am asking for help and recommendations.

 

Spec

 

CPU:5900x

Motherboard:B550 Unify-x

GPU:RTX 3080TI FTW ultra

Ram:32gb 1800 lc14

PSU:HX1000

SSD:SAMSUNG NVME 2TB

 

Thank you!

The HX is better since it is multi rail, although in general they are both high quality PSUs.

hmmm so i should just keep HX over RM1000x even it's a new one right? 

Also if you do not mind . What is the difference between multi rail and single rail. I heard about it alot but I was always too lazy to learn about it. loool

Multi rail has more OCP, the additional OCP chips on each rail technically make multi-rail PSUs safer than single-rail models, but the vast majority of PSUs have short circuit protection and other safety features that do just as good a job at preventing shorts and minimizing fire risk. 

OCP is over current protection, basically if anything goes wrong, your PSU will protect the rest of the components.

HX are damn solid units, unless it was like 7-8 years old I wouldn't bother replacing it.

One OCP rail (basically a fuse to trip) for the whole PSU, vs one for every cable out of the PSU but lower individual ratings before they trip, that's my understanding of it. Single rail is better if you're OCing or using really power hungry/power-spiky hardware, multi is technically safer but will trip if you have a GPU or something absolutely chug power. For everyone who isn't doing XOC or using really monstrous workstation stuff, the difference is basically nil assuming both are quality units with appropriate wattage for your hardware.

you guys are the best lool . i fully understood what is single and multi rail is, thank you for the details .

 

I forgot to say HX is a refurbished PSU since I had to RMA 3 years ago. because one of my PCIE cables was burnt, so I just RMA the PSU just in case.

So I've been using this refurbished HX1000 for 2 years now .

and that is why i thought maybe since i got a new RMX psu for free i should change the psu.

 

But it looks like even its refurbished, based on what you guys told me , i should just keep HX  am i right ?

Yep! Until PSUs are 8-10ish they usually aren't even at all suspect, and plenty of folks have ones older than that still kicking. I'd hold on to the RMx for a second build or just a backup if you ever do have issues. Even for basic troubleshooting, being able to rule out the PSU as a possible problem by swapping in another is super nice.
