Which PSU would be better?

[Tom80765412]

 

So I need to upgrade my PSU and I have only these 4 options available where I am from.

There are probably better PSUs then these but I can only choose one out of these 4.

So based on my current specs, which one should I go for?

 

ASUS ROG Strix 1000W Gold ROG

https://rog.asus.com/power-supply-units/rog-strix/rog-strix-1000g-model/

 

OR

 

Corsair RMx Series™ RM850x — 850 Watt 80 PLUS® Gold Certified Fully Modular PSU

https://www.corsair.com/us/en/Categories/Products/Power-Supply-Units/Power-Supply-Units-Advanced/RMx-Series/p/CP-9020180-NA

You can only choose those 4? What country are you buying in? 1Kw is overkill for your specs and Gigabyte has had issues with their psus (if anyone can say otherwise feel free to chime in, since i cant remember the specific model). So it seems like the only choice is the rmx, though you really only need a 750 watt psu

Corsair RMx

Asus ROG Strix

Pick either the RMx or Strix depending on price. You don't need an 850-1000W power supply for an i5 12400 and RTX 3070. See if the 750W models are available, that's still way more than you need with that system.

The notable issues they had were with the GP-PGM models... The UD-GM models OP listed are actually based on the same design but the major flaws have been fixed. Gigabyte rebranded them under a different model name to disassociate them from the bad publicity, but at least you now know that the UD-GM ones are the fixed ones. There were some other minor changes they made, they claim it's an ATX 3.0 compatible power supply but when it was tested it failed to meet some of the requirements... They're much less likely to explode now but still not worth recommending.

 

Edit: I might have got that thing about ATX 3.0 wrong. I thought they marketed it as an ATX 3.0 power supply but I just looked and there's no mention of it on the product page and the specification page states v2.31. Either they've since removed it or I'm remembering it wrong.

1 kw might be overkill but ignoring that for a minute and  comparing rm 850 with it. Which one will perform better? Which one will last longer? Which one has better components/features?

[PineyCreek]

ASUS hit or miss.  They're spread too thin but likely their PSUs are all rebadged? Their fingers are in way too many pies...but I admit I don't know details on ASUS's foray into PSUs.

 

I've been using Corsairs for years, never an issue.  My own RM850x is still going strong.

 

Wouldn't trust a Gigabyte supply with a 50ft pole after their most recent PSU screw-up/fire hazard.  Wouldn't trust Gigabyte anyways after buying their flagship MB 10 years ago and their support figuratively screwed me. No Gigabyte products for me personally, ever.

They are available but mostly of Gigabytes or other brands  bronze ones.

The Asus Strix power supplies are based on the Seasonic Focus GX, with a few minor design changes.

Oh really? Well Seasonic's been quite reliable as well.  ASUS made a good partner/rebadge decision, sounds like.

Did they also copy the 12v rail issues?

I'd say the rm 850 would be the better choice if I had to pick between the 2

Lets say I can easily get ASUS one right now as compared to RM850x... Should I go for ASUS one?

Its like to get RM850x I will have to "travel" to other city. But ASUS is available nearby....

[Han2K]

RMx is the obvious choice, but if you can spend a little more, don't think twice and get an HX series.

In that case get the Asus Strix. It's a good power supply. It's wayyyy overkill for what you need, but if there's nothing else available...

The issues with shutting down with high end GPUs? I don't believe so, and afaik that's now fixed on Seasonic units as well.

Yeah...even so, I'd go for the Corsair, and I agree you don't need a 1KW PSU, but if ASUS is Seasonic that'd be fine.  I'd also compare the warranties first as well between the PSUs, just in case.

Both have one year local warranty.

...wow, I apologize for this observation but you get crap warranties wherever you are.  The Corsair has a 10 year warranty in the US...well, if you're not abusing it, PSUs are like storage...if it's going to fail, it'll be out of the box or within the first couple weeks of regular usage most likely.

 

Maybe write your local government official.

 

Oh yeah, maybe it's my own personal neuroses, but test the PSU before connecting it to any hardware.  Basic stuff, just to power it on and the like.  Make sure the magic smoke doesn't escape immediately and sparks aren't flying.

That would just be the warranty offered by the store. Both the RMx and Asus Strix offer 10 year warranty, you would go through the manufacturer customer support to make a claim through the warranty.

... Unless you're buying a used/refurbished power supply, then the warranty will be different.

Well, Seasonic Focus GX is nothing better than mediocore with the quality of the fan, analog fancontrol, 40 degree rating and thin PCI-e cables. Asus made the PSU even worse by replacing the heatsinks inside the PSU with very large ones that prevent airflow on some components. So in my opinion the Asus is not a very good choice if the Corsair RMx is available and comparable priced.

It entirely depends on the model. What model is it?

There are different models but only cougar has burn/damage warranty available of 3 years.

I'm not familiar with Cougar's warranty terms so I'm not sure exactly what that is. I would assume that any power supply that catches fire would be covered under normal warranty, though I would prefer a PSU that doesn't catch fire.

 

I'm not super familiar with Cougar's lineup these days. The GX-F would probably be most comparable to the other PSUs you were looking at, but somebody with more knowledge of Cougar's PSUs could probably give better recommendation.

Warranty rules are a bit different here sadly...

 

 

So the shop I visited showed me these 3 variants of Cougar which had good warranty but I wasn't sure about Cougar PSUs at that time.

 

Cougar GEX1050 80Plus Gold 1050W PSU,

Cougar GEX850 Gold Full Modular PSU,

Cougar GEX750 Gold PSU

None of these are particularly great compared to, say, RMx

Cougar GEX is budget Gold, comparable to Cooler master MWE Gold V2. It uses the same platfrom from XHY.
