Go to PSU brands for 1000w or 1200w?

Steer away from the 2024 Corsair RMx series as there is something very wrong going on with them. There have been many failures of these new units.
Is this true? Where have you seen these reports? I was shortlisting a 1000W PSU and have the Corsair RM1000x ATX v3.1 on my shortlist so intrigued by your comment.

I've seen one failure on this forum and a couple on the Corsair subreddit just this week. Probably a very small fraction compared to units sold mind you but all appear to be the new version.
 
I've decided. Think I'll be getting the NZXT C1000/C1200. I believe issues were common with noise and early failures on on eof the C1200 models from a bit of reading last night. The C1200 model number was PA-2G1BB-UK but is now PA-2G2BB-UK.
Anyone know what NZXT are like for RMA? Also is this UK based?
 
The Antec HCG Pro Platinum 1000W is also worth considering as you get individually braided cables with it. This is a Seasonic built unit, and there is also an Antec rep on here @Ace Modder if you need any help with rma etc.

My basket at OcUK:

Total: £179.99 (includes delivery: £0.00)​

They were also in my short list as I had been reading the thread created regarding the Antec power supplies.
 

I've just fitted that PSU in my latest build based on a 9800x3d. The design is good but apart from stress testing the CPU using the igpu, I won't have a GPU until the 5090 are released so can't fully test it yet.

I'll be interested in hearing your thoughts once you are up and running with it properly.
 
Why, hello there :-)
Good morning again!
SOrry, Spent some time this morning reading up on the Antec products which are very interesting. I think the reviews may have swayed my decision again to one of them. I would imagine a 1000w supply would suffice for 99% of use cases, No overclocking etc.

Hi mate this is the one I'm looking at but thinking of getting the 1200w version hopefully futureproof a little longer
 
1000w is fine, but for sure the little difference going to the 1200w I think long term does make a lot of sense for users who go RTX3090/RTX4090/RTX5090 etc.

Who knows how much the RTX 6090 will need?

That is what I was also looking at but from other PSU calculators (utilising a 9900X3D and a 4090/5090) many are suggesting 850W or a 1000w PSU.

I went for the 1200w because I wasn't sure what draw a 5090 would take and like you, I thought it would be a bit more futureproof.
I believe some of the OC cards have recommended 1000w supplies but who knows what the next cards bring I suppose. We would need a new cable and adapter design.

Pretty much just said the same thing just as you posted.
Edit: I've no real plans to move onto the likes of a 4090/5090 for now but you never know what happens. I may get trigger happy at some point.

Always go a bit more than what you need I always say. If you are keeping something for 10 years and can afford it, go for it.

With an 80 plus platinum PSU it is going to be 90% efficient at 20% load, 92% at 50% load and 89% at 100% load. So if you are going 1200w, and your rig draws 600w when pushed/gaming - you're in the sweet spot. My GPU has been reviewed drawing 391w when gaming, call it 400w for ease. Imagine running on an 850w PSU. Half that capactity has now gone just to the GPU when gaming. How much does a 9800X3D use. Is it 120w? So we're at a potential ~520w and haven't included other bits and bobs from a rig sucking the juice. A 50% load in this example, would ideally need a 1000w psu, for peak efficiency. I just personally don't like the idea of running near or at full load (even though you can). Your just gonna be generating unneccesary heat, noise and waste energy. If it isn't a platinum rated PSU, say gold, the efficiency is 2-3% less. For an 850w PSU you are wasting about 110w. I think I'm right in saying that. Someone will no doubt call me out lol.

Thanks.

Oh definitely, at least if I over spec now, that should cover at a minimum of two GPU upgrades (I don't tend to upgrade too often).
I have no idea what my current system wattage is but could probably find the ballpark if it were to run everything peak load.
I guess having further headroom leaves plenty options.
