Recommend me a PSU replacement

snips86x · 3 Apr 2021 at 11:51

My HX850+ is starting to show its age now, I applied an overclock on my GPU and after about 20 mins the PC switched off. Removing the overclock stopped this happening. PSU is probably 8-10 years old now so I think its time to get a replacement.

What would you suggest for 5900x & 6900xt? Happy to go to about £200 for a decent unit.

I have been looking at the following but unsure if a 1kw might be a better solution - or it might just be the age of my current one which is making me think 1kw would be better.

I would look up to see what 850w units handle the Transient Spikes the 3080/90 and the 6900xt (AFAIK) cause to peak at 1000w

AFAIK the Corsair will be fine.

I must admit, I haven't looked into the power spikes on the 6900xt but that would explain a lot. I know I can monitor the PSU usage using the Corsair units, which was why I considered it. However, the price is mostly branding.

And who actual manufactures it, I know not all Corsairs are Seasonic as it depends on the series.

I have a AX1600i which is about as good as you can get and going by market now it was not overkill when I got it 2nd hand (but new/sealed for a good price).

Reference 6900 XT spikes little below 500W in games.

Though non-reference models no doubt have higher spikes and also overclocking would fast increase power draw.

Oh wow, that's like the perfect unit

Thanks, might have just found my replacement.

The RMX series is great, but don't write off the 2018 model. The 2021 release is significantly more expensive, and the 2018 is still being sold as a slightly cheaper alternative. It's still a truly brilliant supply.

They don't make anything for Corsair these days. The ones that they did make are no longer in production.

I think CWT are behind most, if not all of Corsair's current gold rated units.

I thought Superflower supplied corsair?

They're my go to PSU supplier, if it was actually avalible I'd go for the Leadex III or Leadex Titanium.

Not to my knowledge, I know Superflower used to cover a number of EVGA units. I think Great Wall are Corsair's TX-M OEM, but that's the only exception I'm aware of.

CWT make some fantastic PSU's regardless.

Are the EVGA SuperNOVA G1+ 1000 units still worth a look, I know they're prob 4 years old now though.

If I was given the choice now I'd get either:

OR

If I'm buying something right now on a "budget" then maybe:

Thanks for the input. I'd prefer to buy sooner rather than later, especially if a small overclock on my GPU is causing my PSU to cut out. It's been a good solid unit for 8 years, probably time to be replaced now.

That SuperFlower is needlessly expensive, and you will not save enough money over a Gold rated unit to justify the extra cost. The Leadex III Gold 850W for example is £102 cheaper. The Silverstone psu is SFX so not much good if you have an ATX case.

Thanks Lee. I haven't purchased yet as I'd come to the same conclusion. Kinda hoping stock picks up soon as well.
