Seasonic Prime TX-850W vs 1000W PSU for 6800 XT

[maremp]

Yeah the answer is obvious, get the beefier one, titanium is very efficient anyway. But the question is around the price difference.

 

Seems like the amazon had a deal, I got the TX-850W for around 190€ (yes I'm sure it's TX and not the cheaper PX), while the regular price is 220€. And the 1000W model is 308€ atm, so there's a huge price gap for the extra 150W which I don't see using up.

 

Second part of the upgrade I plan to do in the following months is the RX 6800 XT (if the prices go down to a more sane level), which list min 750W PSU. Currently I have RX 5700 XT.

 

But after I was looking at the PSU tier list, I got some doubts when I saw some asterisks around the Prime TX <=850W models:

Quote

Seasonic PRIME based units experience shutdowns with RTX3080/3090 (and possibly RX6900 XT) GPUs, especially ones with unlocked power limit like FE and ASUS Strix. It is recommended, if going with such units, to overprovision wattage

 

For the CPU, I'm currently on i7-6700K (91W TDP), but I was thinking about upgrading to 5800x or 5900x (both list 105W TDP), but I might hold out for the next gen. There's nothing else with a significant power draw in the system.

 

Should I be worried about potential issues with the TX-850?

Why so much power? I ran a 5800x and now a 12900k and 6800xt on the Corsair SF600.

Yeah I'd say an 850W would be heaps. It's a 300W card yeah? Even if it ran up to 600W you should still have room with an 850W

No, get another brand. Although a 6800XT shouldn't make a Prime TX 850/1000w to shut down, 6900XT and RTX 3080 (T)i/3090 will. There are better units for a comparable or even lower price. Corsair HX850 V2 and be quiet! Dark Power 12 850w for example.

Better in what regard? I'm not trying to disregard your comment, just trying to gather more info. I always considered Seasonic to be top-of-the-line brand. When I was starting by build in 2016 I recall reading a lot of positive reviews. And even when I've looked now, the Prime PX/TX units got stellar reviews.

 

Corsair is based on the Seasonic, no? Interesting that they don't have this issue.

 

I did consider the Dark power 12 but it was more expensive (230 vs 190€, +21%).

I literally gasped when I read this sentence. Expect an army of angry PSU experts to flood this thread...

That's what a lot of people think but it's not true. A lot of other OEMs can make better PSUs.

Corsair HX for example. A CWT platform with no issues at all. Better fan, better fancontrol, better electronics, better connectors,  real 50 degree rating.

No. Non of the current Corsair PSUs is based on Seasonic. AX Titanium was but is continued because of issues.

No. Absolutely not.

Neither really. EVGA G6 and Corsair RM-x are cheaper. The former is actually made by Seasonic too, so it's not like you 'lose' anything (even if i consider RM-x a bit better actually), better than pretty much anything else made by Seasonic currently. Seasonic Prime are overpriced and problematic. 850W is enough, 750W is too actually, but 1kW may make sense if you want to overprovision for the next-gen stuff, although that may not actually help, nothing is known about whether current PSUs would be able to handle even larger transients than Ampere currently have.

Those tend to bring in more suggestions, I like that

My bad, must have been from really old reviews then, or am I just misremembering things? I have to go back and update my knowledge. I'm sad that jonnyguru.com is offline, it was my primary source of reviews when I was picking the PSU in 2016.

So considering that I've already ordered the Seasonic one before checking this (yeah, stupid of me), should I consider returning the Seasonic one and get the HX instead?

 

But also if there are issues with it, I would be able to take advantage of their 12y warranty, no?

Not sure if that's a fair comparison, I think those target a lower price bracket hand have gold rating compared to the platinum of HX or titanium of Seasonic TX. I understand the 80+ rating does not mean much, but when comparing it in reputable brands, I believe it requires some level of build quality to achieve such results.

 

Edit: Also, I'm not after the best bang for the buck here. I can afford to spend a bit more on something that's for sure going to last me for some time. I know platinum/titanium is not going to bring me much savings over the gold (I did the math), but there's just some peace in my mind with the more premium build quality. Or I am just influenced by all of the reviewers to think the premium thing is way better.

It's not difficult to make a Platinum/Titanium rated PSU with bad protections, bad cables and connectors, bad fan, bad fancontrol etc.

 

Also take notice of the temperature rating. Seasonic Prime is rated at 40 degrees at 100% load, Corsair HX 50 degrees. Higher temperature rating needs better quality.

Yes of course, I did read about the shitty PSUs that are 80+ gold, or even switch-and-baited the customers. But we're not talking about X company from China, I believe Seasonic is not that.

Good point, I did not consider this, thanks for highlighting it.

Well, fair enough, there are of course more advanced and 'better' options than those i've mentioned above, and if you're ready to pay extra for them - why not, but personally i don't really see the point as those 80+ Gold options i've mentioned above are already very good. Anyway, have look at Corsair HX, Super Flower Leadex Platinum SE / EVGA P2 and maybe be quiet! Dark Power Pro 12 but it's too expensive IMO. There's also EVGA P6 but it can't really offer anything that EVGA G6 can't and for some reason is actually less quiet.
