PSU recommendation

Hi

I'm having intermittent reboot issues on my PC and I have a bit of a feeling it's power related. I have a Corsair TX 850w PSU that I bought back in the crazy days of 2009, so reckon that's probably done enough hours.

What would be the recommendation for something very quiet but reliable, and likely to survive the next couple of upgrades.

Case is a Darkbase Pro 900, currently on a Ryzen 5 3600x / B450 platform although tempted to throw in a 5900x as an upgrade, with a Nvidia RTX 3070. Need a fair few SATA connectors that can string around the case as they power 4 drives, optical drive and the bling-bling case lights.

Think that's about it that's relevant but let me know if there's anything I've missed.

Not interested in splashing top dollar just for the sake of it but can spend whatever is required to get the job done properly.

Thanks all
 
Thanks for that.

With PC power requirements only heading in one direction at the moment, I'd be inclined to go for the higher wattage of option three, not to mention the future proofing of atx3.

Might it even be worth getting the 1200w version?

I assume the latest iterations will still be backwards compatible with my current mobo and GPU connections?

Edit: someone has posted a product review saying the cables are quite short. My case is very tall so likely to be an issue.

Any other recommendations?

In my opinion: no. I don't think it is practical for the power requirements to keep going up, it makes the cards too large and the cases can have trouble getting rid of the heat.

If you stay with AMD in the future, then the 7800X3D (or equivalent), has pretty low power consumption, so you'd only be looking at a high draw high-end card, but even then undervolting is very common now, so many high-end cards are only being run around the 200-300 watts range.

Is there an efficiency or noise-level benefit in running a bigger PSU at lower load percentages?

Will do some more research on cable length vs what I need in my case. The Thermaltake certainly comes with a lot of connectors but perhaps a bit short in length. I see there's an ASUS TUF and MSI MPG in a similar price bracket, plus a Coolmaster (although not a brand I would normally rush towards) if those might be worth a look.

Seems best to avoid Corsair as they don't have the proper new connector.

Or is this a case of wait a few months as everything is brand new out there?
 
Well thanks to both of you - I'll take it away and do a bit more research and then hit the buy button on something.

Lower noise: yes, this can be a benefit of a PSU that is overspec, as a secondary benefit of the lower temps.

Low noise is quite important so will keep that in mind.

Yeah, I already linked an anandtech review of the PCIE5 A850G/A1000G, they look like decent PSUs. Anandtech also have a review of the new TUF: here.

Oops, skipped over that link the first time. Thanks for sharing - will give both of the reviews a read.

I know nothing about the Coolermaster.

I'll Scratch that off the list to save adding to the confusion. I think I'd need serious convincing to move away from the more trusted brands!

I think they know what they're doing at this point, but it is your call.

I don't know which PSUs are shipping with the revised connector (12v-2x6), but that would definitely influence my choice if I planned to buy a 40/50 series in the future.

I've been looking at the images on the OC website to see which have the physical connector with the extra row of four smaller pins. It seems the Corsairs don't have those (and the buyer reviews also note this) and that they're meeting that relevant standard by being able to deliver the requisite 600w down the normal PCIe cables (I could be talking out the wrong hole here of course!). Completely agree there's no point handing over money for something obviously missing a connector that is likely to be used in the future, hence ruling the Corsair out.

This is the RM1000x Shift, for example:

As far as I know, the issues with the 12VHPWR connector are only on the device end. I haven't seen any reports of burning connectors on the PSU end, so I don't think the SHIFT's arrangement is a problem (at least, not in that regard).

I don't know if Corsair are using the revised 12v-2x6 connector on the device end and that's the part which would influence my decision, more than what they're doing on the PSU end.

I guess you're right - there wouldn't be anything being sold by the likes of Corsair that isn't fit for purpose. But as I understand it the additional 4 pins are to allow the GPU to communicate back to the PSU so in theory, if not in real-world usage, the simple cable implementation isn't as 'smart'. Then again, what's to say the additional 4 pins are actually connected to anything in the PSU - they could be purely decorative to fool people like me into thinking their product is superior.

I think the new connector did well in testing, regardless of the sense pins, there's an article here which includes a link to the video. But, yeah, I don't know how much the sense pins are used in reality.

Ah, I now see what you mean about the cable and that there are two iterations which look pretty identical.

I'm now looking at the FSP hydro ptm X pro, either 1000w or 1200w. Not sure I can justify the cost of the ti pro.

Ahh, oops, I didn't notice that (like I said, I ignore FSP because they're nearly impossible to buy here :D ).

I think I'm going to take a punt on it. Reviews very well and only consistent criticism seems to be lack of availability, comes with a 10 year warranty and seems to have a high number of connectors with cables at decent lengths.
