[SOLVED] Looking for 850W PSU recommendations for a Zen 3 + 3080 system

[Kxdri]

Hi everyone,

I’m building my first PC and I’ve been stuck on finalizing a PSU. I live in Canada and my main use case will be 1440p/4K gaming + streaming.

Build:
CPU: Planning for a Ryzen 5900X
CPU Cooler: Arctic Liquid Freezer II 280mm AIO
MOBO: MSI X570 Tomahawk
RAM: DDR4 3600 CL16
SSD: 1TB NVME SSD
GPU: RTX 3080 FTW3 U
Case: Phanteks P500A DRGB

I’m looking at the following:
- Corsair RM850x Gold (179.99CAD)

- Corsair HX850 Platinum (234.99CAD)

- Corsair AX850 Titanium (279.99CAD)

but I’m open to any suggestions/recommendations.


Thank you!

Any of those is a good choice. Excellent in fact.

Even the Seasonic Focus plus would be a fine choice if you need to shave a few bucks off.

I've heard great things about the Seasonic, but I'm willing to pitch in a few extra dollars for more silent performance. If you had to recommend one of the Corsairs, which would you go with?

 

[jonnyguru]

The RM850x is so much cheaper than the others, it's hard to justify the others.

 

[Darkbreeze]

Personally, if it were for ME, I think I'd shell out the extra money for the HX, but there is certainly nothing wrong with going with the RMx and saving a few bucks either considering how expensive these things are in your region. I sure hope you guys have like a 20.00 per hour minimum wage considering how much more expensive all types of hardware is there. It's the same way in Australia as well. Makes little sense. All this stuff has to be container shipped from China anyhow, doesn't seem like it would cost that much more in either of those countries than it does in the US and UK. I guess maybe tariffs and duties account for a lot of it maybe.

 

[Kxdri]

So you wouldn't go up to the AX, yeah?

 

[Darkbreeze]

No, I wouldn't. If I was going to go with a Titanium model, I'd go with (And DID) a Seasonic Prime Ultra Titanium, which was moderately less expensive than the AX and had exemplary reviews from all sources including Aris.

That's normally though, and right now, is NOT a "normal" market situation, as you've probably noticed over the last five months. You can thank a variety of reasons for that including Covid 19, increased US tariffs and tensions between the US and China.

Right now, for your market, that HX is pretty much the sweet spot if you want a high end unit without having to take out a loan. The AX and AXi models are not even available right now in your market from what I can see but availability changes rapidly these days.

 

[Kxdri]

Yeah, prices are really high due to the factors you've mentioned. Unfortunately, the Seasonic Prime Ultra Titanium is currently more expensive than the AX in Canada. Also, the AX is actually in stock on Amazon, its just not showing up on PCPartPicker.

Never thought I'd be so indecisive on a PSU of all parts, haha.

For the ax/hx i'd go with I model to be able to monitor consumption via USB, I remember it to be only 10 bucks more.

I'd rule out titanium entirely due to being overpriced over what it brings.

 

[Darkbreeze]

This shouldn't even be a question. The HX is hands down more than that build even needs. You gain nothing really by going with the AX except bragging rights.

You need RM-i/AX-i/HX-i for that, not AX/HX.

 

[Darkbreeze]

You need RM-i/AX-i/HX-i for that, not AX/HX.

That's what he said. "i" model.
