Question Troubles after switching to a RX590?

[firebirdude]

I ran a Radeon R9 280 video card for a few years in my PC. No problems. I decided to upgrade my wife's video card and bought her a 5700XT. I took her old RX590 and figured it would be a small step up for me. So all same PC, just swapped in the RX590.

It's crashing under load. The entire PC reboots. I even pegged the fan curve at 100% at all temps (and I heard the fans ramp way up), but it still crashes the entire computer within about 1 minute of playing a game. I can websurf all day.

Well my power supply doesn't have an 8-pin video card connection. I bought an adapter that allows the connection of two 6-pin PCI-E power connections into one 8-pin that would then go to the card. So in theory, I'd have power capacity of 225W, no? 75W from the PCI-E slot itself, then 75W from each 6-pin PCI-E plug? This should be sufficient, no? If no.... then WTF do they even make the adapter?! Let alone all the versions I past up with only one 6-pin input!

As a heads up, I tried one version of driver backward. Same issues. Also keep in mind this card worked great in her computer for over a year.

This is untrue.

Edit: It could be written, "an unsafe/less-safe PSU will only use a single rail".

Well, that depends on the output rating. A 1200W PSU with 1 rail would not be the best setup from a safety standpoint. A 500W PSU with many 12V rails is going to have trouble running anything but a basic GPU because no one rail will provide enough current.

Damn. Well hopefully this one lasts lol. Decent reviews.

A 500W PSU with many 12V rails is going to have trouble running anything but a basic GPU because no one rail will provide enough current.

But that would be a poorly-designed multi-rail PSU. For example, imagine a PSU with 50A total on the +12V coming from the PSU, with three "rails", each with 20A or 25A limiters. That would be enough, to power beefy GPUs, without worrying about melting wires. (Well, I don't know if my numbers are actually right, I kind of pulled them out of thin air.)

But the multiple rails, don't all have to be strict sub-divisions of the "main rail". As long as the current limiters on each rail aren't set too low (like 14A + 15A, like I've seen on some really crappy low-end 500W PSUs), then things should be OK.

There do exist poor-quality multi-rail PSUs, to be sure, as well as poor-quality single-rail supplies. One or the other option, is not really any inherent badge of quality, AFAIK.

Yeah, "decent" PSUs right now, are like $80-100 and up, nearly twice what they cost last BF.

Besides the BF sales last year, the market was coming off of the GPU mining boom, so there was an over-supply of really solid PSUs at the high-end, so they were being discounted heavily, and then now, we have tariffs of like 10% or maybe soon if not already, 15% or 25%.

I WISH that those EVGA G1+ 650W/750W modular PSUs were still $60-75 on sale, I'd snag a whole bunch of them.

I doubt you're pulling anywhere near 550w with a RX590 GPU (unless you are running an overclocked Threadripper 3970X as your CPU).

Just as an update, I purchased a BStock EVGA 850 GQ, 80+ GOLD 850W directly from EVGA. Popped it in and she's working like a champ now.

Good to hear!

Late to the party, but as the guys already figured out, it was the PSU.
550W is plenty for a RX 590, but only if the PSU is single rail.
Older PSUs with multi-rails split the rails one dedicated to the CPU, the other rails for everything else.

That X-clio, being 3 rails, it is very likely one for CPU, one for GPU, one for everything else.
18A is NOT enough for an RX590.

Enjoy the upgrade!

I might have to do the same, for a friend of mine, that built a Ryzen / RX 570 PC last year (around May 2019). He's suddenly getting BSODs. I keep telling him, stay off of those "movie sites", they're probably either: 1) mining in the background, which actually shouldn't cause a BSOD unless his cooling or power isn't up to snuff, or 2) the sites are just plain trying to exploit the system (drop some shellcode onto the filesystem, for when it reboots).

It might just be software, too, it's a really old Win7 64-bit installation, that was upgraded to Win10, at the same time, switched hardware platforms from AM2+ to AM4. Might be some cruft in there.

GSKill RAM (basically new), Ryzen 1200 (new), Asus ROG STRIX RX 570 (new), Gigabyte B350 or X370 mobo, either open-box or refurb (but worked fine for 8 months???), Rosewill 80Plus Gold PSU (new). I haven't been having good luck with any of the semi-higher-end "gaming" Rosewill PSUs, they seem to have issues after around a year. Even had a Capstone with 5-year warranty and Jpn caps crap out on me on another friend's rig after a year.

Maybe I'll go for a B-stock EVGA PSU too, and see how it goes.
