Is a Seasonic Focus GX 850W good enough for my system?

both PSU are having the same issue? It may be more of a mobo issue. You basically need to test each component individually.

Mobo issue is also out of the question. This happened on both my old Gigabyte B550 Aorus Pro, and now it happens on my ROG Strix B550-F.

The only thing that could be the issue is the PSU.

how can it be the PSU if both PSUs are having this issue? The CX series is extremely common and this issue would be all over tech forums if this was a design issue.

Feel free to let me know what the issue is then as I'm completely stumped. I tried everything except buying a new PSU.

I'm not saying it definitely isn't the PSU but rather it would be extremely odd. Same SSD and RAM in both mobo set ups? Is the RAM OC? What happens when you set windows power and sleep to never?

Disable the sleep function...

Glaceon · Nov 3, 2020

Same SSDs, different RAM from previous Gigabyte build. Added a NVMe to this build. PC still reboots with only NVMe plugged in. Not the drives.

RAM is not OCd, only D.O.C.P. is enabled. Still happens without the D.O.C.P. profile.

I change the power and sleep to never by default, but it still happens with them on.

And what sleep function?

EarthDog · Nov 3, 2020

C-states. Disable C-states if you haven't.

You mention you 'had an intel board and cpu before that'... did you reinstall windows fresh or clone it over?

Glaceon · Nov 3, 2020

... I have disabled C-states, that's the only way I can keep this system running without having it reboot. Enabling them brings back the shutdowns. But disabling them limits my CPU's boosting ability and idle power usage.

Yes, I always do fresh reinstalls on new boards.

Did you update the BIOS? From reading some posts around the web you are not the only one having this issue.

Ryzen and disabling C6 C-state, the curse of C6

Seems like all the solutions I tried to stabilize Ryzen by disabling C-State C6 locks the CPU at base clocks. Apparently people affected by the Curse of C6 have had no official definite fix in the kernel or from AMD themselves since Ryzen 1st gen… I want to gather horror stories here because...

BIOS is latest (1202), AGESA 1.1.0.0 Patch B. Latest AMD chipset drivers. Ryzen Balanced power plan.

Am I just doomed to keep C-states disabled? Most people who build Ryzen rigs don't even need to mess with the BIOS apart from XMP, and it works for them just fine. No idea what's going on.

It's definitely frustrating, you can obviously try the seasonic PSU it just may not be the answer to your problem.

Glaceon · Nov 3, 2020

My CPU seems to be boosting to 4.6 single thread with PBO disabled in the BIOS and C-states disabled. It also downclocks cores.

It ALSO doesn't seem to be shutting down in the same idle test where it shut down before.

I guess we're good? Just keep PBO and C-states disabled in the BIOS and it works?

I have no idea if XFR/PB2 are behaving as they should right now so if someone could enlighten me on that that'd be great.

Also... my cores are now sleeping in Ryzen Master. With C-States disabled??? How? Is this supposed to happen?

Rei · Nov 3, 2020

I'm confused here... OP seems to know a bit more about computers, has a good rig & even prolly capable of overclocking... BUTT?!?!?... Lacks much knowledge on PSU power requirements among other PSU related matters? Maybe it's just me & correct me if I'm wrong, I just find that notion to be a bit... unbalanced...

jesdals · Nov 3, 2020

Before bying a new psu, perhaps a nother look at your memory - try to look up with typhoon burner what kind of modules they are. Enable XMP profile, at try to set dram voltage to e.g. 1.4v

Glaceon · Nov 3, 2020

My memory is fine, I tested with different modules and it does the same thing. It's 2x16GB G.Skill Ripjaws V 3600 CL16.

Rei, I actually don't know anything, I just regurgitate it from the internet.
If I knew what I was doing I wouldn't be here.

I'm still looking for answers to my last reply.

jesdals · Nov 3, 2020

Did you enable XMP on the other set? 2x16GB G.Skill Ripjaws V 3600 CL16 can be samsung, hynix, micron etc....

Yes I have. It's Hynix with 16-19-19-39 timings. 1.35V.

jesdals · Nov 3, 2020

I would give XMP and 1.4 a go, enable geardown mode setting in the advanced settings for mem and if you can find a eco mode in bios try to disable it. In windows make sure you have the latest AMD chipset driver, and enable ryszen powerplan in windows powermanagement settings. Try set the later to always on

@Glaceon
the reboots are from bios, can be combo of bios (version)/ram/mb.

how did you update the bios?
under win/in bios, or with dos flash?
some boards (at least on the Gb i had) dont delete properly and you have left overs.
you might have to use dos to update, with flag to delete (previous) bios before flashing update (even if its the same version).

load defaults, dont enable xmp, just set clocks and voltage manually, disable gear/power down
BUT leave EVERYTHING else on auto (neither dis/enabled).

for the psu:
you wanna get your avg load to be about 50% of the psu max output.
this gets you the best efficiency when it consumes "the most" (vs idle etc).
so a 750 should be better (i have about 2-300w avg and 5-600w under "full" gaming load running 3700x (pbo) and oced 2080S).

i wouldnt get a focus series, unless its made 2019 or after, Prime (gold and up) are fine.
PSU tier list
i would get the Corsair RM750x or Thermaltake GF1 750w (almost as good, but cheaper), or bequiet Straight Power 750w.
the bequiet seems to get a bit "noisy" when above 350w load, but you shouldnt reach that (i dont care about warranty past seller return, and just replaced the fan with a silent one

)

Corsair
Tt
bequiet

X71200 · Nov 3, 2020

Ain't nothing wrong with the BETTER Focus units if PSU replacement is going to be at it, whether it be necessary or unnecessary. The Bequiets you mentioned are FSP units which are not bad but have Teapo caps and inferior soldering across the board. If anything, I'd get a Focus based unit over that (and I did, twice

).

How are reboots in windows caused by the BIOS?

Glaceon · Nov 3, 2020

I updated the BIOS in the BIOS itself. I already tried inputting manual RAM settings and leaving everything on Auto, didn't help.

I'll hold off from buying a PSU for now. I'll just use my combo of PBO off + C-states off, seems to work fine and CPU is boosting as it should

John Naylor · Nov 3, 2020

Replacing CX series PU ... good idea.

Picking a GX 850 is a bit more than ya need, but if proce is right, not a bad thing

I have a 1250 because it was cheaper than a 1050 ... system draw is 780 watts under stress test and the 850 was just too close.

A 620 / 650 would work here (Guru3D):

Here is our power supply recommendation:

GeForce RTX 2070 - On your average system we recommend a 550~600 Watt power supply unit.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina. Also, at half the PSU load (50% usage) your PSU is the most energy efficient.

But if we say the recommendation is for a 500 watt load, for up to moderate overclocking, Id want +25 % or 625 watter ... for heavy overclocking I'd want more maybe a 750.

There's also noise and heat .... PSUs are most efficient at 50% which means the close you get to 50% load, the closer you are to reducing noise. At 50%, your PSU fans might not even go on.

Theres alsi a GX 850 Prime and GX-850 Focus Gold ... I can;t see that you will ever get a return on the $50+ cost premium for the Prime.

On newegg, the Focus Gold Full Modular GX 850 is $179
On newegg, the Focus Gold Full Modular GX 750 is $169
On newegg, the Focus Gold GX 650 Full Modular is $124

On newegg, the Focus GoldSemi Modular GX 850 is $136
On newegg, the Focus Gold Semi Modular GX 750 is $110
On newegg, the Focus Gold GX 650 Semi Modular is $100

I see the 750 Semi Modular as the best buy for the buck ... Unless you are hand sleeving your PSI canles, full modular does abasolute squat for you. It's not as if you can build a system without using any of the hardwired cables. So if you must use all of the hardwired cables anyway, and it still gives yu th option of leaving the other cables in the bag, what's the point of having them modular ? All full modular does for you if not hand sleeving is introduce a potential failure point and add a small hit to efficiency.

X71200 · Nov 3, 2020

Look at anything that is not named Focus but is Focus lol, like Antec, Phanteks etc. All the same unit inside some even better from the outside looks-wise. Cheaper.

Waldorf · Nov 3, 2020

@X71200
your right, it should be dark power pro, not straight power.
just didnt like that some of the focus units in similar price range to Corsait/Tt werent getting the same (top) ratings,
dont remember what it was (ripple/transient etc), but enough for me to look at the other 2 brands.

@EarthDog
should have kept reading a bit more:
... some boards (at least on the Gb i had) dont delete properly and you have left overs.
you might have to use dos to update, with flag to delete (previous) bios before flashing update (even if its the same version)...

i had multiple ryzen rigs build and was able to exclude any other hw, and after spending some time,
found others have issues too (not just me or Gb boards), but i knew the board was fine,
as all tests/benches from memtest to prime/occt ran fine, same for light/med/full load no matter if gaming,
only happened under idle/low load (browsing/office).

having flashed the bios under dos, setting flag to delete bios/update both chips fixed it.
runs now for almost +3 month without sudden reboot, before avg of 1 week, max 3.

@Glaceon
i asked because updating the bios (under bios and not running dos) might be the issue.
at least worth a try, as i thought you wanted to try to fix it...

@John Naylor
the CX (non M) series are great units, unlike the modular ones.

all Focus units you listed (full modular) cost more than the corsair/thermaltake,
not sure how that makes sense, especially since the corsair is one of the best gold units.
