New Psu for 7800x3d and rtx 4070 options advice.

[Garra]

Hi All ,

I hope everyone is doing well!

I need to buy a new PSU for my system :

Cpu: Ryzen 7 7800x3d

Mobo: Asus rog b650e-f

Ram: Kingston beast 6000mhz cl36 32gb

Gpu: Gigabyte 4070

From where I'm from , i don't have to many options and the options that i have are pretty expensive , the last 5 years i used a Seasonic SSR-750FX Plus GOLD , that seems to be failing because im having to much stuttering on games. After investigating and trying everything that i saw at the internet seems that the PSU is the problem ( because all other things cpu , mobo ,etc are new) .

From what i read a 750w PSU will be sufficient for my build, these are the options that i have :

1) SEASONIC FOCUS GX-850W = 189USD
2) GIGABYTE 750W GP-AP750GM = 173 USD
3) Asus TUF-GAMING-750B = 170 USD
4) Cooler Master MWE GOLD 850 - V2 = 190 USD

What do you guy think will be the best option ? I dont know much about PSU but from what i read may be the Seasonic or the Cooler Master ?

Thank you very much in advance!

Seasonic Vertex 750w Gold, 3.0 and 10 year warranty for $169 if youre in the US.

Your system can live with a 430 W PSU no problem given it's a high quality PSU.

Any Corsair RM750 PSUs around? Must be a tad cheaper than those and still be an overkill.

Im not from the US , that one here cost 250 USD , seems to much for me for a PSU.

Those are the options that i have from what im willing to pay , i tried to find a corsair because i read they were very good but no luck , the ones that are in stock here cost around 300 - 400 USD

just spend the extra 30 bucks and get yourself a decent 1KW PSU and you never have to bother about "is my PSU fine" for the next decade.

Of the four power supplies listed I would go with the SEASONIC FOCUS GX-850W.

Edit: Your current Seasonic SSR-750FX Plus GOLD has a 10 year warranty. RMA the unit.

I personally would go with Seasonic for Corsair. Since EVGA seems to be closing it doors on everything now.

I always go with 850W, its a power curve on the efficiency, so I try to keep my system usage in the middle.
I would look for the one with a decent price point and the highest 12V amps rating. That way if the next gen devices spike, or you swith to a much higher wattage CPU/GPU later, you dont have to replace the PSU with it.

I bought this years ago. Have had no reason to replace it.

The Seasonic is the superior unit of the four you listed.

Well have you seen anything similar anywhere else? I doubt that PSU can go bad this quickly, why not try a few (other) stress tests or see if it could be a driver/OS issue? And even if it is a PSU issue it should be covered under warranty.

 

[Vya Domus]

An insufficient/bad PSU does not cause stuttering in games.

If that's why you are replacing it you are more than likely wasting your money and time.

I have read in a few forums the PSU being bad and sending wrong voltages . I tried almost everything in terms of stress tests and software , that stuttering issue is coming from my old setup , i had a 8700k which i updated because i thought that the issue was because the cpu was doing bottlenecking with a 4070. This weekend i changed everything , new cpu,mobo ,ram , etc less my PSU and the issue is still occurring that's why at the end the issue could be my PSU , if isn't that i dont now , i re installed windows completely on a new system

Isnt what i want obviously , but i have tried everything in terms of software , i watched like 50 episodes of solutions at youtube and read every forum that i found. And going to the fact that the only part of my pc thats not new is the PSU , everything points to that be the issue

The 850w focus is probably going to be your best option if you are replacing the PSU then.

Fine, I am just telling you don't be surprised if that doesn't fix your problem. When the PSU is causing problems you get system crashes, not stuttering, that's more than likely down to the games/software/something isn't configured right.

And this was with your previous OS installation? The PSU could be failing but the stutters don't prove anything wrt it ~ I can think of SSD, other applications, OS/drivers or any number of factors. Ideally when going from Intel>AMD or vice versa you should do a fresh install.

i re installed windows completely on a new system

Scratch that OS reinstall part, anyway my go to solution is to check what's using the CPU in the background or if it's an interrupt issue. Try this & see if you have any process or services which could be causing this ~

I typically follow the Gamers Nexus rule... whatever the GPU calls for, add 100w, 200w for high end cards.
Get too cheap and you will get cheap
I always make sure it has OCP, OVP/UVP, OTP, SCP, etc. to protect your investment
Had to go up a few tiers on one of my builds just due to the 21 drives I had in it

 

[GenericNinja]

Did any storage devices or USB devices get transferred from the old system? In the last year alone I have had a client systems with a WD SATA HDD connected as a storage drive causing massive system performance loss and stuttering even when not being accessed, a SATA SAMSUNG SSD which would work normally and pass smart but randomly slow down to 100KB/s read and write while passing smart, a malfunctioning USB keyboard that was causing any mouse connected to the system to function only intermittently and an Intel 660P NVME SSD which caused memory management error BSODs. Bad PSUs cause instability, not stuttering.

 

[ChrisM255]

It was 1 nvme, 16 sata ssds and 4 HD. I still have the 16 ssds in hot swap bays but if my system was hitting a full load on everything and all the drives were accessed cuz they were all striped it would go into OCP and insta-off.
I've never had issues with my drives honestly in my personal stuff but for the last 10 plus years hard drives have just been backup storage or duplicate, something like that. Lots of dead drives at work with every issue you've ever heard of. I was so happy when the day came in the corporate life that we destroyed every hard drive in the building and went all SSD!
I'm still a storage geek... 3 x m.2, 21 sata SSDs using a cheap expansion card. Don't recommend Marvel controller, lots of issues... personally.


This was much better for me and uses more than just one lane like the 1X cards. Won't get server class speeds but you're not paying the server class price. A lot of the drives aren't hooked up right now that's why they're showing yellow.

Show me a game that stutters and I'll show you 10 poorly optimized games.

PSU causing game stutters, thats a good one.

 

[ChrisM255]

1) SEASONIC FOCUS GX-850W = 189USD

For your build I would go seasonic all day long
Funny thing is the PSU I was talking about having issues and going into ocp on me was a Masterwatt from Cooler Master

 

[Garra]

Considering all the messages saying that a faulty PSU will probably cause instability or other things , not stuttering and im a agree with that . I will keep reviewing my software options or other things . This is a new system , so i did a fresh install , the only things that remain from my old CPU is the PSU , one HDD disk and SSD disk , both of them i use them just to store documents. Also the GPU is also new i bought it like 4 months ago and used it with my previous 8700k.

Either way today i have to take my pc to the pc shop where i bought my new things because it seems the cooler came faulty, meaning that no pc to test new things for a few days .

I keep you guys posted , Thank you very much for all the messages!

yea on newegg a RM750e is 100, RM750x is 120 so little cheaper then rest. RM850x which i have is 135.
