4pin EPS enough for amd fx 8350?

[Xevan]

Hello everyone, i hope im writing into correct forum section.
Today i got MSI 970 gaming Mobo and i did not realized its cpu power supply has 8pins. I have chieftec GPA-500S8 PSU and it has only 4pins for the cpu.
I was searching on internet for hours but didnt found anything. Can i use amd fx 8350 cpu with this PSU? My gpu is Asus Geforce GTX 1050 4gb cerberus. Or would it be too risky? Im not in any position to buy new PSU anytime soon.
Ill be thankful for help

Yes, you can, as long as you're not overclocking the cpu too much.

Thank you soo much for such a quick reply, i dont plan to overclock, especially since im just casual gamer. Ill save up slowly for better PSU just in case. Thank you again, i was really down about this.

No, and unless you wanna have a dead CPU+PSU+mobo, don't do that.
Super bad hardware combo.
Maybe if you had an FX-4100/FX-4300.
Not the big one. FX-8***

Board with cheap mosfets cannot take+PSU cannot take.

I say bad idea.

Save up and upgrade to ryzen, that's what I did

970 mobo..wow

That's getting back there.

 

[Xevan]

Well i dont have money for new one mobo right now, this was given to me so i took it

FX 4100-4300 should be OK with that PSU and your GPU.
Probably a "locked" B59 or B60, too.
By "locked" I mean I think the multiplier is unlocked, but the extra 2 cores aren't.
Those chips unlock to fully functional quads more often than not.

Well i have 8350 amx cpu
Im already using it on mobo that supports cpus only up to 95W
So idk whats worse, cpu works but throts every 10 seconds.. but ill try to find some cheap replacement for PSU, before ill be able to save up for proper one

A b59 or B60 might be a lot cheaper than a PSU and you could use your computer.

Ive witnessed 970 boards run 8350s stock or OC'd

@ShrimpBrime @storm-chaser @Bones @Mr.Scott can attest to this.

Read the manual

 

[XL-R8R]

Anything over 150w on a single 4-pin EPS connector is not a wise decision; the max supported (unofficially) is 168w (150w official) and combined with the other 4-pin, maxes out @ 336w, or there abouts.



TDP for the FX83 spoke about is 125w... it should work fine so long as no overclocking takes place.


You could also slightly reduce the stock voltage and still maintain the same default clock speeds of the CPU - this will assist with keeping the wattage used to a minimum for safe operation.






Edit -> Suggesting the person change CPU or PSU when clearly on a tight budget, is fairly dumb. @everyone doing this.

Good idea! Undervolt and underclock some and should be safe! (Also free) Or maybe even undervolt and overclock!

 

[EarthDog]

Yikes.....

1. That PSU is more than likely trash... Oof. Chieftec...
2. As XL-R8R said, the TDP is 125W, so long as you are at stock a single 4-pin EPS is fine. Worst case, you can underclock (though you will lose performance gaming as that CPU is already holding things back at 1080p because its so slow).

but ill try to find some cheap replacement for PSU

That's how you bought a POS PSU in the first place. You do not want to get another low quality unit like that again. Even going in blind choosing ANY PSU from Corsair and Seasonic yields decent to GREAT PSUs.

Edit:

So idk whats worse, cpu works but throts every 10 seconds..

Get some air moving across those VRMs..... that will help. Again cheap arse board with weak arse power delivery being fed by a garbage PSU... bleh.

 

[dirtyferret]

perhaps you are willing to buy him a new ryzen, mobo and most likely RAM?

 

[Bones]

I'll throw in - It can be OC'ed with an 8350 but not by alot. I would only run it with a small OC at the most and even then I'd keep an eye on VRM temps. This board TBH is best left at stock with an FX chip to avoid potential for trouble.

If it's going to be OC'ed more than just lightly you'd need a chip rated for less than 125W's for sure, could be a 95W rated chip would be a little too much there too. As odd as it may sound there are some 4 core FX chips rated for 125W and some 8 cores chips rated for 95W's - Go figure.

BTW these values will change QUICKLY when the OC'ing starts.

I'd use it with an Athlon II or Sempron all day for any kind of useage but for FX, I don't think the board would live too long if leaning on it. Key thing here is the wattage the chip would be.
And DO NOT EVEN THINK about dropping an FX 9xxx chip in - Instant death!

Im not planning to play games at ultra high and such, atleast till i completelly upgrade everything. Rn i just want to play some older games.
And that PSU came with the pc, sadly. Pc was bought long time ago.
I got cpu and gpu, but old mobo is bad.
Got the msi 970 mobo for free so hoped it would help, didnt knew it has 8pins for the cpu power.

So from what i gathered from suggestions here. I can use this mobo with this bad SPU so long i wont be OC right? Then im gonna save up for 2 months and buy new PSU asap

Sounds about right...

If you are throttling already though, get some air moving across the VRMs... that should help.

 

[Bones]

If possible I'd get and run either an FX-8300 or 8320E, those are 95W rated chips vs 125W for an 8350 and if ran at stock would probrably be just fine for the long haul. Don't underestimate an 8300, it's actually a good chip to use.

Placing a small fan at the VRM's regardless would be a good move to help prevent throttling, if the VRM's get too hot that's what will happen.

The PSU you have now just won't cut it long term, as long as you leave it running at stock it will probrably "Get you there" until the new PSU is in but understand it's not going to live long if you decide to start cranking more speed from it. OC'ing with any chip raises wattage draw and you're already close to the line as is.

Also make sure the case it's going into has good airflow, in and out the case or you'll probrably start cooking things in short order, be sure to make all that good while you're at it if you want it to do well and live a long time.
I know you're probrably strapped for cash but definitely don't want to see you invest in it, just to have it all go up in smoke in the end.

 

[EarthDog]

He already has the CPU, gents......it is what it is...

 

[Xevan]

No i wont OC, atleast till i get the new PSU
Right now all i needed to know is if i can use it now at stock. So thanks alot everyone, for your time . Ill be looking for some PSU up till 60 eur. Should be able to buy in March or April

 

[EarthDog]

atleast till i get the new PSU

..and if you are throttling already............. overclocking isn't in the cards even with a better PSU.

You have multiple issues...

1. The processor out of the box is a slug and already holds games back at 1080p (though 60 fp is in the cards, there is a glass ceiling with that CPU)
2. The board's VRMs are MEH
3. Your PSU is junk.

A better PSU will carry over to a new system at least. BUt I'd start looking to save up for a new system. $400 gets you a Second Gen Ryzen CPU 6c/12t CPU, a decent motherboard and RAM.

If you have the MSI 970A-G46 Like I do then yeah it's fine and YES you can OC the HELL out of the CPU then, Just one thing I would do is leave the I/O shield off let the CPU fan blow the air over the VRM heat-sink.

 

[thebluebumblebee]

And that PSU came with the pc, sadly. Pc was bought long time ago.

Let me guess, a case with a single fan, maybe even as small as 80 mm?

If you are throttling already though, get some air moving across the VRMs... that should help.

Just get air moving period. What CPU cooler do you have?

But he doesn't. Read the first post.
