hi there, I have been searching on this forums for some time now and finally decided to register. I've decided to upgrade my 7870 to a gtx970 and will oveclock my atm stock AMD fx6300 (although I will upgrade to an i5 in the future), was wondering ig a Corsair CX500 will be enough for this and also want to know if my cooler (tx3 evo) will be enough for a mild OC...
my complete specs:
AMD FX 6300
Cooler Master TX3 Evo
g.skil rpijawz ddr3 1600 2x4gb
Sapphire Radeon 7870 ghz edition
1tb WD Caviar Blue
Corsair CX500 psu

thanks, and nice to be on the forums :bounce:

It should likely be fine for the GTX 970 for the time being as HD 7870 consumes more power than the 970.

BUT, OCing FX on this CPU is not recommended, CX uses low quality caps which are not rated to deliver high loads continously, so your OC may not be stable and the PSU may even fail, taking some components along with it.

So all in all, I think it's a bad idea to OC FX 6 on CX, but upgrading to 970 alone will likely not be an issue.

Corsair is a big name with lots of products under its hood, including some of the best PSUs ever produced. Its just that people often use their budget units for things they're not meant to do.

ok, so from what I gather here, it's enough to power the gtx970, but may not be sufficient for a decent oc due to quality, ah, forgot to mention my mobo is a Gigabyte GA 970 UD3

thanks guys ^^ think I'm gonna go for it then, maybe the fx 6300 will bottleneck the 970 but I think I will notice the difference anyway, and it's only till I gather enough money to get an i5 4690 or something like that :D

Can you expand that thought coz im getting confused... are you suggesting this can live with 375 of power draw but not 400? Did you even calculate possible power draw with OC or just shoot your answer from the air?

The so called quality is maybe important to drain that few more Mhz from the CPU but it doesn't mean you wont be able to overclock at all.... I'm just surprised how many of such recommendations would led to spending unnecessary cash.

He owns the PSU from what i see, if it fails it fails, if it wont allow overclocking it wont... but saying it wont before even testing is simply stupid.
 




I am not liable to justifty my answer to anyone who doesn't care about the words he's using.
 


Thou shall not use 'bad, abusive' words here in the forums.

sooo... you're suggestiong that it's is better to not spend unnecessary cash and test for myself and see if something goes kaputt rather than take advice from someone who seems to know what he's talking about...
 


It shows that he's an amateur.

 
I've no issues with your arguement, and I'll be happy to justify my response, what I am not fit with is the abuse you hurled.

Anyways, my justification:

HD 7870 is a 175W card and 970 is 145W, so there are no issues with replacing the cards as that won't give any extra load to PSU.

Now to OCing. The fact that you're missing is that PSU quality (not wattage) solely determines the regulation of voltage given to CPU. OCing will require more Voltage draw and so PSU needs to give out more Voltage, and more importantly, give it out continously. That is why quality is important. Low quality caps used in CX have been observed to fail to provide continous and regulated voltage. And lack of correct and continous power will result in instability. It's as simple as that.

Finally we are getting something:
1) more Voltage - false statement not all overclocking requires increasing voltage of CPU
2) voltage is taken from mobo which hase own regulators, all u need to get is few more amps or miliamps from 12V power rail thats why its more important to have quality mobo
3) its possible to overclock nicelly with good mobo and shitty PSU but not other way around
4) obviously its good to have everything top quality but in some cases you are getting crazy further than you should.

...and yes I'm an amateur grown on 386 PC's... Alan do you even know what is it?
 


Grown on very old PCs. I too was grown up with a Pentium III 533 MHz. I study 9th grade.

 
1. Not talking in the sense of the Voltage we set in the MoBo for CPU. The PSU converts the Voltage from mains to different Voltages, like 3.3V, 5V, 12V, etc. Read about PSU's voltage regulation. Good FAQ here:
http://www.jonnyguru.com/modules.php?name=NDFAQs

2. The voltage taken by the CPU from the MoBo is provided by the PSU. Try OCing i7 with Maximus Formula and CX500 :lol:

3. Hit and miss. You can theorotically power up a R9 290 on CX 500 with FX 8, if that's the case.

4. No.

PS: 10th Grader here, assembled one rig (yay?).

I too started with an 386 playing Prince of Persia, Secret Agent, Jill of the Jungle etc... that doesn't mean I am an expert in overclocking, anyway, I have the answer I need, thanks. I think further discussion will only lead to insults, and Ra_v_en, insulting other people or judging them without knowing is not the best way of discussing, even less when it's clear that they are trying to help.

Sorry Aryend i didn't want to drag it that far on this topic but spreading this "quality" nonsense has to end.

Now back to the talk with the specialist... you just done the math and calculated that only swapping 7870 to 970 gives 30W savings from 12V rail which can be spend on overclocking that FX within the same total power drain from the PSU.... ill pass the talk those 175W and 145W numbers since its also "on papers"... put those cards into bitcoin mining and you will see what I'm talking about... but lets assume you are right.

Now if you look closer at any decent OC tests you can estimate what will be the power drain after the OC:
http://www.play3r.net/reviews/amd-piledriver-fx-4350-fx6350-fx-8350-shootout-review/10/

" When I hit 4.6 with the FX-6300, it jumped around 60 watts at the wall."

CPU(95)+GPU(145+)+THE_REST(50W) / 0,8 (bronze cert efficiency) +60W(raw difference from OC'ing) = 422W
... thats 85% of declared 500W
Now nobody say he need to be so eager to get at point of 4.6 Ghz.. he might be more sensible, like i would and get some good spot without drastic overvoltage nor temperatures getting sky high since that is indeed stupid.
He could even only use that 30W for OC only saved from swapping the cards... thats still OC in my vocabulary but logically its the same level of possible PSU failure... if you claim different then please enlighten me.

I'm not gonna say how many PC's did i build since its irrelevant to the topic and i did build fair enough to have some knowledge.
On the other hand i did build my own setups which is only top of the ice like P200 @ 250Mhz, Celeron 300A @ 483Mhz (volt mod), P3 500@800Mhz, Athlon XP 2k+@2,2Ghz (volt+multiplier mod), Athlon mXP 3k+ @ 3Ghz (volt+multiplier mod), Athlon 64 3k+ @ 2,5Ghz, C2D 8400@3,8 Ghz, C2Q 8400 @3,5Ghz... and Xeon 1230v2 @ stock lol

MeteorsRaining im very glad of your input in the forum with MB Tier List.. etc... but please give me numbers to prove I'm wrong, which i would gladly take on my chest in favor of learning something new or you are simply talking bullshit.


Edit: Did also the math about your suggested 290+ FX8... 125+275+50 /0.8 = 565... nope not even theoretically ;)

AMD 7870 uses less energy then gtx 970...
On a tomshardware article about them they stated that this cards can pull even up to 300 w occasionally in a short moments... Maxwell is great but no gtx 970 uses less energy then 7870 or my R9 270x. And i am planning to buy one so just to be fair. If you want to i can paste link from tomshardware article but i think you can find it yourself.

thanks, from what I'm seeing here seems like the difference is not that much though, I see that the max consumption of the 7870 is at 166w and the max of the 970 is at 173w, so the difference seems neglible, although the average seems quite a bit higher.
