Changing PSU - Could PSU affect my CPU Overclock?

Hi all

I am upgrading my GPU from a venerable 6850 to an R9 280x.

In the process I realised that my 650w Antec PSU could probably do with some upgrading at the same time. It has been toiling away for about 7 years. I've opted for an 850w XFX semi modular PSU to cover my needs.

When it comes to the silicon lottery my 4670k appears to have been at the bottom end of the scale. Nothing above 4.2 has been stable without unacceptable (to me) voltages.

I wondered if a new, hopefully more stable PSU, would allow me to push it that extra bit further?

I will for sure post some before and after info once the new kit is installed. I just wondered if I might be getting my hopes up for nothing. It would be really nice to get an extra bit of juice from the CPU.

Looking forward to getting some new parts to play with!

Edit: I do appreciate this doesn't fall into the high-end category but it is still exciting for me! 4.2 required about 1.32v for stable running but I do have good cooling via a Noctua NH-D14. If I could squeeze an extra coupla hundred from my shitty CPU I would be really chuffed.

a more efficient PSU that delivers "cleaner" power with less interference and fluctuation in the voltage will allow higher overclocking. Unfortunately, this is not always typical and there are other factors that limit overclockability such as the strength of your motherboard and the luck of the silicone lottery. If you have an entry-level motherboard that wasn't designed for overclocking, you won't see much improvement and of course, it's completely possible that 4.2 is the limit of your CPU and no amount of optimized hardware will help you push further.

Thanks Ellis - the thought that I might be able to push my CPU a bit further was not something I had considered until I got close to delivery date! I was so disappointed with the 4670. I spent a good two weeks battering it with overclocks and had to settle with 4.2 as my running speed. Compared to the 3.4 E7300 I had it was a pretty good improvement! I just thought I might get more out of it!

I suppose if I am honest I was hoping for 4.4 but having looked back, probably unachievable with that CPU on air.

Still - I have the fun of trying it all out again and seeing if the new PSU changes anything.

Been a long time since I bought a PSU as evidenced in my earlier post! Can't wait to get rid of some cables as well. My setup is pretty tidy, the R4 is a very neat case for cables. It mainly hides them all in the back panel! What I can't see doesn't bother me - it's front panel connectors are pretty loose though.

I'd be bet you'd definitely be seeing more stable performance regardless. I was actually able to squeeze almost 500mhz out of a Phenom II x6 just by upgrading from a corsair TX 80plus PSU to a corsair RM 80plus Gold PSU. With the old PSU, I was peaking at 3.7ghz but after, I was able to get it to 4.1ghz.

(I posted a thing but it seems to have disappeared!)

It doesn't seem to have made much of a difference so far. I'm currently stuck getting 4.3 stable. I'm at 1.31v so far on the CPU and it's not solid at all. Surprised it has let me post this!

Still - it's not the end of the world. The PSU is running sweetly atm and my first ever eBay purchase (the R9 280x) seems to be performing quietly and cool.

Upwards and onwards.

Edit: I've hit my patience limit after trying to get 4.3 stable. I did briefly try 4.4 just to see if it would behave differently but to no avail. I guess the answer to my original question is that, yes, I can hit my 4.2 slightly easier. Getting beyond that is just not possible with this chip and my limited knowledge. It has been fun trying however!
