Enough power to overclock?
Enough power to overclock?
I'm looking to overclock my r9 290x lightning although I'm new to this so I'm just taking extra precaution. I'm not sure if I have enough power to overlock?
My power supply is a CX750M.
If possible I'd also appreciate exact numbers for overclocking the Power Limit, Core Clock and Memory Clock corresponding to my specs that are safe and not risky at all.
Thanks

You possess sufficient power, but CX series units tend to underperform, and you might face problems from output voltage fluctuations. I recommend giving it a try, though you shouldn't anticipate optimal outcomes—particularly since your MSI Lightning card is designed for overclocking. If you're willing to upgrade, the Rosewill Capstone G750 and EVGA 750B2 offer the most affordable high-quality power supplies at 750W (with the Capstone providing the superior option).

Mr Kagouris:
You possess sufficient power, but CX series aren't particularly strong, and you might face problems from voltage fluctuations. I recommend giving it a try, though don't anticipate top performance (especially with your MSI Lightning card, which is designed for overclocking). If you're willing to swap it out, the Rosewill Capstone G750 and the EVGA 750B2 are the most affordable options at 750W (the Capstone is the superior choice).
I've heard the EVGA SuperNOVA 750B2 is outstanding—something you referenced earlier, though in my area only the EVGA B2 850W is accessible. Would that suffice?
Well since you're not on a very strict budget I'd say a practical choice would be an EVGA 850 G2. Would allow Crossfire and it's a great PSU.
As for overclocking the card, as long as you're not touching the voltage there's actually no risk at all, although if you want to get any serious overclock out of such a good card you'd have to raise the voltage. Also, there's really no "exact numbers" as each card can reach different clocks, and even stability at a certain clockspeed can vary between cards (e.g. yours may be stable at 1100MHz but not 1105MHz, someone else's might be stable at 1105 but not 1100). I recommend you follow a GPU overclocking guide to get the most out of your card.
