The M12II models perform well, though the 520w and 620w versions are internally regulated. (Higher capacity models such as 750w and 850w lack this regulation.) These units don’t work well with the C6/C7 sleep states of Haswell and newer Intel processors unless you disable those states in the BIOS. This undermines the efficiency gains, but since you’re overclocking it’s not a major concern. Group regulated models aren’t as effective as self-regulated DC-DC components, so a newer platform is strongly advised to prevent crossloading problems. For Seasonic, consider G series, Focus Plus, or Prime units. Avoid Cooler Master options as they’re rare on stable platforms and usually pricier than comparable brands like Seasonic, EVGA (B2, G2, G3, P2, T2 only; steer clear of N1, W1, B1, BQ, and Supernova NEX), Corsair (TX, HX, RM, AX – good except CX and CXm), or Super Flower (Golden green and Leadex platforms). Antec True Power Classic and High current gamer units are solid choices. However, the High current gamer models are also regulated. The True Power Classic units, especially newer ones, aren’t. If the M12II is your only option locally, it’s still possible to do better – the 520w model should suffice for some overclocking, while the 620w offers more flexibility if you plan to push overclocks or upgrade later. Make sure to disable C6/C7 sleep states in the BIOS if using an M12II or S12II. No issues expected with G, Focus, or Prime series. For more details, see: And:
If you install the Seasonic M12ii 520w and boost your CPU and GPU, could you encounter crossloading problems? The issue is that you've heavily invested in the GPU and CPU, leaving little room for further upgrades.
Truly, for most people, turning off those power settings will likely make it hard to tell the difference. There are far worse decisions to be made. If you manage to obtain a 2017 model of the Corsair CXm 550w, it would still be a reasonable budget option. It should definitely be from 2017. The 2015 and earlier models had inferior cooling caps on the secondary side, and the heat management wasn't sufficient to prevent the cheaper caps from overheating and failing prematurely.
If you're looking for something better, consider Corsair TX units—they perform a bit better.
What country are you from?
I'm located in India, and the local options include Corsair, Cooler Master, and Seasonic. Antec is accessible online, likely on Amazon. Honestly, sleep modes aren't a concern for me. I could turn off power states since I usually run my PC for gaming. The main concerns are whether my PSU can supply enough power for overclocking (including adding voltage if the memory clock needs to reach 9GBps) and handling crossloading issues. That's why I was thinking about the Seasonic M12ii 520W.

If you’re lucky enough to find a Corsair TX unit, those are slightly better as well.
