Epilogue
The ASRock SL-1200G wasn’t available at the time of the review in any of the US stores I searched, so I had to contact ASRock’s PR to get price info, which is set at $188.5. This is a fair price given this unit’s features. Besides Platinum efficiency and low noise output, you also get ATX v3.1 compliance and two 12+4 pin connectors for an equal number of 12V-2×6 cables. If you try to power a couple of RTX 5090s with this unit, things might not go well, especially if you use a power-hungry CPU, so I suggest you remain at RTX 5080 cards if you plan on utilizing both 12V-2×6 cables.
With more competitive ripple suppression, better transient response on the minor rails, higher PF readings (especially at 230V), and a longer hold-up time, this unit would have a highly competitive overall performance score. Still, it would also cost more since larger bulk caps are required for a longer hold-up time, and on top of that, the PCB had to be larger to accommodate these caps. I don’t agree with the newer ATX v3.1 spec that loosens up the hold-up requirement, dropping it from 17ms to 12ms, and this is why I will mention it in my reviews and include it in the cons list.
All in all, the ASRock SL-1200G is worth considering, especially if it is offered at the price that I was provided with, $188.5, given that most 1200W Platinum PSUs exceed $200. The only exception to this pricing scheme is the Montech Century II – 1200W, which is currently sold at the crazy price of $125, putting fire to the competition. As it seems, Montech was to enter the PSU market so badly that it decided to minimize its profits. Hope this works well for them!
Before investing in a new power supply, read my Best ATX v3.x PSUs article to check all alternative PSU offerings. You help me a lot by using my affiliate links, which don’t increase the price of the product. I receive a commission from Amazon every time you do it, which can make a significant difference for me, especially now that I am working independently, exclusively for my media, rather than for someone else.

Aris would u update Gamemax Lioncore 1000/1200P series, i’ve seen they just had cybenetics platinum ratings
I will review them at some point. Their OEM is doing some serious effort to improve, and I try to help them (as I do with all the other OEMs who send me products for testing)
Love your work but could you in future articles explain every test with simple explanation? I always forget what’s what and have to go to your Tom’s HW reviews to check 😀
For example from the Hold up time segment there: “Put simply; hold-up time is the amount of time that the system can continue to run without shutting down or rebooting during a power interruption.”
If you could mention briefly at the beginning of each test that would be great. If it’s not hassle to paste it every time of course 🙂
I’m still rocking a 2019 Seasonic Focus GX which I picked based on Jonny Guru’s review and I’m afraid that it will die soon so started my research and I’m glad to see that there is a new Guru in the PSU review space so thank you for your work.
Also, your reviews now made me hesitant to buy Seasonic when the time is here lol hopefully they are still reliable even though they are now midrange in these tests
Will see what I can do about that 🙂 Thank you!
I really was hoping für the FSP Mega TI to be next in line…
FSP is still working on this…
