I couldn't find a review on the Fractal PSU from JohnnyGuru, I do believe TPU had done a review on it which was very good, so I would say that the going by the TPU review, the Fractal PSU would be the one I'd consider most. I can only go by what I use and the EVGA G+ has been great for me, but if it's a little too close to the maximum power for you, then I'd say the Fractal unit is the next best thing there :)

I couldn't see many good reviews about the Seasonic unit but I think there's a few lower quality/priced units out there, which I'm not sure is what you'd be after. I'm unsure on the Cooler Master unit as well.. I'd stay clear of that one

The Seasonic unit seems to be decent from reading reviews online, and JonnyGuru gave it a 9.6/10. That EVGA G1+ specifically (the G2 and G3 line is good) is actually not that good. It seems to be overpriced and has terrible transient response according to the reviews I found online. The cooler master unit is the same price as the seasonic unit, so I wouldn't bother. The last unit is also $20 more so it's not worth considering over the Seasonic unit.

It seems clear to me that the Seasonic PSU is the most sound choice of the four.

Maybe it's just me being picky, but the Seasonic unit in the review was an FX..? I was going with the assumption that the OP didn't mention the FX.. lol But as mentioned before, most Seasonic units are very good units :)
The reason I have the G+ units from EVGA was the price, when I bought them, they where something like £50 and £60 I think, half price basically! I don't think I could have done better at that price point... :D

Sounds like @PeterX9 has the nod from everyone for the Seasonic unit :D

Thank you all for your kind help.
I am now deciding between the Seasonic Focus plus gold 750W (SSR-750FX) and between the bequiet(ION+ 760p) since the TPU review mentions it one of the most silent psu (about 16 dbi avg noise), the place that has them on stock has only 15 USD difference between them (the Seasonic is the cheaper). I found a tomshw review about the seasonic that mentions it is noise under loads, so I am not sure yet.

Unless you live in a place where there's no noise, I don't think you'd ever notice any differences :) I can't say I have really hear any of my PSU fans (my 1200w EVGA P2 is a little noisy at times) but I only notice it when there's nothing going on around me. If the house is dead quiet, I just think, ah, louder music required :D

@Mr.Scott Do you use the Seasonic units for your benching? :)

Benchmark Scores Faster than yours... I'd bet on it. :)

At this point, you are really in the minutia. You can't go wrong with either. :)

How do you even hear that 1.2KW Platinum level PSU is beyond me...though your system specs say T (Titanium) and this say P (platinum).

Either way, I believe those have an eco mode where it doesn't spin up for a while.. I'd suggest using that. There is no reason a 1.2KW PSU with your system in the sig is running the fan. honestly. Hell, my 750W Evga G2 doesn't spin up in eco mode with a 4.5 GHz 7960x and 2080 Super....

I use Seasonic for everything. ;)
Only rig that doesn't have Seasonic in it is my SR-2 daily. That has an EVGA 750 in it, only because I got a screaming deal I couldn't pass on.

What's the smallest to biggest unit you use for Seasonic @Mr.Scott ? I'm just curious as you push the bounderies of all things when it comes to these components and I bet more than most on this forum, that you'd be able to share a few power draws from lower powered PSUs that surprised you etc.?

I mean as an example my SR-2 has a 1200w unit in it lol I found I was hitting nearly 600w for just a CPU overclock when I was benching back a few years ago... It's me on HWbot LOL

Nice link. I remember you Phill. :)
I have Seasonics from 430 to 1200 watts. It is my preferred brand after more than a decade of nothing but good luck. Only ever had a problem once, and their CS was outstanding.
Primarily for benching I'm on 750 or 1200.
Believe it or not, that is an 8 year old TurboCool 1200. Still cranks out stable voltage like no tomorrow.
My SR-2 / x2 5675 @ 4.3 (yes, that's my daily, lol) loaded hard will push not quite 700 watts on the EVGA 750, but it's only because I have a workstation vid card in it, otherwise it would be a lot higher. 750 watts would not be enough PSU to make me comfortable with a good gaming card in it.

My daily.

Thank you @Mr.Scott for your reply :D I think you might have your answer now @PeterX9 :D

For some reason this 1200w unit is a little noiser than most of my other EVGA units.. I think the bearing in the fan might be showing some signs of where and tear as I do get the odd squeek from it. I tend to not run it in Eco mode as for me I feel it gets too warm and when driving the 3900X + 2 1080TI's for folding, I'd rather have the fan going constantly. My rigs when on, do never idle at all. They are always under 100% load with the WCG :)
The 1200w I have is a P2 (I'll amend that, thank you!! :D) but I do have a 1600w T2 that's yet to be used.... I'll see if I can get a recording for you to show. Everything is on the desk, not in a case as yet and I think this is half the battle with this... Until I get the water loop sorted, it'll have to stay there because I don't have the bracket for the 14D air cooler to fit it properly too the motherboard.

But I digress.. @PeterX9 please post up some pictures and let us know what you think whenever you get the new PSU :) Would love to hear about it and your experience too :)

I bought the fractal ion+ 760p, since the local retailer only had a 5-year warranty for the Seasonic while the fractal had 10 years (as stated by the company).
I am now putting the build together however, this new PSU have 1x8 and 2x4 pin CPU power pin, and I'm not sure which of the 2 4pin should I plug onto the motherboard since both of them are compatible.

edit: compared both manual and it is the same, the lower 2 is the ground and the upper 2 is the 12V

I will post pictures tomorrow of the final build

From memory, any CPU 4/8 pin plugs I believe they only go in one way, so you might find that one is not the same as the other. I noticed it a while back with my EVGA PSUs, but you can always check by looking at the connections on the board and pairing them with the side that fits. I don't think that both sides of the 4 pin plugs would... Don't quote me tho as it might be different with the PSU you have :)

This is my before cable management picture, i am however struggling to get tests running since hwmonitor doesnt show motherboard or cpu temperate and freqency(neither msi afterburner). The uefi shows the temps but maybe the apps arent updated with 10th gen cpus?
