The Leadex Platinum is better simply because it has LLC+DC-DC, rather than the ACRF primary on the EVGA (the ACRF design on the EVGA can lead to things like coil whine on high transient power GPUs like the 3080Ti, due to hard switching), but the Super Flower has no proper reviews so might be better to pick another one

However the Leadex Platinum SE is listed as a Tier A PSU, so it might be fine

Also I think the G+ is EOL'ed, if the tier list is correct

...also do you really need 1kW PSUs?  You can power something like an entry level HEDT build with it

For RM1K - there are better choices out there, like this:

IMHO a 850W unit should be fine for your machine, and the 3080Ti isn't worth it pricing-wise (the vanilla 3080 is better)

Quite a few, probably these should do the trick:

(XPG Core Reactor, probably the best unit out there)

Dear All Sifus,

I have a PC around 10 years+ and those are my CPU spec :

1.Processor Intel Xeon E3-1230
2.Graphic Card AMD Radeon HD 7870
3.Motherboard Intel Desktop Board DH77KC
4.RAM               DDR3
5.Data storage SSD SATA x 2, HDD SATA x 3
6.Cooling Fans 120mm x 5 (no LED)
7. PSU               Seasonic S12II Bronze 620W
Problem : Hardly to turn on the CPU. If i success turn on and it will turn off again once enter to window
I suspect it's PSU problem. Is that the PSU aging or problem ?
Any PSU recommend for me (if it is the PSU Problem)

Thank you very much

Yes, i had try few times, when i am in BIOS mode, the CPU shut down too.
any PSU recommend to replace the old one ?thanks you very much

How to know that the CPU is overheat? *the processor fan is working fine
thanks for the recommendation, i choose 500w,550w or 600w ?

thank you very much
i fail to check the cpu temperature because it shut down when i go in bios mode.
so now mean either is PSU problem or CPU temperature over high, right ?

so i need to change which part of the hardware first ? PSU or CPU cooler ?

So, do you know i'm from which company??

Cannot, you 3 stars only

Just come back when you got 5 *
