Hi there,

my meg x399 creation has 2 CPU connectors (2X -8pins on mobo) , for overclocking enhacements.

Which power supply should I buy?

Nfortec Sagitta RGB 1050W 80 Plus Gold Full Modular - has it 2 CPU connectors? I see on the foto 2x CPU connectors 8pins..right? But the vendor said to buy an EVGA:

EVGA Supernova 750 GT 750W 80 Plus Gold Modular - is 750W enough for 2x gtx 1070Ti and threadripp 2920X ??


What is the best option, I want those 2x 8pin CPU 12v. connectors ..connected on this mobo!!

Depends on the rest of your system. If you going to put a bunch of drives and a high end gpu go with the higher watts. That said I don't know anything about Nfortec Sagitta. So I can't comment on the quality of that psu. Between a TR3 and a high end gpu like a 3080/3090 you looking at 600-700w alone for those 2 parts.

I'd get the eVGA, it seems like they're made by Seasonic........the other brand sounds like something you'd get from aliexpress.

Unfortunately, you're in a bad time to buy a high-wattage PSU, the prices are ridiculous. I'm gonna build a new system soon, but I won't be needing more than 750W and I'll be getting an eVGA (The Seasonic and Corsair same wattage and kind and price) over those other brands because ALL of their cables are sleeved, whereas the other ones don't sleeve.
I think you would need no less than 1,000W. For one card a 650W PSU is recommended.

I believe I read on LTT forum somewhere that Sagitta has a fake 80 plus gold rating in one of jonnyguru's post, I would look for a decent 850w PSU if I were you if the 1000w from a decent brand are hard to find.

750W should have no problems with x2 1070 ti. The one I have only requires 1x 6pin power so that makes it even less of a hassle with cable management.
