it is a saphire nitro plus vapor x i checked the contents of xpg core reactor 2 and it comes with a 12vhpwr now i do know that it is used with 4090 but i dont know if it will work with 7900xtx so is the 12vhpwr fine or should i go with corsair rm850x which comes with 2 8pin cables so i guess i have to buy one speratly?

still confused

I would use nothing less than a 1000 watt power supply for ample headroom and peripherals that all consume power. Transient power spikes require the extra juice from a quality high wattage power supply to maintain stability. Gamers Nexus  GPU transient power spike testing.

Is it from a AIB or AMD? Because some AIB's will push the design even more.

Anyway, get a 850Watt Platinum PSU and you are ready to go.

=OR=

Future proof with 1000Watt.


BEWARE THAT!

Not every PSU comes with 3 individual 8pin cables, normally its 2x2 in daisy chain on the affordable models, double check what the package brings along.

Look for one like this seasonic prime 850 gold that has 3 direct 8 pin cables.

The 12vphwr won't work with the 7900XTX. Stay safe, avoid fire hazards.

I understand Ur concern but a lot of my friends have a 850w PSU and they are fine they all either have a 4070ti or 7900xtx besides that 1000w PSU are a lot costly than 850w PSU where I live so that's why I'm going for this build
