hi so this is the situation i am in, currently deciding which hardware i am going to buy to build my first pc, stuck on deciding on the psu, my main options are the corsair rm850w or the rm1000w, the 850w is about £130 and the 1000 is about £150 but goes up to £170 when the places that stock it at £150 run out :
expected specs:
9800x3d
9070 xt
32gb ram
msi MAG X870 TOMAHAWK or MSI MPG B850 EDGE TI
so the 850w has 3 pcie connectors and the 1000w has 4 connectors, the motherboard has an extra connector for pcie so not sure if to connect that and if i have the 850w one i will only have 2 connectors left for the gpu and some of them need 3 pcie's and i dont want to limit myself to only ones that need 2 connectors, also some of the 9070 xt card say different minimum requirements for example the powercolor red devil i think says 900w so not sure if the 850w psu is suitable, so i would prefer to get the 850w to save some money and its easier to get hold of as the 1000w gets going out of stock at the lowest price but not sure about the minimum requirements and the need for more pcie connectors. hope someone can help me sort this out.thanks.
