    Great PSU so far. Upgraded from a 850W non-modular and this Corsair product has been great to use. However, keep in mind that you will need Corsair’s 12VHPWR cord to be able to use a 4090 with it.

    This bad boy is all you need, it lets you plug in only the cables you need to save space. It is longer than a standard psu, make sure there is space in the case.

    Good quality power supply needed a replacement because I tried being cheap when building my pc and it would not power on. Would buy some aftermarket modular cables if you want it to look nicer though.
