aliessayli2 wrotecan one replace
Cooler Master RS750-AMAAG1 V750 80 Plus Gold Semi-Modular (90% efficiency)
with
Cooler Master RS700-ACABB1 B700W Ver.2 700W PSU (85% efficiency)
for the same build above ?
its a 65$ difference I would like to cut from my budget.
Don't do it, the B700 is made for the most basic builds, it's in no way a good idea to put it in a high-end system, paying $66 is nothing compared to potentially paying $1300 because your PSU destroyed your PC, as PSUs tend to take something with then when they eventually die, unless they're high-end units that simply died from brownouts or from long use.
Never cheap out on the power supply! You don't want to learn this the hard way.
