ok. so i have chosen CORSAIR CMPSU-620HX 620W ATX12V v2.2 and EPS12V 2.91 since its ATX it will fit in the 690CM right ? but since the case design puts the psu on the bottom, will that cause any problems with the fitting of any kind ?
no, it will fit perfectly. the only problem you might have is short cables. well, the cables will be long enough to conect with the motherboard, but if you plan on doing some cable management, then i might be alittle short.
