Yes Antec have great power supplies. However the one you listed is untiered and I wouldn't recommend it. Do you have a budget and please post the rest of the specs.
VP550P is a budget PSU from Antec, and its better than many other PSUs (corsair VS/ CX/ CS/ CXM/ builder), on level with EVGA 500B/600B.
