I was working SR; all sectors combined. Using multi-mode; I had a South Handoff Controller working for me due to the ZZZ RADAR failing earlier in the day when the entire RADAR room went dark; including the RADAR scope; radios; and all lighting. I attempted to transmit but did not appear to be going out. I made a blind transmission that ZZZ had suffered a major equipment failure to maintain VFR and attempt to contact ZZZ ATCT. The RADAR room was OTS for several minutes; not sure how long before power returned. We eventually resumed RADAR service in ES (emergency service mode) then Full service when power became available. Ensure back-up power supply is maintained and/or monitored and possibly included in Watch check-list to prevent total loss of services.
TRACON Controller described the total failure of RADAR; Radio and all facility electrical inputs; the reporter improved attention to local 'contingency' plans.
