Area-51 R2 dp/n 800GY Delta Electronics 1500w / 1440w 12v Max Power Cord 

original power cord

depending on your country, USA uses a C19 5 15P >< Heads-up: found 1500W psu stock A-51 R2

• C19 server-grade for psu
• 5 15P for USA wall socket
• 14awg / 14gauge
• 15amp | 16amp
• high-temp jacket of 60c - 105c
• 6 - 10ft preferred

My cord is 10feet long, 60c temp insulating jacket 300v 14awg, plug says 15amp 125v. My beefier 6foot cord for Nzxt Hale90 1200w is rated 105c 300v 14gauge 16amp 125v. You're encouraged to google-fu the above specs. A C19 sqware 14awg 6-10ft with a wall-socket male-pronged-end appropriate for your country 'should' suffice

Low-power & non-server-grade PSU's will most likely use a C13 (5 15p) 18awg|16awg (fatter)
