Power Cord replacement advice

by papomusik / December 7, 2012 11:11 AM PST

Can I use a generic power cord replacement 10 A / 125 V for the following Mac Pro Tower 2010?

1. Model A1289 EMC No 2314 / 100-240VA / 0-Hz 12-5 A

2. Specs (as in manual) Power Supply AC line input:

Voltage ranges: 100-240 V alternating current (AC)
Current: Maximun of 12 A (low voltage range) or 6 A (high voltage range)
Frecuency: 50 - 60Hz

3. Also, I get a power cord recommendation from Monoprice:
"These cables support up to 125 votls 13 amps we dont offer ojne rated for higher. If you are only pushing 120 volts it should work":

I'll appreciate any help and advice you can give me.

A/C line cord

That shouldn't be a problem, of course it is a good idea with any system to use a real surge protector(not just a strip) or an APC to input to.

Should be fine.

Good to see someone analyze all the specs, but it's a power cord plain and simple.

Thanks to all of you for your answer and help. I learned that the power cord I need must be 12A (A=amperage) or more, so the generic power cord 10A I have is no good enough. I ordered
An excellence one from monoprice: Product 5290 (15A):

2ft 14AWG Power Cord Cable w/ 3 Conductor PC Power Connector Socket (C13/5-15P) - Black
"14AWG are our most robust cables; extra thick and heavy duty to handle connections to the beefiest power supplies. These cables are designed to carry up to a 15 amp, 125 volt load. They are safe, strong and reliable"]

pg3: You are right. I always use a USP System. I got a new brand CyberPower CP1500PFCLCD .
(PFC Sinewave UPS Systems - Pure Sine Wave | 100% Active PFC compatible)
My Mac Pro has an Active PFC Power Supply so it needs a USP System like that one.

It would still be fine.

Good advise

No, I didn't have measure those amperes, but I like very much your advice and I will. I just lost the original Mac's power cord and I didn't (I still don't) know if it was designed to carry up 10 or more amperes (as many other equipment I have)

I just didn't want to take any risk, (and logic and the common sense dictates), I must get another with the same "specs" as the original one, (but not so expensive). So, after looking for some advice here and other forums, I was told (according the "specs" I provided) the replacement one must be at least 12A, or more. It was good to find that Monoprice, in addition to other cables for A/V, they also sell this PC cable. I had more luck, 'cause I get the short length 2ft I needed, but stronger, it is 15A, not just 18-16WG, but also 14WG, for just $1.78.

Good thinking.

Some will write this is over analysis but you're just making sure there is no issue. That's fine.

Good price too.
