Is This Too Much Strain On Single Chord?

I'm running a Great Wall e750 750w 80Plus Gold ATX 12v power supply in my current system. I only have one SATA power cable available, which comes equipped with three SATA connectors.

The first, I have running to my fan control board on the back of my motherboard. The other two have splitters on them for my hard drives. So on the second SATA connector, I have a two drives from it via splitter #1. On the third SATA connector, I have two more drives via splitter #2. So that's a total of 5x things sources pulling power from the one sata power cable. I wanted to verify I'm not overwhelming that one chord with my devices.

But here's the catch...

I stored all the cables long ago and they were lost in a move. And I'm too paranoid to buy an aftermarket cable that doesn't match, as I've heard horror stories about that. I've not had any issues thus far, but don't want to be unneeded strain on any of my equipment.

Thoughts?

 

Almost all power supplies I have worked on, all the power cables are all soldered together inside. I kind of doubt if those components are too much for the wires. After it has been running for a few hours, feel the wires, if warm then you may have an issue. I am guessing that you have a modular power supply? And lost the cables that plug into it?

Note posting the same questions in multiple sites or multiple forums is considered poor forum etiquette. Make sure you go back to every place you posted to avoid leaving any open threads dangling - also considered poor forum etiquette.

 

Thanks for responding.

As for the etiquette point, I always make sure everyone has the info once I've found it. Waiting around for a week with no replies on a single thread (which has happened on this forum in fact) puts me too far behind. I have better results (and faster) exploring multiple forums simultaneously. It just works better. And I'm always happy to thank anyone who offers info. So I don't fear the perception of poor etiquette. I've seen a lot worse.

 

Solution:

I received some advice on another forum to just find the individual watts per device (which I didn't realize you could find online, I thought I'd have to pull every piece of equipment individually to find that).

So it looks like my fans are only running a 1.08 watts each, and the average watts per drive is around 6-7 watts. But that's only when active, when idle they are much less. So I'd assume I'd have to be pushing all four drives simultaneously to max out that power, which I can't see doing.

So my new calculation on that one chord is around 32-35 watts on the 52 watt cable. So I feel much more comfortable now. Thanks!
