Is it possible or safe to use 2 power supplies for 1 computer?

post #1 of 21
Thread Starter 
This is my last question i promise lol.

I have a friend offering to give me his old antec 520W power supply and i was thinking about using it just to power my HDD, fans DVD drive and my GTX 285 but im not entirely sure how to go about doing this or if its is even possible. I was also thinking about how safe it would be is there a high risk of being electrocuted or is it perfectly safe?

You need to get the signal lines from the 24-pin motherboard connector connected to the motherboard. That's it.

http://www.amazon.com/Vantacor-Dual-Adapter-Cable-2-way/dp/B00DL3L2J6/

That adapter was the first search result. No idea if it's good or not. It's pricey and I'd probably try to hack something together myself. tongue.gif

It will work, but is usually pointless. Your entire system could likely run on that 520W assuming an overclocked i7, unless there is significant hardware you aren't mentioning.

It is possible but I wouldn't do it. It is a pain, takes up a lot of space and you are better off with one good psu of appropriate wattage. My old system used two psu's and I regretted it.

Are you sure 520 is enough? EVGA says minimum is 550 with 40A 12V rail. As for hardware change yes i will be running 4 hard drives total 3 SATA II and 1 IDE plus i will be overclocking my processor to 3.12GHz unlocked to quad same as i had before my 600W died.

You're using a 400W system. 520W is plenty. I worked at EVGA as well; their recommendations are taken from Nvidia, who overestimates to cover their butts in case someone runs a high-end system off an overrated, crap PSU.

You're fine.

no need to buy such an expensive cable, enjoy, plug in, and your power supply will turn on, and you can use it accordingly and only 3.75
