silverstone strider 750w

[Dimitris K.]

I have this power supply http://www.overclock3d.net/reviews/power_supply/silverstone_strider_750w_st75f_psu/1 and i am wondering if it is good enough to power an evga gtx 780. I tried to search around but since it's quite an old psu i didn't find anything helpful but instead i got confused about its quad 12V rail and if it is not good or not. Don't know if it matters but the rest of my system is :
i7 2600k @ 4ghz-corsair h100i
Gigabyte z68x
8Gb ram
1 ssd - 2 hdd

More than enough to run it, A friend of mine runs 2 x 780's from an 850w PSU stable so 750w will be more than you need for a single 780

To put it in a different light, 2 x GTX 780 Ti's at load use just over 500w, That still leaves 250w for the Mobo, CPU and Memory, So you should be all good

What got me confused was the evga's 42 Amps requirement, and some crazy talk about quad 12v rails where i got lost.

Just make sure to plug the CPU/Mobo/GPU all on their own rails. Have to spread out the load multi rail PSUs.

Now what does this mean exactly? My psu has 2 pic-e 6 pin slots and it has 2 Y pic-e 6 pin cables giving a total of 4 6 pin cables. I was going to use the first Y cable with the 8 pin adaptor and the one 6 pin cable from the second Y cable to power the card. Is there another way to do it ? The card also includes a molex to 6 pin adaptor but wasn's planning on using it. (Yes, I am a noob )

42amps on 12V rail is 504W. thats a reccommandation for the entire system + headroom for a pc with a gtx 780 in it. your psu can power 2

Its a quad rail psu. Each rail can only hold a quarter of the total power. Have to spread it out.
