I'm looking into getting a Asus 660 Ti DirectCU II and am wondering if my power supply will be able to handle it. Ive read on a few forum posts that you should have a 6-pin 25A rail but I have 2 6-pin 19A rails. When I checked out the specs for the GPU on nvidias website it just says it requires 2 6-pin connectors.
Here's an image of all the rails the PSU has. Also, its a 750W MS-Tech PSU and that's about as much as I know about the it.

I know there's probably some post regarding this exact question but I'm really in a hurry as I need to call the guy that's selling it tomorrow noon-ish time (around 12-13 hours from now). Thanks In advance.

In theory if you were to get a dual molex to PCIe it would work.

But I deliberately did not mention that as an option because to do that would assume that this power supply is capable of delivering continuous power to its rated specification, and I just don't think it's capable of it.

To give you some perspective (and I'll assume the sticker is accurate for a moment), your 750w PSU is only capable of delivering 456w on the +12v rail, so it's more like a 450w. Then we see it only has a single 6 pin connector (75w), so in practice it's more like a 350w. Even a budget PSU like the Corsair VS450 has two 6+2 pin...
Actually the two +12v rails provide 38a combined. The issue is that your psu only has a single 6 pin and the 660ti needs two.

I dont know what price he is selling it for but maybe have a look at the newer 10 series cards as they are much lower power than the 6 series

well, thats a shame. Probably wont have the money for a new psu for a while. A descent 500W psu around here is ~80 euros which is almost what Im paying for the gpu.

Best case scenario is you try it and it works.

Most likely scenario is you try it, it works for a short time, then your power supply goes pop (and hopefully doesn't take out your motherboard along with it)

Worst case scenario is it catches fire.
