Hi, I'm trying to install a gigabyte GeForce 1060 into my PC. After snapping it into place, I was sad to see that my psu doesn't have any 8 pin ports. I'm not sure what to do, please give me some suggestions. Here's a link to some pictures:

I'm not experienced in building PC's so I'd like to avoid buying a new psu since I would have to connect everything.

Didn't know this existed. It should work fine provided you have two, unused MOLEX connectors. I think the actual max draw is roughly 140W so that's likely about 60W over the adapter (and it's rated for at least 150W).

Your PSU again has about 430W available on the 12-volt rail. Probably you'll use no more than 300W total for the system unless you've got an overclocked AMD setup in which case I'd definitely go with a better PSU.

Lots of people get scared of adapters but they are still just WIRES that draw power from the same source. Your PSU was probably an older one which avoided more GPU power cables because CPU's could use a...
Hi,
ADAPTERS can be perfectly acceptable, though we'd have to know your:
a) PSU, and
b) CPU

We can then calculate how much power is needed by the system. If you only used 250W total including the GPU then any 400W+ PSU should be fine.

For example, a 2xMOLEX-> 6-pin uses the same 12-volt source anyway. However, to get 8-pin you'd have to have at least 6-pin so you'll end up with TWO adapters.

#1 to get 6-pin
#2 is 2x6-pin to 1x8-pin

*I see about 430W on the 12-volt rails. It's pretty much certain you have sufficient power.

**What ADAPTERS did you get with the card?

If you got a 2x6-pin to 8-pin, then you need to buy a 2xMOLEX-> 1x6-pin.

SUMMARY:
Okay, the card does NOT come with an adapter. Thus you'd have to buy TWO adapters. At that point though, I'd suggest just getting a PSU with an 8-pin (or 6+2)-pin output as that will be less messy and only cost a little more once SHIPPING etc is factored in.

Keep the PSU you have now stored in an anti-static bag so you can use in case of PSU failure later.

I'll post this then link a PSU.

Lots of people get scared of adapters but they are still just WIRES that draw power from the same source. Your PSU was probably an older one which avoided more GPU power cables because CPU's could use a lot more power. They design PSU's to be as idiot-proof as possible.

So they estimate the WORST CASE for CPU power draw then only allow PCIe GPU cables to use what is left over.

IF that still scares you then here's two choices:

$90 http://pcpartpicker.com/product/9q4NnQ/evga-power-supply-220g20650y1

I chose Semi or Fully modular to limit wire clutter. The EVGA has an ECO MODE which I would recommend. It will disable the fan if you are under 325W (probably all the time).

You can consider a quality PSU an investment. I have the 750W version of the G2 fan and the fan is too noisy BTW for my tastes which is why I use ECO. I suspect the Corsair above has a much quieter fan.
 
Solution
I wouldn't use an adapter with an Apevia power supply, but that's just me. By the way, an EVGA 430W power supply can be had at relatively low cost.

It's not hard to swap out a power supply. The cables are all the same, and go to the same places. Take lots of pictures, so you'll remember which cable went to which plug on the motherboard and to your hard drive, etc. Watch a couple of Youtube videos to see how it's done.

You spend a couple of hundred dollars on a nice videocard and you can't be bothered to use the right power supply? Come on.
