how do I know what connectors and amps I need?

[Tommy154]

This is my first build and I'm not sure how to choose my psu. build: http://pcpartpicker.com/p/3d0iL
Currently looking for a 700-750 80 gold. I found some psu with their compatibility filter but I'm not 100% sure its correct.

From the manufacturer's website I know the GTX 770 needs 2-8pin connectors, but a lot of those recommended psu just say they have a bunch of 2 and 6 pin PCI-E and some just say they have PCI-E but don't specify the pin numbers. I also can't how much amps I need on the rails. I don't see anything on Gigabyte's site saying how much amps I need http://www.gigabyte.us/products/product-page.aspx?pid=4692#sp

Can anyone help me out and help me understand how to find this info? Thanks in advance

Now a days almost Every PSU Comes with 2 & 6 Pin Connectors,If your Graphics card need 8 pin Connectors then Use as 6+2=8 & If has only 2 then put 2 pin connector

http://www.gigabyte.us/products/product-page.aspx?pid=4692#sp in reference to the 5th imagine, the connectors are all the way to the right. I can use a 6 and 2 pin connector even though the 8 pin connectors are keyed like that? Also how do I know if I'm meeting minimum amp requirements on the rails? Does pcpartpicker look at stuff like this when showing compatible parts?

This should do just fine for what you need. It is a quality Power Supply built by Seasonic. I have taken your build and added the PSU to it.

Have a nice day, and good luck with your build!

This one would be plenty of power for your build. 700w is overkill (even 620 is alot, but it's on sale lol) and there may be $0.25 difference per month in electricity between 80+ gold and 80+ bronze. 80+ efficiency only is relevant to miners and corporations trying to save every penny.

The 770 wants around 30a on the +12v rail, and this PSU easily gets you there, with plenty of room for overclocking and longevity, and is a top-quality product: http://pcpartpicker.com/part/antec-power-supply-hcg620m

Here's a build, including power supply. You don't want to overpay and overvolt for that RAM, it's not going to really be any improvement. And for the same money you can get the much better 780 too:

Ah, that's something I forgot. If it's not being used for extensive video editing or similar tasks which the i7's hyperthreading would speed up, the i5-4670K is a great CPU for gaming.

Your Graphics Card Power requirement = at least 600Watts (with two 8-pin external power connectors).Your Graphics Card has 8 pin * 2 Connectors.

Get any 600 + PSU will be ok for your system & Come with 2 * 8 pin Connectors for your GPU

There are two Revisions of the GIGABYTE GV-N770OC-4GD.

GV-N770OC-4GD (rev. 1.0)
• Power requirement: 600W (with one 6-pin and one 8-pin external power connectors)

GV-N770OC-4GD (rev. 2.0)
• Power requirement: 600W (with two 8-pin external power connectors)

For a system using a single GeForce GTX 770 graphics card NVIDIA specifies a minimum of a 600 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 42 Amps or greater and that has at least one 6-pin and one 8-pin PCI Express supplementary power connectors*. Some of the non-Reference Design GeForce GTX 770 cards have two 8-pin PCI Express supplementary power connectors (e.g. GIGABYTE GV-N770OC-4GD (rev. 2.0), MSI GTX 770 Lightning, MSI GTX 770 TwinFrozr Gaming).

* Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.

A system power supply maximum combined +12 Volt continuous current rating of 37 Amps or greater is more realistic based on the actual measured power consumption of the GeForce GTX 770.

You won't see over 350w of peak power draw from the entire system with a 770: http://www.anandtech.com/show/7492/the-geforce-gtx-780-ti-review/15

42a is definitely not the minimum from the 770, the 30a I suggested above was already conservative. A system drawing 350w requires right about 30a. Any 500w+ PSU built by a reputable brand will supply at least that, plus some.
