I recently bought a Gigabyte Radeon R9 270x for my computer and I tried installing it, although... I don't know where to plug it into my PSU (Win Power, Model: ATX-550L, Max output: 550W)

Problem 1: I have no idea where the cables from the graphics card plug into the graphics card itself! I can't seem to find where they go without pulling the graphics card out
Problem 2: I have no idea where those cables would plug into Power supply.
Problem 3: I'm pretty sure that my PSU doesn't have enough cables to support my graphics card

Please Help!

Ok, so now what you have is two, 2x molex to 6 pin adapters plugged into your gpu. So you can now plug each of those cords coming out of your gpu into a molex connector found somewhere inside your pc. It does seem like you may in fact have an inadequate power supply :/ i can't really tell without being able to dig around in there myself

Ok, first, makes sure you have uninstalled the previous graphics card. you will also need to take off the back panel in order to locate the other possibly unused power connectors. They will be the thicker ones , but not the BIG thick one coming out of the psu. There should be hopefully 2 6 pin power connectors. If it has at least that, then you will be fine, if you only have one 6 pin, or just one 8 pin, then you are out of luck

If you have two 6 pin (means 6 holes on the plug) then if i remember right, you should have a compatable power supply, just plug and go.

If my memory is NOT right, and you need an 8 pin AND a 6 pin to power the 270x, then you will need to buy an adaper that is usually labeled, 6pin-8pin pci power adapter, or something along those lines that will have a female 6 pin on one side, which you plug the 6 pin from your psu into, and an 8 pin on the other side, which you would plug into your gpu

If that doesnt help out feel free to ask. No one is going to make fun of someone who just simply doesnt know what to do inside a computer.

from looking up your psu, it appears that it SHOULD have two 6 pin connectors coming out of it. you will need to find these

and also according to the interwebs, your graphics card should require those 2 6 pin connectors.

So unless the internet is lying, you should be fine unless somehow one of those 6 pin pci connectors is being used somewhere which no one but you will be able to find out, and you will have to do so by looking

That's the main problem, My PSU doesn't even seem to have ONE 6 pin. Everything that comes out of the PSU case is already plugged into something else.

also, imagine looking at your graphics card in the Fans towards your face position. from there the place where you need to plug in the cables will be on the right hand end of the card (opposite end of the hdmi port n stuff, and should simply look like two, 6 holed sockets

Then you will need to find each one. Your power supply should have 1 24 pin (the massive one), one 8 pin (the one plugged into the top of the motherboard) and two 6 pin connectors (these would have been plugged into the old gpu likely or hidden somewhere behind the motherboard since they might not have been used

now, i can't find the exact model you listed, so that may be a problem. But you should be able to look at the power supply, see all the cords that are either routed in front, or behind the motherboard, and follow all the connectors and be able to list them all off. there shouldnt be too many, but it may look like a mess depending on who built your computer

It looks like your specific model of PSU does not have PCIE connector(s) (from those pics, I didn't look up the specs- very weird). Also that card has PCIE to Molex adaptors on it. Hopefully you can disconnect those. It looks like it might be a good time to upgrade your PSU.

Just my two cents.

Well then, any suggestions for a PSU that will definitely do what I need for a cheap enough price?

I'm definitely not the person to ask about PSU's that are "just good enough" as I firmly believe that a good to very good PSU is the only way to go. Having said that here are a couple I would recommend

That is the lower end of a very reliable manufacturer. It can do what you need without question and should you decide to build a new computer anytime soon you can use this PSU to start.

Here's another: http://www.newegg.ca/Product/Product.aspx?Item=N82E16817151096
This unit also will do exactly what you need and this brand is the most respected name in PSU's. A little more expensive but you get what you pay for.
