So a few months ago I bought the parts for my first PC build. I Got:

CPU: AMD Athlon II X4 750K 3.4GHz Quad-Core Processor

Mobo: MSI FM2-A55M-E33 Micro ATX FM2 Motherboard

RAM: G.Skill Ripjaws Series 8GB (2 x 4GB) DDR3-1333 Memory

HDD: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive

GPU: HIS Radeon HD 7850 2GB Video Card

Case: Cougar Spike MicroATX Mini Tower Case

PSU: Corsair CX 430W 80+ Bronze Certified Semi-Modular ATX Power Supply

So after getting these parts, and putting them all together I noticed that my PSU didn't come with enough/the correct wires for my GPU. The GPU needs 2 6 pin connectors and my PSU didn't come with any. But when I went online to buy some I didn't see any. I made a post on reddit.com/r/buildapc, and somebody there told me to buy 2 of these

But I have no idea how those would help me, I'm not sure where they would plug in on my GPU since there's clearly nowhere these can plug into. I asked him but got no answer. You guys over here seem like you know what your talking about. So what wires should I buy to be able to plug in my GPU? I was looking at this

but it says extension so I don't think that's it but i'd much rather ask some people who actually know what they're talking about. Also the guy over at reddit.com/r/buildapc told me that my PSU didn't have enough wattage to power my GPU and that I should get a new one. But after doing some research on that people were saying that a 430w PSU was fine. So should I upgrade my PSU too? Because I don't really have the money for that. Also sorry about the long post, I feel like i've been rambling haha, but i'm sorta getting frustrated feeling like I wasted my money on my PSU.

If you bought that PSU new, it should have come with 1 x PCIe 6/8 pin cable. But the HD 7850 you bought is one of the few HD 7850 that requires 2 x 6/8 pin cables. The Molex to PCIe 6 pin that the person suggested to you is the best option short of replacing the PSU.
The adapters connect to the Molex connectors from the PSU, and then to the card.
 
that PSU SHOULD come with at least 1 6+2 pin. So it can be used either as a 6pin or a 8pin power connector for a video card.

This video card should only require ONE connector. If there are two its the first 7850 I've seen with two.

Also this Video card requites at least 500 Watt PSU. You need to check requirements for everything before you buy!
