Bought myself a Brand new Asus Radeon HD 7770 GHz edition with 2GDDR5 Video Memory.
Along with this I upgraded my power supply to a Rosewill "capstone" 650W power supply with it.

Now the Power supply is booting everything up, CD/Bluray drives work, hard drive is spinning other board lights are on, CPU fan is working, everything. However, Nothing graphics-wise is working. I took out my old Radeon HD 5450 512MB DDR3, and put in my new 7770, and made sure everything was plugged in.

A red light came on the graphics card and I noticed there was no display, Realiziing I forgot the PCI-express power component. I plugged that in, and there was nothing displaying still.

Along comes the troubleshooting: I've tried to plug in VGA-DVI port, then the DVI port, then the HDMI port, then I tried the on-board graphics from the motherboard, DVI and VGA ports while the card was plugged in, and even when it wasn't.

And then finally I tried to plug in my old card into the computer, and run that with DVI like I used to, and nothing. Now there's no display.

My experience with computers I would categorize as Knowledgeable, but this is starting to frustrate me. Any help would be glorious.

My computer is specified as this one: http://tinyurl.com/o6ppenv
Everything is original and these are the first upgrades I've decided to make.

EDIT: This is an album I made to try and make everything a little more "visual"

Everything is plugged in accordingly, The new power supply came with a 20 pin connector, and it has a 4 pin extender to plug into a 24 pin port (which is what I have on my motherboard) so I plugged in all 24 pins. On the other side of my CPU there's a 4 pin slot to plug in the other 4pin connector straight to the motherboard, and that is plugged in as well.

(There was only one of these on the old 300W power supply, however the new one has two, one Labelled "CU" and the other labelled "U1" I've tried them both to avail, and the CU one is currently plugged in.)

CPU fan constantly spins. Monitor works well when plugged into my laptop for an extended display.

There's about 6, 8-pin connections on the back of my power supply, two are occupied by the Hard drive connections and the CD drives. the third is the PCI-E cord. There were 2 of the PCI-E connectors that came in the box, and each one has a PCI-E connector and an SLI-ready connector (as part of the same cable). I've just tried to use the second (spare) wire that the PSU came with, and I'm still not getting a signal to the monitor.

Is this PSU modular? If so is the pci-e cord attached to the correct connector. Also is it inserted all the way in.

The PSU is Modular, yes. It is "clicked" into place, meaning all the way in. and I'm not too sure there's a "specific port" for the PSU, as the GPU is lighting up green, I'm assuming it's plugged in accordingly, otherwise (as stated above) a little Red led right next to it will be glowing instead. I've also attatched an album for a more visual approach: http://imgur.com/a/bBtQH

Since this PSU has 2 pci-e connections per cable there must be 2 places to connect your cables. Try the second port, and yes they should be specific to pci-e. Each port should be marked for a specific cable(2 pci-e, 2 Peripheral and 1 molex)

Nothing is labelled, and all the modular ports look the same, the only thing that is different are the connectors. (IE for an 8 pin connector, only pins 2,3,4,6,7,8 are there)

Unusual, my seasonic has port specific cables. The only thing I can think of is to try your old PSU to see if it works. If it does we can conclude that the PSU is at fault.

I would have loved to say yes, but, once again, everything boots up, but there is no display... With the old power supply and the old GPU. (the new one wouldn't be able to work with the old power supply as there is no PCI-E)
And the old power supply is not modular. Everything's all jumbled up and sticking out of one hole in the back.
to repeat: Old power supply + old graphics plugged in again and it runs, (all fans at full,) but no display.

Turns out the problem was that the computer didn't like change. Upon further help I learned that taking the battery out of the motherboard (looks like a watch battery) and leaving it out for a minute and then plugging all of the new stuff in (with the same battery put back in) will "reset" the BIOS to the MoBo's default settings. After which a quick boot for the system proved successful, the HDMI outputted perfectly to the monitor and all ended well.
