So, I have an Inspiron 620 and I'm looking to add a GTX 760 and an extra terabyte of storage to it because the current specs, which I will include here, are very poor by typical PC standards. Although, I need to know, what's a good power supply I can get for it that'll be able to support the GPU I have in mind along with an extra 1 TB hard drive?

Here is a list of my specs.

And here is a picture that looks exactly like the computer I have.

I'd prefer it to be affordable, yet a small price raise to get good quality is okay.

Your Dell case will likely only physically "fit" a proprietary Dell PSU, not the aftermarket standard ATX sized. It will probably be a close fit, with the power plug or power switch blocked by metal; with most of the screw holes lining up. I "fixed" my old Dell with tin snips, hacking away metal.

That allowed me to purchase a good PSU. And after a year or so I upgrade and junked the crappy Dell case anyway. I "carried over" what I could to the new build. Harddrives, burners, ect and of course the PSU.

That got me where I am today. Other than laptops, for years now I've built my own. Make your next investment a quality case. You'll carry a case over for many upgrades(with the PSU), outlasting many motherboard boards, CPU's, GPU's ect...

For a system using a single NVIDIA Reference Design GeForce GTX 760 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors. Some of the non-Reference Design GeForce GTX 760 cards have a single 8-pin (e.g. ASUS GTX 760 DirectCU II OC) or two 8-pin (e.g. MSI GTX 760 HAWK) or one 6-pin and one 8-pin (e.g. Gigabyte GTX 760 WindForce OC, EVGA GTX 760 SC w/ACX Cooler, MSI GTX 760 TwinFrozr Gaming) PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

What is your power supply budget amount? What brands and models are available to you (i.e. brand and model availability differs depending on what part of the world you live in)?

A standard ATX (a.k.a. PS/2) form factor power supply will fit into that Dell Inspiron 620 MT system as you can see here:

When it comes to the budget, what I meant not one that costs more than an average one should. I guess it wasn't really a necessary detail to include. So yeah, sorry about that.
I live in the western area of the US (California) and I don't exactly live near many stores selling PC parts, so of course I'll have to order from online.
Also, I'll apologize in advance if I have a hard time understanding any of this. I've only gotten a simple understanding of it all.
