Can I get away with a good 300w PSU on this?

Maybe, but not recommended, you should have a PSU that provide AT LEAST 18 A in the +12 V rail.

I have not done this configuration. However, when building a system you should find the sum power requirements of all your components. Then use this figure to choose a power supply greater than this number. I would not use a 300w power supply for a 300w graphics card

You need around 700W for your setup, so 750W from this unit should be more than enough... keep the brand in mind though, going Corsair is a safe bet because they advertise the power the unit can handle continuosly, and not the peak wattage it can reach, this is a great PSU for your setup... :)

Go with a quality power supply like a 300w seasonic and you'll be fine. Always go name brand on a psu. Never go cheap. A 430w power supply will give you a little overhead to add a graphics card in the future if you want to do dual graphics, but even 430w will be overkill if the card can run off of the pcie bus.

It's really more complicated than that, the card itself is 60W TDP (Thermal Design Point). You must consider your system's makeup -- i.e. processor, expansion cards, USB devices, drives, # monitors, and memory. Try searching on "power supply calculators" to see.That said, this card's TDP is so low, most systems should run it fine. A 300W PSU with an i7 CPU and lots of peripherals might have issues.

Yes definitely, and if you don't trust me or anyone else here, go to pcpartpicker.com and put in all the parts to see the estimated wattage. This PSU has 80% bronze efficiency so you should leave around 150W just to be safe.

Yes. A good quality 800w power supply would be enough. Just make sure your psu delivers at least 70A on the 12V rail.

Yes it will. It may say 350W supply but you can get away with 300W with little to no performance drop off.

I have a 300 watt PSU with stock 8 gb of ram and an intel I5, and it runs it perfectly fine, but I will be investing into a new PSU, just for future possible upgrades.

I suggest you buy a converter which supports power at least 3 times larger than what you really need, this will make you less trouble. Thus for your PS, 500W seems good enough.

No. If a power supply says it's 300w, you will actually get less than that.

Absolutely. If I'm not mistaken, the stock psu is only 300 watts in the HP. Although, you may want to check to make sure it has the proper cables.

I cannot find requirements on the power supply, I personally have a 500W unit. I have no reason to think a 300W would not work. You should be good.

I don't know the exact wattage requirements for your setup (you have to take into account the number of fans. CPU cooling, number of hard drives and optical drives, etc). But an 850W PSU is almost certainly enough for your rig. You can check out some websites like: powersupplycalculator.net to double check. But I'm 99.99% sure you will have PLENTY left over with an 850W PSU.

Yes, should work fine. My Desktop had 500W in it when I was using this. It will be a VERY tight fit in that case though.

Can't say 100% but I'm using a 550w PSU with an i5 2200 and everything's fine. A 500w would be plenty.

"It depends." Here's the long answer: Read the label on the side of your power supply about the total watts available on the combined legs of the output. Now add up the power used by all your components--use google to find that information, or check the manuals. If the total is less than the legs, it is certainly worth trying.This is the short answer: If this 300-w. PSU is one of the 'no-name' ones that came with the case for $39.99, shipping included. It most assuredly will not. (At least for very long.)
