PSU Upgrade?

Hardware Hub PSU

Hey all, Moist here, new to these forums :3

So I built my first PC a couple of months ago with almost little research and I was wondering if I should upgrade my PSU.

My build:

i5 3350P  

AsRock H77M

8 GB of DDR3 1600 MHz memory

HIS Radeon HD 7870 GHz Edition

500 GB WD Caviar Blue HDD

all wrapped up inside a Cooler Master Elite 430 case 

And the main reason for this post: my 450W XFX Pro Series 80 Plus Bronze Power Supply

 

Is this psu enough to power my build? And do I have some headroom for stuff like adding another hard drive?

Thats plenty for your build.

So if I were to throw in another hard drive, I could do so without upgrading?

Yes, that's plenty of power.  Your current build will only consume about 325 watts, and that's being very generous. HDDs only use around 10-20 watts, and SSDs use MUCH less.  You'll be just fine either way.

This reminds me, I may need to add another HDD to my build soon.  My 500GB is filling up fast.

Absolutely fine, as Ares said. Your system may even consume under 300W because of your low-power non-overclocked CPU, so I can't imagine a 450W unit being stressed too much by adding a few more HDDs.
