My specs are
cpu: i3 4150
motherboard: h81m d2v
gpu: hd 7950
psu: fsp raider 550 watt
2 hdd: 500 gb +250 gb
1 dvd drive

Will my motherboard support an additional hard drive?
Do i have enough power on my psu?

Based on the above specifications you have 4 sata connectors so you can install up to 4 total. I'm guessing with your 2 hdd and 1 dvd drive using 3/4 sata connections you can now then only add 1 more. I've never heard of your psu but based on the 550W rating if it holds true then it should be more than fine.

Based on this list:

Your psu is un-tiered. It is preferred that you pursue as close to tier 1 as you can afford to ensure reliability of power delivery. Going cheap with the psu makes decisions like these more questionable than it otherwise would be. This acknowledged, it shouldn't...
Yes,you can add another HDD on your mobo.
Your PSU should be enough,but it's a low quality one,so there is a possibility of damaging the 7950.If you have enough money,buy a XFX TS 550W PSU,which is a great,very reliable and a commonly used PSU.

Going cheap with the psu makes decisions like these more questionable than it otherwise would be. This acknowledged, it shouldn't mathematically be a problem. However, brand, reliability of components from an un-tiered psu I cannot make you any guarantees but simply put in theory it should be just fine.

Understandable. I'm sure there are many factors that go into one's selection of parts and I meant in no way to slight your brand of psu but it is recommended to pursue higher tier psu's when you are able to. I'm glad you are confident in your psu. We can't all be so lucky to get the brands we want all of the time; as long as it works well for you I'm okay with it! In any case, I'm glad that I was able to help!
