Hello,

I am planning to do my first build sometime in May. Here are the specs:

Core i7 3770k
Crucial Ballistix Sport 16GB DDR3-1600 RAM
HGST Deskstar 7K1000.C 1TB 7,200 RPM Hard Drive
Zotac ZT-60405-10L NVIDIA GeForce GT 630 Synergy E 4 GB
ASRock Z77 Extreme4 LGA 1155 Z77 ATX Motherboard
Thermaltake Silent Intel LGA1156 CPU Cooler
Lite-ON 24X SATA DVD Burner

I don't really know how much power I'll need, but I read that the video card will need at least 300w.

^I like this one, but are refurb PSUs bad?

Any suggestions? I'm trying to keep it under $80. Thanks in advance!

your build is not balanced at all you have a fast processor with a slow video card
downgrade the processor to 3570k and get a better video card like 660ti, 670, 7870
with power supplies you should get 550-650watt psu, dont get refurb ones. Get a trusted brand one such as Antec or Corsair. Don't cheap out on the power supply because if its low quality it can short circuit and destroy all of the parts its connected to

That is a good deal, but quite a bit more PSU than you need with this rig unless you plan to go the multi-GPU route in the future.

Refurbished items are generally as good as new. For the cost, this is a good purchase.

I typically recommend getting a Seasonic or Corsair PSU. In this case, for the cost, I think this is an acceptable alternative.

i second both alvine and COLGeek's posts, a beefier graphics card is in order for the other specs you've posted. as far as PSU goes, this link might help you get a better idea of what wattage you're looking for. the other thing while selecting a PSU is the 12v rail power requirement of the graphics card. if the card calls for at least say, 30Amps, then make sure the 12v on the PSU can supply at least 30A
