First time builder - PSU recommendations?

This is my first attempt at building a PC. Can I get a few recommendations for a PSU in the $50-$70 range with this set up? If I have to go higher that's fine but if I can get a quality one at a lower price, it's preferred. I'm going to be using it for video editing and some mid to maybe high range gaming. Also does the case size effect the type of PSU?

CPU: Intel Core i5-2500K 3.3GHz Quad-Core Processor

Motherboard: Gigabyte GA-Z68MA-D2H-B3 Micro ATX LGA1155

Memory: Kingston Blu 8GB (2 x 4GB) DDR3-1600

Hard Drive: Seagate Barracuda 1TB 3.5" 7200RPM Internal Hard Drive

Video Card: EVGA GeForce GTX 550 Ti 1GB Video Card

Case HEC 6T18BB MicroATX Mini Tower Case

Optical Drive: Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer

Monitor: Acer G215HVAbd 21.5"

  1. I think a Corsair Builder 430W should do you just fine, even when you add a second card. It's currently $35 after rebate: www.newegg.com/Product/Product.aspx?Item=N82E16817139026
    I'm not sure what to make of that motherboard. How much are you getting it for?
  2. $119 for the motherboard.
  3. That's fine, then. If you anticipate ever going crazy with graphics cards and having two ridiculously powerful ones, go with this one for PCI bandwidth: http://www.newegg.com/Product/Product.aspx?Item=N82E16813157271

    Case size does not affect the PSU. Everything but servers and some OEM builds uses ATX-standard PSUs.

    How much are you actually willing to spend on this build? It would be good if you set yourself a ceiling. If you can fit in a nicer graphics card, I don't think you'll regret it.
  4. $700-$800, I might be below that, will double check the total. I won't actually be doing a lot of gaming, I'm only interested in FFXIV and it seems silly to go big for a single title I may end up not playing. The 550 will be good enough on it I've heard, but my main use for this build is editing in FCP X and After Effects, which it's going to do fine for what I'l be working on.

    Edit: @ somewhere between $710-$720 before my wireless card, speakers, and most likely a new mouse/keyboard. Those are separate from my budget though.
  5. Someone made me aware of the Radeon HD 6850, if I get it, will the 430 PSU still be sufficient?

    Yes i recommend this one though http://www.newegg.com/Product/Product.aspx?Item=N82E16817151093
  7. For a system with a single GeForce GTX 550 Ti NVIDIA recommends a minimum of a 400 Watt or greater power supply with a minimum +12 Volt continuous current rating of 24 Amps or greater and with at least one 6-pin PCI Express supplementary power connector.
  8. Recommending in case I need the extra wattage down the road or you've used it personally?
