I'm finishing up the design for my new build and now looking for a PSU. According to my graphics card, it looks like I'll need a 500 Watt PSU. Here is my build specs so far:

  • COOLER MASTER HAF X Blue Edition RC-942-KKN3
  • ASRock Z77 Extreme6 LGA 1155 Intel Z77
  • Intel Core i5-3570K Ivy Bridge 3.4GHz (3.8GHz Turbo) LGA 1155
  • SAPPHIRE 100354XTL Radeon HD 7870 XT w/Boost 2GB 256-bit GDDR5 PCI Express 3.0
  • G.SKILL Ripjaws X Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM 1600
  • SAMSUNG 840 Pro Series MZ-7PD256BW 2.5" 256GB SATA III MLC Internal SSD
  • Western Digital WD Black WD2002FAEX 2TB 7200 RPM SATA 6.0Gb/s 3.5" Internal Hard Drive


  • Any recommended PSU that I should look at? I'd like to get something that has modular cables so I can do proper cable management and not have unused cables laying around. Would like something with good energy efficiency. I know Thermaltake has been a good manufacture in the past. Any suggestions?

    Looking around Newegg, it looks like high ratings for a manufacture called Rosewill. I've never heard of them, but it's been many years since I've done a build.

    Thanks for the suggestion. I assume Seasonic is a good brand? When I look at the link, it comes up as XFX, not Seasonic. Seems like I wouldn't need 650 Watt PSU, but I could be wrong. I was looking at something like this:

    What are your thoughts on Rosewill brand PSUs?

    Thanks for the suggestions. What's the best way to determine what wattage PSU I should get? Is there any negative of getting one that's more powerful the necessary (e.g. higher electric bill, damage to computer components)?

    A 500 watt will run your system , but if you want extra headroom get the 600 watt,The ones I listed are Bronze Certified.

    SAPPHIRE 100354XTL Radeon HD 7870 XT w/Boost 2GB 256-bit GDDR5 PCI Express 3.0 < Nice card I have that in my Intel build.

    One of the very few 7870 XT available. Keeps going out of stock, glad it's back in stock so I can purchase. Need to buy soon before it's gone again. Glad you like it.
