I have zero experience with building my own PC, and I need help with finding the right power supply for this system. Also I’m not sure about the video card and I just want to check if all components are compatible and if there are some improvements that can be made.
Budget: $1050 (€850) OS not included
PC primarily for gaming, planning on doing some basic overclocking
1. Not sure if I should get the Club 3D HD 7870 XT JokerCard
The 7870 XT seems to be really underpriced, I’ve seen benchmarks where it beats the 7950 and the GTX 660 Ti, and that for the same price as a GTX 660.
But I probably want to run XFire/SLI in the near future, and I’ve read things about the 7870 XT not scaling that well. Also, it runs quite hot. So, should I get the Club 3D HD 7870 XT or not?
2. Which PSU should I get?
The System Requirements for the Club 3D HD7870 XT are
“Minimum of 500 Watt or greater power supply with two 75W 6 pin PCI Express supplementary power connectors” (http://tinyurl.com/cf9khtp).
Like I said, I probably want to run XFire/SLI in the near future, And I prefer not to buy a new power supply when I want to buy my second video card. So I need a reliable PSU with enough wattage and 4 6-pin connectors.
Found this one on the internet, but I can’t find any reviews of it. It seems to be Europe only.
PSU: Cooler Master B700 700W http://tinyurl.com/csm7m5v
3. Is everything compatible and which improvements can be made?
Just checking if I didn’t make any beginner mistakes ;-)
1. The 7870 XT is a great deal. But if you want to run with two graphics cards, Nvidia are better at the moment.
2. Don't focus on the PSU requirements, they're kinda useless. They provide a higher number than you'll usually need, so they're on the safe side.
Cooler Master aren't known for good power supplies; the only ones I'd consider acceptable quality are their Silent Pro series. But they're often too expensive anyway.
NCIX has a good deal on an XFX 750W Semi-modular PSU.
3. Faster RAM. No reason to buy DDR3-1333, 1600 costs about the same. You might want to consider a motherboard with more power phases if you want the best OC performance. The Asrock Z77 Extreme3 for example.
