How many watts do I need?

post #1 of 9
Thread Starter 
Im helping a friend build a PC, nothing specials but just want to make sure he has enough watts while keeping in his budget.

This is the PSU Im recommending to him:
http://www.newegg.ca/Product/Product...82E16817371016

Also, he will NOT be overclocking the CPU, RAM or GPU

  • i5 760 Quad Core
  • Corsair Nova 32GB SSD
  • LG Bluray DVD-RW Combo Sata
  • HIS HD 5770 1GB
  • WD Black 640GB
  • Gigabyte P55-USB3
  • 2x4GB DDR3

What do you guys/gals think. Will he be fine with the 550w?

400-450 quality unit

That rig won't take more than 150-200W, imho the 550W PSU is overshooting it a little bit. The problem is at idle the rig wouldn't take more than 50-60W and that's below the 20% low efficiency threshold of PSUs.

My choice would be an Antec EarthWatts 380W that would provide enough power even if he decides to OC and add a second 5770 for Xfire while offering good efficiency @idle.

This will do just fine.

That BP400 Plus is just a 'meh' 400 watter with realistic load patterns.

Notice how it can only do 384W on the 12V, thus making it a 400W power supply by modern standards.

The Neo Eco 400W would indeed be fine, but the Neo Eco 520 is cheaper after shipping, so that's my recommendation.

By all means, get the 520.

It's just a rebranded Seasonic M12 II 520.

Really unbeatable stuff for the price.
