System Name Obsidian Tri-Fire
Processor i7 3770K De-Lidded @ 4.7GHZ
Motherboard Asus Maximus IV Extreme - Z
Cooling Custom Loop Cooled - Supernova 1260 & 360 rads / D5 pump
Memory 8GB DDR 3 @ 2520Mhz
Video Card(s) 3x AMD 7970's @ 1250/1900
Storage 2x 240GB OCZ Vertex 3 SSD. / 3x 1TB Seagate HDD's
Display(s) 3x 24" 120hz BenQ's running 5760x1080 Eyefinity.
Case Corsair Obsidian 800D
Audio Device(s) MOBO
Power Supply XFX 1250w Black Edition PSU
Software Windows 7 64 bit.
Benchmark Scores Coming soon.
Now my water cooled rig is up running and stable, I thought I would offer some info I have recorded thats kind of interesting.

During benching and gaming, I have been creating a spreadsheet of everything I do and that includes power draw at the mains outlet. I was very surprised to find that most games dont stress the PSU anything like benchmarking. I thought the figures would be much closer.

The Test Rig: (For power consumption reference)
  • ASUS Maximus IV Extreme-Z
  • i7 2600K @ Std settings
  • 3x AMD 7970HD in Tri-Fire @ std settings
  • 2x 240GB OCZ SSD's
  • 3x 1TB Velociraptors
  • Corsair Vengeance 8GB DDR3 @ 1866
  • XFX 1250W PSU
  • 1260 & 360 Radiators fed with D5 pump
  • A few lovely lights... lol

Results as follows:
(All settings maxed for each game, using eyefinity at 5760x1200)

  • 3D Mark 11 (Performance) – 880w
  • Heaven 2.5 – 898w
  • 3D Mark Vantage (Performance) – 906w
  • Furmark on 3 screens – 908w
  • Aida 64 stability test - 1092w

  • Mass Effect 3 - 565w
  • Shift 2 unleashed – 570w
  • Syndicate – 580w
  • Skyrim – 620w
  • Hawx 2 – 641w
  • Alan wake – 720w
  • Crysis 2 – 780w

There is little point to this topic, other than to show that during gaming, your PSU may not be quite as stressed as you think. Its during benchmarking that you need the extra watts for synthetic loads.

Please Note:
These figures were taken with everything at standard clocks so its a valid benchmark. Overclocking will increase the current required.

Nice rig and test.

The results in gaming make me think, 1 of the 7970 sleeps in game mode that's for sure.

A bit more specific please.. Model number etc?
Without real-world PSU efficiency numbers etc. of the PSU, the results aren't really accurate.
