You reminded me that early 28 nm and early GCN were both a big oof in terms of power consumption. The 7970 was exceptionally bad in that regard, a typical AMD GPU flagship clocked way above its optimal power-frequency curve. |
Crossfire systems with up to 1000 Watts:
"A 1,000 watt power supply should be the minimum to ensure stable operation. In the case of the Radeon HD 7970 GHz Edition, however, even this is not enough - especially when overclocking. We ourselves opted for a 1,600 watt power supply after the system could not be operated stably in extreme situations with a 1,000 watt power supply."
