Please help me to figure out what is the diff between this 2 power supply from Thermaltec
1- Thermaltake Toughpower W0156RU 1200W ATX12V / EPS12V Power Supply
2- Thermaltake Toughpower 1200W Psu
Please please. The diff in price is around $ 7
If I get into wrong place for post this question, Please forgive me.
