I have some questions on using PowerStream 520W on a 24-pin EPS12V Dual-Xeon (Nocona) motherboard (ASUS NCCH-DL minimum PSU rating EPS12V 600W). Maybe someone can help
OCZ PowerStream 520W PSU Product Specs PDF
Q1 : What are the power implications of using only the 20-pin ATX connector + 4-pin ATX12V on a EPS12V ASUS NCCH-DL?
Q2 : If 2x Powerstream 520W are used :
1st PSU connected to 24-pin EPS12V & 8-pin ATX12V supplying power to the Board + Dual-Xeons + CPU Cooler
2nd PSU supplying power to 2x HDD + 1x DVD+RW + 4x Vantec Tornado Fans (via fan controller) + 4x normal case fans
Note : 2nd PSU is powered-ON permanently by shorting 2 pins on the 20/24 pin connector (forgot which pins, need to find it), ON-OFF is achieved by the switch at the back of PSU
Will this configuration be OK? Or should I just use 2 PSUs jumpstart by 20-pin ATX12V adapter (pic below) and plugging both 4-pin ATX12V into the 8-pin connector of an EPS12V motherboard?
EDIT : BTW, which of these PSUs would you recommend for OC on a dual-Xeons rig? EPS12V : OCZ 520W/Antec 550W/Enermax 660W? Are Enermax's dual-rails (+12V) good for dual-Xeons?
Thanks for the replies.
The ATX power header with only two wires is to jumpstart the secondary power supply unit
