mithromorning people17:12
CarlFKmorning mithro17:12
CarlFKcrap - i forgot to pick up a PS when I was out yesterday17:12
CarlFKI wish I could ssh to a box and query what sort of PS was hooked up to it17:13
mithroCarlFK: any ATX power supply should work17:13
CarlFKmithro: don't I need something with an extra connection for the 2 cpus ?17:14
mithronot that I believe, I think you just need the extra 12V pin thing17:14
mithroCarlFK: check the manual?17:14
mithrothe CPUs are really low power CPUs, only 80W each17:14
mithroand there are no GPUs to consume power17:15
CarlFKoh yeah... I looked at the website for recommendations and I guess I got lost17:15
CarlFKthe CPUs have some pretty impressive heatsinks17:15
*** Palash has quit IRC17:19
mithroCarlFK: the heatsinks I brought are designed so I can run the system with the fans off most of the time17:19
