I have an ecs (elite group) k7s5a pro motherboard. I have been leed to believe that this is a very power hungry motherboard that requires more power than your average mother board. I'm running the following
amd athelon xp2400
2 256 mb ddr 2700
agp radeon 7000 64mb
soundblaster 512
pinnacle pctvpro card
us robotics performance pro modem card
two maxtor hard drives
network card
liteon 851s dvd burner
maddog dvd rom
I have been running a deer (yea, I know, it's a cheapo) 300 watt power supply with 3.3v-20A, 5v-30A, 12v-10A
The system tends to crash but not too often. I think it hapens the most when I start copying a dvd. Most of the time it copys ok but it sometimes crashes (and crashes at other times). I think the power supply is the problem. I emailed ecs and they said 300-400 watts with 28A on the 3.3v. I emailed them again trying to get more specific info and they just said use a 400w or 450w power supply to be safe.
I intend to add a siig raid card and two hitachi hard drives. I already spent all my spare money on the card and drive just to discover that the case and power supply were not really up to the task. I got an antec plusview 1000amg which has lots of room, bought round cables and extra fans (the old case only had 1)so I'm pretty broke. I still need a beter power supply.
I intend to run two power supplys. I made a small circuit board with a 20pin motherboard power conector, a 4 pin conector, a relay, a resistor with a small heatsink and a conector for an led so I know the second power supply is powered up. This should allow the first power supply to turn on the second power supply and provide load on the 3.3v (5v and 12v will get load from drives). I want to get a enermax eg375 350 watt power supply that rates at 3.3v-32A, 5v-32A, 12v-26A. It has 185 watts for the 3.3v and 5v so if it is running 32A on the 3.3v, it should have about 16A left on the 5v (max). Acording to the watage it should only have about 14A avalable on the 12v so I don't know how they rate it at 26A. Perhaps it can share power between all three voltages so it can do 26A if not all the 3.3v and 5v are used.
All the enermax has to power is the motherboard and attached components plus a drive or two. I can run most of the drives (particularlly the power hungry dvd drives) and fans off the deer power supply. I would like it to be a little bit overkill just to guarentee enough power to the motherboard and attached components but money is very limited. Does anybody think that the enermax is too small with all that stuff on the motherboard or will it be plenty big enough. It was running (though prone to crash now and then) with 3.3v-20A, so 32A should be plenty, right?
Fyi I chose enermax because they seem to have higher amperages with 3.3v (with a little cost to the 5v) than many other power supplies and they seem to be decent quality (compared to the cheapo ones anyway). If I have to get biger than 350watt I will but I cannot even afford the 350watt right now.
Any opinions would be greatlly appreciated!!
