power requirement for Q6600 rig?
 

Hi,
I assembled a Q6600 G0 + Gigabyte P35-DQ6 + Gigabyte 8600GTS Silent + 1 stick of Crucial PC6400 Ballistix, coupled with a (nominal) 370W PSU (170w on +3.3/+5v, 192W on +12V). No dirves whatoever, just the minimal config to test power on.

When switching on, only the fan in the PSU and the leds on the DDR2 confirm that power is flowing.

Is the PSU inadequate? If yes what would be the minimal requirement?

Thank you

Do you have a 24-pin native connector and 8-pin EATX power connector on that 370W PSU?

an 8-pin EATX power connector? What is that? It's a standard, vanilla PSU

There is a 20+4 power connector and the usual complement of connectors for drives.

Now that you mention there is a strange (for the location) male power 4 pins as in hard disks soldered on the MB (yes!).

I'd better read carefully the manual :D

looking at the manual (first time) I noticed that there seems to be two extra power (?) connectors :wow: compared to "normal" ATX MB I've met, but no EATX.

A 8 pins connector marked "[FONT=ArialNarrow]ATX_12V_2X" and the aforementioned 4 pins "hard disk" male connector marked [FONT=ArialNarrow]"PCIE_12V" :?? [/FONT][/FONT]

[FONT=ArialNarrow][FONT=ArialNarrow]For sure I have not connected the 4 pins connector, as for the other, is it necessary?[/FONT][/FONT]

I think I found the culprit: the PSU. In the manual it's marked that it won't boot if the 2x4 12v plug is not connected and that they recommend at least a 400W PSU... :eek:

Another 135 euro disappearing for a Fortron Epsilon 700W...:no:

EATX 8-pin on the left, 24-pin ATX on the right



Most modern Intel motherboards require those to be connected before the system will work correctly.

You don't need 700W, 500W will do, look into Seasonic models for good efficiency rating

depends, with a strong GPU and the Q6600 overclocked 700W would be appropriate


and you can't tell me a G0 Q6600 with the DQ isn't there to get overclocked a lot

Just a reminder, most games use only 1 or 2 cpu cores, and IE, Firefox, Word, Powerpoint.... isn't really stressing the CPU, you can have all of that openend in a dual core setup without pushing the Quad Core CPU to 100% load. This means that in almost every case you will either heavy load the CPU, or the videocard, but not both at the same time.

Besides that, from experience I know that a Q6700 @ 4,8GHz with dual HD2900XT pulled around 700W with few synthetic software programs running at the same time, with normal air cooling and a single 8600 you won't come even near those results, 500W should really do it.

Even in heavy use of 3D CAD system of multi million $ project, Quad core is loading less than 50% usage. It is purely a waste of equipment resource simply to play a computer game once a week. Unless, you play it so well, but when you do; game is over in hours. :)

AutoCad does use all the CPU resources, ask Thorgal;)
