As the titel explains, I need your help to find out the value of a broken resistor on my mainboard.
The mainboard is the model Chicony CH-471A (Ver. 3).

The mainboard was shipped in a pretty strong box.. unfortunately this wasn't enough and one edge of the box was completely crushed. 😵
In this corner of the box was the mainboard with the corner where the AT plug and power connector are, and two resistors above the power connectors. One of those resistors is a goner:
All over the board this size and color of resistor is used:
I measured the still available resistors and found two different values, +/-712 Ohm and +/-1150 Ohm. I cannot read any markings on the broken resistor that might have given any clues.
On the other resistors I see the marking SZZ with below it 104:
Now is my question, can I say safe the resistor is +/- 712 Ohm ? Can somebody find something on those markings.
And how much watt does this resistor have to cope with? 1W, 0,5W or 0,25W?
I do have a box with around 70 different values of 0,25W resistors with the 4 color bands on them. There is a 680 Ohm version between them and I hope I can use this one to change with the broken resistor.
I really hope some of you can help me with this and if needed point in the direction of a good replacement part. 😀
