Intel s5520hc motherboard measurements

[Tamikanottammy]

What is the dimensions in inches of the intel s5520hc mobo. It’s a ssi eeb mobo I believe. I’m specifically asking the distance between the two 8 pin power supply connections. I need to figure out if I should get a 6” power supply adapter or an 7”. I have one of each in my shop somewhere

Also how long should the 8 pin cable on the power supply be if my psu is located near the top-center of the board? It’s open frame custom chassis I designed it so anything can go almost anywhere! Abiet minor mods or tweaks
