Issues with power draw on Z77 FTW

post #1 of 3
Thread Starter 
Ever since using my active mini displayport adaptors my motherboard has be having trouble powering all my usb ports properly. I'm not sure if it's the 5 volt rail on my PSU not being able to provide enough power. I would assume these would only draw 0.5 amps and not cause too much of a problem. Anyone have any suggestions?

By the looks of it I may need to get a bigger power supply that has 7 6/8 pins on it rather than the 4 I have right now. That way I could use the secondary aux atx 8 pin and the secondary 6 pin pci, and use a non double molex to 6 pin for the primary pci. Thoughts anyone?

The problem seems to be that I need a 1500 watt psu to do this.

What are the mobo problems you face when filling up the USB ports? (I'm assuming you use every USB port, so around 10 USB devices)
Without sounding smug, it could be a simple USB drivers issue (with W8). But whatever problem(s) you're having, a 1.5KW PSU is not needed to resolve them.

Solved it, turns out it was a few problems. Mainly a a bios flash issue from about a week ago I resolved by trying out the bios b switch. And also an issue with a bad driver installed for a aux usb device. Reflashed the bios after testing on the b bios switch and removed the device and now things make sense again.

All that being said, at some point I should upgrade my psu (to either dual 750s or a 1200) as a double molex to 6 pin looks terrible.
