I was about to purchase a monitor for my HP Pavilion 570-p033w desktop computer to plug into the onboard HDMI graphics. My main concern is this computer only has a 185W PSU and wanted to make sure I didn't get a monitor that would eventually cause issues due to power drain from monitor. I'm looking at the ASUS VS228H-P 21.5" Full HD 1920x1080 HDMI DVI VGA Back-lit LED Monitor. Thank you.
