I'm looking at a HP PC HPE-510t, this HP PC only got a 300W power supply, how can it run HD 5670 video card, which requires minimum 400W power supply?
The reason why I ask is because currently I have a HP DC7800, which has a 365W 80% efficient power supply. I installed a HD 5670 video card today, and seem running fine on my 365w power supply, played unreal, left 4 dead2 on max settings.
Here's my power supply label: 12A + 14.5A = 26.5A on 12V rail
I'm also wondering with this power supply, can I use HD 5770 video card, which require minimum 450w power supply.
The power supply calculator shows that my current system without video card only uses about 200w power, which has about 165w power left unused.
