I have ProLiant ML110 G6
I've bought Sapphire Radeon R7 250 2GB GDDR5 card. Before I buy, I've checked compatibility of my PCIe v2 x16 slot with PCIe v3 x16 card. I'ts compatible backwards so I can use v3 card in my v2 slot i MB. But When I was trying to install it I've noticed that on MB is inprinted PCIe x16 45W (I attached photo below).
So can I use this card - in specification is given that consumption of this card is 70W. Can undervoltage break my G card?
Maybe I should ure Riser with extra molex pin? x16 slot gives 45W and molex can give 35W = total 80W. What you think

I have seen HP document PCI-E wattage below slot type specifications due to the installed power supply wattage size. The graphics card that you purchased has a recommended power supply size of 400 watts and your Proliant only has a 300 watt power supply. Your PC has significant age with an unknownconfiguation so it's had to tell if the 300 watt PSU will even come close to modern 300 watt power supplies. I noticed that the Sapphire Radeon R7 250 has a 75 watt rating.
Many years ago I had observed that a high powered PCI card actually melt the PCI slot. I don't think that will happen with modern PC technology.
Obviously HP has documented the PCI-e slot wattage rating for a reason.
