I have a Dell Inspiron 530 with a ATX 300w Bestec (http://www.newpowersupply.com/bestec_300w_atx0300d5wb_atx_0300d5wb_rev_x3_dell_replacement_power_supply_part_number_xw601_xw600_xw599-pr-637.html). I'm thinking of buying a Radeon 5770 and the indicated requirements (http://www.amd.com/us/products/desktop/graphics/ati-radeon-hd-5000/hd-5770/Pages/ati-radeon-hd-5770-overview.aspx#3) show I need 450 watt's with a 75 watt 6 pin pci express power connector.
I have another card I considered first that I can afford but this is what I really want. I noticed that there are cheap psu's being sold for like 10-15 dollars. I know they wont last long, but I have to go the cheap route at this point. What is the cheapest 450 psu I can buy that has the connector required for the 5770 and all the rest of the connectors the Bestec has so I can power everything else. Forgive me if I sound kinda retarded as this is the first time I ever really explored anything about psu's.
One thing im afraid of... My mobo supports pcie1. Its my understanding that pcie 2 will run but 2.1 (like the 5770) is hit or miss. I read that someone is using a 2.1 card with the same model computer I have im going to take the risk. The thing is... I know the slot pcie 2 and 2.1 slots push more power than the pcie 1 slots. Im afraid that even if the mobo does accept the card.. that there wont be enough "combined" power from the slot its self and the power connector to run the card. Should I be concerned there?
Thanks you for your time. Sorry for the novel guys.
