Hey everyone! I'm doing a pc build with a MSI R5450-MD1GD3H/LP gpu. I'm having a little trouble finding the right power supply, and i believe i need a pci express connector to power the gpu. What pin setup do i need? All it says on newegg is that it is PCI Express 2.0 x16. Thanks in advance!
The Radeon 5450 doesn't consume enough power to require a PCI-E 6pin connector. The 5450 will work with a 250w power supply. As you can guess, the 5450 will struggle with games that are 3 years old. new games are almost unplayable with the 5450. It will do an ok job with an old game like Counterstrike Source. Pretty much every card that's under $90 doesn't require a 6-pin connector. You need at least a GTX 450 or a Radeon 6750 before you actually need a 6-pin connector. AMD is stark raving loony if they say the 5450 needs more than a 300w power supply. The card by it's self only uses 18w at the most.
What do you mean what pin setup? Im not sure you really know what you're asking for. The power supply needs to have enough power (wattage) to power all the components. Go for 450 or 500W at the minimum for a high powered gfx card. The PCI-e * 16 simply refers to the length and form factor of the PCI-e slot. Its very unlikely you have a computer which has a PCI-e slot but isn't a PCI-e 16 slot PCI-e * 8 slots are shorter, same for PCI-e * 4, with PCI-e * 1 slots being around an inch long.
Most PSU's come with either PCI-e x6 pin connectors, or PCI-e x 6 + 2 pin connectors. A 6 + 2 is basically the same as a 6, just with two extra pins, it will work just like a normal 6 pin however. Most graphics cards either need 1 or 2 of the PCI-e x6 pin power connectors to provide power. Make sure the PSU is at least 500+ watts (check the GPU's specs to see the specific power usage).
Usually a graphics card which requires its own power connections will come with adapter cables, or pci-e to molex adapters are easy to get
