it will burn do not do it or your pc or maybe your house will be in fire
It's not recommended to use a 350 watt graphics card with a 300 watt power supply because the power supply may not be able to provide sufficient power for the graphics card's requirements. This can lead to system instability and potential damage to components. It's best to use a power supply that meets or exceeds the power requirements of the graphics card.
No. A power supply has to power all componets in a computer - processor, disk drives, optical storage, memory. So, a power supply has to be more powerful. Exact value depends on how much power all components use.
When purchasing a power supply, you need to consider the power output of the components you have (or plan to put inside) your PC. Your CPU, graphics card and hard drives will be the main power users, so get a power supply that matches the overall power output of your components. For example, my PC has an Intel i7 3770K and a GTX680 (overclocked) which are fairly higher-end components, and the 650 watt power supply powers those and my 2 hard-drives adequately. If you have a very new processor and graphics card (intel 4xxx series or geforce 7 series for example), then it would probably be good to go 700 or above.
It is not recommended to replace a 350 watt power supply with a 300 watt power supply, as the lower wattage may not provide enough power for your components. It's best to match or exceed the wattage of the original power supply to ensure proper functionality of your system.
Two PCI-E X16 Slots 500 watt or greater power supply
any power supply with at least 175 watts
A 350 watt power supply typically has multiple cables that connect to different components in a computer system. These cables typically include connectors for the motherboard, CPU, SATA drives, PCIe devices (such as graphics cards), and peripherals such as fans and lighting. Each cable leads to the corresponding component that requires power for proper operation.
Remove and replace the power supply.
The StarTech 250 Watt will work fine on any AMD computer, but it may not be able to handle a powerful video card.
It might be, but it will depend on what other things are in your computer. Remember that the power supply runs everything in the PC. And the more stuff you have in there, the higher the electrical load. In addition to the mother board, there are the hard drive(s), the CD and/or DVDs, etc. Got a TV interface? A fat sound card? More? You get the picture. Note that it can be a challenge to calculate loads in a machine like this, but know that the 550-watt supply is a good sized one. It should be noted that we're now seeing power supplies in the 600- and 700-watt range. And the supply is considered by some to be a weak link in the machine, as it is often overloaded. Take an inventory of your machine. What kind is it? What is in it? Then ask someone who actually has some technical knowledge (like a PC technician) to evaluate your setup and offer a suggestion.
I'll give you some hints of the things you have to do and I'll give you someone's email that works for a computer company who'll answer those questions or you can go to their website at tigerdirect.com. Well i want to get the same graphics card so i have info for you. Well first you need a good enough moniter. Which i think that monitor is good enough because i can tell by looking at the size so so far your good. Next you need a 400 watt power supply(by the way, the graphics card should come with a 6-pin connector to connect to your power supply and the power supply needs to be able to handle it). This is because the graphics card needs at least be connected to a 400 watt or more power supply. If you have that stuff so far so good. And by the way the 6-pin slot is in the back of the card, opposite the side where you connect your monitor into. That's all the info i can give you, but if you need more email Logan@tiger.tv or go onto tiger direct.com and they'll give you all the info you should need on it.
There is a 750 watt power supply and an 850 watt power supply. Both have gotten excellent customer ratings at various websites. I would check the specification compliance and voltage/frequency requirements that came with your device.
