hello i am wondering about power consumption. I have an older computer that i have, that i am suping up so i can use it in my shore house when i go down there. Today i picked up at gtx 550ti 1024mb! i am not looking to play huge games on it mainly just starcraft and minecraft. I know its not gonna max out everything so please don't troll with that. I am wondering if it really needs a 400 watt psu!??
will it be fine on like a 375 watt psu?
What would happen if its on a psu that doesn't put out that much wattage? will it just shut down? BSOD? or will it fry the gpu?
I am writting this at 4am so please don't troll my grammer etc.
If it is a good psu and not some low quality 375watt psu then it should be fine, but that depends on your other components too. The thing is that a cheap 375watt psu is likely not going to be able to put out a continous 375 watts of power, and that can lead to problems. If it cannot put out enough power then your pc may restart itself, you may see BSODs, and it can lock up and randomly freeze. Another thing to consider is that if the cheap psu is on a high load or overloaded then the voltages may fluctuate beyond the acceptable limits and that can cause problems with your components. A good psu is the heart of every system.
As others have said, give us the specs of your pc and the brand and model of your psu.
First off why do you have to put in your title "no noobs", Second why is the 3rd sentence in your question commenting about trolls? There’s is no need for that here. Comments like that actually attract the trolls.
To answer your question correctly we need to know the make and model of the PSU as well as what else is in the computer that will be drawing electricity. Perhaps the make and model of the PC, or at least the CPU.
GPU review list the 550ti at a max draw 116watts. If we assume you have a common core2duo your CPU and board only draw around 100watts that puts the total system draw around 220-250.
Here i9s a review of the PSU (http://www.hardwaresecrets.com/article/Dynex-400-W-Powe...). As you can see it was done in 2008 so this PSU is an older item in today's market. It is about about average or slightly below average in it's tested performance. Your 375w may be a better PSU depending on what it is. Read the review and make your own decisions unless you need more information from the forum. GL
