Hello, somewhat of a newb--Ultra 600w PSU cut out for me and wondering if I should go bigger--Intel dual core in a MSI mb, gtx 260graphics card. I did a calculator and it said that 450 was needed. but running monitor(FB game) and 2 the tv(hulu) I would get herky jerky pictures any suggestions would be appropriated
Also--recommend brands would be appreciated as welll--Never expected the Ultra to crap out on me
One of my systems has an OC'd Q9550, 4 GB RAM, a GTX260, a Gigabyte EP45-UD3P motherboard, 3 hard drives and an optical, and a Soundblaster card all powered by a Corsair 750TX.
Running 3 instances of Prime95 to load the CPU and 3DMark06 to load the GPU, it pulls 375 watts from the wall as measured by my Kill-a-Watt meter. Figuring 80% efficiency, the system pulls 300 watts from the PSU.
So a good 550 - 600 watt PSU will be more than adequate.
I would suggest using an Antec PSU. I have an Antec and I love it, its small, quiet, and powerful. For the wattage I would say anywhere form 600 to 800 (800 if you ever choose to upgrade things or overclock)
The Antec version seems more heavily built? Don't know if I am reading into this. If built by Seasonic I wonder what the real difference is between Antec version and Seasonic. The only think I notices was the Seasonic had a 5 year warenty vs Antecs 3 year.
^Some antec's are built by seasonic and loosely based on their designs, but use different components. For the lower end Antecs cheaper capacitors are used, some units only use 85C cheapo caps which wont last as long as the 105C japanese caps. read some reviews from hardwaresecrets and jonnyguru.
I just acquired a used silverstone 750w fully modular. Not a bad ps; a little noisy at startup, but quickly quiets down with the smartfan settings in the bios. It has 60 amps on the 12v rail, and the modular cables are very long. I got this one for $55 off craigslist.
Herky-jerky graphics aren't caused by PSU problems. Make sure you're using current drivers, and the latest version of Flash. Your graphics card should be powerful enough. What CPU? An old 805D might be struggling, whereas an e8400 or Core i3 should have no trouble at all. Check for background processes consuming CPU resources.
At this point the puter won't even boot up--while watching HULU and playing a FB game it just conked out. Both Hulu and the FB game were herky jerky--and if I went full size on the FB game the screen where I was watching HULU would lock, but the sound still played on.
I might be able to use a old power supply to check it--would have to pull the graphics card out due to not having the PCI-E plugs
