Will my LOW PSU Wattage cause my GPU to throttle and cause FPS drops?

I've made multiple threads here trying to figure out why i am getting FPS drops.
I noticed when the drops happen the power % on my video card drops to 50 then it the fps drops stop when it goes to 100%

I have a AMD FX-9370 220w,
A Gigabyte 970A-D3P
8gb DDR3
GTX 760 4gb

All on a RAIDMAX 630w
I know im low on wattage, could that be why?

I have a 575w PSU, i bridge the motherboard cable so i could use the dual 8pin adapters on the video card, so its ghetto with 2 psu and the case is off, but i still get FPS drops in all games that need lots of GPU to use it.

More about low psu wattage gpu throttle fps drops
  1. You are not on low wattage but the quality of your power supply is bad!
  2. then what is causing the throttling?

    I dont know rosewill that well being in the uk, but i can recommend Seasonic, antec, xfx& some corsairs(higher end versions) Rolli is right, not a great psu at all, 100% change especially with the amd 8core.

    For the throttling it 'might' be the mobo not being able to handle the watts or the heat(i think the mobo is about £50?) Not too many mobo's can handle that of a 8320/50(125w) let alone the 220tdp of the 9 series.

    Anyways, hope this helps.

    Your motherboard can not handle that CPU period only high end 990FX boards can https://docs.google.com/spreadsheet/pub?key=0AgN1D79Joo7tdE9xMUFlMEVWeFhuckJEVF9aMmtpUFE&chrome=false&gid=3
