New PSU drop in FPS

[DustinB]

Hello all new user here!

Just a quick question I just upgraded my PSU from a Dynex 520W to a Thermaltake 600W store bought from BestBuy. I will include my system details below but I installed this new PSU as I ordered a new GPU and it's in the mail but today when I installed the new PSU I actually noticed a DROP in FPS in one of the games I was playing (Napoleon Total War). Now before it was running smooth as silk and when I added the new PSU I changed no settings and the FPS took a drop and there is noticable lag in battles and throughout the game. Any ideas?

System Specs:
CPU: AMD Phenom IIx4 965 (Deneb) @ 3.4
GPU: Nvidia GTX 550 Ti
PSU: Thermaltake TR2 600W
MOBO: CG1330 ASUS (Stock)
Thanks!

did you plug everything in where it needed to be? like the cpu power, pci-e power? i know it sounds basic, and i don't mean to insult you, but just forgetting to do one power connection to your board or vid card could cause this.

AFAIK a PS should not cause this type of issue. Easy fix, put the old one back in...

Do you have any before/after numbers? If you were right on the edge (of smoothness) in the first place, it wouldn't take much to make it seem like it's struggling.

No I have no before/after numbers, I think I'm going to put my old Dynex back in and see what happens. I know that 520W PSU should suffice for my new GTX 660Ti card but I just wanted to be on the safe side because I do have a chassis fan running too but it shouldn't be much of a problem. Will double check my connections and if need be replace old PSU, I'll check back in. Thanks guys.

520 should be plenty for you new card.

Just swapped the Dynex 520 back in and so far I think my problem has been solved. Using the same settings on Napoleon the battles run about as smooth as they did before. I understand that I shouldn't skimp when it comes to buying PSUs but Dynex isn't exactly top of the line either and it's pretty sad that a brand new Thermaltake 600 performs like this. Thanks again guys.
