Hi Guys, I'm looking for some advice on PSU's. When I use the online PSU calculators I get many different answers. I've convinced my wife that i'm using my income tax to upgrade my machine.... (ask the wife) Lmao!

My Upgrade --> ASUS Radeon R9 290 4GB Video Card
AMD FX Series FX-9370 8 Cores AM3+

My system now -->Windows 7 64-bit
-- AMD Phenom II X4 965 Black Edition
-- 16GB Dual-Channel DDR3 ram
-- Asus Sabertooth 990FX Motherboard
-- AMD Radeon HD 6850 Series GPU's - "Crossfired"
-- 500GB WD HD
-- DVD/CDrom
-- Corsair H100 cpu Liquid Cooled
--Thermaltake TR2 RX 750W PSU
--6 Case Fans

My question guys is.... is my 750w PSU good enough for my upgrade? I know the new Cpu and Gpu are beast on power but the Calculators online have results between 950W to 600W.

Tyvm in advance.

I would say that you should go buy a new 750w psu, the reason for that is that the TR2-RX is a poorly built psu. Check out this review, it doesn't even deliver the labeled wattage:
http://www.hardwaresecrets.com/article/Thermaltake-TR2-...
and it's in the "Replace immediately" category in this psu tier list:

I would get a XFX 750W XXX series psu, it's very high quality (actually "Tier one" in the psu tier list i linked) and more than enough to run your system (which probably would require a minimum of a 650w psu).
Here's a link to the psu:

EDIT: if you're wondering if the TR2-RX wouldn't be able to run at 650w, which i set as the minimum, then i can tell you, yes it probably will, and no don't make it even run 650w, the psu's ripple is too high at a decent load i would say. Ripple shortens your components lifespan.

Thank You Very Much for your answer NiCoM. I did not realize how bad my current PSU was... Damn. The links you have provided are awesome and will help me make my decision on a new PSU.

Thank You Again.



P.s. I do have a little question here unrelated... Probably a Noob question but... In my AMD Catalyst Control Center it says my Crossfire is enabled but when I open Piriform Speccy to check my system info it says my Crossfire is disabled and is only giving me one Temp. Hmmm..... ? Driver ??

idk, probably just a program error, check the fps for one card in a review and then check your own fps, if your fps is quite a bit higher then it's enabled and you shouldn't worry about what the program says.
