Corsair TX750W replacement ?

[bru]

I've Got a Corsair TX750W and the fan in it has started making a load of noise. After taking it apart I see that it all looks to be in good order but the fan has obviously seen better days, the bearing makes a perceptible grinding noise when turned by hand, so I'm not surprised it makes a racket when powered. It is probable not long for this world before it stops altogether.

So the question is do I just replace the fan, which is easy to do and I assume that due to the currant fan just being two wires it will not just run a new fan flat out all the time but the PSU itself modulates the voltage for speed control.

Or do I bite the bullet and replace the 6 year old unit (yes I checked, bought it from here 10th dec 08 for a whole £69.99 )

I was looking at the following possible replacements.

YOUR BASKET
1 x EVGA SuperNova G2 1000W '80 Plus Gold' Modular Power Supply £119.99
1 x EVGA SuperNova G1 1000W '80 Plus Gold' Modular Power Supply £109.99
1 x Corsair CS850M 850W Semi-Modular 80+ GOLD Certified Power Supply (CP-9020086-UK) £99.95
1 x EVGA SuperNova G2 750W '80 Plus Gold' Modular Power Supply £79.99
Total : £409.92 (includes shipping : ).



Yes I know there is no superflower in there, but then again aren't the EVGA's the same minus the LED's ?

Currant PC spec, x58a with i7 920@4GHz ( just about to be replaced with a xeon 5650 which will be clocked as high as it will go), single 970 ( quite possibly to be doubled up on soon) 6 HDD, SSD, dvd, fan controller, watercooling pump (D5) and 5*120mm fans, 2*230mm fans.

I know I probably don't need that big a PSU, but then we don't all need 5GHz CPU, multi GPU, 16GB+ ram, huge monitor....etc..etc..etc but we want it

So nobody suggesting just replace the fan for under a tenner ?

Not on a 6 year old psu. It's had a good run and now would be a good time to replace it. At the end of the day it's up to you.

I had 4.5y old TX650 die on me (luckily 5y warranty and didn't damage other parts), so no, I would not recommend a fan replacement.

Fair enough, a replacement it is then.

Ok So it definitely going to be a replacement, but the question now remains which one?

The EVGA 750w G2 is the obvious choice as it is a direct replacement for the outgoing TX750.
But back when I bought the Corsair TX750, I was thinking about being as future proof as possible. then I was running a [email protected] and a GTX260, which seems like so long ago now.

q6600 105tdp GTX260 182tdp

xeon 5650 95tdp GTX970 145tdp

Obviously everything is overclocked but things haven't really changed that much (even though the Maxwell's are showing some impressive savings over the previous kepler GPU's) I nearly went for SLI 670's but I'm not sure that the 750w would have been comfortable enough with the i7 920@4GHz with SLI 670's and everything else.
So with that being said is 750 going to be enough for the next 6 years
or is it worth spending the extra £30 now for the 1000w G1 or extra £40 ( which I suppose is 50% more) for the 1000w G2 just for the 10 year warranty?

My currant power usage while running prime and heaven together.

So a new 750w PSU could do SLI 970's but could it do SLI big Maxwell's or even Xfire 390x's or who knows what in the future.

Don't want to have to buy another until it needs replacing, but then it is another 50% more.......

Comments please.

I just checked some SLI GTX980 reviews and these cards are ridiculously power efficient. Most reviews have total system load at around 450w. For total load with a pair of cards that's extremely low. I can make my pc pull more than that and the gpu isn't even clocked!! With that in mind the 750w G2 would still be more than enough. Not sure about 390X or whatever AMD's next cards are going to be. If I was running a pair of 290X cards now I would want 850w as they are so power hungry. If you are sticking with Nvidia and are still not convinced and want the 1000w for the extra (unneccessary) headroom then yes, I would pay the extra for the G2 unit with the 10 year warranty.

So in one breath you say 750w is enough, then another that you would want 850w, yet another that 1000w is unnecessary.

Still not sure what's best, probably the 750w but I just know I will be kicking myself if in a year or so it turns out to be not enough.

Ok cheers, that makes more sense now.
I think I'm just being a bit paranoid, 750 has been fine for the last 6 years, so I'm sure it would be fine for the next good few.

Grrrrr..... I shouldn't of dithered, the 750 G2'2 are out of stock now. .....Grrrrr
