Title: GTX 560Ti OC powered By ODIN Pro 550w
Post by: harry_levy on July 20, 2011, 11:31:43 am
Hi all,

I'm a new in this forum, and I love this brand.
I plan to replace my 9800GTX+ (GV-N98XPZL-1GH) with  the GTX560 Ti OC (GV-N560OC-1GI).
My questio id :  Is my ODin Pro 550W can support this card or i must change the PSU ?

My config : P35-DS3r, E6550, 6Gb of RAM, 2 HDD SATA, ODin Pro 550W, Windows 7 Integral X64 + WinXP (2nd boot)

Thank you.

Hi

To be honest as you have had the PSU for a while already it will have lost some of its output power anyway so it won't even be the full 550W that it was when installed. I would advise getting a larger one of around 650-750W now but of a similar quality not something cheap and nasty.

I would say if you have two pcie 6 pin connector on the PSU then you don't have to buy anything.
Your 550W PSU isnt giving the full 550W in any way , there is something called efficiency so if your PSU has a 80% efficiency it will give the Wattage considering this fact roughly around 500W.
A GTX 560Ti needs 170W to run under load, the OC version maybe a bit more, like 200 W max.
Even if your system is taking 200W (which i doubt) then your total consumption of your entire PC would be sitting around 400W +- 50W.
You still have a 50W headroom to go, so no need to buy new psu.
Try it with your current one, do a stress test , like occt or furmark and see if everything is okay.

I have a GTX480 SOC + and overclocked CPU Quad and I am running on a 650W PSU.
Perfectly stable except the fact that the GTX480 is running seriously hot!

You are quite right about the efficiency angle but that is assuming a new device. On an older component the time has taken it's toll on the internals mainly the large capacitors and you get what is referred to as capacitor droop. This means that the PSU is already less productive than it should be. If you then take the efficiency into account you have a rather reduced output. I think the OP would be better off replacing the PSU even if it is borderline as a safety measure. A failing PSU often takes a few other components with it and that can work out rather expensive.

While i agree with you on this, still a quality PSU like the 550W Odin is it shouldn't be a problem.
It should be a quality PSU and these do not take anything with them if they fail.
Usually you can just see system instability but its not going to blow like an atomic reactor and drag everything with it.
I agree chineese or noname PSU can blow up and take serious damage on system.

But as he stated he got a GIGABYTE ODIN 550W.
Even if we take in account the oldness of the PSU it should be more than enough to power the PC and the 560Ti since its not a real power hungry GPU.
Ive seen that thing running in a 4 years old PC with a 500W PSU without problems , but yeah this differs from PC to PC...and its more likely better to replace the PSU if its older than 2 years....

I agree it is a borderline decision and chances are the PSU would work fine for now but I just feel in the interests of safety and the fact that he wil probably have to replace it shortly anyway he might asd well do so now. Obviously it is his decision though. ;)
