Psu for 750ti

[Fu11meta1]

Specs -
I3 3220
4gb x2 corsair vengeance ram
Zotac 750 ti 2gb gpu
Gigabyte h61m-hd2 mobo


My old CM thunder 450w failed with these specs after 2 weeks.
Why?

Also suggest me some good PSUs enough for these specs

It failed because of its poor capacitors and build quality, not due to your power requirements. It would likely happen regardless of your hardware upgrade. A quality 300W PSU can power the 750Ti without issues, but it is better to have more for additional headroom.

Get this one, excellent quality (made by Seasonic) and you can use any graphics card you want (as long it is not a dual gpu):

XFX PSUs are not available in my country.
Recommend a corsair, seasonic, antec or CM only

This tool http://www.extreme.outervision.com/psucalculatorlite.jsp will give you a good idea of how many watts you need.

I would choose a trusted brand like seasonic, corsair or antec.

Any Seasonic you can find will do, they are all excellent in quality. Look at 500-550W range to be more future-proof.

As for Antec, they are great as well, especially their High Current Gamer series. Neo Eco is also OK, as is TruePower Classic.

I would not take anything from Corsair, overpriced for the quality you get.

Which psu is good? I don't want another cm thunder

I feel your pain, mate. At least now you know why cheap PSUs should be avoided at all costs. And you got lucky if nothing else got burned in the process. Take any of those and you are golden:

Whats your budget ??

Low budget http://www.amazon.com/Corsair-Builder-Series-Watt-CX500/dp/B0092ML0MY

High Budget http://www.amazon.com/Corsair-450-Watt-80PLUS-Gold-Certified-CP-9020066-NA/dp/B00EB7ULNO/ref=sr_1_1?s=electronics&ie=UTF8&qid=1431607515&sr=1-1&keywords=corsair+psu+450

All depends on what you need and want.

Seasonic S12II 430w is good? For my system?

 

[herrwizo]

Perfectly fine, mate. The only reason I recommended 520-550W is to be future-proof. For instance, if you one day decide to get a much stronger card, you will have to upgrade the PSU again. And there is no reason to, since a 520W unit is only slightly more expensive than 430W.

One more question.
What is the life span of an average psu?
Like this seasonic S12II 430w?
My cm thunder 450w failed in only 2 years

 

[herrwizo]

Most quality PSUs have warranty of at least 5 years (like this Seasonic). There are even PSUs with 10 years of warranty (EVGA B2 750W, for example). Cheap ones have up to 2 years warranty, and you can consider yourself lucky if they last even that long in most (not all) cases.
