Should I be looking to replace this PSU soon?

post #1 of 7
Thread Starter 
I bought this PSU, http://www.silentpcreview.com/article936-page1.html, in the summer of 2009 it has gone through three complete system builds and has been working fine ever since. However this coming summer it will be 8 years old and I'm worried about its age. My initial components were energy (thus heat) guzzlers.

1st system: CPU: AMD Phenom X4 II 925 (OC'd), GPU: HD 4850 (OC'd), HDDs
2nd system: CPU: AMD FX-8320 (OC'd), GPU: HD 6870, HDDs
3rd system (current): CPU: i7-4790k, GPU: R9 290 XFX DD black edition (Gonna OC soon depending on the outcome of this thread), HDDs & SSDs

I want to upgrade my graphics card this summer with either a Vega part or a Pascal part(I don't really want to but if Vega is trash...), but I'm not sure if I should do that without changing my PSU. Granted these parts are going to be more efficient than what came before so I may be combating the loss in efficiency buy placing in more efficient parts over time.

Also, I use my computer a lot like at least 50-60 hours a week, less gaming over the years but the computer is always being used. I also turn off my computer every-time I am finished with it. If that data helps.

Thanks guys.

I actually went through the same thing myself recently, was sitting on a 8+ year old Seasonic 700W power supply.

IMO it would be a good idea to change your PSU. Capacitors have a finite life and they dry out over time which will cause increased ripple to your system leading to more wear and tear. This can cause instability or just reduce the life time of components.

Also newer power supplies are more efficient and will save you money in power consumption.

For your system a 650-750W PSU is more than enough. I run a system similar to yours on a 400W (4790k @ 4.5GHz with a GTX980).

I am a real fan of the new Seasonic Prime titanium PSUs. I have both the 650 and 750 versions of it. https://www.newegg.com/Product/Product.aspx?Item=N82E16817151158

Or if that is too expensive can drop down to platinum rated https://www.newegg.com/Product/Product.aspx?Item=N82E16817151172

Even 650 watt is overkill for a system with a single video card as the power draw is never much higher then 300-350 watts at most.

Yup I agree completely.

However these new Seasonics are very efficient even below 25-50% usage so you gain the longevity of running components cooler (higher speced components with better cooling) and able to run low speed fans or fans off entirely for silence.

650W also gives room to grow in the future if needed. I find PSU availability to be lacking in the 400-600W range. For example the Seasonic prime PSUs are offered as 650W being the lowest.

But yes nothing wrong with using a 500W PSU with a system like the OPs.

While the Seasonic Prime are very very good they are also very expensive
Ther EVGA SuperNova G3 is almost as good and cost less, the G3 also comes in a 550 watt version something the Prime lacks

If the OP is 100% sure he/she is never going to have two video cards a 550 watt is more then enough.

IMO its worth the extra $35 to go from gold to platinum given the longevity of PSUs. $130 is in the range of OPs PSU original price.

Can't say Titanium is worth it currently but $130 for 650W Platinum is a good deal to me.

$120 gets the 520W Platinum as well. https://www.newegg.com/Product/Product.aspx?Item=N82E16817151122

I'll probably settle for a 650w Platinum/Seasonic power supply for now I don't foresee me going multi-gpu in the future BUT there might be advances on that front in the coming years depending on how VR takes the market. But yeah 650w should be good for my current uses, when Vega comes out I'll make the final decision.

Thanks guys.
