520w Or 620w?

[somerandomguy12]

So I have a system that runs at 300w max according to PSU calculators and I have found 2 very good PSUs that cost the same.

 

1. Seasonic M12ii 520w 

2. Seasonic M12ii 620w 

 

Which should I get? the 520w which will drive my bills down or the 620w which will give me room for upgrades.

Also how much will my energy bill go down and it seems like GPUs and CPUs or consuing alot less power so maybe I would never even need close to 620w.

 

system:

Intel i5 4460

1TB Hard Drive

RX 480 ( if it lives up to the hype )

8GB RAM

 

What do you think!

Go with 620W. If your system truly takes 300W at its peak the difference in efficiency will be almost non existent.

How much will the bills go up by compared to the 520w?

1% at most

Okay, I will wait for a few more people opinions before closing this

I dont know your specs but if you calculator said it will take 300W that means it will take 300W AT MOST.

In normal usage it will take mabye 80W when browsing web and 200W when gaming.

 

PSU is most efficient at 50% load but since you will be runing at arond 10%-20% of load with both PSUs most of the time the efficiency will be almost the same and you simply wont be able to tell the difference on your power bill at all. The only thing that will affect is is how much time you will play games vs idling or just be on computer in general....

really people.. Where do you live if your power is so freaking expensive that you have count every single watt?

Honestly I would just go for the 520w. I am running a 4960k and a GTX 960 with a Corsair 430M no problem, you shouldn't have a problem either

If they cost the same, get the larger one.

 

PSUs are more efficient when running at lower wattage generally.

You can confirm this by checking the PSU's efficiency curve on the manufacture's website (or a third party benchmark if you don't trust the manufacture...)

As they cost the same then get the 620W.

[DXMember]

get the bigger one if they cost the same, you'll have somewhere to grow later with more powerful cards or maybe multiple cards

 

if you're into the efficiency you can get these tables, make some excel magic and calculate yourself

If they cost the same then there is no reason not to get the 620W. Why is this a question tbh?

[vagabond139]

You are going to save hardly any money, maybe a $1 a month, by getting a PSU that will run at peak efficiency during full load. Instead of the S12II units I would get a Corsair CX 450 watt PSU, just as good if not better and cheaper.

[RaspberryPiFan]

Go with a SeaSonic G series as those are very good units.http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story&reid=348

 

Pretty sure it is MOSFET based.
