Do I really need an 80+ Gold? Or would a bronze suffice.

I heard Superflower is a good maker. Is that true?

What PSU are you thinking about getting? It's not just the 80+ rating but the stability and amperage of the rails that you need to be concerned about. However, when buying a gold PSU or even a bronze from a reputable brand you can be sure that there wouldn't be a problem anyway.

Very. Superflower is an OEM up there with the likes of Seasonic and Channel Well Technologies. Their units are rock solid.

bronze is fine, don't worry about it. Just make sure you get the PSU from a reputable brand with good reviews.

The GS650 is an excellent PSU, but if you don't need full modular and you can live with semi, the 750B2 is a better deal, you get 100 more watts and save 15 bucks. http://pcpartpicker.com/part/evga-power-supply-110b20750vr

 

As stated earlier you won't notice the difference between bronze and gold anyways, both the GS and B2 are solid units.

The main difference between Gold and Bronze is it's efficiency to convert AC to DC current as PC components cannot utilize AC power with out burning up.

 

Check out Linus's video on PSU ratings.

The rating are based on the following efficiency;

Bronze: 85-86%  

Silver: 88-89% 

Gold: 91-92%

Platinum: 93-94% 

All ratings are based on the load put on the PSU, peak efficiency is common at 48-68% load (this will vary by Brand, Model and Rating. Most PSU Makers will post a graph showing it efficiency curve for each of its PSU's. I won't buy a PSU if a graph is not available, that's just me. See the images for an example.

Each level of efficiency can affect your power bill over time as the lower the efficiency the higher the amount of electricity is used to convert from AC to DC.A reputable maker is Always the way to go as low end PSU's (even supposedly rated at Gold standard) can kill a board more times than not. Do Not Cheap Out on your PSU. A good reputable PSU maker will inherently add a number of filters to reduce (smooth) the frequency of the current passing through, as well built-in surge protectors. A bad PSU can destroy your $500-$3000 machine real fast. The higher the rating will also have available better, longer lasting parts.

 

One other thing to keep in mind in getting a PSU that is get one rated for more wattage than you need will perform better over time is your load will be lower, less heat will be generated and your efficiency is increased. A PSU with a full or nearly full load will burn up quicker, generate immense heat and be more prone to failure at the moment your in the middle of something important (always happens that way). 

 

A Bronze will work out well but if your into saving your power bill, a gold will work out better especially if your system pulls a lot of wattage.

Honestly it your your choice really. Pay higher up front price and save over time, pay cheap and lose your system to a sub-par PSU OR pay a relative decent price and pay mid to higher electric bill.

I suggest you do the math and for your areas electric prices to see if the life of your PSU chose will gain anything versus your electrical usage and bill.

 

Hope that helps :D

CWT isn't that reputable for PSUs that people would refer to as "rock solid"

The Whos who list of PSU makers.

http://www.tomshardware.com/reviews/power-supply-psu-brands,3762-5.html

 

Gives a comprehensive list of what brands there are, who makes what and who are the re-branders.

 

Hope that helps as well. You will be surprised at what you see here.

Efficiency doesn't really matter unless electricity costs are a big deal.

That list is quite outdated and doesn't feature many newer PSUs that you'll find on the market and suggested on the forum today. You can always ask here for what PSU is good though :P

Efficiency = Electrical cost. A bigger bill is a bigger bill. If your not worried about cost then your point is valid. Your statement is however not valid as I was answering the question asked. (not trying to be argumentative here)

 

Higher the efficiency, lower the amount of electricity used = lower electric bill. Lower the efficiency, higher the amount of electricity used = higher electric bill. 

Cost of the PSU (higher or lower) + your load or usage x the amount you pay per Kw. This is good formula to determine a decent figure on how much to pay for a PSU.

Doesn't matter how old the article is (besides it not that old) hasn't changed much in terms who builds what for who. The list is still valid mostly Toms hardware is always updating the list.

I never said it was a bad resource, it's just that not everything is there including many of the newer good suggestions on this forum. Heck it doesn't even have the EVGA G2 (or B2 or GS). It's a good starting resource, but still not as good as just asking here regarding a particular PSU model.

Right on.

Sorry, it wasn't meant to be argumentative. I had a moment there elsewhere and my reply showed some spill over.
