If you want it to last 4 years, you should get a five year warranty. You will have to pay for that.
Look, I've said it at least 100 times; DON't skimp on the power supply!! You will find other places to save money on your build but don't try to save on the power!!

You want to crossifre with a cheap PSU??

I do not intend to skimp on my power supply. I just don't want anything overkill.

I never said I wished to purchase a "cheap" power supply, I said I wanted the "cheapest" for my needs.

Where do you suggest I can save money elsewhere on my build?

The SeaSonic G Series SSR-550RM 550W will be more than enough for your AMD 7870 and Intel i5-3570K.
Stable voltages, 5 year warranty, 80 plus gold efficiency (you will earn back money and more in 4 years on electric bills compared to bronze efficiency) for a price of $79.99 +$10.18 S/H.

Ok so what we know is you want enough headroom to possibly run crossfire/sli. To accomplish that and still leave yourself enough headroom for a possible overclock and to make sure your PSU is not over worked You will likely want something around 700-850watts.

Is that the cheapest tier 1?

Also, what makes certain power supplies better than others? The 80+ rating? There are 80+ Golds on Newegg for the same price as the one the guy I'm quoting recommended, which is 80+ Silver....

I'm confused.

I was also told to stay away from carsair which would have been my choice of brands as they have recently changed there suppliers.

corsair doesn't change their suppliers, they have more than 1 provider depending on the specific unit. Most psu brands done even generate the base model for their psus, which they contract another oem to base a model, and make follow up modifications to the said unit. You just have to know which specific unit is good, and which is not. Realhardtechx has a pretty updated list of reviews for several units from several brands which is good to look through, as it tells you information on rail wattage, the original OEM and such.

Thanks for the website plenty of info.

the corsair model I was looking at was the tx850 which used to be made by seasonic but now made by ctw which don`t seem to have such good reviews

At this point, I'm mightily confused, so I decided to look at some other i5-3570k/Radeon 7870 builds to see what they recommended. My questions now are:

How much wattage do I need? (Remember I want to crossfire and overclock at some point)

Which 80+ rating has best price-performance? My guess is 80+ Silver.

If I were to find three PSUs, one 80+ Bronze, one silver, and one gold at the same price (theoretically) with enough wattage, would the 80+ gold one always be better?

Thanks, and Merry Christmas.

It's seasonic oem, tier 1 quality psu, 750w plus silver modular(enough juice for two 7870 or 7950 oc+whatever cpu+couple of fans+hdds,ssds,etc).
And it's the cheapest you'll find.

The rating gold/silver/bronze just is a benchmark to show how efficient the PSU is. All it measures is how much power the PSU outputs at different input levels. It has nothing to do with the quality. Quality is determined by design, components used, build quality and warranty. It may or may not be the cheapest tier one depending on sales. It just seemed to be a good buy on the site I looked at.

The list was updated in November 2012. So it is fairly current. However they do not remove old PSU units that were discontinued because occasionally you can still locate and oldie but goodie. For instance during the black Friday sale I was able to pick up an Antec TruePower Quattro 1200w unit for 99$ off of new egg. The unit has been discontinued so new egg was unloading their stock for less than 50% of retail.

A good PSU is a factor of the components it is made from, the design, quality manufacturing, and the warranty the company places on its products. As certain units are produced by a 3rd party supplier and rebranded or produced in multiple factories it is possible for one model of a PSU to be fantastic and others from the same company to suck. That is why the list I linked contains so many side notes.

As to your question about wattage I stand behind what I said before.

"Ok so what we know is you want enough headroom to possibly run crossfire/sli. To accomplish that and still leave yourself enough headroom for a possible overclock and to make sure your PSU is not over worked You will likely want something around 700-850watts."

Unless you plan on running SLI/Xfire with overclocked flagship models IE (7970 etc) wattage in this range should be perfect for you.

In regards to your question about Bronze/Silver/Gold rated PSUs all it refers to is how efficient the PSU is with the power it draws. For example for a gold rated 800w PSU to generate 800w of power for a computer it would need to draw 904w or less. By comparison a silver rated PSU would draw between 905-920w and a bronze rated PSU would require 921-944w. The simplest way to think about it is a gold rated PSU will lower your power bill a bit.

When I got my Vista laptop a Windows 7 Home Premium 32 bit upgrade came along with it, which I will use with this system temporarily until my needs require more RAM and Windows 8 becomes more stable.

Back to PSUs....

You know how there's a price-performance sweetspot in GPUs and CPUs, like the 3570k and the 7870? Where's the spot in PSUs? Ultimately, that will determine my decision.

I also need to figure this out pretty soon, as to take advantage of some deals I have to order a few parts tomorrow.

I made a couple of suggestions best psus for the buck for 7870 or 7950 crossfire :

http://www.newegg.com/Product/Product.aspx?Item=N82E168...


They're all top quality psus, all of them modular ones, and at the best price possible, but there's also a cheaper one with quality but not modular : http://us.ncix.com/products/?sku=59909&vpn=CMPSU-700G&m...
Also consider checking the prices of 660ti, it has a great value price/performance, also consider the upgrade right now for a os 64 bits, 8GB ram is really cheap nowadays.

Yes, it's also good for 7870 crossfire, it's not modular and not has good as the others mentioned, but it's a quality psu and it can power your system with two 7870.

Great, the Antec one I picked just went back up to $120.

Honestly, the XFX looks good. BUT, what's the best out there for $70? Is the XFX 750W XXX Edition the best value at the price (of $80)

I really wanted to keep it at $70.

The keys are interchangeable between 32 and 64 bit versions. Just install the 64 bit version and use your key.


If your serious about keeping your PSU expenditure at $70, then your best option is the Corsair CX750. As of this writing, its $69 with a $20 rebate added on that could make it $49. But realize your compromising somewhat at that price point. That said, you would likely be happy with it.

http://us.ncix.com/products/?sku=75728&vpn=CP-9020015-N...


If your willing to shell out a few extra pesos for the quality level stated in your original goals, there are a fair number of good choices that are only a few dollars more. Were I in your position, these would be my finalists:

SeaSonic X Series X650 Gold

http://www.newegg.com/Product/Product.aspx?Item=N82E168...



Corsair HX650

http://us.ncix.com/products/?sku=42532&promoid=1226


Both are listed at $89 as of this writing. The X-650 is a somewhat better unit in that it has slightly better regulation and efficiency. The corsair has a 7 year warranty to the Seasonic 5 year. Both are built so well, they will likely outlive some of us.

That's my 2 cents.

That is Canadian dollars, people here are underestimating the corsair GS 700w, but it's the best one for now at less than or no more than 70$ :

http://us.ncix.com/products/?sku=59909&vpn=CMPSU-700G&m...

I put right in the first post, and it still stands as a good option, it can do for two 7870, 7950 or 660/660ti, it's not modular, but it's a good quality psu and will offer more than he needs.

I'll think I'll go with the http://us.ncix.com/products/?sku=75728&vpn=CP-9020015-N... you recommended. Power supplies don't affect performance, so as long as I get one quality and for good money I'm happy.

The CX I'm looking at is Bronze certified, while the GS equivalent is not medal-certified, which is lower. They have similar quality and reviews and the CX is $50 after rebate, so to me, the CX is better. Any objections? I'm buying my system tonight.
