80+ Platinum rating, Great price, 3 Year warranty
Cons Non-modular


I Purchased this power supply to replace an 850 watt 80+ bronze PSU that was failing under heavy gaming load. As I am on a budget I wanted to find a PSU that would meet my needs and also be a reasonable price. This PSU with a 3 year warranty and an 80+ Platinum rating, for under $150.00 after tax (before rebate) seemed to fit the bill. I moved from a Modular to non-modular PSU but the install was not as bad as I expected. as the cables are well wrapped and organized. I ran my PC through some serious load testing to make sure that the issues I was having were indeed related to the old PSU. This Power supply is wonderful! I would recommend this to anyone who would like an efficient PSU at a proper price point. The warranty also proves to me as a consumer, that this product is designed to last and be reliable. Seriously consider this PSU before looking into anything with a higher power delivery with a lower 80+ rating.

Quiet, efficient, cheap, quality.
Cons None.


I've used this PSU for one year on my overclocked i5 4690K + Nvidia GTX560Ti with lots of peripherals and add-on cards. I draw about 300W at full load according to my UPS (with monitor and other hardware unplugged from UPS), and this PSU remains cool and quiet thgough it all, even after hours of load. I just ordered another one to shut up another machine.

For around a $100 bucks for a platinum rating you cant go wrong. Nothing fancy, but a good solid unit that runs quiet.
Cons None


Please note that the 4+4 Pin Connector is SHORT but this would not be a problem if your PSU was top mounted (in your case) as it doesn't have far to travel. However if you have a bottom mounted PSU get ready to get creative with your cabling.

As you can see, Platinum rating, which allows for better power bills.
Cons Not modular, so will requires so more cable management.


Great 650W PSU that will go with most mid range pc. Just try to get a nice case with it.

Cheapest 80+ Platinum with high quality parts throughout
Short (140mm depth)
Cons SATA/peripheral cables could be better designed
Not quite 80+ Platinum performance in NA 115VAC


For the Price, this is by far the best 80+ Gold/Platinum PSU you can buy.

It's silent and uses high quality parts throughout the unit, which is unlike some of the 'budget' gold/platinum PSUs other makers like corsair (cheap sleeve bearing fan) or rosewill (older PCB design and cheaper electronics) offer.

What makes this PSU particularly nice, is that it's very compact, which allows it to fit inside smaller cases, especially mITX cases, with ease.

The only downside is that this "Platinum" model really only scores Gold, which isn't a huge loss, by any means, and the SATA/peripheral cable daisychain could be better thought out.

For the SATA power connectors, it uses inline 90deg connectors with a sizable length of cord between connectors. This wouldn't be bad if SATA HDD spacing was actually that far apart, but they typically aren't and cause the cable to bend in a way that really ought to be avoided.
As for the peripheral (4-pin) power connectors, there are far too many for a PSU being sold today and could use one chain less of it for another SATA chain.

80PLUS Platinum
3 year warranty
Cons none so far for me


Bought it together with antec case working really well

Experience: 2 Months


Quiet under load
Cons None so far.


I have always used Antec PSUs and they never let me down. This PSU stays quiet even under heavy load and the temperatures are always low.

High current rails, silent and highly efficient.
Cons Non-modular.


In spite of being "only" 650w, the current on the rails of this PSU surpass that of higher power PSUs. Consider buying it rather than the others as you will both save money and energy thanks to the Platinum rating.

Le prix est bon, les cables de bonne longueurs, et plusieurs options de connecteurs.

80PLUS Platinum
3 year warranty
Cons Not modular


It powers my budget gaming system well. It has enough cable options. The length of cables is fine for an ATX motherboard.

It is hard to see from the pictures, but the fan grid bumps out of the PSU case. It wasn't too bad with my case, the air filter is pushed down due to the height difference. (Bottom mounted PSU with air filters underneath the case.)
