Two PSUs are better than one

[H]ard|OCP visits the weird world of dual PSU products, which allow the usage of two PSUs in a single system and which are transparent to the end user as they are both controlled as if there was only one.  There are four methods covered; Add2Psu, the Lian Li Secondary Power Supply Starter Kit and both auxiliary and redundant PSUs.  They range in style from the impressive abilities of Add2Psu to string together unlimited amounts of PSU using Molex connectors and Lian Li's PSU crossover cable to FSP's 5.25" Booster X5 450W auxiliary PSU and the Athena Atlas 800 redundant PSU which seems more at home in the server room. If you want more power but don't have a PSU big enough this will show you how to give your existing PSU a helping hand.

"Putting two powers supplies in your computer has been a recurring subject in our forums for years. While the physical process of making that happen is not exactly rocket science, it still can be daunting for some users. Today we show you a few products that make it easy for anyone to double up on the power should your wattage needs increase."

Power up with 1350W of Silver ToughPower

Subject: Cases and Cooling | August 16, 2011 - 03:33 PM |
Tagged: PSU, thermaltake, Toughpower 1350W, modular psu

The 80+ Silver rating on the Thermaltake Toughpower 1350W is well deserved according to the tests that [H]ard|OCP ran, something which can add up over a year of load.  The six 8 pin PCI-Express connectors are on one 12v rail, capable of up to 750W @ 60A, while the other 12v rail handles the other connectors.  Those other connectors include twelve SATA and eight Molex connectors, which should handle most configurations with cordage to spare.  It does very well on the most important function of providing decent quality power even in harsh conditions, but does cost a bit more than some competing PSUs which you should bear in mind before picking up this PSU.

"Thermaltake is back on our test benches and back with some very big iron. Thermaltake made some of the "biggest and baddest" computer power supplies years ago and we are about to find out if the company does once again. However this Toughpower is well above a kilowatt and surely will have a limited appeal, but also surely attract a lot of attention."

In Win's entrance to the Kilowatt Club

Subject: Cases and Cooling | August 8, 2011 - 02:34 PM |
Tagged: PSU, kilowatt, in win, Commander II 1200W

Just a few short years ago on the PC Perspective Podcast you could have heard us crack jokes about people need a kilowatt PSU plugged into 240V mains in order to run their high end PCs.  It seems that the joke was on us as most major PSU vendors have at least one model that provides 1kW+ of power, thankfully most also do it more efficiently than older generation PSUs and do not need a 240V plug.  In Win has joined the ranks of the high powered PSU makers with their new Commander II 1200W Modular PSU.  The 80+ Bronze rating is a good sign and the silent 135mm fan is also a good touch, but the two most important features are the solidity of the power it provides and the price it is available at.  Find out about those in ThinkComputers' latest PSU review.

"In Win, the company that brought you many different types of cases in the past is now upgrading one of its power supply series into the 80PLUS age. The Commander II series of power supplies, the successor to the original Commander, are available in three different models: 750W, 850W and the 1200W, which we have to review today. All three models are 80PLUS Bronze certified, have an army green color scheme and a silent 135mm fan in them."

Thermaltake's new semi-modular kilowatt class ToughPower PSU

Tagged: PSU, thermaltake, ToughPower Grand 1200W, kilowatt

Thermaltake has a new top of the line PSU out, the ToughPower Grand 1200W Modular 80+ Gold PSU.  As you can see below, all but the motherboard connectors are modular, which is not going to be a problem for anyone with a cable management fetish.  There are eight 6+2 PCIe connectors for multi-GPU users and a dozen SATA connectors for the storage guru, with dual +12V rails which are 40 amp and 80 amp respectively.  Bjorn3D's testing revealed a few flaws which hurt their opinion of the PSU, especially when they factored in the high price of this unit.  The biggest flaw was the PSU's vulnerability to shorting out if long screws were used to mount it.

"Today, we will be taking a look at Thermaltake's flagship 80Plus Gold Certified ToughPower Grand 1200W Modular Power Supply. While this power supply is designed for overclockers and gamers that use multi-GPU setups, it is not 100% modular. This usually is not a problem with users that run high-end gaming hardware, but it might be a bit frustrating for those that just want to have a powerful PSU for the future but might not be running high-end hardware at first. For instance, its double 8-pin CPU power connector is hard wired into the power supply. Only a very limited number of motherboards support dual 8-pin power connectors, and this type of setup is only necessary for extreme overclockers for extra stability."

1300 watts of golden power from Enermax

Subject: Cases and Cooling | July 22, 2011 - 03:07 PM |
Tagged: enermax, kilowatt, 80+ gold, MAXREVO 1350W, PSU

The Enermax MAXREVO 1350W PSU missed getting an 80+ Platinum rating by 1%, which puts it in rare company, kilowatt class or not.  Not only that, but in RealWorldLabs' testing it produced under 40dB under load which is impressively quiet for a 1350W PSU.  With 112 amps available to the six 12V rails and eight PCI-Express connectors ensure support for whatever multi-GPU monster you envision building.  All of that quality and those features do mean a higher price, $300 is the entry fee for this PSU.  It is worth it if you need it.

"The latest MAXREVO 1350W 80Plus Gold certified power supply unit by Enermax is not only a worthy successor to their already excellent Revolution85+ series but also one of the two most powerful all-modular units in the market with support for future power connectors, right next to its 1500W brother."

The Scythe Chouriki 2 Plug-In 850 W isn't worth a 2nd glance

Subject: Cases and Cooling | July 7, 2011 - 06:22 PM |
Tagged: PSU, modular psu, scythe, chouriki 2

Starting out with the positive, the Scythe Chouriki 2 Plug-In 850W can keep it's efficiency well above 80% in most usage scenarios.  Unfortunately that is about the only positive impressions that techPowerUp walked away with after wrapping up their reveiw.  The +12V line displayed dismaying amounts of ripple and the +3.3V rail actually strayed outside the 5% limit when stressed.  Finally, at a hair under $180 the Scythe Chouriki 2 Plug-In 850W is not even reasonably priced for an 850W PSU.

"Most of you will probably know Scythe from its cooling products, but the company also has several power supplies in its arsenal. Today we will test the second strongest PSU from the Chouriki 2 Plug-In line, which has 850 W capacity and is 80 Plus Silver rated. All Chouriki 2 Plug-In PSUs use a semi-modular cabling design and are backed up by a five-year warranty."

A new and improved high powered Professional Series PSU from Corsair

Subject: Cases and Cooling | June 28, 2011 - 11:56 AM |
Tagged: PSU, hx1050, corsair, 80+ silver

The original Corsair Professional Series HX1000W was well received when it arrived, Lee handed it a Gold Award at the end of his review.  They have updated their HX lineup with the new HX1050 which keeps the original design and components but adds a few more watts to the peak power rating. The single 12V rail can provide 87.5A and with six 6+2 pin PCIe power connectors, this PSU was designed with the extreme enthusiast in mind.  TechPowerUp put the HX1050 through their test suite, seeing solid power provided throughout the testing and efficiency at or above the 80 Plus rating that Corsair advertises. At $230 this is a fairly expensive PSU but if you need this amount of power you could do worse than the Corsair Professional Series HX1050.

TPU_corsair_hx1050.jpg

"At Computex 2011 Corsair revealed a new model for the Professional HX series, the HX1050 which will replace the successful HX1000. The OEM remained the same, Channel Well Technology, the capacity increased by 50 W and efficiency remained at 80 Plus Silver. It seems like this PSU has what it takes to be a cost-effective alternative to the Corsair AX1200."
