Enermax NAXN 80+ 600 W Power Supply

Enermax NAXN 80+ 600 W Power Supply

The NAXN, the latest power supply series from Enermax, is subdivided into three sub-series: the NAXN, also known as Tomahawk II, featuring 350 W, 450 W, and 500 W models, with no 80 Plus certification; the NAXN 80+, featuring 350 W, 450 W, 500 W, and 600 W models, with the standard 80 Plus certification; and the NAXN 82+, featuring 750 W and 850 W models, with the 80 Plus Bronze certification and modular cabling system (a feature not available on the models from the other two sub-series.) Let's see if the new Enermax NAXN 80+ 600 W is a good option.

Thermaltake Toughpower Grand 1200W Power Supply

Thermaltake Toughpower Grand 1200W Power Supply

The Grand is a dual 12v rail unit that has an unprecedented 125A between the two of them. Meeting the requirement for having an 80PLUS Gold rating, the unit promises to be a winner when it comes to stability and the reliability which is ever present in Thermaltake products. Speaking of quality, Thermaltake is so confident in the Grand series that they are offering a very impressive 7 year warranty on them. Join us as we take a look at this behemoth of a power supply and see if it is worthy of your time and hard earned (or saved) money.

Cougar CMX 550w

Cougar CMX 550w

Since Hardware Secrets made us all look a little silly a few years ago, without access to the full test setups that the big sites and PSU manufacturers have, XSR has backed off its PSU reviews to instead make them unboxing-previews. Please bare in mind that this preview of the Cougar CMX 550w will not include any performance numbers.

Nesteq ASM Xzero 600W Semi-Fanless Power Supply Unit

Nesteq ASM Xzero 600W Semi-Fanless Power Supply Unit

Compared with companies such as Corsair and Enermax, NesteQ is a relatively small company when it comes to PSUs. When I told a few of my friends about this PSU, the majority of them had never even heard on NesteQ. However, for those of us who have been following PC hardware for a while will know that NesteQ is famed for their quiet PSUs and other products aimed at reducing noise from your system. This new PSU is no exception.

Modern PSUs are generally made from the same mould; a large fan on the bottom, a grill at the back, a power switch and the necessary internals. Although one manufacturer will sometimes bring new aesthetic designs to the table the general functionality of a PSU remains fairly standard. However, NesteQ have set these guidelines aside and have crafted a truly unique product.

In this review we will be taking a look at Nesteq's Xzero PSU and what it can offer in comparison to the vast majority of power supplies on the market. And most importantly, are these new features genuinely useful or just gimmicks to raise the price? We shall be finding out about that and more later on.

Corsair TX850 V2 Power Supply

Corsair TX850 V2 Power Supply

Let's take a look at the revamped Corsair TX850 power supply, dubbed TX850 V2, now featuring a DC-DC design and 80 Plus Bronze certification. It is important to understand that while the old TX850 was manufactured by CWT, being a relabeled 850VH unit from this manufacturer, the new Corsair TX850 V2 is manufactured by Seasonic, being internally identical to the XFX PRO 850 W unit.

Logisys PS350MA Power Supply

Logisys PS350MA Power Supply

The Logisys PS350MA, targeted to small form factor (SFF) computers, measures only 4.9 x 2.5 x 3.9 inches (125 x 63.5 x 100 mm) (W x H x D). This unit raises several red flags as being a really bad product. First, it uses the SFX12V form factor, but the manufacturer is not aware of that, calling it a "Micro ATX" power supply. Second, it is sold as being a 350 W unit; however, the power supply label says that 350 W is the peak wattage, and the "average output" is 250 W. And, third, the label and product specification found online says the product only works at 220 V/50 Hz, but the unit clearly has a 110 V/220 V switch. Let's see if our suspicions hold true or if this unit will surprise us.

Sentey Golden Steel Power 850 W Power Supply

Sentey Golden Steel Power 850 W Power Supply

The Golden Steel Power is an 80 Plus Gold power supply series from Sentey, featuring a modular cabling system, resonant switching, synchronous rectification, and DC-DC design, coming with a terrific price tag for the features offered. Let's see if the 850 W model is a good option.

SilverStone Strider Gold 750W

SilverStone Strider Gold 750W

Most often when mentioning SilverStone at Phoronix, it is about one of their phenomenally designed cases like the Temjin TJ10, Fortress FT02, or most recently the Fortress FT03. Enclosures and other peripherals aren't our primary focus at Phoronix for being a Linux-focused hardware outfit, but it's always interesting seeing as what SilverStone comes up with in their new designs. Even though their products have been reviewed at Phoronix for the past six years, their new products always manage to push the envelope further. When it's not a SilverStone enclosure, it's usually a power supply, and that's what we're looking at today; up on the review block is a SilverStone Strider Gold 750W.

Corsair CX430 V2 Power Supply

Corsair CX430 V2 Power Supply

We were really surprised by the original Corsair CX430, a unit that doesn't have the 80 Plus certification but is able to present a terrific performance for its price point. Corsair updated the CX430 to include the standard 80 Plus certification and to extend its warranty from two to three years. The good news is that the new CX430 V2 is available at exactly the same price as the original CX430. Let's see how the new CX430 V2 stacks up against the original CX430.

LEPA G700-MA Power Supply

LEPA G700-MA Power Supply

LEPA is a newcomer to the power supply market, established by Ecomaster, the official distributor of Enermax power supplies in the United States. The LEPA G series is the Enermax MODU87+ series with a different name, and we don't understand why the same distributor offers the same power supplies under two different brands. We've already reviewed the LEPA G500-MA and the Enermax MODU87+ 700 W, and both proved to be excellent products. Let's see if the LEPA G700-MA is also a good option.

Athena Power AP-MFATX35 350 W Power Supply

Athena Power AP-MFATX35 350 W Power Supply

The Athena Power AP-MFATX35 measures only 3.2" x 1.7" x 6" (80 x 40 x 150 mm) (W x H x D), being targeted to small form factor (SFF) computers with Mini-ITX motherboards. Rated at 350 W, is has the 80 Plus Bronze certification, which promises at least 82% efficiency. Let's see if this product is a good option.

OCZ ZX Series 850W Modular Power Supply

OCZ ZX Series 850W Modular Power Supply

OCZ has recently released its latest power supply offering in the ZX Series of power supplies.  These power supplies effectively replace the Z Series power supplies in the Maximum Performance sector and off an 80 PLUS gold certification, a single +12V rail, modular design and an impressive 5 year warranty.  80 PLUS gold certification means this power supply will run 87% efficient at 100% load.  80 PLUS gold is the second highest certification given to power supplies only out-done by the 80 PLUS Platinum certification.  Today we will be taking a look at the 850W version of the ZX Series power supply.

Enermax NAXN 82+ 750 W Power Supply

Enermax NAXN 82+ 750 W Power Supply

The NAXN is the latest power supply series from Enermax, and is subdivided into three sub-series: the NAXN, also known as Tomahawk II, featuring 350 W, 450 W, and 500 W models, with no 80 Plus certification; the NAXN 80+, featuring 350 W, 450 W, 500 W, and 600 W models, with the standard 80 Plus certification; and the NAXN 82+, featuring 750 W and 850 W models, with the 80 Plus Bronze certification and modular cabling system (a feature not available on the models from the other two sub-series.) Let's see if the new Enermax NAXN 82+ 750 W is a good option.

In this review we will be looking at the Toughpower Grand 1050w power supply from Thermaltake. The Toughpower Grand is a new design aimed at providing the highest efficiency while still delivering clean and reliable power to enthusiast and gaming systems.
