Today on the new test bench we have the latest Antec HCG-620M power supply, a 620 modular unit targeted towards the mid-end segment of the market and more specifically gamers.
The latest Antec High Current Gamer 620W M is a modular version of the HCG-620 i had the chance to test a while ago but since modular cabling affects the performance of a power supply i thought it would be nice to see just how good the new HCG-620 M really is. Certainly the high current gamer series is not Antec's top line of power supply units but it offers a very good performance/price ratio which is indeed what most gamers are after when looking to buy a new unit.
The box contains the HCG-620M power supply placed inside a bag, the user's manual paper (product overview), 4 mounting screws, AC power cord and the modular cables.

Today we are going to be taking a look at one of the newest power supplies in the EarthWatts line the Platinum 650W. This 650W power supply has an 80PLUS Platinum certification, the highest efficiency mark for power supplies. With this power supply you will ge 92% efficiency at 50% load and 89% efficiency at 100% load.
This power supply is not modular as many high efficiency power supply are not. So all of the cables are connected to the power supply. All of the cables are nicely sleeved. Taking a closer look we have the single 24pin ATX power connector, one 8pin CPU power connector, two 8pin(6+2) PCI-Express connectors, four molex connectors, six SATA connectors, and a single floppy connector.
This is the first 80PLUS Platinum certified power supply that we have seen from Antec and for an for the entry-level segment they have done a pretty good job. In our testing the voltage regulation on all three rails was just over 1% which is really good. You can not go wrong with the Platinum rating either. This will keep your electricity bill down especially if you are using this power supply on your main rig.

Today we are taking a look at the new ProSeries 1000W Platinum PSU. It should offer enough power for nearly everyone out there and do so at high efficiency. DC output quality was OK from start to finish. Starting out, we were clearly able to see a ripple on the scope during Test 1 where we measured noise at a low 12mV peak to peak.
This steadily increased as the loads also increased. By the time we had reached around 50% load, the unit ripple had crept up to 33mV. Under full load, we saw that the noise on the 12V rail had crept up to 53mV.
The XFX ProSeries 1000W is rated for 80Plus Platinum efficiency. This means that the power supply must perform at 90%/92%/89% efficiency at 20%/50%/100% loads respectively. As you can see, the XFX ProSeries managed to score a pass while on our test bench. There were several times that the power supply was right on the edge. This would explain why the 1050W ProSeries PSU is only rated for 80Plus Gold efficiency.
XFX has a great power supply with the ProSeries 1000W. It is loaded with features, has great cable selection and a ton of power to handle just about whatever you can throw at it.

The ZT Series is found within OCZ’s High Performance category and is significant due to its fully modular cabling system. Most PSUs that name themselves modular refer to a certain group of cables that are removable but the ZT boasts a completely modular configuration – even the motherboard ATX cable is detachable. The ZT series adopts 80 Plus Bronze certification and is available in following variants 550W, 650W, and 750W. Today we will be taking a look at the first model and lowest rated wattage – 550W. Ideal for those who are looking to build a gaming system with a powerful graphics card and typical assortment of drives and devices.
Choosing the right PSU is an important decision for the enthusiast because it is the backbone of any system. The ZT 550W is an affordable PSU, not only is it within the same price-range as some of the other 500W PSUs that aren’t modular it obviously adopts this fully modular characteristic.

The new ZS Series 550 Watt power supply has changed from a multi rail to single rail design and uses higher grade components with 80 Plus Bronze Certification. OCZ have also upgraded the size of the fan to 135mm to offer better cooling proficiency. Efficiency from the supply is very good for a bronze rated unit, achieving almost 86% at around 50% load. It falls to 83.35% efficiency at full load. The active fan helps maintain good temperature variables, rising to a 10c above ambient intake at full load. Technically, it is a basic, yet tried and trusted Sirfa implementation and is an improvement over OCZ’s older ‘value’ designs. The new product features higher efficiency, a single rail output and Japanese capacitors.

The ZS Series is the latest mainstream power supply series from OCZ. Available in 550 W, 650 W, and 750 W versions, these models don’t come with a modular cabling system. The cable configuration is excellent for a mainstream product, with eight SATA power connectors and two video card power connectors.
The OCZ ZS Series 650 W proved to be an outstanding mainstream power supply. It can really deliver its labeled wattage at high temperatures, and we could pull up to 780 W. Voltages are closer to their nominal values than required (3% voltage regulation), noise and ripple levels are low, and it provides terrific efficiency for the market to which it is targeted, between 84% and 86% when we pulled between 20% and 80% of the unit’s labeled power (i.e., between 130 W and 520 W), and 82% at full load (650 W). Another highlight of this unit is the presence of eight SATA power connectors.

Today we are taking a look at Corsairs CX430V2, a 430W power supply in the Builder series. It doesn't boast a ton of cables and connectors, lacks the wattage to power a small village, and even carries the lowest 80Plus certification that a power supply can get. What it does boast is one heck of a cheap price tag and the ability to provide enough power for almost every non-enthusiast level home or office computer.

The Earthwatts EA 750W is supplied without a power cable, a move which won’t appeal to everyone. Antec are aiming these models as ‘upgrade’ units. I spoke to them when they sent over the 650W and 750W units and they felt that many people already have several power cables and that another could be deemed as an unnecessary extra. As I said before, there is certainly a tinge of helping ‘mother earth’ to the whole concept but it bewilders me. Best to just get into the review.
So whats new with this latest model? Antec are still using Delta as their OEM partner, but the latest range is 80 Plus Bronze Certified. The new units are ‘green’ and they have received some performance improvements. The 750W we are reviewing today is also equipped with a larger fan, always a good sign.

The Corsair TX750 and TX850 power supplies have now been around for some time and I guess rather than discontinue what has proved to be a very successful product Corsair have decided to keep the model going a little longer and offer a few improvements with the V2 units. This time around OCC will take a look at two power supplies from the V2 range, the TX750V2 and TX850V2 power supplies and see just what improvements, if any, Corsair have made.

PC Power & Cooling has an established reputation in the power supply market, but since they came under the OCZ umbrella there haven't been many new products. Could PC P&C maintain the quality they were known for? Would they have the autonomy to continue engineering solid products? We're looking at their latest release, the Silencer 760W, in the hopes of finding those answers. The PC Power & Cooling Silencer 760W features an 80Plus Silver certification, coming with an astounding 7 year warranty and a competitive price of $130. It's also got an interesting front-to-back cooling design, bucking the recent trend of large bottom-mounted fan designs. Can it measure up?

Antec package the High Current Gamer range in a large, sturdy box which gives some basic information on the front and numerous specifications on the other sides. Inside we find the PSU protected by a second layer of cardboard and bundled with it is a mains plug, installation screws and a quick start guide. The full manual is available as a download from Antec's website. Antec also wrap the PSU in a cloth bag for further protection and the cables provided are held together with a re-usable tie. In terms of key features we have a unit which has one +12v rail rated for 48A and as well as being a 620w model Antec are keen to point out that this is 620w continuous at 35°C, not peak which is the rating some other manufacturers use. Mixed with this high specification is an 80 Plus Bronze certified unit which means it has passed certification of 82% efficiency at 20% and 100% load with 50% load rated at over 85%.

  | The StealthXStream2 is the successor of the original OCZ StealthXStream power supply. Like the original, the StealthXStream2 power line of power supplies is designed for the price conscious value seeking performance crowd with models ranging from 400W to 700W. We will be looking at the 600W version today. Starting off with our first set of open air tests the unit managed a 85% efficiency rating at 50% and 80% load and 84% at 100% load. The 3.3V and 5V rails managed very well, but usually these rails aren’t the ones that we’re too concerned about. From our 50% load test to 100% load the 12V rail moved from 12.05V to 11.96V which at most a change of less than half a percentage from specification. An excellent showing here. Read more... |
