Auch wenn hocheffiziente Netzteile allein aus einem aktuellen Rechner noch lange kein Energiesparschwein fabrizieren, so sind sie doch in aller Munde. Dabei wird gerne übersehen, das der Energiebedarf vor allem davon abhängt, was an Komponenten im PC schlußendlich verbaut werden. Wer beispielsweise ein aktuelles Sockel 1366 System mit einem schnellen Core I7 Prozessor komplettiert und dazu eine schnelle Nvidia oder ATI Grafikkarte garniert, darf sich nicht wundern, wenn sein neues System trotz effizientem Netzteil mehr verbraucht, als das gerade Ausgemusterte. Es ist wie bei einem guten Essen, die Zutaten entscheiden den Geschmack, nicht die Speisekarte. Aber entfernen wir uns nicht zu weit vom eigentlichen Thema, denn letztendlich geht es völlig überraschend um ein neues Netzteil aus dem Hause Xigmatek.
Cooler Master stellte in den letzten Monaten eine Reihe neuer Netzteilserien vor. Neben Kraftpaketen mit bis zu 1100 Watt (UCP-Serie) wurden auch noch drei Serien vorgestellt, welche auch Netzteile im unteren Leistungsbereich anbieten. Dazu gehören die GX-, die Real Power- sowie die Silent Pro-Serien. In unserem heutigen Review werfen wir einen Blick auf das 700 Watt starke Exemplar der Silent Pro-Serie, welches nicht nur genug Leistung auch für SLI-Systeme bereitstellt sondern dabei auch noch angenehm leise zu Werke geht, so zumindest die Versprechen seitens Cooler Master. Ob dies auch in der Realität zu trifft, erfahrt ihr auf den folgenden Seiten.
eTeknix has been absent from the world of power supply reviews for around 18 months. Ever since our Sunmoon ATE SM -268 Load Tester broke we have been left without enough test equipment to do a “proper” power supply review. By proper we mean not simply loading the system with VGA/CPU components and taking motherboard readings with programs like OCCT, neither do we find using a multimeter is accurate enough. Our definition of proper power supply testing at eTeknix has been to use a dedicated power supply load tester. Just a week ago we took a trip to Hamburg in Germany where Enermax kindly allowed us to test a whopping 29 power supplies on their Chroma power supply load tester.
The first of those power supplies we tested for review was the XFX Pro 750W Black Edition fully modular power supply. This power supply from XFX is actually manufactured more or less entirely by Seasonic and is based upon the Seasonic X-750. XFX is actually one of Seasonic’s OEM partners. With 750W of continuous power over a single 12 volt rail the XFX Pro 750W power supply is designed to power the most demanding gaming systems with a single ultra high performance GPU or a pair of mid-high end GPUs.
Furthermore the XFX Pro 750W Black Edition uses a fully modular design meaning it is entirely capable of giving you a clean looking system. What’s more impressive is every cable is fully black while all cables, except the motherboard 24 pin, use “flat” black cables for easier cable management. Furthermore the power supply features a hybrid fan switch that allows you to switch between an “always on” or “hybrid on/off” fan mode. The always on mode means the fan always spins and varies with temperature while the hybrid on/off mode allows the fan to turn off at low loads. The option to choose is indeed a very nice feature.
On top of all that the XFX Pro 750W Black Edition power supply is one of the most aggressively priced power supplies on the market and comes with a 5 year warranty, yet has performance that beats most of its competitors if the Seasonic X-750 is anything to go by. But without any further ado, let us proceed on to this XFX Pro 750W Black Edition power supply review and sea how this product stacks up.
When you think of quality power supplies, a few names always spring to mind- Antec, Corsair and of course, Enermax. They are one of the more established companies, being around since 1990, and have made a reputation by consistently producing some of the finest power supplies on the market such as the Modu87+ we reviewed previously.
Sentey's new Platinum rated power supply performs great but, has other issues that need to be addressed.
The EarthWatts Platinum is the latest power supply series from Antec, and will be available in 450 W, 550 W, and 650 W versions, coming with the 80 Plus Platinum certification. This new series will reach the North American market next month; we were able to get a sample before its official release. Let's see if the 650 W model is a good option.
500 watts is a popular segment these days. It's more than enough for powering an Ivy Bridge or Haswell CPU and a single mid-range or high-end graphics card. There's a lot of competition in the pricing in this segment. Spending money on a decent PSU is not a small part of the total price of building a capable PC system. For this reason manufacturers try to keep prices for their 500W PSUs as low as possible.
Can the improved Thunderbolt Plus offer anything more compared to the standard Thunderbolt power supplies? We put it to the test to find out!
The EVGA 600B 600W Power Supply is an affordable solution for anyone who's on a budget, but needs a quality PSU. It's 80 Plus Bronze certified, has a single +12V rail, comes with a quiet 120mm fan & a 3 year warranty.
Sitting at the top of OCZ's recently announced Champ1on Series of Fatal1ty PSUs is the 80Plus Gold Certified 1000w model with modular cables and very distinct styling. We have that very version on our test bench today and will find out if gamers should be putting it at the top of their shopping list for new system builds... after all we all need a new system with AMD and NVIDIA throwing out new GPUs almost weekly.
