|Testing the Ultra X4 850W PSU|
We have recently posted our review of the Ultra Products X4 1200W Power Supply and today we are looking at the little brother to the big 1200W unit. We've got the 850W version on the bench and as we dive into the review shortly, you'll notice that there are a lot of similarities between the two units. In fact, the cable package, outward design and even the physical size is virtually identical. It seems that the biggest difference will be inside. The PSU appeals to those that don't need a 1000W+ PSU, but when you consider that this PSU weighs in at $249.99 MSRP, I think the 1200W X4 has more value at $299.99. We'll see how things hold up as we carry on.
Ultra has kept all of the X4 Power Supply packaging pretty much the same. Everything from the 500W to the 1200W PSUs ship in almost identical boxes that show a bevy of specifications, information and a lot of pictures of the contents and cables. All Ultra X4 power supplies come with a 3 Year Standard Warranty and Limited Lifetime Warranty - should you choose to register the PSU on their site. This may give you some peace of mind as it could certainly be the last major PSU purchase you need. Each Ultra X4 PSU meets different efficiency standards, and the 850W version claims to be 80PLUS "Silver" certified. This beats the 1200W X4 as it only makes 80PLUS "Bronze" certification.
850W is probably enough for 90% of enthusiasts with multiple graphics cards as the X4 850W comes with enough cables to hook up a ton of hardware - including 6 PCIe connectors for your multiple graphics card goodness. There is only a single 12v rail in X4 Series power supplies so you don't have to worry about balancing the rails so you don't overload one particular rail. This is probably the best feature of having a single large rail.
While the 1200W unit surprised me due to its small size, I now fully expected the 850W version to be standard ATX size. This makes it very easy to put into your favorite mid-tower case without any issues that can be caused by longer units. It measures exactly the same size as the 1200W version.
You can see that the PSU isn't very large, but this isn't necessarily a bad thing. Power components have got significantly smaller over the past few years as therefore, PSU's don't need to be massively oversized in order to be powerful. Combined with the 80PLUS Silver rating, this unit should remain cool and quiet if all goes well.
