It has been quite a while since we looked at a Power Supply here at BCCHardware and this is a first that we've had the chance to look at a Rosewill product. Today, we've got the semi-modular Tachyon 750W unit on our bench and will find out if this Power Supply has more than just a little bit to brag about. It comes with a 80 PLUS Platinum rating and a fair amount of AMPs on the single +12v rail.
If you are an enthusiast with a couple of graphics cards, a fast CPU and a few drives, this unit claims to provide more than enough power to your system. It is our job to find out if those claims are valid, or if this is yet another PSU that talks big, but cannot deliver.
The Rosewill Tachyon 750W Platinum PSU arrived just before CES 2013 and we are just getting caught up enough to really punish this unit and see if it can hold up under pressure. This PSU is fairly compact in size - thanks to the relatively "small" power output (750W) as well as the Platinum rating. In our experience, as power supplies get more efficient and gain higher ratings, we see the size decrease as there is less waste energy and less heat output. This helps keep things nice and compact.
Once you pull the unit out of the box you can see that there is an adequate bundle included. The modular cables come in a nice case and there are some simple cable ties for cable management. It's nothing fancy, but sometimes simple is good.
The 750W Tachyon comes with a few cables attached as you can see below. The basic cables that you'll be using with pretty much any system come hard-wired to the box and they include the 24-pin motherboard cable, an 8-pin CPU cable as well as the 4+4-pin motherboard cable. A single PCIe cables with a couple of PCIe connectors on it is also hard-wired to the PSU. While not all motherboards require both 4+4-pin and 8-pin connectors, this PSU is built for some pretty hefty applications.
On the next page we'll take a closer look at the Tachyon-750 and dive into the features and specifications.
