In The Box
Once we get through the factory shrink wrap and open the box, we are greeted with everything we will need to handle the task at hand. Though not modular in design, the cabling harness is fully wrapped in a mesh material to make your task of cable management pretty easy. Also included is a small bundle of Velcro ties that will help you keep that extra wiring out of the way of your airflow path. There is another addition in the form of an added cable harness, but we will talk about that in just a bit.
As noted above, this is not a modular power supply. While it is nice to have this feature, I have found that many manufacturers who are looking to shave the price will generally make use of this layout. It is not a deal breaker as long as the cabling is protected and mounted properly, which is the case with the Thunder 650.
The shell is heavy and very sturdy and has a chrome finish to set off your rig if you happen to have a full sized window in your case. This PSU includes over-voltage protection, includes Active PFC, and has four 12v rails to manage the job of providing power to your hungry components. Each of these 12v rails is rated at 20A while both the 5v and 3.3v rails are rated at 24A. This lower amperage rating on the 5v rail means that this product is designed for newer systems. Whether you want to run an AMD or Intel machine, either of the newer technologies will run fine with this setup, but older Athlon XP systems that need a huge 5v rail may run into some stability issues depending on the components included in the system.
Since modern power supplies tend to run harder than older models, the Thunder 650 includes a 120mm fan on the bottom panel. This will allow ample air to be pulled from your case, through the unit, then expelled out the back, all with a minimum of noise. While operating this PSU I was unable to hear the fan over the system at any time, even when under load. Also of note is that the fan has a blue lighting scheme provided by the blue LED lights installed inside the fan itself.
To allow all that airflow to be properly vented out the back, the folks at E-Power have made use of a mesh covering the exterior panel. While another fan is not included here, I have found in the past that a second fan usually makes little to no difference in the cooling potential of the power supply. Since they tend to be smaller fans to boot, they also tend to add noise to the component.
While we are here, take a look at the back panel. While the power port and toggle switch appear pretty normal, there is an added port on this unit that resembles a PCI-E plug. Though that is not what it really is, it does add to the feature list and is where they get the "3-in-1" label. Let's take a quick look at what plugs into this port and then we will see what we have.
Shown above is the cable assembly that attaches to that port. The 6-pin block will obviously plug into the back of the power supply and the other ends give you the added flexibility of powering an external USB and/or SATA device. Add to this the length of the cable and you have yourself a very convenient means of charging up those devices that make use of a USB or SATA port.
Moving around to the back of the unit shows that chrome finish that was mentioned earlier. It is very finely done and there were no mars in the finish to detract from the overall aesthetics. From this angle you can also see that the cabling harness coming from the casing is properly protected and cinched down close to the exit port. The plastic grommet will keep the wires from rubbing through the mesh and the tying of the harness will keep your cables from flopping around everywhere.
Speaking of the cables, what exactly do we get with this product?
The primary coupling is of the 20+4 pin variety so your power supply will be compatible with either of the two types of motherboards still being used. It also included a 4+4 pin auxiliary coupling, as well as connections for 4 SATA devices, 6 4-pin peripheral devices (Molex) and 2 FDD devices. For graphics there are a 6-pin PCI-E and a 6+2 pin PCI-E connector. If you happen to have a pair of video boards that require a 6-pin PCI-E each, this PSU is rated to handle either an SLI or CrossFire configuration. Of course, if you happen to have a pair of heavy duty graphics adapters, you will be short on connectors, and to be honest, this product isn't designed to handle that type of load.
So far we have the making of a workable power solution, but before we pass judgment, let's see how well this little beast performs in a real-world test, shall we?
