Ultra X-Pro EE 600W – Details
The Ultra X-Pro EE 600W power supply features a traditional steel enclosure with a black-chrome finish. The X-Pro 600W is a high-efficiency unit that is primarily targeted towards enthusiastic gamers.
The power supply uses a single, large fan on the bottom-side for cooling.
The 135mm cooling fan is made by Young Lin Tech (DFS132512H). This is a high-speed model that has 11 blades and uses sleeve bearings. To help keep things quiet, the fan speed is automatically controlled by the internal component temperature (speeds up as the combined load and temperature increases).
The fan mounting screws and free-flow wire grill are nicely recessed for easy installation of the PSU into a case.
Air is drawn in thru the bottom of the power supply by the large cooling fan and exits thru openings in the front and back. The series of slots across the front helps to minimize hot spots inside the power supply chassis.
The open honey comb grill on the back allows exhaust air to exit the power supply with minimal resistance. The Ultra X-Pro 600W PSU incorporates universal input (automatically adjusts the AC line voltage) and active PFC that adds to the units environmental friendliness.
Ultra X-Pro EE 600W Specifications
Note that the Ultra X-Pro EE 600W power supply supports the older ATX12V v1.3 specification. The newer ATX12V V2.x specification requires all outputs to be limited to 240 VA (+12V x 20A = 240 VA). And because this power supply features a single, high-capacity +12V output, it does not comply with the newer standard. This isn’t necessarily a bad thing as it eliminates potential problems created by current limiting the various +12V outputs. Since each unique PC configuration places different loads on the different +12V rails. If your particular motherboard and video card configuration happens to pull more than the allowed current (20A max.) from say the +12V-3 output, the PC may not operate reliably (or at all) even though the combined +12V output capacity far exceeds what your PC is using.
The X-Pro EE 600W power supply is rated for a combined, maximum output power of 600 watts at up to 40+Â°C ambient air temperature (internal case air temperature). I would prefer to see 50ÂºC instead, as that is the norm for high-end power supplies, but at least a specification is given (and it’s not 25Â°C).
