Today we're taking a look at a unit coming Corsair's latest line of Power Supply Units, the 750 Watt TX750W. Like many other memory chip companies in the industry, Corsair has gradually taken strides into other realms of computer hardware outside of their computer memory emphasis. With a relatively hefty MSRP of $199.99 (or the street price of about $120 after rebates), can the TX750W deliver? Lets find out shall we?
So here are the specs of the TX750W 750W Power Supply Unit, directly from Corsair's main page
|Corsair TX750W Specifications: Model CMPSU-750TX|
|AC INPUT||90-264V ~ 10A 50/60Hz|
|MAX COMBINED WATTAGE||180W||720W||9.6W||15W|
|TOTAL POWER: 750W|
So what comes in the box is basically the manual, the AC power cord, a case badge with a couple of cable ties, and the TX750W unit itself.
The PSU itself comes with a plethora of power connections:
There are obviously some benefits and some downsides to this large number of connectors. For one thing it can be a potential mess for those who don't need these many connectors but luckily all the cabling is nicely sleeved. With the supplied cable ties one can remedy the issue of dangling cables.
A nice thing about the cabling is that there are 3-4 connectors on each cable, making it efficient for the minimalist to hook up to four components using one cable. This can definitely add to less clutter in the end and the sleeves on the cables make it that much better. One thing also worth noting is the fact that the PSU uses a 120mm fan to cool itself, making it not only a potentially powerful addition to your system but also a quiet one. Corsair definitely put a lot of attention to detail on this line because we notice that there were no sharp edges to the casing and also took note of its nice matte paint.
For those who intend on running high-demanding graphics card(s), overclocking their GPUs and/or CPUs, and/or running a ton of optical and hard drives, this unit looks like it has more than enough for the enthusiast gamer. Let us see if it can handle what it was built to do. Off to testing we go...
|Processor||AMD Athlon XP 3200+ (Barton Core)|
|Motherboard||Gigabyte GA-7N400 Pro2 (nForce2 Ultra 400)|
|Graphics Card||XFX GeForce FX5950 Ultra|
|Memory||Corsair TwinX1024-3200LLPro (2x512MB)|
|Hard Disk Drive||Western Digital 200GB WD2000JB|
|Optical Drive||Lite-On 20x DVD Burner DH-20A4P-04|
|CPU Heatsink||Thermaltake Volcano 12|
|System Case||Lian Li PC-A05B|
|Operating System||Windows Vista Home Premium|
A feature the Corsair TX Power Supply line touts is the ability to supply ample, efficient power to your PC rig while doing so quietly. So whats our verdict on this claim? Comparing it to my relatively quiet Allied AL-A400ATX 400W unit, the Corsair was more or less on par. With a low hum, I wouldn't say that the TX750W was silent but it certainly wasn't loud either. If you were to place your case under your table or store it under a cabinet I would say you probably wouldn't notice the presence of the PSU fan.
Impact on Temperature/Air Flow
After installing the TX750W I noticed via Speedfan lower temperature readings across the board (relative to my old Allied 400W PSU). This can be attributed to several features of the PSU: its organized cable management in conjunction to its ability to provide stable current consistently over a long period of time to the whole system. Although the number of connectors had me nervous as to its impact on airflow in the case, the supplied neckties took care of that. Overall a boost in airflow also led to a decrease in temperature in the case.
|Allied 400W Load||Corsair 750W Load|
In testing the stability of the power supply unit and its ability to provide ample current over a long duration, the following programs were run simultaneously for 6 hours to maximize power consumption and CPU, GPU, and RAM use:
|Prime95 24.14 - Self-test||CPU|
|Windows Media Player 11||HD Video Playback – CPU, GPU|
|Windows Media Center||DVD Playback – CPU, GPU, Optical Drive Spinning|
|Speedfan 4.33||Monitoring Purposes|
So after rigorous testing of the TX750W, our staff felt that its plentiful number of connections, its ability to supply ample amount of power consistently over time, and its quiet performance makes it a very strong competitor against other units in its price range. With the hefty price tag however, it would be hard to justify its purchase for the moderate gamer. However for those who intend on overclocking their CPUs/GPUs, utilize the dual SLI graphics card system, and/or add a generous regiment of optical and hard disk drives, this unit (or at least something of this caliber) is an essential must.
Although the Corsair is one of the better power supply units we have looked at, its price point might fend of the average Joe on a budget trying to build a decent gaming system. Nonetheless because of its stellar performance, we at SLCentral are giving the Corsair TX750W Power Supply Unit a rating of 8.0/10.
