Should you want more gaming performance from the Predator, perhaps if you want to play at high detail on one or more large displays, Acer has also provided you with enough upgradability to add a second graphics card. The 750-watt power supply should be enough to handle a second GeForce GTX 470 graphics card, and the X58 chipset ensures that you have the necessary PCI Express graphics card slots.
Further expansion options are plentiful. You get three spare hard-drive slots via the front-loading drive trays. You also have room to add a second optical drive. All six RAM slots are taken because of the 12GB of memory already present, but expansion card options include two free PCI Express 8x slots, a spare PCI Express 1x slot, and an open standard PCI slot. That's plenty, and allows not only a second graphics card, but also a wireless networking card, a TV tuner, a sound card, or other extras.
You also get lots of options for connecting external devices to the Predator. The front panel features five USB 2.0 jacks, along with a mini FireWire input, two analog audio jacks, and a media card reader. The back panel has six USB 2.0 ports, standard FireWire, an Ethernet jack, S/PDIF digital audio, 7.1 analog audio jacks, and two eSATA ports. There's no USB 3.0 on this system, but that's not exactly a crucial feature yet. In general, though, the Predator has all of the modern inputs and outputs we expect to find on a performance-oriented gaming desktop.
|Acer Aspire Predator G7750-U222||Average watts per hour|
|Off (60 percent)||0.32|

|Load (5 percent)||315.18|
|Annual power consumption cost||$64.30|
The Predator's power consumption comes in at the bottom of our comparison chart, but it's still in an appropriate range given its performance and its components. Anyone shopping for a "green" gaming PC will find out quickly that the performance trade-offs for more aggressive power efficiency are generally too demanding, so we have few issues with the Predator or other PCs in its class using more power than a typical mainstream PC.
Acer's service and support policies for the Predator provide this system with one year of parts-and-labor coverage. You get toll-free phone support, with lines open 24-7 at 866-695-2237. Acer's Web site, however, is relatively useless for support. You get driver downloads for the system, accompanied by a generic FAQ. That's it.
