Thermaltake 750W TR2 RX Power Supply Review


You Must Choose... But Choose Wisely

Ah, the heartbeat of the machine.  The driving force that sends every pulse of electricity and every turn of the fan.  The most important part of the computer and the most dangerous part are one.  I’m talking about the power supply.  Without it, every other part of your computer is just a bunch of silicon, wire, and metal sitting in a box.  It must be reliable, it must be powerful, and it must look good.  Well, that’s the consensus these days, isn’t it?

Thermaltake has tossed us another bone with the TR2 RX 750-Watt power supply.  It looks great, its 750 watts strong, and today I’ll find out how reliable it is.  Thermaltake doesn’t disappoint very often, and I have high hopes for this particular piece of hardware.  I’m going to be testing it on my usual testing rig, a 2.9Ghz Athlon 64 X2 dual core with 2GB of 800Mhz RAM.  I also have six 120mm case fans all running at once, two DVD-RW drives, two SATA HDDs, and an ATI 4870 video card.  Normally, this setup would warrant at least a 500W power supply, so the TR2 should have no trouble keeping up.

Before we go into the box, here’s a little info on the PSU:
