Performance (40% of the final score) - ok, this one's going to be easy. This unit didn't meet its rated spec, not even by a long shot. And it died in the hot box at a temperature of forty two degrees. So, I'm taking all ten points off for that. But, I'll have to add some points back on. One for passing the overshoot transient test for the 5VSB rail, and one for the well in spec ripple and noise when the unit wasn't clearly being asked for more than it could handle. That gives this unit a good solid 2 here.

Functionality (20% of the final score) - this unit, going by the cabling, would have you believe that it can really do 1050 watts. There are enough connectors for three video cards, enough SATA and Molex connectors to choke a Zebra, and the dual cable exit does help a bit with cable management. It's just too bad the cabling itself is too thin gauge to matter, and there's that whole "can't do 1050 watts" thing this unit has going on, too. 5.

Value (30% of the final score) - for the low, low price of $104.99 at Tiger Direct, you too can own a good looking unit with heatpipes that thinks it's twice as powerful as it really is. If you're in Canada, the price goes to $138.99 Canadian. Take a look at Tiger Direct's selection of 500W units for a second - see that? You can get decent 500W units there for half the price this thing costs. This is not that decent of a 500W unit, and it's no kind of 1050W unit at all. 1.

Aesthetics (10% of the final score) - yep, it does look good. Even the very overrated units can end up with a good score here, and this one's getting a 9 from me.









Total Score



Here's the good news - the Diablotek RPM-1050 is a good looking power supply. The cables are nicely sleeved, the color scheme is lovely, and it comes with some good looking velcro cable ties. Here's the bad news - everything else. This unit would not do over six hundred watts at room temperature without some serious issues, including severely out of spec ripple and severely out of spec voltage numbers. The 12V secondary parts are rated at 60A combined while the power supply itself would have you believe it is capable of 78A at 12V. This unit, quite simply, is a 500 watt unit pretending to be twice as powerful as it really is with a heatpipe added purely as a gimmick. Buy something else, people.

The Good:

  • looks great
  • good 5VSB power on transient suppression
  • decent ripple suppression below 500W

The Bad:

  • questionable quality capacitors

The Mediocre:

  • everything else
