Changing power supplies?

[ManofGod]

I have a thermaltake Toughpower 750: Thermaltake Toughpower 750

I am considering getting this: Thermaltake 850 Watt TR2 RX

The reason I am considering this is because my 750 only has 2 PCIe power connectors. What that means is that I am using 2 x 2 molex to 1 PCIe adapters for the second card. Also, the 750 is split rail well the 850 is single rail design.

I have: 2 x Powercolor 6950 2GB with unclocked shaders.
2 x 1TB harddrives
1 x Bluray reader
Phenom II X6 1090T at 1.45 volts at 3.9 GHz
Asrock 990FX Extreme 4 mainboard.

Do you guys think it would help overall or should I just stick with what I have? I do not seem to have any stability problems. However, about 2 years ago, one of the Sata power connectors shorted out but otherwise, nothing seem to have any problems.

Don't do this. You see, despite the "850W" rating, that TR2 RX PSU is not a true 850W PSU at all - but is really only a 580W PSU with an "850W" label on it. Worse, the entire TR2 series PSUs are of significantly lower quality than any of the Toughpower series. As such, going from any Toughpower to a TR2 RX 850W would be a substantial downgrade in both quality and performance.

Though to be sure, you should consider replacing that 750W Toughpower since it is one of the earlier units that were based on a first-revision CWT PSH platform, which really can't be trusted above 600W or so. In addition, you should also consider a brand other than Thermaltake at this price point: The current Thermaltake-branded PSUs are fairly overpriced for the quality and performance that they actually deliver. Consider a Sea Sonic, Corsair or Antec at this price point.

Ok, thank you for the advice. Sounds like when I do purchase a new one, a seasonic model should do well for my needs. Thanks again.

Your 750W Toughpower is a single-rail PSU, although that isn't something to be concerned about either way.

Nonsense.

Perhaps I received misleading info about some of the various Toughpowers. Although I do know for a fact that the Toughpower XT is CWT DSG-based.

The "nonsense" part is your assertion that the original PSH units are not reliable above 600W.

I've read some reports about DC quality problems above roughly that amount on that platform although some companies are better than others in controlling these potential issues. In the case of that 750W Toughpower, Thermaltake designed the PSU but subcontracted its manufacture to CWT, who then used the PSH platform as the basis for that unit. In Thermaltake's design, the capacitors that CWT would have normally used were replaced with higher-quality ones.

The "850W" TR2 RX model is a completely different animal: In that line, Thermaltake simply took an off-the-shelf HEC/Compucase unit and slapped Thermaltake's own label on it. Note the UL number on the TR2 RX unit: For most of that line of PSUs, the UL number is traced to Compucase (whose parent company turned out to be HEC).
