I can get the Truepower New 750W and Corsair HX 650w at the same price (though considerably more expensive than the 650w TX); these are the only two non-premium PSU I can find at reasonable prices. Would you say the TX/HX series is outdated then? Sorry for highjacking the thread.
The reason that Oliver said that the TX series shouldn't really be recommended any more is that they present average performance at a price point where it's possible to find a better power supply in. An example of that would be the Antec TruePower New 750W - it's cheaper or the same price as the TX750, offers the same warranty, is a much better performer, higher max output on the 12V rail and is partially modular.
There are often better power supplies for the money in every wattage range out there.
The HX750 and HX850 are not outdated, but the rest are. They're based on a CWT DSG unit, whereas the rest of them are SeaSonic S12E units (for the HX520, HX620 and HX650) and the HX1000 is an older CWT PUC unit. The HX750/HX850 are amazing power supplies, and offer very good value for money, though there's the Thermaltake ToughPowers based on the same design as them for around the same price, and the SeaSonic M12Ds which are around the same level of performance for around the same price.
The TX950 is a great power supply though. CWT DSG like the HX750/HX850 and is a pretty awesome performer. It has no competition because it's one of the only 100% hardwired high-end PSUs out there. It's what I'd choose if I needed ~1000W and I had a case cable of taming the masses of cables that come with it.
To copy/paste myself from another thread:
CX400 is beaten by the OCZ StealthXstream 400W in price and performance. The SeaSonic S12II 380W is also a better PSU, and has the same 12V rail capacity IIRC.
VX450/HX450 is beaten by the SeaSonic S12II units.
VX550/HX520 is beaten by the Antec TruePower New 550W
HX620/HX650/TX650 is beaten by the Antec TruePower New 650W.
TX750 is beaten by the Antec TruePower New 750W.
HX750 isn't really beaten by anything other than the SeaSonic X-750, but the SeaSonic M12D/S12D is pretty much identical in performance for a very similar price.
HX850 is again, pretty great. M12D/S12D match it. ToughPowerXT 875W matches it too, same CWT DSG platform.
TX950 is a great PSU, nothing's around the same wattage level that can compare for the price. The Enermax Revo 85+ is about the same performance-wise, but it's a lot more money.
HX1000 is beaten by a handful of units. The OCZ Z1000, the CoolerMaster RPP 1000W, any new Enermax unit, the Antec CP-1000 (which can only fit in certain cases, to be fair).
Edit: personal experience has very little to do with how good a PSU actually is. Many people run horrible, generic power supplies for years, but that doesn't really make them good. A real review is the only way to know how good a power supply is. That should include load testing using a special purpose load tester, voltage ripple and noise measurements, testing in a hot box/well above room temperature, about 50C if you really want to stress a PSU and a detailed analysis of the dissected power supply.Edited by meticadpa - 6/10/10 at 11:19am
