Bit-Tech published a review of Corsair's TX750W power supply
Corsair is onto another winner with the TX750W, as it has proved itself to be an awesome PSU. It's clearly far from the best cooling design available, but it has the best components we've tested to date.Corsair's TX750W power supply Review
What makes the deal even sweeter is the fact that the Corsair TX750W is even cheaper than some of its competitors too. At £88.60 (inc. VAT), it's cheaper than the PC Power & Cooling 750W Silencer, which costs £95.66 including VAT. In contrast, the Enermax Infiniti 720W now looks seriously expensive at £128.23. Even the Gigabyte Odin GT 800W PSU is significantly more expensive at nearly £125.
There are a few 750W units for less, but we honestly wouldn't bother looking much further than the TX750W. In fact, it's questionable whether units that cost more than the TX750W are worth considering over this unit at the price that Corsair is asking for it.
The HX620W is a good £18 cheaper, but it's also 130W less powerful and modular so there's still a clear differentiation between the two styles that are clearly designed to suit different markets. Unless you've got your heart set on a modular unit, the Corsair TX750W manages to undercut many 650-700W units on price, while clearly not skimping on quality!
