To cut a long story short, the HX750w is every bit as good as it's bigger brother the HX850w. Throughout the testing the voltage and efficiency results were so uncannily similar that if not for the MAX load results topping out at 913w (vs 1084w on the HX850w), we would have happily put money on the HX750w simply being a HX850w with different stickers and less two of the hard-wired PCI-E connectors.
In effect, this positions the HX750w as THE BEST 750w PSU we've tested on OC3D to date. For an extremely reasonable £113 (over at Scan.co.uk
) you get a 750w PSU that not only looks awesome with its smooth powdercoated finish and flat modular cables, but also performs among the best in its class. Efficiency levels rarely went below 90% even when running well above its rated output, and voltages refused to budge by any noteworthy amount no matter what kind of load we threw at it.
So, for the moment at least the choice is simple. If you're looking to power a tri-sli system and need a full six PCI-E connectors, then the HX850w
is the way to go. However, if you're sitting on a small roll of £20 notes and are looking for an awesome PSU to power your single or dual GPU system, then you really should be looking no further than the HX750w.
- Extremely high efficiency at around 90-93%.
- Runs reasonably cool and quiet (from what we could tell over the din of the load tester)
- Excellent voltage regulation on all rails, even in cross load situations.
- Ripple almost non-existant on +3.3v and +5v rails. Also very low on +12v rail.
- High quality internal components.
- Great modular connector system with plenty of sexy 'flat' style cables.
- Well packaged. Hardly any chance of damage during shipping.
- Has a sustainable peak output of 887w when running at 50°C!
- Would quite like for hard-wired cables to use the same 'flat' style cables as the modular connectors.
- Nothing at all
