## Questions & Answers

**Q: What are the dimensions of this PSU in MM. Better Yet, Does it fit on Cooler Master Elite 110?**
A: 6.25 inches or 158.75 mm front to back. 5.5 inches or 139.7 mm side to side. 3.5 inches or 88.9 mm in height. Don't know if it will fit in the cooler master case.

**Q: im considering buying this to replace generic PSU i have. how long are the cables??**
A: I have an ATX Full Tower case for my gaming rig, and all of the cables included reach fine. I had a little trouble with the GPU power cables, but with a little cable-management it reaches perfectly. Overall this is an excellent, quiet and efficient power supply. 5 months now and no issues, plus it has a 5-year warranty.

**Q: is this a good alternative to the corsair hx750 if i am buying an  intel® core™ i7-6700k , msi  atx ddr4 motherboardz170a and gigabytegeforcegtx980ti?**
A: Hello:The power supply you are considering is rated as a Tier 1 Power supply - The definition of a Tier 1 is:"The highest quality and most stable Power Supply Units available. Protected by industrial grade protection circuitry and can output wattage at a rated maximum temperature of 50°C or below. These units are also Haswell certified, meaning they can cope with the C6 and C7 sleep states of 0.05Amps without triggering the under-current protection switch. May even go over labelled wattage and still work until it safely shuts down"So, it is a safe bet that this XFX power supply will be a great power supply for your new rig.

**Q: Can this psu power two xeon cpus? thanks**
A: It depends on the total power drawn by your PC. I suggest you use one of the online PSU calculators where you can enter all of the peripherals in your PC to work out the PSU size required. I advise against buying the XFX Pro 850W since I had two fail in two years due to a faulty +5V standby circuit which I think is probably a design fault. I'm now using an EVGA 850W PSU which has a 10 year warranty. This would be a better buy than the fault prone XFX PSU.

    Silent, Hybrid Fan Switch, by Seasonic. Great build quality.
  

*by H***H on Reviewed in the United Kingdom on 16 July 2016*

Still working perfectly after a year (bought May 2015)Fully Modular means you no cables attached, only plug in the ones you require. This XTR series is made by Seasonic.Nicely boxed, securely wrapped and foam enclosed PSU unit, with a separate box within for the plentiful cables, User Manual and came with a 3-Pin UK Plug. The cables are not fancily sleeved but a decent no-thrills sleek black,Its very silent at 16dBA but if even the quiet fan airflow is an issue, there is also a 'Hybrid Fan Control switch' (located where you plug the modular cables in) which enables passive cooling i.e. fan off when not required and auto turns on when it gets to a certain temperature (20% Load or 25°C), which due to its location and labeling, cannot be confused wit h the Power switch at its regular locale where the mains power cable plugs in.Would have liked to see the images / more illustrative features stated in product description, so posted those of the box here too for those like-minded.

    A good PSU, high quality and very quiet.
  

*by N***J on Reviewed in the United Kingdom on 19 July 2015*

A good PSU. The item is currently under review because it was delivered with an American 2 pin plug. Not an issue if you have a spare UK one, however may impact any warranty claim. Easy to fit the modular cables, space saved by only using the ones needed. Clever hybrid fan that is linked to power usage. *important* after fitting and switching on at the rear of the unit, wait at least 5 seconds before attempting to switch on the PC, there appears to be some sort of delay, as if the unit is either calibrating itself or checking your system. This took me by surprise and made me think I had a duff unit. *further update* after several weeks of using, I am impressed with the quality of this unit. The hybrid fan switch keeps it very quiet, the lack of UK plug was easily rectified, and the modular cables are so much better than having to find room for unused ones.

    Good power supply
  

*by T***P on Reviewed in the United Kingdom on 13 June 2015*

The unit which was delivered initially turned out to be faulty (I got no power out of it), which was disappointing as this has great reviews on other sites. However, since Amazon were fantastic about sending me a replacement, I won't let that affect my rating.Pros:- Delivers power to my newly built PC perfectly- Fully modular- 80+ Gold rating- Not too loudCons:- Some of the cables are a bit short- The 24-pin motherboard connector cable isn't very flexible
