XFX Pro Series 850W Power Supply Review

The XFX 850W Pro Series Power Supply certainly has not failed to impress, it combines a great design ethic with rock solid build quality. Of the three supplies in this particular range (850W, 750W, 650W), it maintains the lowest ripple results and delivers the highest efficiency levels, by a small margin.

The Seasonic design displays very balanced results across all our testing with no problems or inherent weaknesses. As a 80 Plus Bronze certified unit it is pretty much as good as it gets. Noise levels are acceptable and the large fan is capable of ensuring good airflow even when under full, sustained load.

The XFX Pro Series 850W is one of the finest value for money high performance units on the market … retailing for £90 inc vat, it is sure to find its way into many demanding gaming systems over the next couple of months.

KitGuru says: The 850W Pro Series unit combines great performance characteristics and high efficiency at a very reasonable price.

  1. This is the one I want, seems great value for under £100.

  2. Ah at last 🙂 looks to be just as good as the others, with a little more headroom for futureproofing. l;ets hope 6000 series cards arent like fermi design !

  3. Seasonic have done well for XFX with this range. the price is spot on.

  4. I was waiting on the review for this one, just in case it was a poor unit. It would be my luck to get the one that sucked.

    Glad to see it doesn’t. going to order one this weekend.

  5. Best value of the three of them. good efficiency, great ripple. and 90 quid. cant beat that for an all round product.

  6. Most 850w are over 100, so in t hat point alone its great value. no real faults, apart from the fact you could maybe get one with lower noise for a little extra. not sure that would matter. most gamers only have systems under 500w load anyway, would be hovering around 50% load which is ideal for the best results.

  7. You probably find most gamers are under 400w maybe even nearer to 300w. even today.

  8. Yeah, its a good point, most gamers only use a 5770 or similar. so nearer 300w is probably more accurate under load. but I agree, 850W seems the best value of the three of their units. its still under 100 quid and its got bags of power for next generation or later.

  9. Seasonic have created some marvellous products here. those ripple results are so low, extremely impressive.

  10. Ordered two from Scan, shall keep one for a christmas present for my bro.
