Corsair unveils 90% efficient power supplies

vrd · May 30, 2009, 3:52pm

To meet the increasing demand of power-conscious devices Ã¢â‚¬â€œ especially PSUs Ã¢â‚¬â€œ Corsair has introduced a pair of new units flaunting a 90% efficiency rating. Built on the success of CorsairÃ¢â‚¬â„¢s HX620, the HX750W and HX850W utilize advanced DC-to-DC circuitry and meet 80 Plus Silver certification standards for up to 90% energy-efficiency. Both effectively diminish the amount of excess heat and wasted energy whilst delivering clean and stable voltages, with an emphasis on low-noise.

Apart from their rated power output of 750 and 850W, it would appear that both units bear near-identical specifications. Guaranteed to sustain their full rated wattage at an ambient temperature of 50Ã‚Â°C, each pack up to 62A on a single +12V rail. As noted, theyÃ¢â‚¬â„¢re up to 90% energy efficient under real-world load and are multi-GPU ready, host 105Ã‚Â°C solid state capacitors, have an active PFC of .99 and comply with ATX12V 2.3 as well as EPS12V 2.91 standards.

The 750W version of the PSU can be found online for about $170, and the 850W adaptation can be had for around $200. It is worth noting that the HX850W was recently stamped with HardOCPÃ¢â‚¬â„¢s EditorÃ¢â‚¬â„¢s Choice Gold Award among well-received recognition elsewhere.

**up to **90% energy-efficiency, 80 Plus Silver certification.

Gr8 post, I wish Corsair kill TX series now.

Good news any idea when those coming to india. I really want those.

Gurpartap_Singh · May 30, 2009, 9:24pm

some would still prefer TX but yeah with this efficiency, it should die. such a mess to manage cables in TX

WingZero · May 30, 2009, 9:35pm

Harocp review testing doesnt mention above 90% efficiency dwindles between 83-88. Nevertheless has very low ripple and outstanding dc output quality. Needs appopriate pricing over here.

yup,..the modular aspect also works in favor of the HX series.

regarding price,..i don’t think they are priced too expensively considering the features.

i absolutely see no reason to continue producing the TX series now.

yet again great PSUs from corsair.

rdst_1 · May 31, 2009, 1:52am

i think the prices are right and i wish to get my hands on one when they arrive

also remember corsair gives 5 year warranty so it is beneficial to pay the price even if it’s on the higher side

_Free_Radical · May 31, 2009, 2:53am

The HX850 comes with 7 year warranty

axeman · May 31, 2009, 3:11am

neat stuff, i wonder when our dealers get their hands on it

shaunak · May 31, 2009, 3:21am

Wonder if they will release lower capacity varients? Something like 450W?

HailStonE · May 31, 2009, 8:03am

Pricing will be around 7-12k as per Techtree…

Aman27deep · May 31, 2009, 10:10am

@ 7k it’ll be totally awesome!

as it has 7 years warranty, it’ll run perfectly for even modern cards 5 years from now!

user65 · May 31, 2009, 10:51am

awesome!! nice to see a 90% efficient PSU from Corsair now, I think Corsair will soon become a major player in PSUs manufacturing like Silverstone and all

sato1986 · May 31, 2009, 11:56am

hey but isnt TX series darn cheap??

i think HX 620 costs same as TX 750 = 7k… No?

i luve tx series for their price.

WingZero · May 31, 2009, 12:16pm

Tx series can only compete with hx for price.

Hx850 oem is again its regular, CWT but using another model DSG series. The unit doesnt deliver 90% efficiency.

SidhuScorpion · May 31, 2009, 12:46pm

TX750 is also 8k now, Rahul1059 purchased last week.

vrd · May 31, 2009, 1:08pm

7k seems almost too good to be true for any of these PSUs.

according to Techtree:

i am guessing the price will be around 9-10k for the 750 and 11k+ for the 850

i absolutely agree with this. with the new PSU,coupled with the vx450, Corsair will monopolize the entry level PSU segment.

Rockfella · May 31, 2009, 1:25pm

I feel Corsair should come up with a 350-300W varient for HTPC and very basic PCs for around 2k. That wud be really good… or perhaps lower the price of CX400W.

tkin · May 31, 2009, 2:01pm

Looks like Corsair dropped the multiple 12v rails from most of the PSUs below 1000w range, both the TX and the new HX850/750 has only one rail.
