Kingwin LZ-1000 vs Corsair HX850?

Hey there everyone, just found the KINGWIN Lazer LZ-1000 PSU on sale for a grand total of $160 on Newegg (Canada).

I was wondering if anyone had any thoughts on this PSU, as it is almost $35 cheaper ($25 after MIR) than the Corsair HX850 that I was planning to purchase.

So I'm basically wondering what people think of the LZ-1000 in comparison to the HX850.

Build components:
i5 2500k (overclocking in the future)
CrossFire 6970's
HDD and SSD
HAF 932 (3 240mm, 1 140mm fans)
Soundcard
2 sticks of DDR3 memory
CPU cooler (once I begin overclocking)

Any opinions on the LZ-1000 or opinions are, as always, greatly appreciated!

I'd buy the Corsair PSU.

By the way, overclocking an i5-SB will not add more than about 25 watts to the load on the PSU.

For a system using two Radeon HD 6970 graphics cards in 2-way CrossFireX mode AMD specifies a minimum of an 800 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 63 Amps or greater and have at least two 6-pin and two 8-pin PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT a crucial factor in power supply selection!!! Total Continuous Amperage Available on the +12V Rail(s) is the most important.

My vote is for the Corsair Professional Series HX850W. Its 7 year warranty attests to its quality. JonnyGURU.com gave it a perfect 10 for its electrical performance.

JonnyGURU.com said that the Kingwin Lazer 1000W can't even reach 80 PLUS BRONZE efficiency during their test review. This power supply only has a 3 year warranty.

i5-2500K Power Consumption from the +12 Volt rails @ 100% CPU load :
@ 5.0 GHz 224 Watts (18.67 Amps)
@ 4.7 GHz 134.9 Watts (11.2 Amps)
@ 4.3 GHz 99.7 Watts ( 8.3 Amps)
@ 3.3 GHz 75 Watts ( 6.25 Amps) <--- Reference Clock Speed

You're definitely wrong on that count.

JonnyGURU.com is the most trusted power supply test review site. They have the actual test equipment and test data to back up what they review.

Your statement that "The kingwin 1000 watt lazer is stamped 80 plus bronze so id go with that" is just your opinion with no data to back it up.

Why would I trust your opinion over JonnyGURU.com's (or any other reputable test review sites for that matter)?

Well i took my time and check out your Jonny Guru it seen the site is based on one mans opinion and if you care to believe in what he says so be it....But which Kingwin are you looking at myself im talking about the Kingwin lazer Gold read up on it if your in doubt Try looking at the kingwin 1220 Mach 1 which is around $ 180 like i said iv had kingwings sence 1992 & thats 7 builds without any power supply issues...

There's more than one power supply reviewer at JonnyGURU.com so your statement "the site is based on one mans opinion" is full of it.

The OP specifically mentioned the KINGWIN Lazer LZ-1000 PSU and not the Kingwin lazer Gold that you are harping on.

Jonnyguru are hardware secrets are the two main reputable PSU review sites, if you have the opinion that its just one man's opinion then i guess you don't trust any reviews on Tom's or Anand or anywhere else.


Also, care to make it more than one man's opinion? How about the opinion of 8 different reviewers?

All of them give it recommendations.


The Kingwin lazer, while still a good unit is a lesser unit compared to the quality of the HX850. The super flower platform does well, but there are many better, many of their more recent platforms like that used in the Kingwin Lazer Gold does much better. The Kingwin has not been reviewed as much, but you can do a comparison of the reviews on jonnyguru, you will find that jonny and oklahoma wolf both rely on the numbers they get from their testing not personal opinion like you believe.

Anecdotal evidence of "I said iv had kingwings sence 1992 & thats 7 builds without any power supply issues..." tells us that you haven't gotten any crappy unit but says nothing about their true capabilities or build quality, thats what reviews are for because the average user is not qualified to review a PSU.


So the next time you want to call a review simply one man opinions, get ready to bring some facts to back yourself up.

Not qualified theres one big difference between you and i...While your still looking and cant make up your mind im allready built...How hard is it to pick out a power supply id be embarrassed to have to ask...After the psu are you going to ask about the rest of the parts if thats unstable i dont know what is..
