So with 230V and one Neptune cube - clock 475MHz
Corsair RM1000 - 415W only (including control unit) - absolutely quiet - fan is no rotating
DPS-800GBA - 446W (and it is without contr. unit) - quiet, but not as RM1000

it seems that DPS-800GBA is about two class lower... I can recommend it for low price only and for people with cheap electricity

And for Corsair RM1000 is not necessary to buy adapter/cables - it has PCI-E AWG16

If you are willing to fork over the cash for an RM1000 which is only Gold rated and costs $167 on Amazon you should check out our 1200 Watt Platinum kit. It's an Intel DPS-1200TB PSU that is 80Plus platinum rated and is $147 including shipping. So you are getting a more efficient better quality PSU for $20 bucks less. We also offer volume discounts starting at 3 units so if you are buying multiple you save even more.

are you doing 240 volts? or are you doing 120 volts?

all my testing was 120 volts.

if you are supplying 240 volts.

try testing both the units with one cube.

what you may have discovered is the hp does not ramp up well with the 240 volts.

if you do both with 240 volts and do both with only 1 cube.

I would like to know the results.

my guess would be that the dps-800gba will do a lot better with the one cube not 906/2 = 453 it will be quieter

I would think it will be more like 440 or 435 watts.

and the rm1000 will do closer to 846/2 = 423

How easy is this to set up for someone whos new to this? Is it something that someone with limited electronic knowledge would be able to do without a problem? or am i SOL?

It's really dead simple. Zero special knowledge is required and all you need is a standard screw driver for attaching the wires to the board. Really isn't substantially different than buy a standard ATX PSU except it is a lot better value.

I can not recommend this HP PSU, maybe only for very low price, efficiency is only a little better than 80+ bronze.

Yes, we agree the DPS-800GBA is on par with a 80Plus Bronze.

The hp-800gba I tested ran really well up to 700 watts on 120 volts.

It would be good to know that the 120 volt rating does not really jump to
much when you go to 240 volts.

I know I got very good at 700 watts and 120 volts. much much better then the dell did at 700 watts.

I have one PSU DPS-800GBA with adapter and yesterday I was testing it with 2 KNC Neptune cubes.
Power efficiency in comparision with ATX Corsair RM1000 (80+ gold) is very bad.

For example (from the wall):
RM1000 - 2 Neptune cubes 475MHz with control unit - 846W only (and very quiet)
DPS-800GBA - 2 Neptune cubes 475MHz w/o control unit - 906W (and loud)

I can not recommend this HP PSU, maybe only for very low price, efficiency is only a little better than 80+ bronze.

You and I disagree. I will point out you are testing past it limits.

It is an 850 watt device. run 1 cube with it .. price is 55 bucks and a rm1000 is about 130 to 160 usd.

If you run 1 cube with it it will be quiet and do better watts.

if you ran the rm850 with 2 cubes it would be a more fair efficiency test.

both the rm850 and the hp dps-800 would be close to max.

comparing it to the rm1000 which has a lot of overhead is not a true comparsion.

or run both the rm1000 and the server hps-800 with 1 cube.

running an 800 watt piece of gear beyond it rating won't tell much about efficiency .

No it is not true. DPS-800GBA and RM1000 have THE SAME power (230V). 12V rail both aprox. 83A

Just placed an order for 10 of the Plat kits. Pete was very helpful answering questions.

Thanks for your order! Just shipped these out this morning. Check your email for tracking #.

The plat is really good for running a sp20 at 1300gh.

It is lean and thin it stacks right on the sp20 it does about 725 watts at a kwatt meter running the sp20 at about 1300gh

This was all with 120 volt power source.
If he has 240 volt it will drop a bit.
It will give him a compact foot print.
It will run pretty quiet pulling the 720-730 watts.

It also gives him a lot of overhead he can push the sp20 if he has low power cost.

with that discount they become a good deal. I really liked the plat best. (a little pricey if you get 1) but 20% off for 10 or more helps a lot.

are you going to use 240 volts or 120 volts? All my tests were for 120 volts.

As much as I hate to endorse the competition, I'm out of stock for 750W stuff for a couple weeks (we had an unexpected run on materials) so... buy this guy's instead I guess.
