Cheap PSU experience and question about connections more PSU

[KaydenC]

You could also check out parallelminer.com, they have all the gear you need to setup a mining rig, including 1200 watt platinum rated server power supplies etc. I've bought from them 3 times now and have had reasonable satisfaction with them so far.

Like this psu? http://www.parallelminer.com/product/2400-watt-power-supply-kit-for-gpu-mining-94-efficiency-200-240v-ethereum-eth-zec-dash/

Where did you find pico psus for them?

No that is a 240v only setup. The one I was referring to is this:

You can also buy an open frame case with the powered risers, PSU etc already installed from them if you wish.

Those server psu's look nice for some big setups.

But it looks like you still need a consumer psu to power the mobo, hdd etc.

So in the server world how do they power up the mobos?

[bel123]

so the best way is to use server psu for graphic cards and second psu for processor, ssd etc?

Anybody use HP psu like this or this - such PSU really has more then 90% efficienty?

What i need for such configuration to work everything as safe as possible?

- add2psu? Is this (1) or this (2) ok?
- breakout board for hp like for example this
- Corsair CS650M for second (not graphic cards) will be ok or 650 Watts = too many? (not optimal work then) I can buy cheap such psu.

Those Add2PSU links look like cheap knock off's. The original is http://www.add2psu.com/.

I would suggest getting the original. You do NOT want to cheap out when it comes to supplying power to your GPU's.

Do you really know or think that this oryginal is not the same like from alibaba or aliexpress? Many products people take from ali and sell in US with 2 or 3x price.


ps. i found HP Hewlett Packard Enterprise 499243-B21 2400 Watt - anybody saw it, is it better then delta 2400? (delta has 3 fans, this i do not know but maybe less and because of it will take less watts for cooling?)

Do not buy cheap PSU always go for @least Gold 80+ unless you get free electricity.

It will pay for itself in 1 year.

For example: I had a 1000 watt no name brand not rated PSU that was pulling 750 watts for 4 RX 470 gpu rig. I upgraded to 1000 watt EVGA 80+ gold for $139.99 which is pulling 600 watt for same rig saying me 150 watt i pay around .11 cents for electricity.

so (.150 x 0.11 x 24 hours x 365day) = $144.50 in just 1 year. Plus more stable less heat and less voltage fluctuations.

Again don't cheap out on PSU

That is right. That is why I changed most of my gold PSU to plat PSU now.

I'd be willing to bet that Delta PSU in the link is insanely noisy.  Delta fans are amongst the loudest, and a bunch of tiny ones like that will sound like a herd of pissed off dentists coming to get you...

Yeah, even the 1200 watt HP one with just 1 small fan is a very unpleasant high pitched buzz. I won't use them in living space due to the type of noise... 1300 watt EVGA SuperNova works well for my needs.
