How much power does Aurora R4 MIO board need? Safe to daisy chain?

Hi fellow Aliens,

I have a question. How much power does Aurora R4 MIO board consume? It feeds through a 4 pin MOLEX.

I plan to daisy chain two SSDs, one HDD, one optical drive and the MIO board together to save power.

PSU: Corsair RM 750X in Alienware Aurora R4 chassis.

Thanks

save power? how?

Some of those, 4 of those will run off of SATA power, right? Is your plan a SATA -to= Molex adaptor?

x2 Molex 4pin cables in the pouch + x3 SATA cables > normally, you'd run x1 Molex to MIO, then power the rest with the SATA cables, why isn't that an option. is it a cable mngmnt issue?

Running all items off of one cable won't 'save' power, it will if anything heat the cable up, lol. The idea is to have as few items on a cable as possible, fewer the better, can you try that? MIO might consume 3amps / 36watts

No, I do not plan to save power.

I am wondering if doing so may cause current overload and burn cable.

I have a SATA to molex adaptor. The cables are corsair made except the SATA to Molex.

1 peripheral cable serves two SSDs, a HDD, MIO and the Optical drive. Would this be a problem?

I know that SSDs consume negligible power. Optical drives are rarely used. HDDs may only consume 5 Watts. How about MIO?

You don't want to use or clutter up the inside with all those extra heads right?

See video for how to back the pins out > back the pin out of the head you want to keep, then 'break the wire off' (twist it forcefully, wiggle it back and forth til it snaps off) of the head or daisy chain you want to lose. Got it? Break off the part of the chain you don't want if this is what this is all about

should be 450mm ~18inches to 1st Molex head. If the 1st one reaches MIO, break the other three off > if the 2nd head reaches, break the other two off, undertand? Then push the pins back in

Tip: Break the heads off of the one you have there & buy a new one to replace it, or, if you don't want to ruin your new cable (& plan to use your adapter for now ) buy a new cable & when it gets there break the heads off you don't need or want

1.4amps for the rad-fan, call it .75amp for pump motor, whatever your PCI HDD mini-Roof fans are, then case light LEDs, 3-4amps, 36watt-48watt? Check your fans and see, or, find your fans on eBay and read the back label from a photo, I don't have the figure, 'nobody does'

adapter rated for 4.5amps 54watts see chart

this is better than the adapter

How do you still remember that I have fans on my aurora roof?

Hello Cass, All your words make sense.

 

Let's condense them into points:

 

1. I gotta be careful with SATA power cables as the Orange wire is often missing. The orange wires allows SATA power to deliver around 14.85 Watts. Yet aren't these orange wires obsolete?

 

2. The MIO actually consumes a significant amount of power as it commands fans and LEDs. I do not have a liquid cooler though, I use a tower cooler. Am I correct?

 

MIO Power load; assume fans operate at maximum power:

 

- LEDs: unknown power

   - 2 X Noctua NF B9 Redux: 2 X 0.96 W = 1.92 W

   - 3 X Noctua NF R8 Redux = 3 X 0.72 = 2.16 W

- Fans = 4.08 Watts

 

As I do not have a liquid cooler, I project to need around 12.5 Watts in total (Fans + LEDs + the MIO itself).

 

3. Instead of creating a cable monster, you suggest me to remove the unwanted heads from Corsair's wire. I can then mend the severed connectors. The reason I do not buy a new one is because even the new ones come with too many connectors I do not need. Am I correct?

 

4. I actually avoid modding cables as I may cause unnecessary human errors.

 

5. I see a contradiction of the cables. Standard 4 Pin molex lacks orange wires. SATA power at playtool.com has the orange wires, but mine do not. Corsair molex cables lack ones too. Even an Corsair official SATA cable lacks orange wires: Premium Individually Sleeved Peripheral Cable, Type 4 (Generation 3) - Red/Black (I have this one).

 

7. For every half meter of Molex cable, you lose 3.3 Watts according to Playtool.com

 

8. According to Playtool like you sent me (All about the various PC power supply cables and connectors), normal molex allows 85 Watts per connector. A normal SATA allows without orange cable allows: 54.5 + 22 = 76.5 Watts. My cable plan:

 

  • SATA power 1: Goes to HDD
  • SATA power 2: Goes to SSD
  • SATA power 3: Goes to SSD
  • SATA power 4: The problem kid

 

I plan to split SATA power 4 to MIO board and optical drive. Each SATA wire can handle 4.5 A according to Playtool.com while 4 pin Molex wire handles 5 A each.

 

Since I only have a SATA power output, I have a SATA-to-Two molex adpater. One Molex goes to MIO, the other connects to a Molex-to-SATA and connect to optical drive.

 

Thoughts?

I didn't 'member, you never gave an update or posted a pic. I meant plural, HDD PCI + rinky-dink top 'fans', the three of them. If it's plugged into MIO or top light strip, it's part of the total. I didn't have time to use eBay Google for original case fan specs based off of rear label pics, but yeah, if you look for them yourself you can guesstimate wattage. So what did you go with in the roof, & was the install easy moderate or hard to get them up there

Hello Cass,

I have another reply that is still waiting for a moderator.

I guess the moderators haven’t confirmed my reply.

Here’s a quick reply. I have a Corsair RM 750X and I plan to power several devices.

I am going to use CP-8920186 SATA cable made by Corsair.

There are four SATA power connectors on this cable.

#1 Goes to a Seagate 2 TB HDD ST2000DM006

#2 Goes to a 512 GB Crucial MX300

#3 Goes to a 512 GB Crucial MX300

#4 is the problem kid

I plan to split number four two power:

- ASUS DVD writer 24F1ST

- Alienware Aurora R4 Master control board

The Aurora Board powers five Noctua Fans (2 X 0.96 + 3 X 0.72), the board itself and AlienFX LED (maybe around 10 Watts).

Am I going to burn my cables? Do I put too many devices? SSDs consume negligible power and DVD drive is comparable to HDD.

seems to me you would split the SSDs #2 #3 instead. What's wrong with the Molex 4pin cable that you seem bent on not using it?

I don’t think it is far enough to reach the MIO board. But I should consider cutting it.

Plus I can simplify cable management as a single sleeved cable from corsair can handle nearly everything.

You’re saying split a connector to power SSD 2 and 3. Am I correct?

In my experience and skills, Aurora R4 doesn’t work very well with ribbon cables.

The original is 20", I just measured it. New one's supposed to be 450mm to head #1 which is almost 18inches.You'd have to break off heads 3 & 4, use #2 most likely, since 450+100mm is about 22"

You don't cut it off. When you back the pin out, two wires are jumped to it. The wire you want to discard, aggressively shake, shimmy, twist, whirl it around in circles, flip it & flop it til it snaps off the pin for you, normally it's a clean break > reset the metal pin tabs, pop pin back into connector and its insulated. If you have nose hair clippers or precision scissors, needle nose pliers, if it isn't a clean break you can still clip it or snip it, any traces of baby wire left behind. For that matter you take a screw driver tip (lift the insulation up) & push the traces back into the pin, under the wire you kept, you'll figure it out

My main SATA is a ribbon, tucks in ok under the clamps & up into the snap-lok > Mio goes through sleeved, I took a ribbon, pulled it apart into 4 wires & sleeved it

You said this > I plan to split number four two power:

- ASUS DVD writer 24F1ST

- Alienware Aurora R4 Master control board

You'd want MIO on it's own SATA head, not 'split' with some other device, since it will have the highest power needs. If you want to 'split' something, make it low power. Connections are a source of resistance, resistance = heat, resistance = loss of amps

Do u have ALX with rear SATA hard drive power connectors? Or non-ALX with the front ez SATA connectors? Because your new front panel has x4 SATA 6pin ports, I'm not sure why you can't use them as > Main SATA gets a ribbon > each hard drive bay gets a ribbon > MIO gets a Molex

If the SATA's are too many heads, you can cut those off too, I mean it, lol

Sequence is to remove the cap 1st, cut all 5 wires flush, transfer the end cap on to insulate it. Buy a replacement cable to mod or to replace the one you modded there

Front SATA. I’ll guess I’ll play it safe. I somehow was able to convince amazon to let me return the SATA power cable.

Cass, I now plan to divide power with the much safer and less wire-y Molex cable. Thoughts?

Glad to know that. I hope I’ll be able to simplify my cabling.
