We're not going to see a 500w PicoPSU any time soon.
The max I would expect from a PicoPSU is 250w, and that's really pushing it.

Mini ITX is also not a PSU Form-factor. Though sometimes FlexATX PSU's are marked as MiniITX. (That's a good unit BTW)

The reason people do not get into that market is 2 fold:
1.) It's a niche market
2.) It's costly to develop small, efficient, and marketable PSU's. People always think they need a 600w PSU for a x2 555BE & HD6850

Greetings.

I plan to go SLI GTX 580's soon.

1) Will the Silverstone DA750 be able to handle the Sig Rig plus the 2nd GTX 580?

CPU is currently @ 4.5

I also have a Silverstone Zeus (1200W), but I wanted to wait until I sleeve all the cables.

2) Should I just be a little more patient and wait until the Zeus is ready for action?

Thank you for your time.




P.S. Happy Friday!

I assume this is the fully Modular Zues 1200w unit?
If so, be patient and use it.

The DA750 will buckle under the load of that system. Most definitely in a F@H scenario.

When will Single rail be optimum and Multiple-rail be optimum?

I see some PSUs like Mushkin Volta's having an option to switch between single/multiple rail operation.

In a perfect world, multiple rails are optimum; though to be frank it doesn't matter much.

In some cases OCP (what they used to divide a single 12v source, up into virtual rails) can save your PSU and whatever is connected to it from having melted pins and such; it still isn't often.

The cable that benefits the most from OCP limits is actually the ATX 24pin cable; as some folks will use 3-4 high end GPU's on a motherboard, each demanding 75w from the PCIe socket; without plugging in the PCI_AUX connector (usually a 4pin molex, but some boards use a PCIe 6pin) to help distribute the load.
Thus resulting in a melted ATX 24pin connector as to much current is flowing through it, causing the pin to heat up and a failure to occur.

If you were looking at two equally equipped PSU's and the only difference between them what one had multiple 12v rails and one had a single 12v rail; your best option would be to go for the Multiple 12v rail unit.

Will my 850 watt Diablotek PSU run SLI GTX580s and a OC'ed 1100T? J/K

Is it possible for PSU makers to add a consumption/load monitoring part on the PSU that can connect to the mobo via an un-used USB header? Basically like a built in kill-a-watt.

One company did recently, I don't remember who. HardwareSecrets reviewed the unit. Let me find it.

How much will a little bit of current traveling up a +5V rail (or any other +voltage) hurt a PSU, or do they protect against that?

Also, a friend just gave me a 900W rosewill. Should I be worried about it messing up and frying some of my components?

Pretty much all psus have a 5v rail, hard drives for example use the 5v. If you can pull up the model name of the rosewill that will help a little more.
