Multi Rail PSU.

Hello, sorry to bother you guys again, but I have a new question regarding my build. So I ended up getting a different PSU to the one I planned on getting, and it turns out the PSU is a multi rail instead of a single rail. From what I understand, Multi rails are sometimes underpowered for high-end GPU's, but I am wondering if you think it would be fine for something like a Radeon RX 6600?

Also, is there anything different I need to do when connecting the PSU to everything with a multi rail PSU?

Thanks

What specific PSU are you talking about anyways?

You got the model and make and some specs for us to help you with your question?

And yes the RX 6600 will probably be OK with 700 watts PSU. RX 6600 uses about 450 watts, depending on the maker and model.

Just a good guess, without knowing what it is we are actually talking about.

Sorry, the power supply I'm talking about is the Enermax Revolution D.F 2.  Although I'm confused about the wattage because in the title for the product it says 600W but in the PIC and the one that selected when you buy it shows 850W, so I'm not sure of the actual capacity.

It says from the Amazon blurb - ATX 3.0 and PCIe 5.0 complaint. But it is not - this is not an actual ATX 3.0 and PCIe 5.0, because all what is done is included a cable for two 8-pin connectors going to the new 12HPWR connector for the newest nvidia cards.

And falsely saying is allowing 600 watts for the new 12HPWR connection when maybe not. It is a 850 watt PSU maybe allowing up to 600 watts for the 12VHPWR connection (for Nvidia ATM although AMD and Intel may follow suit and also adopt the 12VHPWR connection in the next series of graphic cards too), but it is doubtful.   

OK if using something like a  6600 XT, then this PSU is overkill. 

And the single rail is critical if using a high end or upper tier graphic card. If not then it doesn't really have that much importance.

Sorry for the 700 watt comment in my previous post - I was brain fogged.

So is this PSU good anyways - not really that great. I couldn't find any details on the warranty period of this PSU even at their own web site, so I am guessing it is not good (maybe 3 year warranty). Better ones have 7 year and the best is 10 year warranties. 

Now questions - are you going to use a 6600 XT? If yes, then even a 550 or 600 watt PSU will suffice for this.

Are you  going to upgrade in the near future? Then go higher in wattage - a 750 watt PSU will be ideal (RTX 4070 uses 650 and a RX 7800 XT maybe a 700 watt for examples) so a 750 watt PSU will be OK if upgrading this high up.

Are you going to use a high end Nvidia card in the near future? Then get a PSU with a dedicated 12VHPWR port on the PSU for later on in the future.

Are you going with AMD and staying with AMD? Then don't worry about the 12VHPWR connection and just stay with the usual 8-pin PCIe connectors.

Are you planning on buying a PSU just once for this build and the next, or maybe a big upgrade in the next few years, then see below:

Oh about the rails - if using a 4080/4090/7900XTX, then go single rail. (think like 1000 watt and higher PSUs).

If not using these graphic cards, then don't be concerned about it.

A good PSU with the 12VHPWR connector (10 year warranty and is rated to be very good) and notice it has the actual 12VHPWR on the PSU body itself not some excuse of an added cable to flog out of date PSU as being the latest on unsuspecting consumers:

This is good too with a 10 year warranty plus it has 4 8-pin PCIe/CPU  connectors (meaning it can accommodate high end boards and a high end graphic card at the same time) and it has the dedicated 12VHPWR too.

All three are highly rated and very good. Did I mention these have 10 year warranties (plainly stated on their web sites too, not a hidden detail such as the Enermax does so we can't tell what the warranty period really is,  - what are they hiding?)

 

Wow, thank you for the detailed response. I don't have any plans to Upgrade the GPU and for now will just have the RX 6600 not 6600XT. I don't care if the PSU is overpowered since I already ordered it, just as long as the rail powering the GPU has enough power for the 6600. Not sure about the warranty but I thought Enermax was a decent brand PSU for a budget PC.

Have you actually got the PSU or is it yet to arrive.

Just a fyi, the Revolution D.F. 2 1050 is single rail, has a seven year warranty.and rated as for use with mid range computers, for the asking price you should be getting high range and a ten year warranty.
