Hello OCNers,

I have a severe case of search overload going on and I'm totally confused as to what PSU to get.

The PSU will be used to power my future rig which will get under way in the next month and here is what it will be powering:

3930K
R IV E
GTX 690 ( I might go with with 4 680 classifieds instead)
GTX 690
A max of 30 fans (3 480 rads in push pull)
2 MCP 35X pumps running dual loops
3 ~ 4 7200 RPM HDDs
2 SSDs
LED Strip for lighting (NZXT Hue)
Fan Controller
PCIE - Wifi card

What I have for a PSU right now X-1050, and I will say I'm very happy with it. It powers my existing rig (the monster rig in the sig) without any issues at all and the fan doesn't even come on under heavy load. Why I want to replace it is I hate sleeving this PSU, I could buy already sleeved cables but then its not as much fun (hate the double wires)

After reading a lot about single rail and multi rail, I now understand that I should look at a multi rail set up as that offers more protection at higher levels.

I was very close to buying a AX1200 but I did not as the last i ran the numbers to see how much PSU I need this is what came back:



I read more and then as of now my top choice is the ST1500 has everything that I want, followed by ZM 1350. I looked at a lot of others like Lepa but they use the same connector style as Seasonic 18+10 to 24 and I hate it.

I'm not concerned about the PSU length or the length of the cables as I will make my own. (I had a chance to meet with lutro0 and was able to learn some tricks that I did not know about in person) so I would prefer to have 2 things absolutely in the PSU

1. Fully Modular.
2. No Double wires on the 24 PIN.

I know it removes a lot of great choices out for me and silverstones are prolly the only ones that I can think off that meet my criteria.

Thanks for looking and for making your recommendations guys.

They're there for a reason, they're VSense wires and they are responsible for the excellent voltage regulation that your PSU displays.

1st. These days I don't really get sleeving, 10 years ago yeah.. when you had the rainbow snake nest from PCP or w/e.... these days though, sleeving is chessy and infantile (excuse the bluntness).

2nd. Your current unit should be perfectly capable of powering that system (with two 690s) and it is indeed a multi-rail unit (the single rail graphics and marketing material are just that... fake advertising for the purpose of catering to the ignorant consumer crowd).

I read that from your previous post regarding the x-1250 being a multi rail. Sorry to ask, but you mentioned that there is a way to connect things to this PSU in a way that you can get the benefits of the multi rail, is there a document somewhere for that?

Thanks for your input mate.

I guess I can just spend the money on new longer cables then getting a new PSU.

I trust your knowledge when it comes to PSUs so I have no issues sticking with what I have as like I said before I do love this unit.

I should go back to the reason why I got this guy in the first place, Function over Form.

Check Wolf's review of the XFX Black Edition 1250W Gold @ JonnyGURU, he has a table there for the connector/rail arrangement (incomplete though).

As for the new PSU, if you do decide to change it with something bigger... I'd suggest waiting a little bit longer for what's about to come on the market pretty soon... the Antec HCP 1300, BeQuiet! P10 1200 (they should be available in NA in March, and it's the best implementation of the X-1250 platform from Seasonic), or even the new NZXT Hale90 V2 1200 (wait for some more relevant reviews first.. JG, TPU, [H]).

Perfect, you sir have answered all my questions and put my mind at ease. Now there is only 1 questions left, how do I thank you since there is no option to give you rep?

You already did, buy understanding what I'm saying and not making me repeat myself needlessly and to no avail (as in the case of Stu-Crossfire)... in a sort of weird soliloquy.

Glad, I was not a disappointment. I think I will stick with seasonic for now and in the future. I love NZXT products but cant say the same about their support. Don't ask me why I hope someday EVGA will deliver a PSU worthy of carrying the EVGA name.

Power estimators tend to exaggerate power needs, and XbitLabs found that very few computers consumed over 600W:

http://www.xbitlabs.com/articles/cases/display/system-wattage.html



The easiest way to get a good estimate of your power needs is by running a worst-case test that loads down the CPU and graphics while the computer is plugged into a Kill-A-Watt, and multiply the Kill-A-Watt rating by 0.8. A high quality PSU rated 30% more than that will be fine.
