Juan,

Looking at the pictures of your case with ventilation on all sides I would think the Seasonic supply will get on fine in there. Mine is at the bottom of the case with no fans in the entire  pc and is fine for heat.

Cheers,

Nick

Paul,

I could not agree more ! and I cannot wait to hear your new speakers next trip down. Thanks again for lugging all of you fine kit to mine. Its so useful having known reference points to work with.

Best,

Nick.

Peter,

I can see how that could work haha. Alas the helicopter is not mine  it just dropped into our paddock on a visit a while ago.

The boatcopter may have to go untried 

Diede,

Love your GTR must be fun on a track 

Nick.

That's a nice view at your place Peter, no lakes here that I'v noticed 

Thinking I want to be a little more structured I found this link which is a good explanation of how digi+ parameters work. There definitely is an ability to change sq with these but its important to try to figure out what helps and what harms sq.

Hey Brian,

I just Googled Adirondak, I would not be rushing home too fast, looks really beautiful. I worked a little in New York a while back and never knew where to head on the rare occation that I got a little time to myself. Now I know 

Regards,

Nick.

Hi guys,

This is what I plugged in. There is not much science at work other than trying stuff out and trying to stop the digi+ feature from doing its own thing on the fly. It did work well here, maybe a little forward in places but I am using some interconnects that are quite forward so a change should  address that.

Could be lots to try and understand. See what you think.

Regards.

Nick.

Arnt,

Very pleased to here that it has worked well. I was a bit concerned that people would give the change a try only to find it was my particular ax750 which was not working. Evidence could be mounting that  as the seasonic may just be better for music.

Regards
Nick.

Helepicoptors are fine here 

Hi,

I'v been playing with declocking for a while since Peter mentioned this a mothe or two ago. Now that the ATx supply problem is fixed I can easily hear the differences of settings.

Rather than adjusting the CPU clock frequency down, I have been lowing the clock multiplier in bios. Standard setting on my PC is 32x giving 3.2ghz cpu frequency, lowering it to 24 improved dynamics detail level and blackness it can go as low as 12 but I'm sat listening to 18 and on my PC, this appears to be a sweet spot. Very nice.

Nick.

Juan hi,

The main reason was that it was way was in Paul's PC and I was keen to use exactly the same. I put a mains power tester on the PC (3037 CPU) and found that it only uses about 120 watts whilst playing music at normal CPU clock speed so that checked out ok.

The reviews on line of the 400 460 and 520 versions show the larger versions making just a small amount more ripple noise but not sure that this was a problem so I went for the 400w version in the end.

Brian is switching out a corsair ax750 for a seasonic I think so his experience may help understand if my corsair was just a poor unit or if the seasonic is generally a good upgrade.

Cheers,

Nick.

I was getting round to looking at noise levels on my DAC outputs and I2S lines this morning with the new Seasonic ATx supply fitted and decided to look at something that has been on the 'to do' list for a while.

More recent ASUS mobos have something called Digi+ Power Control options. This seems to be a chip which can "tune" voltages and currents and mobo power phases to main components on these mobos.

I'm not much of a fan of these things as you could have all sorts of nonsense happening to power on the mobo on the fly at speeds that effect music. So I went into the 15 or so bios parameters and started removing "auto" settings and replacing with basic settings to reduce in flight tuning of voltages.

I'v ended up with quite a difference in SQ, [very] good it think. Just listening to Sash! now and the synths are like never before with an exciting and pure top end. These tracks have always been a system test for me because the highs usually make the system desolve into producing a "tish tish tish" version of what is happening in high hats, cymbals etc.  Now is riveting 

It would be very interesting if anyone with Digi+ features on their mobo wants to give this a go. Happy to post some starter settings.

Regards,

Nick

Brian hi,

Your description of sound with and woithout the PCIe X-Sound card is very similar to what I was finding, the ATx replacement coule be a good direction to try. I hope the Seasonic works for you as well.

Best Nick.

Ps I keeping meaning to post the location of SpeedStep and C1E settings in our BIOS for you after you question in the C1E thread. Do you still need to know where they are ?

Naturally, the only correct car choice for the journey 

Going on the reviews the 460FL seems to have the ~same noise performance as the 400w version give or take a mv of ripple or so. I can see why your satisfied with them.

Going Linear would be very interesting. I put a Watt meter on the mains lead to the Asus P9x79 PC. Running at normal CPU clock speed it consumes about 125 watts at idle and running XX it is the same so it should be possible to achieve linear supply even with a "fast" PC.

Have you see these ?

It would easily deal with 125 watt draw. ItemAudio are reselling in the UK IIRC.
