The ability to disable the C6/C7 state should be in the power management section of your BIOS.

But your problem is not Haswell sleep state related because your computer wasn't asleep or going in or out of sleep.

If you think your power supply has an issue that's causing these shut downs, I suggest starting a new thread. But since it's not Haswell related (except for the fact that you happen to have a Haswell CPU), we shouldn't be discussing it here.

The Haswell Compatibility List doesn't seem to have been updated for a while.

Is the CX5000M PSU 100% Compatible with Haswell CPUs, and for that matter, are any of the low wattage PSU's?

It has been updated recently. That's why it includes RM and CS-M. ;)

The units that are listed as "100% compatible" are stated as such because they all pass the testing for Haswell laid out in the latest Intel PSU design guide. The one's that are listed as "likely" do not pass the synthetic tests in the DG. This is why those units have not been updated.

Internally, we cannot always duplicate the results of the synthetic tests with real world PC's. And even if we can, we can eliminate problems by disabling the C7 sleep state in the BIOS. But, to be "fair" to Intel and compliant with their PSU-DG, we can't make a blanked "it'll work" statement if a unit does not pass the synthetic tests.

Is the CX500 "100% Haswell Compatible"? According to the Intel PSU-DG: "No." Will it work with a Haswell based PC? Likely, yes. Are there low wattage units that are 100% Haswell compatible? Yes. The CS-M Series.

I meant updated with Haswell information. The list was posted 9 May '13 and hasn't been updated since then as far as I could tell.

The term "Likely compatible — currently validating" gives the impression that testing is still happening. Hence my perfectly natural question.

If the issue is finalised, as your repsonse suggests, the better terminology to use on the list would be, "Likely compatible but doesn't pass synthetic tests in Intel DG. Solution: disable C7".

Anyway, the relevant question is which PSU to get for a performance HTPC (as below) where sleep (preferably as intended) will be a very important function.
i5-4570
H87M
2x4GB 1600
Intel SSD
2 x 3TB Seagate 7200rpm
... and possibly a GT640 or a HD7750 (depending on how the Intel HD4600 picture quality looks)

Would the CX5000M be appropriate or the CX430 v3 or would I be better off getting an RM450?

Thanks

CS450M is not a consideration?

The CS450M is not available in Australia. Also, even though it's moot, it doesn't seem to have had many reviews on Newegg.

Over here, the Corsair options are basically the VS, CXv3, GSv2, TX, HX, RM & AX.

So firstly, do you think 430W or 500W is about the right wattage for that system and secondly, would the CX5000M be appropriate or the CX430 v3 or would I be better off getting an RM450?

That's because the CS-M was just released a couple weeks ago. It should be at Altech soon. In fact, I'm surprised it's not there now.

But you have a pretty low wattage system there, so even a CX430 should work.

Altech don't have it listed yet and the one user review on Newegg was pretty average - but more importantly, I need this PSU now.

I prefer to err on the side of having more than ample power rather than being "just right".

So do you think 430W or 500W is better for that system and secondly, would the CX5000M be appropriate or the CX430 v3 or would I be better off getting an RM450?

RM450 is more efficient and you can measure your +12V power consumption with Link, so naturally I'm going to suggest the RM. ;)

Just a quick question I've already asked and nobody answered:

How do you know if your HX-650W Corsair PSU is bronze, silver or gold version? I am currently looking at one but I don't know how to check its version. Is there any way to know if it's bronze, silver or gold?

The code model is CMPSU-650HX, but I googlling that I found bronze, silver and gold HX650W Corsair PSU's with that model number, so how can I know which one is that particular PSU?

Thanks

There's more to the part number than that. Where are you "looking at one"? At a store? Online? eBay?

HX650 (CMPSU-650HX) - Bronze
HX650 (CP-9020030-NA) - Gold

Don't recall a silver model.

FWIW, my AX760 is working beautifully with my i7-4770K and EVGA 760 4GB.

Fixes I've found:

Disabling the C6/C7 states - didn't work for me
Disabling the C1E state - reduced the failed power ups from sleep by 90%
Adding an extra system fan directly connected to the PSU - will try this next
