Upgrading build - PSU still okay?

[syrup]

As title states, looking to upgrade (essentially rebuild) my computer. Does my current PSU still work? It's a SeaSonic M​12II 620 B​ronze 620W that I got 3-4 years back.

Build is going to feature a i5-6500 and a possibly a 1060/1070 single GPU. No RAM OC either.

If I should be replacing the PSU, what's some popular picks these days?

The S12 is a superb PSU... 620 watts is more than enough for a 1070 which requires only a 500 watt PSU.

Just so you are aware, if you buy a set of RAM that says 2400 on the package / advertisement, then what it 'says on the package" is generally the XMP profile which is, by definition, overclocked. This guy bought some 1866 RAM for his system.... it has an XMP profile for 1866. The 1600 JEDEC profile is what the system us rated for under the JEDEC standard applicable to that RAM at that time. He is using the XMP or overclocked profile.

I'd have liked to find something more current, but if you see anything advertised at a certain speed, it's likely going to be XMP profile. IIRC, JEDEC now goes up to 2133 (haven't read in ages) so anything higher than that is, by definition overclocked. That does not mean it is in any way unsupported by Intel

I'd say 95+% of peeps out there are running under XMP profiles.

Yes, the PSU is still okay.
It is a very high quality unit, and will be perfectly fine for a new rig. The S12II and M12II are still frequently recommended today!
What is your budget?
I can put together a list for you.

Technically.. its a M12? I know the S12 is a popular recommendation. Unless I missed something?

 

[Chugalug_]

The M12II is just the same PSU with modular cables.

 

[JackNaylorPE]

Oops... the M12 is the modular version of the S12, both ... I just didn't have a reference for the M12 in this size range ... and I forgot the link anyway :

http://www.jonnyguru.com/modules.php?name=NDReviews&op=Story5&reid=185

Both are built on the Seasonic GB Bronze platform which includes:

Antec High Current Gamer (M) 400-620
XFX Core 450-550
XFX TS 550 Bronze
Seasonic S12II Bronze
Seasonic M12II Bronze 520-620

I seem to get a lot of people complaining that the S12II is not 'Haswell Ready' while the M12II is, but it is the more or less the same unit no? I don't see why one would be any different from the other.

Interesting. Well, I guess I was referring to tweaking the RAM settings instead of using factory(?) default. In any case, since you mentioned it, I'll likely go with: http://pcpartpicker.com/product/4vWrxr/gskill-memory-f42400c15d16gvr

Should be fine right?

 

[Chugalug_]

Yep, should be perfectly fine.
What he means is that often people buy high frequency RAM, and forget to or don't know how to change the XMP profile setting to match their RAM's rated speed.
Go into DRAM settings, XMP profile and set it to 2400MHz, you'll need a Z170 board to do this, but if you're not overclocking, it should be fine running at the native 2133MHz on a H170 board or lower.

Oh, so the 2400MHz RAM I linked is factory defaulted @ 2133MHz, but has another XMP profile that OC's it to the advertised 2400MHz. If I just stick the sticks in without adjusting for this, it'll naturally run at 2133MHz unless I switch it to 2400Mhz XMP profile?

 

[Chugalug_]

Correct.

 

[Tradesman1]

If you run it at 2133, check what the BIOS set's the timings to, they often will go to high loose JEDEC timings rather than try to optimize them. The RJ V is a CL15 set so for 2133 will run CL14

The M12ii does not support the Haswell sleep states. In this case "Haswell ready" just means "works with a Haswell processor". You see this all the time, it's trickery of marketing. No group regulated design can be Haswell sleep state compatible.

I imagine it's like anything else ... send it somewhere, pay a fee, and you will get a certificate saying what you want. Some folks reputation is such that they don't figure it's worth it.

The 2 most frequent RAM questions I see on the boards are:

1. Why does my RAM speed in CPUz say only half what is supposed to be ? Double Data rate, the D for double means multiply CPUz x 2

2. Why does my 2400 RAM only run at 2133 (1067 x 2) ? Caise you are running JEDEC rather than XMP.

The RAM has an SPD
https://en.wikipedia.org/wiki/Serial_presence_detect

When you finish, the BIOS will default to highest JEDEC setting that it sees on the SPD. This pisses lotta peeps off as they wonder why the package says 2400 and thge highest non-overclocked is only 2133. Your XMP profile may be higher than 2400... you may have multiple XMP profiles. The point is, if you are going to use it, they want you making ba conscious decision to enable anything higher than is started in the JEDEC specification. it's really no bigga deal, open BIOS, enable XMP, save and exit.

This is a little outta date but shud give ya the jist of it.

With DDR4, the BIOS will default to 2133 on initial installation - not the highest JEDEC setting as there are standards for 2400 from JEDEC and some sticks will have those in the SPD. With DDR4 XMP applies to DRAM above 2133, (similar to DDR3 where it only applied to DRAM 1600 and up). Also the SPD has 2 XMP profiles available in the SPD (not multiple XMP profiles). Many read Intels description of XMP and misinterupt what they are saying when they talk about the SPD having'multiple' profiles, the bulk allowed are for a variety of JEDEC spec profiles
