We have been offering a short cable kit for our modular PSUs since 2006 and we still offer one now!

Actually, major brands do that, except Seasonic (unfortunately). In adition to the statement above, you can buy separate cables for Enermax, you can email to Corsair and they are sending you new cables for free etc etc. Of course there are probably some other manufacturers who don't provide replacement cables too, but if you have a fully modular supply, a full modular cable set bundled to it - what is stopping Seasonic from selling the same cable set in separate package ?

All it would take it for now is to sell the nice package on right as a separate accessory :) :

People will mod the cables if needed - but right now the only options for SFF user with Seasonic PSU are either cut the original cables and risk destroying them (=RMA), or to leave cables with the original length.

Btw Seasonic Rep, could you provide the Molex Mini-Fit Jr. connector P/N's used for the modular connectors ? That would be also helpful if someone would like to make their own cables (for example single sleeved, short cables).

They're Mini-Fit Jrs. You simply pick the appropriate size for your cable. It's probably best to match the coating, but not all that important for power, and I'd not be surprised if the coating varies by what they have available.

Well, that is all fine Monkeh16. Now head to the Molex website and find the correct part numbers with correct pins and lock pins. Good luck with that, i tried few times, but Molex product descriptions are one big mess, and for someone like me it is impossible to decode the correct P/N to order them. Btw, the only ones which are standard Molex Mini-Fit Jr. connectors used in computers are the 4 and 8-pin AUX CPU connectors. The rest (6-pin for molex/SATA, 12-pin for 2xPCI-E, 10 and 16-pin for 24-pin MB) aren't standard ones (6-pin for molex/SATA has different lock compared to the PCI-E 6-pin connector) or not sold in computer shops like FrozenCPU at all (10, 12, 16-pin).

I do know they are "Molex Mini-Fit Jr." - that's why i wrote that. But finding the correct ones is a impossible task.

The difference is in the housings, not the pins. All Mini-Fit Jr. connectors use the same pin size and spacing. I assumed you meant the pins. The housings may well not be Molex. I've seen (and use) several housings for Mini-Fit Jr. pins which are not made by Molex.

Housing, whatever :D. I'm talking about the the plastic part at the end of the cable which you put into the connector on PSU - still the problem is that except the 4&8-pin connectors the rest is either keyed diferently compared to connectors sold (6-pin) or impossible to find the P/N for it (the rest).

Well the only connector which is not a standard key is the PCI-E 6/8-pin connector. All the rest are standard keying. The PCI-E ones are not easily available as the standard is not open. They simply changed the key slightly. You can scavenge these easily enough.

All the connectors on the X400 and X650 side of the cables are standard Molex keying.

faugusztin:

If you're still having trouble finding the correct parts I can supply the part numbers for all the connectors on the X400 and X650. They are standard Molex parts and easily identifed on their site.

I really like my PICO, but the Seasonic has more hookups with a five year warranty and quality indicates it will likely last much longer than the warranty period. Since I live off the grid efficiency is very important to me, but at these outputs a difference in Calculated Efficiency of maybe two percent is not significant. It just seems a better long term investment.
I'd still prefer to use a DC-DC board simply because it's so much smaller and thus allows for smaller cases to be used. I was happily using one (not a PICO) until I realised it was faulty and was destroying my hard drive!

So sadly, as the board I was using is almost impossible to replace and the PICOs don't provide enough juice for my needs, I've had to go back to using a normal PSU and abandon my plans to build a nice tidy custom case. I couldn't even afford a decent modular PSU, so I've got to deal with the mess of cables (note PSU makers, mesh sleeving only prevents me tucking them away) as well.

I live in hope that I'll be able to diagnose and fix my beloved DC-DC board :)

I think Mike mentioned earlier that they do have a 460FL, but it was a pre-production sample and not necessarily the final product.

I'd like to see a review of the passive 460 as well.

I am interested in a fanless supply but just don't think the 400 is big enough for my current rig with a 125W CPU 1055T combined with VaporX HD5770 108W Video card add to that the mobo and a dual tuner TV card. Currently I'm on a M12 II 550 Bronze.

Possible downgrades I'm considering are a move to a 95W 1055T and a Sapphire Ultimate HD5670 which is passive. I think that would be a better match for a 400W supply.

That's barely 300W even if you OC and have 4 HDDs.

I am unpacking my X-460 right now. :D

Looks to have the exact same heatsinks as in the X-400 review and weighs the same 3 pounds, 10 ounces.

I only got the X-460 over the X-400 for the extra PCI-E connector.

Get some decent case airflow on the X-460 and it can go past 460W

With prices like these,

X-400 fanless 158 euros
X-650 167 euros
X-460 fanless 186 euros
X-750 190 euros

can someone justify buying the fanless models?

Looking at the X-650 review, outside the hotbox, the unit is effectively fanless at least to 300W. The next step is 400W where it's 16 db.

I'm mainly talking about the 650 vs 460. I can sort of get why you'd buy a 400W fanless though I would never choose it.

How is the pricing around the world? Similar?

Your X-650 and X-750 prices are crazy high - they are 133 and 154 euros here in Slovakia. No X-400 and X-460 here yet.

Newegg US prices (including S&H) (note I did a google search and didn't find lower prices, though some US residents will want to avoid the egg due to sales tax).

Seasonic SS-560KM $140
SeaSonic X650 $142
SeaSonic SS-400FL $145

Seasonic SS-460FL $170
SeaSonic X750 $182

Given the pricing shove I'd call the X650 the value winner and would only consider the fanless 400W. The 460 has a $25 premium that would keep me looking at the 400W instead.

Note the part numbers are as listed on newegg. The 560 should be called X560 but they don't list it that way. They also messed up and listed a fan in the description on one of the fanless PSUs. Go figure.

Ok, some of the new models are finally in my country, so there are prices in Slovakia (including 19% VAT, price in USD is with google EUR/USD rate, 1.289) :

X-400 127.81 € (=$164.74)
X-460 139.98 € (=$180.43)
X-560 121.64 € (=$156.79)
X-650 132.77 € (=$171.14)
X-750 153.90 € (=$198.37)

Once again, your prices are superexpensive.

Sweet PSU,

See, I'm still on my Trust P150+Antec NeoHE 430w PSU, and if and when I had to upgrade I'd like to go quieter (though currently this NeoHE is prob quieter than my current System Fan). My problem is that because this PSU uses an 80mm fan, I'm able to isolate it from the system (In a very DIY manner). I like the idea of isolation and I'd like to keep it isolated, but with the X-400/460w Seasonic, I'd probably have to open it back up and expose it to system heat/airflow/etc... Either that or let it be isolated, but then have an intake fan dedicated to the PSU. This is also something that may keep me away from most PSU's these days as they mostly use 120mm fans, and those, I would not be able to isolate in my P150 at all.

Well I live in one of the most expensive euro countries I think in general. The X-560 just became available at 149 euros. Tax is included btw in these prices. I think that's a winner if I were to buy another Seasonic. Rocking the S12II-330W still. It has served well for two and a half years.

Btw using the exchange rate to compare prices between countries with different currencies is pointless. Currency changes value without price fluctuation. Actually even comparing prices between euro countries is rather pointless because the average income most likely isn't the same.

How come only Newegg is carrying the fanless models, no one else is going to sell them, such as Amazon, etc?

Promo is available on Newegg.ca now, so much for being SPCR only :twisted: - the code is right up there with the item! It doesn't even cover shipping cost.

I noticed that the cost of the SS-400FL actually went up a few days after SPCR posted it's review. Should have bought it then and there.

Yeah they are charging $10 shipping on the 460 but free shipping on the 400, no wonder they are happy to provide the coupon for the 460.
