Someone already posted this they look like shit imo not even that cheap.
 
In what world do you live in where $35 for a brand new Seasonic SS-650HT (aka the S12-II) is 'not even that cheap'.

I guess there's a reason it says 'n00bie' under your name. :D



For those curious, these are legitimate deals on brand new system pulls. The seller (AscendTech) has always been fantastic to deal with and ships super fast. These ship OEM style bare without a power cord, but are fantastic for the price.

That SS-650HT for $34.95 shipped? Over $100 on Newegg for the exact same unit:

Seasonic SS-650HT 80 Plus Bronze Certified 650W Active PFC ATX12V (v2.2) Power Supply 12cm Double Ball Bearing Series-Newegg.com

Similar price differences on the other two models listed in the original post.



BTW, if you don't feel comfortable ordering on Ebay they have an Amazon store as well:

The unit being sold on newegg has reviews dating from 2006 to 2009. I am guessing someone is getting rid of new old stock. $35 for a unit designed 10 years ago doesn't seem that hot to me either.

It conforms to the latest ATX spec, so the "old design" is fine.

I'm the one that originally posted about this a while back. The only real downside is that it isn't modular. For the price, it is an awesome deal for a good, high quality PSU.

They are brand spankin' new. Not a bit of dust in them.

I bought 2 of them for use in a couple retro boxes.

Interesting, what would be your preferred quality PSU at this price point. And could you tell me the date said PSU was designed?
 
Thanks for posting this. Helping a friend build a gaming computer for her son. This just cut $15 from the build list I originally gave her and got a better PSU than I had suggested.
 
Can't beat that price. Picked up a 650 for testing / spare rig use.
 
Picked up the 550 for an older system. At $21, I figured "why not?". I don't think going to 650 would make any difference, and at $30 plus thats closer to the price I would want to pay something that comes with a warranty.
 
You know, I think the real price vs performance hero in this sale may be the 600W. It's only 50W less than the 650W, but cuts off almost 33% of the pricetag. Meanwhile the 550W is 50W less than the 650 but only 2 or 3$ off. In terms of price vs watt calculations, this is actually proportional. Just the 650W seems to be much more expensive for some reason. Does it include an extra GPU line or something? I don't think I'd want to try to run SLI off of these either way so that would be pointless.
 
Good deal! Unfortunately Multiple 12V lines and no modular kills it for me.
 
I went ahead and caved in for one of the 600W ones for... umm... <insert reason here> Well maybe I could use it to help with a friend's rig or maybe it'll be quieter so I could use it in one of my secondary rigs. Either way, 600W for 23 bucks is a fine deal to me. I'm not sure why the 650 is so popular at an almost 50% markup for <10% more wattage (that you probably don't need for anything...), but whatever. To each his own. Enjoy your PSU's everyone, I'm eager to see how mine'll turn out.

I don't usually buy power supplies at this pricepoint. If I wanted something in the 650W range I would probably be looking at a unit from eVGA or Seasonic with a 80plus Gold or better efficiency and 100% Japanese caps (about $60 to 80 when on sale). This particular unit is non-modular, has 9 molex connectors which must be hidden away in the case, and the cables are not sleeved. This makes the unit not such a hot deal for me personally. If you are looking to spend the least amount possible and every dollar matters, then this unit may be attractive to you. To each his own.

I don't know when the specific 650W unit referenced in the OP was designed, but the reviews on newegg for the unit range from 2006 to 2009, which would suggest that the design of the basic unit is about 10 years old.
 
What exactly would lead you to assume that power engineering from years back is suddenly worse than current designs? What exactly has changed so drastically in the last few years? I'm still using UPS units from several, several years back (predating these) and they're built high quality and like tanks. Many very old speaker amplifiers are prized today as they were built using very high quality parts back in the day, and are still audibly relevant (generally superior) today.

Seasonic is a brand known for using high quality designs and parts. If anything, reputation tends to precede a decline (that is, I would expect newer models to eventually start skimping out on the design after gaining a good reputation, which is almost always true with trusted brands as the higher ups get greedier). Everything else you point out sounds like a personal issue. If you're looking at budget PSU systems that are high quality, modular units are difficult to find, and many don't need a fully modular unit if they can manage cables. Energy efficiency is hit or miss. Will 80+ gold save you enough electricity over the computer's lifetime to make up for paying 3-4x the price? Probably not, and irrelevant anyway as most builds are done with "what I have right now" money.

The point is that if you're on a strict budget, you can't get a PSU at this quality level and wattage for anywhere near this price normally (especially the 550/600W units' price level). Anything you don't use on the PSU is free to use towards a better GPU. 40-60$ towards a new GPU/CPU/etc. is rather significant. Normally at this price point the best you could get is a Corsair CX PSU at Microcenter. If that. Would you rather have this Seasonic or a Corsair CX?
 
Just for those looking for honest relevant info on this unit (the SS-650HT in particular):

1. It IS a DESIGN that's at least ten years old. What that means is that it's an older group regulated design and some newer and more expensive units with independent regulation for each rail could outperform it especially when transient loads are applied. Group regulated also means that it's got multiple +12v rails which is not a big deal assuming you pay attention to how you distribute load in the rig you're building. This ten plus year old design is good enough that the platform was used for loads of builds from Corsair, EVGA, BFG, etc for many years.
2. The PSU holds 80Plus Bronze certification and has since 2009. You can see the test sheet here.
3. A few people have asked what kind of current rig these can power. My answer is pretty much any single GPU rig, although I'd leave out rigs with a monster TDP CPU like the 140w Broadwells. It will even power some mid tier multiple GPU setups without breaking a sweat.
4. These are OEM style which means they have no flashy paint job and no cable sleeving. If the kid's PC or grandma's PC has a window, you might want something that looks flasher. :p

Long story short it's a good solid proven build. It won't win any beauty contests and might fall behind when compared to more modern platforms, but it's $35 and will probably send a similarly rated EVGA crying home to mommy.
 
I bit on the 650w because I had some ebay bux come in. Took it down into the 20's

You know I don't mean to keep railing on about this... but why is the 650 so popular when the 600 knocks almost 33% of the price off for only 50W less? What do people expect to do with 50W more that they couldn't do with 600W? Just baffles me. Then again, it's only 10$ absolute price difference, so I suppose it may just be inconsequential...

Not sure how anyone could complain about a seasonic 600w PSU for $23. These are absolutely awesome for someone who builds a lot of systems. With my ebay bucks coupon just bought 4 for $70. Can't beat that.

Hell, I'm not knocking it at all! Keep on harping on it! For some reason I have that 650 watt unit on the brain, I think because the other thread is centered around it.

Heck, the 600w unit you're referring to (the SS-600ET) is actually sitting at just under $24 shipped, like you pointed out.
I believe that particular unit is actually damn near identical internally to the PC Power & Cooling 'Silencer' Mark III (minus the modular capability and smaller fan) and although it lists the rails as two separate +12v rails (at 24amps) on the Seasonic label I'm pretty sure it's actually a single 48 amp rail. That may actually make this more desirable for some folks especially at $10 less!

Is there a difference between an "ET" model and an "HT" ? That was one thing I noticed about the 600w vs 650w.
 
In for a 650 watt. Never hurts to have a solid PSU lying around just in case. Seems when i NEED one is when nobody wants to put one on sale.

I'm currently running crossfire RX 480's off of a 650w unit while my EVGA PSU is being RMA'd. While mining 24/7, the unit doesn't even get warm.
 
After much searching, I found the datasheet for the 600W version:
http://seasonic.com/main/wp-content/uploads/2015/06/SS-600-500-450-400-350-300ET.pdf

It does not list PCIE connectors. I can't find any info on the 650HT model however. I'd assume it doesn't have PCIE power connectors either. So be aware you'll have to use a molex-> pcie adapter if you do buy this.

Cant speak for the 600 but the model ss-650ht is still sold on newegg and has 2x pci-e 6 pin connectors. Unless its a new hardware revision being sold under the same model number.

The SS-600ET has a set of 6-pin and 6+2 pin PCIE power connectors. One of each.
The SS-650HT can have either the same as above, or two 6-pin connectors depending on date of manufacture and trim.
 
Is there a difference between an "ET" model and an "HT" ? That was one thing I noticed about the 600w vs 650w.

The 600 watt SS-600ET is a slightly more modern design. The number of +12v rails is listed as two at 24amps (instead of the four at 18amps of the SS-650HT), although I could swear this is actually a single rail unit. My memory fails me at the moment... With this being a slightly newer build it will have certain differences like the addition of a 6+2 PCIE power connector.

Some versions of the SS-600ET also lack a 3.5mm floppy drive style power connector, although Seasonic would usually include an adaptor in such cases.
 
I messaged the seller asking if the 650 has the PCI-E connectors or not.
 
Based on a Silentpcreview of the Seasonic S12 550 and 650 (consumer versions of the Ops PSUs?), I am thinking the only difference is the that the 650watt unit has a higher speed fan and perhaps different PCI-E connectors.
 
The closest i could find to a review for the 600-ET is this:

PC Power & Cooling Silencer Mk III 600W power supply Review

Yes its for the "PC Power & Cooling 'Silencer' Mark III" as referenced by Noxtek in his post above, but Jonnyguru references several times in the review that the psu is based of the same model and components.

It is indeed, and it was used in a lot of other builds from various manufacturers too. I think just about every GOOD PC Power & Cooling unit was based on a Seasonic platform, save a couple of crappy ones they came out with after they were acquired by OCZ.
 
Looks like they jacked up the price on the 600W model a bit. I don't have the hubris to assume I caused this, but it is rather timely.

Probably automatically setup to adjust the price based on units on hand. It only went up $1.25. I bought 4 myself yesterday.
