SilverStone ST75F review is now live!

[jonnyGURU]

http://www.jonnyguru.com/review_details.php?id=43

Squeaks by with a total score of "9" despite an 8.5 performance score.

So why is it recommended even though it was shaky at 750W and had mediocre efficiency?

Because it's modular, quiet and comes in at a great price.

Check out the review and discuss here. :)

Awesome review.

I am a little sad that this thing can't compete with the bigboys at its maximum output, but I do think that if I got this thing it would last me for a while. i mean, hell, INQ just ran an article on how an 8800SLI superrig (2gb, Kentsfield, Plenty of peripherals) ran just fine on a 500W PSU with peaks of 430W. Amazing.

Since I am hurting for a modular PSU and want to keep it under 200 bucks, this sounds great. 140.00 at Case-mod right now!

jG, is there any way you could report cable lengths? Since this is a modular PSU and I am putting it in a P180B, I kinda would like to know this thing will eventually FIT without an extender in my case. Thanks man.

Again, tight review, look forward to picking one of these up sometime soon.

killnine, it will be found half way down this page http://www.silverstonetek.com/products-75f.htm

jonny, the ripple was kind of odd, need to read what OK Wolf has to say.
I think this platform has reached the ragged edge, not bad but just don't stretch it again ;)

Dude... The cable lengths are in the review. :lol:

Look at the table that shows how long each cable is (bottom of page one.) That's what the "550mm" means after each type of connector. ;)

I agree. I do think this is a case of "let's push this platform as much as possible." You can only squeeze so much juice out of this thing before it's time for another platform.

It's not too bad - this isn't an independantly regulated design from what I can tell, so some interaction between the 5v and 12v is to be expected.

If it's not independantly regulated, why does it have three pots on the side of the unit? Am I missing something?

[CAD4466HK]

Why would Silverstone over rate the flagship of the Strider line:confused::crazy:
Surely Enhance is capable of 750w+

I hope this won't turn into a trend with Silverstone:o

[jonnyGURU]

Enhance is.

Just not using this platform.

[CAD4466HK]

Sure, and what are the chances of a Strider owner pulling more then 700w+
They reserve that honor for Etasis.

[GalvanizedYankee]

CAD, this IS the end of the line for this platform. I got a ST60F here to use on the next build. jonny reviewed it very well indeed. The efficiency is just a little low at 75%+. I might jump all the 12V rails on this thing for 42A.:eek:

If jonny says this ST75F is a bargain and do not fear using it. *shruggs* Use it!

http://www.enhance.com.tw/ did have an 850W listed last month but seems to have pulled it off thier site. CoolerMaster is using that platform? iirc.

EDIT: They probably pulled it because I brought it to EnhanceUSA's attention and mentioned the UL on the CM PSU ;) I call them on the phone about once every six weeks. They are local for me.

[CAD4466HK]

I agree, 99.99% of users will more then likely "not" run into any issues
with this PSU:D

But it's the 1% that are looking for the best bang for their buck, and already
have $3000 invested in their rig{10 drives,WC,SLI,lights,fans} but "will" skimp out on the PSU;) And grab this flagship Strider, thinking their in good hands,
so what do they do? Add 5 more drives, lights and ect.

All I'm saying is why have a 750w Strider?
Stop the line at 600w-650w, then let the Zeus and the Olympia series
regin supreme:)

Or let me guess, they can make more money on the Striders vs. Zeus
being as they can crank em' out faster for cheap and not everybody can
afford a Zeus;)
It all comes down to money, one way or another:p

[GalvanizedYankee]

The Striders are modular and Zeus is not! Some must have sleeved modular no matter what :P
Enhance builds good stuff, I'd have one over a Fortron ;)

[GalvanizedYankee]

I need lunch! I screwed up this post!

If it's not independantly regulated, why are there three adjusting pots? Am I missing something?

That goes without saying on the FSP
I endorse Enhance myself, but I can agree with jG on the platform getting a
little long in the tooth;)

I know their modular and the Zeus is not,
But I only look at brute performance, not "bling"
Modular is good, but not necessary IMAO :)

Not sure - likely one or more of them is for the protection circuitry and/or maybe fan controller. From the looks of it though, there's only two mag-amps on the secondary side which means group regulation instead of indy. Probably ran into the same space issues that prevented FSP from going indy in the Epsilon.

amen to that! :)

You are so right, I remember now. The VP in charge of USA sales said one was a current limiter. I had him on the phone and he talked to the one engineer here State-Side in Chinese. That was awhile back. I guess the other one could be used for the fan's thermal ramp-up setting. I had an early Fortron with a 120 fan that had one pot for setting all three main rails and another for it's fan.

Your the man OK, I'm still the willing student :)

[Oklahoma Wolf]

One could be for 3.3v - if it really is group regulated, the final one would then be for 5v/12v.

[killnine]

I can remember 3 years ago when my friend really thought he had one of the best power supplies out there for 120.00 (I believe it was an enermax 500W). I am very discouraged that having a stable system means paying upwards of 300.00 for a power supply.

I dont think my rig will likely use 750W, or even 700W for that matter (and yes, I am one of those people who needs sleeved, modular PSUs). However, I find it increasingly hard to believe that the components cost so much that they must jack the prices so high to keep margins up. I just dont believe it. Each of the companies manufacturing likely has an established facility with an established engineering base to create products. So why the hike over the past years?

BTW-- thanks for the key in on the cable length issue. I guess that bit of the review just sorta flew past me while I was reading through. I was very intent on getting to the stability review. =D

[jonnyGURU]

killnine:

You are correct that companies have established facilities, engineers, etc. but that's not the problem and they're not trying to make "more margin" with each new model.

The PSU's that put out more power need more expensive parts. It really is that simple. And the problem with power supplies RIGHT NOW is that manufacturers are not given the luxury of making up for start up costs, because by the time the manufacturer can start making a profit, the product is already near end of life (EOL) and they have to start working on the next higher power unit.

That's part of the reason why you're seeing certain brands "jump" OEM's to others because it's all a game of who can get what cheapest and fastest right now. If you stick with one OEM, you may end up paying too much for the product or end up with a product that is "rushed" and doesn't perform as it should because they're scrambling to keep up!

[killnine]

Thanks for the lesson. I am not trying to be a prick towards power supply companies. I really think that the technology (and testing equipment) of today offer the most reliable power possible to consumers. 5 years ago, a PSU was just a gray box everyone needed to run their PC.

However, to someone that is uneducated with the fabrication and history of PSUs (me), it just seems bizarre that we can cram millions upon millions of transistors onto PCB, create fabs that build smaller and smaller processors, and make enormous leaps in performance per watt in other realms of PCs, but still have so much trouble dropping cost associated with PSUs.

This is not to say that the aforementioned designs (CPUs and GPUs especially) have not increased with cost, but I would go so far to say that they have advanced much a greater distance in performance in relation to the price jump.

*shrug* Just the $.02 of an Junior EE student....


BTW -- this is getting me more and more interested in analog and resistive networks. I really want to do some studies with things like Watercooling pumps and waveforms they may induce into various power supplies.

Hi,

I buy this psu.

The 12v line value is: 12.51v, it's ok ?

my pc: p5w dh, E6600, 7900GT, 2 panaflo 120, hardcano 13 and 4 fans 80mm

Thks

[Spectre]

Spec is 11.4 to 12.6

[hcapstan]

Yes, this value is in 5%, but, is it very high ?

[GalvanizedYankee]

ATX spec permits + or - 5%, so 12.51V, while a bit high, is lower than the 12.6V upper limit.
Software generated readings don't count for much, voltage readings must be taken with a digital multi-meter.

[Kab]

Its OK :)

I see this value from the BIOS and Soft, both are similars.

I will read with a multimeter.

Thks !!!

[hcapstan]

BIOS: 12.51v
Multimeter: 12.19v

:(

[Spectre]

There is nothing wrong with that.

Yes, off course, but the mother is very lier :@
