Thermaltake SMART PRO RGB PS-SPR-0750FPCBUS-R Power Supply - 80 PLUS Bronze - 750W

its was on sale for 65 at my local electronics store

Condolences

 

That one is pretty shitty. And for the same money you could have gotten a really great unit like Bitfenix Formula.

Can you replace it with the Gold Version?
That one is not bad.

The Bronze version however is.

Then you should've bought a better Thermaltake or Corsair power supply.

 

As Stefan said:  My condolences.

Initially was going to say it was a PUQ B Design like the non-RGB 750 Smart which is decent at worst, but nope, it's an even worse Sirfa design...

oh, its Sirfa?
If the 750W is anything like the 850W, it isn't as bad as I thought:

There is also this group regulated RGB Thing that seems to have ChengX Caps and stuff like that - really not great...

It's the same platform as the 850w, performance (on the 850w at least) is... *passable* but it's not as good as competitors (CXm etc)

 

2.56% Vreg average, 1.5% on the +12V (3.3V was 3.8%!), ripple was good on the 3.3 and 5V, but 12V was at 40mV which again, is just a bit short of competitors.

 

Bulk cap was a Rubycon, others were Teapos, protection IC is  a PS224 which has OVP/UVP/OCP, Thermaltake claims it also has OTP/OPP/SCP, obviously not through that IC.

Going to it's product page lists a bunch of "750w" reviews, they are actually all 850w reviews, so we can only assume they perform identically....

Irrelevant, what counts is +12V, rest is not really important...

What is important that it does not matter how the unit is loaded.

If you have 0A on both minor rails and everything is well within spec, its fine.

1.5% on the +12V

Yeah, so not that bad and perfectly fine...

 

2 hours ago, awesomegamer919 said:

(3.3V was 3.8%!)

...wich is still well within spec as its +/-5% so no problem there.

Less of a problem since that rail isn't really used today...

...and again, totally fine and only around 1/3 of the specification.

So no Problem here either.

Teapo SC isn't great but they should be fine for a couple of years.

 

And OPP is implemented in the primary side, OTP can be implemented in various ways, doesn't have to be in the Supervisior IC. 

And SCP is part UVP, part OCP...

 

And the competition isn't really that strong in this area...

 

 

So everything is perfectly fine with this unit, nothing wrong with it. 

I don't see anything wrong with this...

Voltage Regulation is OKish, especially on the important +12V Rail, Ripple and Noise also seems fine...

 

So he got lucky with this unit, it isn't the shit the other Bronze RGB units are...

If we go over to Toms, Aris had worse results with the unit (And considering he has better gear than Jeremy, his results are going to be a bit more accurate)

 

"Load regulation on the +12V and 5V rails is within 3%. It's quite loose at 3.3V, though. Moreover, during tests #10 and #11, this rail drops its voltage below 3.2V. While the 3.3V rail is only lightly used, it still needs to stay as close as possible to the nominal voltage. Load regulation at 5VSB is quite bad, landing to close to 6%."

 

Looking at the actual graphs on test 1 at ~85w 12V was 2.13% which is the furthest it go from nominal, 5V started at 5.07V at light (~85w) load, so that's 1.4% away from nominal  (I know 5V/3.3V isn't used all that much, however it is still used), 3.3V was especially loose, at 3.4% (3.189V)...

 

Fan RPM was also quite high, at 1300RPM minimum (34DB) by 300w it was up at 1600RPM (39DB) and by full load it was pushing 1850RPM (44DB), for reference, the CX750m fan doesn't even turn on until 300w! (Although if you do actually push 750w through the CXm it can get quite loud, as much as 50DB!)

 

It's not a horrible unit, but I wouldn't say it's exactly great. 750w Bronze units are pretty dumb in general, unless you are using a bunch of high power draw older components, but that's a discussion for another day.

@remoOn the last page you explicitly said you had a BRONZE PSU but now you say you have a GOLD one?

Smart Pro RGB 750W and 850W use different platforms. You can tell by the different transformers, different VRM boards, different length of the heatsinks and placement of diodes on them, and capacitors in different places.

I actually can't, since I don't happen to have two eviscerated PSUs in front of me right now.

 

If that's the case, though, maybe the johnyGURU site may want Thermaltake to stop linking to the 850W review in their 750W list of review links:

Still well in Spec, so what's the Problem? What are you talking about?!

Especially since we are talking about a cheapish unit, can't expect awesome here...

 

 

And the spec for the 3,3V Rail is 3,14V minimum, so the 3,2V you are mentioning is perfectly fine.

Especially since that rail was never really used and still isn't.

If you get something like 5A, that's really really much...

 

Its one of those Useless Bullshit Things that someone thought was a great idea 20 Years ago. Well, it was not, never was. It was always rather useless.

They should have stuck with +5V...

You fail to mention that those things are measured at high Ambient Temperature of 40-50°C.

Some PSU don't like that and their fan RPM goes through the Roof.

So I woudln't give too much about that, because of that...

Since when is the CX-750 Semi Fanless?!

Corsair doesn't mention that on their website.

YOU are overreacting.

Specs are there for a reason.

This unit does NOT violate any spec.

Its well within specification, topping it by a mile.

With that I totally agree.

If you need 750W, you should get the Gold ones because they are just soo much better in every way - higher quality fan, less noisy, just better (Com-Traya)...

The mention about the 3.2V was a quote directly from Aris

38-46c Ambient, so on the lower side, when tested at 30-32c ambient these were the results:

That's still bordering 37DB at 300w...

Ahh, I misread it, 750ish RPM under low loads, still a good 9DB below the Thermaltake:

Again, I prefer units that perform well over those that are just "in spec"...
