Chieftec Nitro SPS-750C 750 W

[crmaris]

Chieftec recently made a new addition to their product series with the inclusion of the Nitro 88+ line. The new PSUs are 80PLUS Silver certified and promise efficiency that surpasses 88%. They also utilize a semi-modular design and their OEM is Channel Well (CWT), a respectable manufacturer.

how did this get an 8.0? It's literally a fire hazard! How did you base the scale?

Well, it would do its job in a modern computer, but it did lack some build quality, so I can see an 8 being reasonable. And, no, it isn't litterally a fire hazard.

Is exposed bare wires capable of shorting not fit your definition of a fire hazard? Stop trolling.

 

[crmaris]

I exposed on purpose the wires to show the bad joints. The heatshrink was covering them of course. Although I would like it to be more tight on the specific cable.

Also the PSU does not catches fire so easily since it has SCP protection. Even the cheapest ones have this protection.

There were not exposed wires, there was heatsink covering them, it was loose enough to be moved when the unit was taken apart.

And as crmaris points out, even if they were exposed, the Short Curcuit Protection would prevent any fires.

So try actually reading the damn review before accusing others of trolling because they disagree with your initial trolling.:shadedshu

yes but my point is the combination of horrible soddering, exposed wiring or wires with questionable joining, could cause at the very least a loose wire, bypassing safety measures causing a short to ground or worse. which is why i asked why it would rate and 8 out of 10

Chieftec is a well known PSU manufacturer in my country, and has a very good reputation of quality budget PSU. I had 350W Chieftec and it powerd PII X3 and Radeon 5770 for a year until I replaced it with modular Chieftec CFT-600-14CS... Just because it is not well known in America and UK doesn't mean that is bad...

Seems gary has a valid point, question is did you read the article?

The bad thing is that whoever made these joints left the soldering iron on the 3.3V cables so it nearly melted them and on top of that the joints are far from good. Also the heatshrink on one of them is loose enough to slip and provoke a short circuit, if the naked cable touches the casing.

If I had a PSU that was built as dysfunctional as this one I wouldn't give it an 80% accepted rating either. On top of that the reviewer guessed this was a pre-release sample and never even asked the manufacturer about the piss poor wiring job.

No, he didn't have a valid point. There were no exposed wires, the insulation on the 3.3v was nearly melted, but it wasn't exposing any wires, and the solder joints were covered with heatshrink. The soldering wasn't great, and the heatshrink was loose but not loose enough to expose wires without first taking the PSU apart and moving the heatshrink yourself.

Yes, I read the article where it says there were no exposed wires. Gary obviously didn't, and just looked at the pretty pictures and went into full on troll mode screaming "fire hazard".

I'm not arguing the score of the PSU, I'm arguing weither it is a fire hazard or not, and it isn't. Gary went into full on troll mode without actually reading the article, and the proof is the fact that when correct, he started name calling right away instead of trying to make a valid point(or even going back and making sure he wasn't full of shit).

Personally, poor astetics that have no effect on the functionality of the unit, shouldn't really drive the score of the unit down all that much.

I am quoting you cause it is obvouse what someone else is doing and i don't want to encourage that behavior.

As you can see from the pic there is wire insulation... exposed wire... wire insulation with heatshrink i don't see how this is so difficult. Do you think that wire is an internal one for the pcb cause it's not it is exposed thus prone to wear from routing and hooking it up ect.. that is ONE reason why i asked how this got an 8/10

8.0 is the lowest score given I believe unless someone can link a review with a lower score?

recently I tested a PSU and in normal temperatures all were fine and it had perfect ripple suppression. Hoever, when I raised the temperature to 45 C ambient then all hell broke loose. At 10-60% load I saw even 180mV ripple at +12V!!! instead of 30mV I had at room temps (also ripple in the minor rails was excessive). The weird thing is that at 80 and 100% load ripple was normal even with 50C ambient.

Bottomline. A hot box some times makes a huge difference. Otherwise the above PSU would flew under the radar.

Just seems like an awfully high score?

[crmaris]

Yes I am the same guy and the post you are referring to is 4 weeks ago and I was giving an example to a fellow reviewer why he should use a hot box. I was not referring to the Chieftec since I only got it last week. Again read the whole thread not the parts that suit you!

For the last time I am gonna tell that the heatshrink was there and I removed it to photo the joint, if you can't understand it I can't help it. The wires are a damaged but not exposed.

As for how I know this is a pre-production model, when you have test over 60 PSUs then you know how to distinguish a pre-prod. model. But the thing here is that I rated the sample I had in my hands. According to its performance and the flaws I saw I decided to give it an 80%. If you don't like how I rate it then stay on the other pages of the review.

If I wanted to make it look better (as you imply) I wouldn't show any pictures of these joints neither close ups to the main PCB. You see last time I checked I didn't have any Chieftec stocks.

 

[crmaris]

On top of that the reviewer guessed this was a pre-release sample and never even asked the manufacturer about the piss poor wiring job.

And how do you know that I didn't ask the manufacturer about that? Also how you are so sure that I cannot distinguish pre-models especially when I have reviewed numerous CWT DSGs.

Because if you asked you would have worded it without the word guessed involved. Look I'm not trying to headhunt here. I just think the point is valid. You say this unit specifically could easily short, and potentially damage other components, yet still give it an 8/10.

a little hostile don't you think? I implied nothing i asked how you came to the conclusion of 80% that is all... and to quote you

The heatshrink was on the naked wire. I moved it back to take the photo.

why would you remove heatshrink to take a pic? Unless it was reallllly loose and viable that it would short

if 3.3V or other rail short then the unit will shut down. It has SCP.

Again, because you obviously have a hard time reading, the wire wasn't exposed, the heatshrink was removed by crmaris to show the sub-par soldering. Why is that so hard to understand, you've been told it at least 3 times now!

 

[sneekypeet]

In a perfect world yes, but things happen, just like the poo soldering that was going on inside. Like I said man, if it had been confirmed that a PSU that I buy isn't some garbled mess inside, I see the 8/10. If there was any chance my unit would arrive like that, that the angle of my approach.

 

[crmaris]

because I wanted it to see why 3.3V dropped so low at full load. Normally you can't remove at all a heatshrink unless you cut it along. This one, after a 4-5 minutes work I managed to remove it.

I also tear apart the whole PSU to check it and to show it to you.

I think you need to step away and let crmaris handle gary's inquisitions into his work. Take this as a warning that you don't have any place to continue your gary cant read troll!

Because of that before the rating I give a full analysis on the PSU. So anyone can decide whether he will buy it or not. In my opinion it deserved 80% for others not. Unfortunately I cannot rate according to what anyone else wants but judging on my personal opinion.
