Corsair 620HX vs 750TX

[Howie]

Which one is better? The 620HX has tons of reviews, while the 750TX is pretty new. Which one is better build quality/performance wise? Quietness? The 750TX is actually cheaper than the 620HX now.

 

[zerogear]

my 620HX is nice. And I stick strictly with modular PSUs nowadays.. 750TX isn't modular, so it should be a little cheaper.

 

[TridenT]

Performance wise? 750TX Wins. The 750TX is pretty quiet as far as PSUs go. It isn't modular and can be had for 100$ so... You choose.

well Oklahoma Wolf and madmat over at JG.com and Paul Johnson at HardOCP found the TX750 to have rather high ripple.....but those were at wattages you will probably never see, and Yellow/Redbeard said their engineers were working with CWT to reduce the ripple. Anyway both are good

 

[Howie]

I want a modular PSU, but the 750TX is slightly cheaper than the 620HX right now. And if it has more power, performs just as well/better and is just as quiet and reliable then it's pretty much a no brainer absent the TX not being modular?

 

[IEC]

I got a TX 650 and am very satisfied with it.

Much more power than I need, but I buy power supplies to last for ~5 years. (Last one was an Antec True430 which lasted nearly 6 before smaller caps started leaking)

I just thought of a question maybe someone here can answer.. Whats so good about a modular power supply?

In working with video games and pinballs, one of the 1st things to fail is the connector(heat). So is there a reason why they went to modular and added a connector(other than looks)?

Less clutter can improve cooling in a case, use what you need scenario

Hmm, this makes the HX line the choice for me.

Hey Guys, my 620hx is ordered so i'm hoping the the 12 volt rail w/ 18A is enough to run a ATI R4850 video card..
Appreciate your sharing info on this question !!!
I favored the modular to help keep my Antec 900 case clutter free for looks & better cooling !!
Thanks Ol'Pal

you mean 50A...

 

[OLpal]

I looked on MSI site & Da'Egg site trying to find how much power she'll draw, but didn't find it !!!
So even though they're 18A per rail it'll still pull up to the 50A you mention ???
+3.3@24A,+5V@30A,
+12V1@18A,+12V2@18A,+12V3@18A,
- 12V@0.8A,+5VSB@3A
combined 50A on triple +12V rails

Is this correct ??
Thanks QuickSilver; Ol'Pal

By how much you recon? .05 of a degree...

[HOOfan 1]

HX620 label says 3 12V rails at 18A....in reality it is a single 12V rail at 50A. Even Yellowbeard and Redbeard (Corsair employees admit this).

PC Power and Cooling FUD is against modular cabling...

 

[tr1kstanc3]

i have the 520hx and it powers everything in my sig just fine.

 

[Howie]

I read a review that said the 750TX is louder than the 620HX. I think I might go with the 620HX if this is true.

 

[OLpal]

Thanks for the peace of mind Guys !!!!
Corsair 620HX & MSI R4850 video card both arrived @ same time, surprised me !!

HooFan, i Am wondering why PC Power and Cooling FUD is against modular cabling...

All i need to do now is decide between E8500 {$189} vs. Q9550 {$329} & this performance review is making me wonder if i wouldn't be happier with $140 in my pocket & a faster-cooler E8500.. ps: i don't do video encoding.

Mostly because they don't want to be sued by Ultra (the patent holder) for using it, and since they can't use it they have to say it is crap.

Sure modular connections add resistance, but so do cable extensions and the connector from PSU cable to component.

 

[RallyMaster]

OP, depending on how much stuff you're throwing into the computer, I'd say even an HX520 is fine for your application. If you do plan on going with something like Crossfire down the road though, the HX620 is the sure bet. I've used my HX520 for two builds already and it's live and kicking...

That's what cable ties are for.

Modular PSUs are for people who don't know cable management from time management.

Okay, that's a bit harsh and untrue. However, modular cabling having a measureable temperature difference over non-modular cabling (bundled with a single tie) is probably null.

Sure, it's nice to not have a bundle of unused cables, but basically all the cool kids have modular PSUs so you either buy one or you're not a geek, but a nerd.

Ultra won't sue anyone if they pay the royalties. No, PC Power & Cooling basically marketed FUD on any technology that they didn't implement into their own units. This included (IIRC) modular cabling, multiple rails and fans larger than 80mm.

As for extra resistance, well, as long as the end result is within ATX specs, why worry?

WELL STATED!
