hi, i built a new pc , my specs
(1) Core i5 4690k 3.5 to 4.0Ghz
(2) MSI Z97 Gaming 5
(3) 8 GB RAM 1600Hz
(4) Nvidia GeForce 9500 GT
(5) Screen Resolution 1920x1080 60Hz
(6) Xigmatek Tauro 500W 230V Power Supply 80+ Bronze Certified
i'll be changing 9500 gt to Msi Gtx 970 4g Twin Frozr v.... Is my PSU (Xigmatek Tauro
500W 230V Power Supply 80+ Certified) enough for the Gtx 970?
I live in Pakistan and I'll be buying the new Gpu Gtx 970 in Canada, so will there be any problem with the psu as the electric voltage in Pakistan is different than that in Canada and Americas....
do i need to change my PSU ?
plz suggest any PSU from

http://homeshopping.pk/categories/Power-Supply-in-Pakistan/ (if i need to change)
thank u
 
Well it's a relief, thanks anyway, i'm only dissapointed because i tought i got good unit very cheap, but it seems they're not so cheap after all 😀
 
well i can spend 140$ on PSU, it's a lot for me, but when i rethink what is in PC, and the tought dead PSU can bring even one component down, it would be trouble 😀
 
And that right there is the correct attitude. The psu is the most important component in any pc. It directly affects everything that needs power, and is responsible for more headaches than all other components. But at the end of the day it really does nothing for fps or gaming, so is seriously overlooked in its importance. Ppl figure any psu will do, as long as it powers my fancy new overpriced gpu.
 
I know few people, and they think exactly like you said, i talked with one of them recently:
"This is my new setup omg it's awesome, i can play anything"
then i asked if he read about any of his so beloved setup components in the internet?
"Nonesense i know everything my self, i don't need someone to point what i should buy..."
I then tried to be nice, but gave him example, what happened to me once:
"I buyed new GPU at the time, it was best of the best, and i payed really a lot, but after year, had to buy new one (if someone remember how perfect geforce 9000 series was) my cards fried..."

So in the end of this there we can do a conclusion, it's not the price that makes things good, and not the brand, but expierence, so never buy something that wasn't reviewed by experts. :)
 
Sentey appears to have had 8 models of power supplies, and all are now listed as discontinued at the link below.

Lots of power supplies listed on https://www.sentey.com

Unfortunately, they do not seem to post a copy of the 80+ label online, and the one label that I can almost read is on a 80+ bronze 750 watt unit, and it looks like the +12 volt rail does 600 watts, which would be about 144 watts short of a high quality unit.

For comparison, I patched some Seasonic PSU info together awhile back:

What are the reasons for moving the EVGA NEX 750 B to tier 4? I curious because I own one of those powering my 8370e and 280. They seemed to have Japanese primary caps. Sadly, I can't find professional reviews on it.
 


The unit I linked makes 62.5a on the SINGLE 12v rail. This is 750w. It has a 5 year warranty as well. All of this leads me to believe this COULD in fact not be a terrible PSU. It is OEM'd by Sirfa so I'm guessing it actually isn't awful.

I would like to see proper oscilloscope reading for it though.

I understand what makes a high quality unit and what makes a unit junk. This is not what I am talking about though. I wouldn't have even wasted my time posting if the 750w unit in question made less than 700w on the 12 rail.
 
What tier is a Bestec ATX0300D5WB X3? I assume it is Tier 5 but just wondering, came with a Dell Inspiron 531, looking to add an R7 250 if possible
 
Dell might happily use Tier-4 units, because they're cheap and don't support expansion (Dell would rather you buy a new system), but I'm pretty sure they don't use tier-5 stuff; that would be e-machines. Some of their PSUs are probably tier-3, especially in business boxes they don't want failing on their high-volume customers.
 
Haha. This is the listing on Amazon; http://www.amazon.com/Bestec-ATX0300D5WB-Rev-Power-Supply/dp/B0094342T4.

I don't want to buy a new PSU, just trying to salvage a couple of old pc's and make a new one. Right now I have a Dell with a old Athlon and a presumably 300W supply, and trying to add a 250 that i had before upgrading to a 280. I have another dell but only with a 250W but a Q6600 and a GT 610.
 
I found the power label of the metal blade power 750w.
+5v 21A,+3.3v 21A, +12v 62.5A, - 12v 0.5A, +5vsb 3A.

What I find funky is that 1 screen up, is a diagram with the notage about a single strong rail for 12v. Diagram posts as 56.25A.

85° Teapo primary cap for full reliability
120mm quiet (34db)sleeve bearing Globe fan (really, sleeve bearing upside down?)
MBP 750w Modular has fixed motherboard power connectors. Honestly considered Semi-Modular in my opinion.
MBP750-HS(M) tested for 80+ 1/20/2011
Tested at 20/50/100, 153w{85%)/381w(87%)/753w(84%)

Stats are decent, actually made full power under load, might be tier3 imho, but with the fuzzy literature and Teapo caps, it might be a candidate for tier4
