What is the hold up time

Solution


Missed that G, the GS is (was) actually a pretty good PSU, about mid-range for gaming models. Your new one should run fine, but it's just not the best quality http://www.corsair.com/en-us/power-supply-units The CS-M are in the mid range of Corsair line. The RM and AX are the good ones from them, but for those prices there are other models you can pick from.


I bought Corsair CS650M and many reviews tell that its okay not good but most worrying part is its hold up time is lesser than ATX requirement and at some post I saw if u have ups then it might switch off while converting main to ups.

I have no opt cuz i bought it 🙁 I just wanna know this wont burn my card mobo or do something like old GS600 did with my gtx560 ti

my specs for which i will be using

i5 6600K
z170K
16GB Vengeance
850 EVO
1tb WD Black
4 Fans
Air Cooler for cpu
 
Hold up time is just how much capacitance the PSU has. It just means if you have some power fluctuation where you are getting say less power than you should from the wall the PSU has 11.6 ms where it can provide power. This is a pretty minor factor to be honest and if you live where power has a ton of fluctuations a UPS would do many factors better for hold up time than even the best PSU. The best PSU hold up times are in the 30ms range.

Hold up time:
"The amount of time, measured in in milliseconds that a power supply unit (PSU) can maintain output within the specified voltage range after a loss of input powe"
 


So you had an issue with a Corsair CS, then you bought another Corsair CS to replace it, plus it was bought even though you saw reviews that said it was not a "good" model to get. You would want to ask first, buy second.

It's not a horrible PSU, but not one I'd use in a gaming system, I'd spend another $15-20 on a better model. Return it or sell it if you are worried, or use it if you don't want to return it. It will power the system OK, just won't be the most reliable model. Anytime you are going to the low range of a product line you are obviously not going to get the best quality.
 


Old one was GS600 this is "CS"

Well that shop has 7 day replacement so I will ask them or else i will sell it
