hello,

Recently bought a 650w Superflower PSU and due to a price lowdown also got a MSI GTX 770 lighting graphics card.
I dont really trust the calculators on the net so please help me with some advices.
My rig:

AMD phenom 955
8Gb 1333Mhz RAM
4 fans counting the one on the CPU cooler
1 HDD planing to get 1 more and a SSD
1 Fan controler
7 USB slots occupied
Asus M5A97 mobo

It will be just fine for a single 770, but your CPU will bottleneck that GPU in many games.

Superflower is one of the best PSU design..
The highest tier until the lowest tier using single design, that why this psu is cheap, but still powerfull..

You have a plenty headroom with that psu..

You mean Superflower , and for SLI of 2 770's I would go at least a 750w to 850w.

I wouldn't suggest running 2 770's an any 650w PSU not matter how good it is.

i dont plan on putting 2 in sli, i just want to know if the psu can handle a full load for an extended period of time

With a single 770 , it will be able to handle it.

Best solution

well..that PSU will handle sli 770 flawlessly..

A system with Intel Core i7-3960X, ASUS P9X79 Deluxe, 16GB Corsair 1866MHz, harddrive, etc etc and GTX770 in SLI mode just consume 552 watt in gaming mode.



Sooooo...no matter how good is a 650 watt PSU, this is will able to handle 552 watt system, right..? :D

i installed the card and when in idle :
+3.3 V = 3,312
+5V = 5.078
+12V = 12,046

when in load :

+3.3 V = 3,312 => 3,288 then 3,264V

absolutely fine..
3.3v will safe within 3% range..3.201v -3.399 v
5v will safe within 5% range..4.75v - 5.25v
12v will safe within 5% range..11.4 - 12.6v

12v rail is main concern in modern psu..
Because almost all component is powered by that rail..

there's nothing have to worry..
If it still within range..and it's very normal if you see a little voltage drop while you put load to your PSU..

well, there seems to be a problem.
i was playing a game and the 3.3 voltage dropped from 3.312 -> 3.288 ->3.264 -> 3.240.
after about 3 minutes a beeping sound started from the case.
i need to mention that i have a UPS attached to the system.
and i have a speaker mounted on the motherboard, thats where the beeping started to come.
