The HX520 is a 480 watts PSU and its really old so you really should get a new one.
For a system with a 750 card you can power that with a 350-400 watts PSU just get a decent one, there are options in that wattage range in the OP on the first page.

I'd use 8-16gb of DDR 1600 RAM so I don't need lots of power. Budget is tight and I'd swap out for better components when I have more money. I want to buy a SSD but since I have SATA2, it won't reach its potential. Also, I don't like the current setup - a large Antec 300 case with a giant cooler. I want a smaller case.

I was considering a SFX PSU but there's mixed reviews on the Silverstone.... any advice? I would like to get a cheap case ($50 range) and keep my psu for now but not sure what to do. If I go for a new psu, what are the options?
Sounds like the weirdest setup I have seen. G3258 is not worth it's money, i3 or AMD is better...
750 has no power, why not get a better performance for cash with AMD GPUs? Plus AMD CPUs are a better deal when on budget.
APU A10-7850 doesn't seem like a good deal when compared to other options = combinations of dedicated CPU+GPU though, so stay away from APUs.

It's actually quite easy, at least in US to build a tiny budget micro and mini ATX PC if you want the small form factor and don't plan to add many things.

Getting something now and upgrading later is a bad idea, you will spend more. Just save for a longer time and get what you want then. No point buying G3258 if you plan to change it a year later, same with GPU. You can get AMD GPUs second hand for half their price usually, makes them a no brainer.
Yes the Maxwell cards are nice but they are overpriced. Be it 750 or 9x0.

AMD APU processors suck. The performance is abysmal compared to G3258 cpu. I already have a video card so I don't need the integrated video chip. It's going to be better than the onboard graphics anyway and it's a Maxwell card so low heat/ performance is good enough compared to onboard.

I'm not looking at AMD hardware until they put out something that is worth considering.

'Not in the USA, also, so all the good deals there don't apply to me, unfortunately.

Me neither. Here the AMD combo is around $500 instead of $330 biggrin.gif
Intel even worse, those went up since I bought mine...
G3258 I don't like it, it has no power, an i3 is better performance/value.
And the FX6300, will probably blow both away and for less money. Plus it can be overclocked and has 6 true cores.
G3258 overclocked gets closer to being usable but that's about it.

I have 4690K and the cores rarely get used to max, so having more cores is beneficial for normal use I have found. For games, yeah oh well, games, they run a little better on Intel and on high clocked cores and don't need more than 1-2 cores, some games start to use up to 4 but don't run them hard. It's hard to find stuff in games to run in parallel since most stuff like AI, audio, physics are still stuck in the 90-00s and graphics needs just one core.

I've spotted a few things here...
You say the G3258 has no power, but yet you say a 4690k doesn't get used to the max. The Pentium is essentially a dual core i5.
The 6300 doesn't have 6 true cores, it's a 3 core with CMT. Just like the i3 is a 2 core with SMT.
If an i5 doesn't get used to it's max, and i3 certainly won't either. They both require 4 threads to max out.
Finally, unless an i3 is a decent amount cheaper, the Pentium is a better buy. It can be overclocked high enough and easily enough to out power the i3. HT only adds about 25% of the CPUs total performance. This means an i3 is basically 2.5 cores of a Pentium. What happens if we clock a Pentium to 4.4GHZ?

I'm going to get something to eat. I could have phrased this a bit better... but I'm distracted and hangry. Don't mind the 'sharp' tone.

EDIT: You mention price differences. I'm guessing you aren't in a major European country or US/Canada. I know prices can get really messed up elsewhere.

Also, I would plan on upgrading the cpu eventually. The G3258, where I am, is about $70. The AMD cpu compared here is over $100 so it doesn't make sense to later upgrade unless prices have fallen? The Intel processors are also way more power efficient from what I can tell. At least, the most recent generations in comparison (at the time of this post).

Power efficiency for CPUs here is basically and extra $20 a year to run an 8350 at 4.5GHz vs this i5. I know that will be much different in different countries.

If you are on a budget and you cannot do an i5, then if you need single threaded performance the G3258 at 4.5GHz is going to be amazing. If you need total CPU performance then grab a 6300. The 6300 will need after market cooling to overclock. Also, some boards limit the Pentium's overclocking. Some "H" boards have a limit of 1.25V for example.

How inrush current of a PSU is determined?

For example the review of the Cooler Master VS550 here:


http://www.techpowerup.com/reviews/CoolerMaster/V550S/5.html

This review says:
"Inrush current or switch-on surge refers to the maximum, instantaneous input-current drawn by an electrical device when first turned on."

I checked Wikipedia and the maximum means a pick value:


http://en.wikipedia.org/wiki/Inrush_current

But does it depend on the hardware installed? Does it mean that such inrush current will be when system will request all 550w just from start? Or such inrush current will be requested always with any configuration of the system?
post #5139 of 6741
In SMPSs the inrush current is proportional to the capacitance of the bulk caps: the bigger the bulk caps, the higher the inrush current.

More powerful PSUs have larger bulk caps and hence experience higher inrush currents.

Ok, so I bought Cooler Master VS650.

Inrush current of the 550w model is:

http://www.techpowerup.com/reviews/CoolerMaster/V550S/5.html

Inrush current of the 750w model is:

http://www.techpowerup.com/reviews/CoolerMaster/VSM750/5.html

So, for the 650w model inrush current must be between 39.65A and 41.60A?

The TPU review says about the 750w model:
"Inrush current was definitely on the high side for a 750 W unit, but not too high overall since it stayed close 40 A and below 50 A."

But 41.60 is more than 80% of 50A. Probably for the 650w model inrush current is about 40A, but anyway it is 10A near the critical value. How really dangerous is such inrush current? Will it be a risk every time to turn on the PC? How to be sure that house electricity system can handle 40A of the inrush current?
