Hi, i asked this question before on another forum but would like a second opinion. Here are my PC's specs, i just got it a few days ago.








And a DVD-RW drive

Is the PSU good enough to power my system? i ask because the last forum suggested a 550w but i got a 520w instead because it was modular and the 550w was sold out, they are saying the 520w isnt powerful enough for my system but i'm running it right now without any problems.

A few minor questions and notes:
In my old pc it could power itself and the ATI Radeon HD4850 with barely any problems, thing is... it only had a 300w psu, how did it work?


And to anyone from the "last forum" who might stumble upon this, thanks for all the info, it was a great help but i need a second opinion on this PSU and my system

Honestly a 300 Watt PSU is cutting it close for that system, I'd recommend getting this power supply to be safe and to allow some flexibility in future upgrades. But no, you don't really need a 500+ Watt PSU... I built a system with an i5 2400 and a 6850 with a 400 Watt PSU and it's running like a dream.

For a system using a single Radeon HD 4850 graphics card AMD specifies a minimum of a 450 Watt or greater power supply. The power supply should also have a combined +12 Volt continuous current rating of 24 Amps or greater and have at least one 6-pin PCI Express supplementary power connector.

Your SeaSonic M12II-520 Bronze, with its +12 Volt continuous current rating of 40 Amps and one 6-pin and one 8-pin PCI Express supplementary power connectors, is more than sufficient to power your system with a single Radeon HD 4850.

I can see a high quality 300 Watt power supply with a strong +12V rail not having any problem running a system with a single Radeon HD 4850.

OK, thank you very much for the info, that put my mind at ease somewhat, but i have another question if i'm allowed.

About how much can i safely overclock my e5700 power-wise? I'm shooting for 4.00GHZ or so.
Also, can my mobo support another stick of the same RAM as in my specs listed in the OP?

Thanks.

Your SeaSonic M12II-520 Bronze has so much spare capacity that you can overclock both the CPU and GPU to anything you may want to try that works.

The maximum overclock for your system can only be determined through trial and error. You may shoot for 4 GHz but there's no guarantee that you will be successful but then again you may get lucky and have no problem reaching it.

The ASRock G41M-S3 has two DIMM slots so it'll handle another Crucial 2GB 240-Pin DDR3 SDRAM DDR3 1066 (PC3 8500) Desktop Memory Model CT25664BA1067.
