How big of a PSU for my rig.

post #1 of 19
Thread Starter 
I have a

AMD FD8150FRGUBOX FX-8150 Processor - Eight Core, 8MB L3 Cache, 8MB L2 Cache, 3.60GHz (4.20GHz Max Turbo), Socket AM3+, 125W, Fan, Unlocked, Retail

EVGA 02G-P3-1469-KR GeForce GTX 560 Superclocked Video Card - 2GB, GDDR5, PCI-Express 2.0 (x16), 2x Dual-Link DVI-I, Mini-HDMI, DirectX 11, Dual-Slot, SLI Ready, Overclocked

M5A97 Asus mother board using gigabit and audio off of it.

120gb OCZ ssd

blueray RW drive

2Tb standard HD

32gb of Patriot ram in 4x 8gb dims 1600mhz

Also have a beefy cpu cooler for the processor and its a HAF cool master case with about 3 massive fans on the case.

Currently had a 500Watt PSU in the computer fairly sure it's too low for this though haven't done anything with it yet as I was away for most of the weekend since I got the parts.

So how big of a PSU do I really need to stress these specs out.

What 500W PSU do you have?

First off welcome to OCN . I would go with 650 , and maybe something a little higher if you plan on doing any future adds.

Cooler Master eXtreme Power Plus RS500-PCARD3 500-Watt US Power Supply - ATX, 12V, 120mm Fan, RoHS Compliant

Maybe that one, bought it 2 years back or so, not positive on that but I think that's the one.

I would get a quality 600W from a company like Seasonic, Corsair, or Enermax. 600W will be plenty.

Is it running in the system now? What makes you think it is not powerful enough?

Alright thanks reason Im asking is in Guild Wars 2, max settings Im getting 45fps with some minor scroll lag which should not happen where as I made a smaller rig for my girlfriend recently but put a 750 W psu in it, and it's running 45 fps extremely smooth on max settings and like 90 fps on lowest settings where as my rig is getting only around 55-60 on lowest settings.

I really only can see this being the PSU otherwise im baffled lol

I do not think your PSU will have an effect on performance like that. Are you sure they are running the same resolution? A weaker system could run a lower resolution at max settings while a more powerful system would struggle with a higher resolution at medium settings.

That's a horrid unit, it's an overrated ~350W AcBel low end.

A good 500W would have been plenty for that system, sadly what you have there is a cracker. What is you PSU budget and where are you buying from?

tigerdirect. and I put this one in my girlfriends lesser system and like I said I was very very impressed with the performance

That's complete and utter crap as well... it's an overrate <500W unit, a very poor one too.

Nothing particularly interesting (price wise) on offer at tigerdirect.ca
Any other options (newegg, ncix, etc)?
